Mee ng of NANO Alumni with the Nippon Founda on and POGO members Dr. Yuna Zayasu1 and Dr. Arvind Singh2 Post Doctoral Scholar, Okinawa Ins tute of Science and Technology, Japan Wikipage: h p://www.nf-pogo-alumni.org/~Yuna+Zayasu 2 Faculty, Physical Research Laboratory, India Wikipage: h p://www.nf-pogo-alumni.org/~Arvind+Singh 1 e, the NANO Alumni, were thrilled when we received a invita on from Dr. Vikki Cheung on behalf of the POGO Execu ve Director to par cipate in the 17th POGO Annual Mee ng and the side mee ngs that were to be held from 25th to 29th January 2016 in Yokohama, Japan hosted by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC). We happily accepted their invita on. Eight NANO Alumni joined us on the 27th January for our mee ng with the Nippon foundaon and POGO members to present our NANO Projects and how the (Nippon Founda on funded) trainings have benefited our research and career. Mr. Unno and Mr. Ogiue from the Nippon Founda on (NF) and all members of POGO a ended the NANO recep on on the 27th January. Prof. Karen Wiltshire, POGO chair and Vice Director of Alfred Wegener Ins tute (AWI) for Polar and Marine Research, extended her gra tude to the Nippon founda on for providing con nued support for POGO training programs. Mr. Unno addressed us on behalf of Mr. Sasakawa, the chairman of the NF. He introduced NF and its support to POGO ini a ves, and how they aim to educate and encourage children and young fellows to cul vate future leaders in interna onal ocean affairs. Mr. Unno asked us several interes ng ques ons, such as: How and why we got interested in oceanography? What triggered and mo vated us to become oceanographers? What was the most interes ng thing in studying the ocean? It was also interes ng for NANO alumni to hear stories and answers from their fellow colleagues. Mr. Unno told us about Photo taken during the mee ng between NANO Alumni and POGO the importance of networks of people, friends, collabo- Execu ve members rators and co-workers. He said that this partnership will complement our strengths. With that, he concluded the first half of the NANO recep on. A erwards, other POGO members and young scien sts from JAMSTEC joined us. Prof. Shirayama from JAMSTEC opened the poster session with a brief introduc on of NANO members and young scien sts who presented posters. The poster session was held in a relaxed and friendly atmosphere. Our posters were about the NANO and its regional research and outreach projects. Further, all of NANO par cipants gave short talks about the benefit they have experienced from the POGO training program, current research interests and their involvement with the network. We spent one a ernoon on RV Mirai, the Japanese research vessel. It is considered one of the largest research vessel of the world. We were shown chemical analysis laboratories, a weather sta on and various instruments used on the ship rou nely. Finally, we were happy to meet other NANO Alumni who had a ended the CofE at the Bermuda Ins tute of Ocean Sciences or other NF-POGO courses. It was a great way to bring together people who we know via online chat or google group emails. It was a four-day great reunion of a family that has spread to every corner of this globe and is commi ed to ocean research and collabora on. We hope to con nue this way in future.

NF-POGO CofE Meet the new Pogonians Pogonians year 7 (2015 - 2016) Compiled by Mr. Mahmudur Khan *Check the alumni wikipages at h p://www.nf-pogo-alumni.org/CofE+Alumni#x2015-2016 Galina Abyzova (Russia): Galina is specialized in invertebrates, she has a Bachelor and a Master degree in Zoology from the Lomonosov Moscow State University. In her master thesis, she inves gated zooplankton community composi on and the influence of the frontal structure Antarc c currents on the distribu on of small-size copepods in the Antarc c Ocean (Drake Passage). And now she is doing her PhD at the Shirshov Ins tute of Oceanology in Moscow about arc c mass species of copepods. She is inves ga ng popula on structure in the Kara Sea and poten al hybridiza on between Calanus species in the Arc c. Galina’s research interests focus on the changes occurring in the Polar Regions due to clima c shi s and how plankton communi es respond to hydrophysical processes. She has more than five years of extensive experience in the field and is experienced in laboratory study of freshwater and marine science. Galina expects from the program NF-POGO CofE-AWI to get new knowledge of hydrophysics and biochemistry to study the func oning of the ecosystem and biological processes in the ocean. She is grateful to have the opportunity to study at AWI and learn from experts in oceanography. Katherine Amorim (Brazil): Katherine is from São João da Boa Vista, Brazil. She has studied Biological Sciences at Universidade de São Paulo (USP), Brazil. Her first research experience within marine ecology was in experimental trophic ecology of rocky shores at the Centro de Biologia Marinha of USP. In that project she has tested avoidance risk response of gastropod according to different food items under predator exposi on. A erwards, she has done a survey a emp ng to find a rela on between different shell morphologies of snails and density of crabs at rocky shores through a scien fic project. A er comple ng her undergraduate degree, Katherine has worked as a volunteer technician in a project of frequency-dependent selec on of guppies at the University of Toronto. Later, Katherine worked on a rocky shore survey of biodiversity in the South America Research Group on Coastal Ecosystems in Brazil in their 2013 campaign. Finally, her last experience with sciences was during her master thesis at Universidade do Algarve, Portugal. She has performed experiments tes ng the hypothesis that using freshwater pulses from a hydro-technical structure (Dam) could be a promising ecohydrological approach for controlling jellyfish blooms. She is now taking part in the NF-POGO Training course at the Alfred-WegenerIns tute. She is very thankful for having the opportunity to develop her skills in sciences with great scien sts. She is interested in improving her skills in experimental ecology, to understand new areas in oceanography such as physical and chemical modeling and how environmental variables affect biota. Shahin Badesab (India): Shahin is from Goa, India. Her Masters is in Marine Sciences, from Goa University, India. For her thesis, she worked on “Study on macrofaunal density and ver cal distribu on of meiofauna in mudflat of Goa”. Therea er, she joined the Na onal Ins tute of Oceanography (NIO), Goa, India as a project assistant and worked in various environment impact assessment projects wherein she was responsible for carrying out the sampling and analysis of benthos at the laboratory. A er ge ng a Senior Research Fellowship from the Council of Scien fic and Industrial Research, Delhi in 2011, she registered for a PhD in Marine Sciences (Goa University) to work on the topic ‘Macrofauna community structure in the hypoxic zone over the Western Con nental Shelf of India’. Being at NIO, she has good experience of working at sea. She strongly believes that the NF-POGO CofE program would provide her the great opportunity to interact with experts, and also opens avenues for networking in the oceanographic field. She is confident that this NF-POGO CofE program will greatly enhance her understanding in oceanography, help her approach research from different perspec ves and further her passion for oceanographic research. A er returning to her home country, she wishes to con nue her research on benthic ecology with her exis ng exper se and incorpora ng the new found skills that she will have receive from this program. Meri Bilan (Croa a): Meri has done her Master thesis within an Erasmus internship program in Laboratorio Marí mo da Guia in Cascais (Portugal) while enrolled in the master program of University of Split (Croa a). Her master thesis is focused on the ontogenic development of photosynthe c sea slug Elysiaclarki in the climate change scenario. A er finishing classes in 2015, she moved to Azores (Portugal) to par cipate in the MIDAS project. There, she focused on the experimental study of the impact of deep sea mining on benthic fish. With this work she decided to pursue her dream in deep sea research where she finds the NF-POGO to be very suppor ng and helpful. Un l now, the POGO program has enriched her life with so many nice people, either professors from which she learns so much every day or new family of POGOnians who are there for her always.

NF-POGO CofE Hiroshi Inoue (Japan): Hiroshi researched phylogeography of the spiny lobster (Panuliruspenicillatus) using molecular analysis for his undergraduate degree at Ryukyu University, Okinawa, Japan. Then he got a master’s degree from Kyoto University on an ecosystem model using Ecopath with Ecosim. His master thesis focused on coastal marine ecosystem model with fisheries. While he was a master student, he studied Ecopath with Ecosim so ware at University of Bri sh Columbia. He presented his work at the Ecopath interna onal conference and workshop in Barcelona, 2014. A er ge ng his master degree, he con nued to study the marine ecosystem with a wider range in marine ecosystem as a PhD student in Kyoto University. He is so proud of joining the POGO program. He studied the biological field well but not the physical or chemical field. So the NF-POGO CofE program is a great opportunity for him to enhance his knowledge. Mahmudur Rahman Khan (Bangladesh): Mahmud is a young oceanographer who aims to build capacity in scien fic-economic aspects and to develop future perspec ve strategies for mankind answering the three ques ons – ‘What, Why and How?’ concerning the changing ocean. He has a MSc degree in Oceanography from University of Dhaka doing his thesis on plankton dynamics and primary produc on of the Bay of Bengal. His earlier three years of research experience include both field and laboratory level experimental work. Previously, Mahmud has pursued his Bachelor and a first Masters in Fisheries from the same university with a thesis work on salinity intrusion effects in the coastal areas of Bangladesh. The main objec ves of his research are to deal with requisite ecosystem processes and func ons, and to learn ocean modelling for understanding the mechanism of the ecosystem as a whole. So, by way of the NF-POGO program in AWI, Mahmud wishes to learn more on oceanographic research by going through the interac on with interdisciplinary communi es, and by having hands on prac cal works, tours, excursions and expedi ons as well. He expects a research project in biogeochemical modelling coincided with marine ecosystem, which will indeed endorse his skills in this discipline for his future career and his intended PhD study. He hopes this POGO program will be very helpful for the growing scien fic umbrella in oceanography and for his country as well. Mahmud finds a global village of scien sts in AWI from which he is learning every minute, and also makes friends from different parts of the world being a happy family! Baye Cheikh Mbaye (Senegal): Baye is a na ve of Rufisque (Senegal) and a coastal-environment lover since his childhood. He holds a Master in Meteorology and Oceanography from the Cheikh Anta Diop University of Dakar where he dealt for the first me with coastal biogeochemical fields related to upwelling dynamics within the produc ve Senegalese coast. Then naturally, he started a PhD in physical-biogeochemical-ecological oceanography where he studied the role of environmental effects on the spawning strategies of sardinella, the main small pelagic fish along the Senegalese-Mauritania coastal region (southern part of the Canary Upwelling System). He received his doctorate degree from both the University Pierre and Marie Curie (Paris) and the University Cheikh Anta Diop (Dakar). His research interests are the study of the interacons between physics, biogeochemistry and the marine ecosystem, and are primarily based on regional, bio-physical and numerical modelling. Baye aims at becoming an ocean research leader in Senegal and believes that the NF-POGO CofE will help him to shape this goal by gaining experience in presen ng to and learning from specialists in a wide variety of fields within oceanography. With frequent contacts with both marine observer and modeler offered by the NF-POGO, Baye plans to create a network for monitoring the poorly documented but rich upwelling region of Senegal. This will help to understand the mechanisms of fish popula on dynamics for marine management and conserva on of this area where fish plays a central role for food security and economic income. Aina Le Don Nomenisoa (Madagascar): Aina is from the southern part of Madagascar. He got his BSc in Marines Sciences at IHSM (Ins tut Halieu queet des Sciences Marines), University of Toliara. Then, he pursued his studies in the University of Reunion Island, where he earned his MSc in Remote Sensing. Aina is interested in Earth Observa on data processing and handling. The POGO program will help him to sharpen his knowledge and to acquire some mul disciplinary oceanographic skills. His latest scien fic experience was on board the research vessel of Fridtjof Nansen, in the context of the IIOE-2 (Interna onal Indian Ocean Expedi on). Aina also expects from the program to hang out with scien sts who are willing to help him to process the data they collected during the research cruise he was included in. Frances Camille Mendoza Rivera (Philippine): Mabuhay! Meaning Long live, which is the usual gree ng in the Philippines. Camille graduated with an Interna onal MSc (formerly known as Erasmus Mundus) in Marine Biodiversity and Conserva on in a consor a of universi es coordinated by Ghent University in 2014. She did her thesis on the biodiversity and ecosystem func oning of the diatom community and a single copepod when exposed to copper (heavy metal) and atrazine (herbicide). A er her MSc studies, she returned home to work as a research assistant in a na onwide project on the upscaling of seaweed produc on in the Philippines. The goal of the project is to create a GIS-based database on the extent of the seaweed farming and prac ces. Another goal is to bridge the knowledge gap to find be er methods for the progress of the seaweed industry. She believes that joining the NF-POGO CofE at AWI will sharpen her scien fic and prac cal skills in different aspects of oceanography and enable her to expand her knowledge and share it when she gets back home, with 4 Contact us: tedwango10@gmail.com, info@nf-pogo-alumni.org, lilian.krug@nf-pogo-alumni.org NANO website: www.nf-pogo-alumni.org

NF-POGO CofE a future plan to form a marine conserva on based NGO. Furthermore, the network of scien sts will be very useful for her future scien fic research. Senam Kofi Tsei (Ghana): Senam is from the land of Gold called “Ghana”. He holds a Master’s degree in Applied Marine Science (physical oceanography op on) from the University of Cape Town. His disserta on was en tled “An inves ga on into the sampling bias of Argo float in Southern Ocean”. His master’s degree thesis aimed to address the following ques ons: What is the spa al distribu on of the Argo profiling floats in the Southern Ocean south of Africa? Is the spa al distribu on of the Argo profiling floats influenced by the bathymetry or by the surface geostrophic veloci es in the Southern Ocean? To answer these ques ons, the posi ons of the Argo profiling floats were co-located in space to the ETOPO2 bathymetry and to the surface geostrophic veloci es to understand whether the distribu on of floats was influenced by the bathymetry or by the surface geostrophic current veloci es. He would like to con nue in the field of physical oceanography (now and in future) with interests in ocean dynamics (currents, waves, fronts and eddies), air-sea interac ons, water masses, ocean telecommunica on, ocean and atmospheric modelling, bio-physical interac ons and biogeochemistry of upwelling systems. This is because the aforemen oned exper se are lacking in his home country and sub-saharan countries. Pogonians Year 7 (2015-2016): From le in the back row are Baye, Hiroshi.

Shipboard training The Opportunity of a Life me: the 2015 NF-POGO Students and the North-South Atlanc Transect Floa ng Summer School aboard the RV Polarstern *The alumni profiles will be available soon at h p://www.nf-pogo-alumni.org ive weeks, 13000 km, north to south down the Atlan c Ocean from Bremerhaven, Germany to Cape Town, South Africa: the PS95 North South Atlan c Transect (NoSoAt) took 32 graduate students from 19 different countries on the adventure and learning experience of a life me! Chosen out of 490 applicants, seven African students were funded by NF-POGO to a end the NoSoAT Summer School aboard the German icebreaker vessel RV Polarstern. We arrived from all four corners of the world in Bremerhaven on the 28th October 2015. On the first day, we visited the AWI Building in Bremerhaven, where a welcome address was read on behalf of Prof. Dr. Karin Lochte (Director AWI) by Prof. Dr. Karen Wiltshire (Chair of POGO) and Dr. Pauhla McGrane The NF-POGO African students in Bremerhaven, Germany, about to board the RV Polarstern. (Na onal Coordinator of SMART). We, par cipants, then introduced ourselves briefly, sta ng our research backgrounds and home country. A plenary lecture was delivered by Prof. Peter Lemke on the topic ‘The Climate System and the Oceans’. On a guided tour to the AWI laboratories we had the opportunity of seeing the ice cores drilled from the Ar c and Antarc ca (the oldest of which were 800 000 years old!) and learnt how the ice core is extracted, processed and dated. On 29th of October 2015, filled with high hopes and expecta ons (and a li le nervous), it was me to board! A er being allocated cabins and cabin mates, we had a general mee ng and safety drills. We were then separated into five groups that should be follow each of the five course sec ons: Oceanography, Zooplankton, Phytoplankton, Remote Sensing and Tools. F Oceanography We received hands-on training in the prepara on and launching of expendable bathythermographs (XBT’s), which we deployed each day at 9 am. We also learnt to prepare and deploy the Conduc vity Temperature Depth (CTD) profiler, and how to process and filter the samples brought back from the CTD. We worked with the photosynthe cally ac ve radia on (PAR) sensor, prepared and deployed the BBE Algae analyser during each chlorophyll maximum CTD cast. This was further complemented by data extrac on, processing and visualisa on in SeaBED and Ocean Data View (ODV) so ware. Our understanding of these diverse methods was tested when we, the students, conducted a full sta on oceanographic sampling and processing unassisted (no teacher involvement)! Phytoplankton Since our transect aboard the RV Polarstern crosses a rela vely understudied area of ocean, especially with regards to phytoplankton, the cruise provided students and researchers alike with the opportunity to examine phytoplankton communies that has never been studied before. Sampling itself involved taking bucket samples every morning at 9 am, as well as deploying a 20 μm and 80 μm phytoplankton nets at every sampling sta on. The samples collected were used to build up a species community composi on list along the transect, as well as for phytoplankton counts. Students were also trained for the development of the iden fica on keys methods. Zooplankton We were shown how to set up and deploy the con nuous plankton recorder (CPR), an exci ng prospect especially since the NoSoAt Floa ng Summer School was the first me that the CPR was deployed on a regular basis for the en re transect we crossed. We also deployed ver cal and horizontal bongo nets as well as CalCOFI (California Coopera ve Oceanic Fisheries Inves ga ons). Nets at each sampling sta on, comple ng zooplankton counts from each one of these samples. Lastly, algal growth experiments and grazing experiments were conducted each week tes ng various factors that may influence how well algae grow in different environments.

Shipboard training Remote Sensing The Scholars One of the important features of the ocean is its colour, which can be related to phytoplankton biomass. This was introduced to us by using RAMSES measurements, were we used light proper es to determine water proper es. These measurements were used to determine the reflectance which gives informa on on the water transparency and colour, and this can be used to deduce the produc vity of that region. We learnt how to use the BEAM VISAT so ware developed by the European Space Agency to extract and map satellite data for various ocean colour parameters (such as Chlorophyll–a) and how to import, plot and interpret our measured RAMSES data in Python programing so ware. Tools Pavanee Annasawmy Mauri us. Joint PhD degree at the University of Cape Town, the University of Montpellier & the University of Mauri us The tools group was set up to equip students with vital life skills that may be useful in any young academics’ life. Some of the topics addressed were project management, me management, scien fic and ethical skills and how to publish a peer reviewed paper. The tools group also provided students with some much needed down me, me used for more fun, crea ve projects, but also to bond and get to know each other. Mohammed Kajee South Africa. BSc (Honours) Marine Biology (2015) from the University of Cape Town Our home and classroom for 5 weeks - the RV Polarstern In terms of our overall experience and what we gained, we all felt that we had grown as both marine scien sts, and in our personal capacity. While we learnt about good scien fic prac ce, gear deployment, sample collec on, data processing and analysis, we also built up our scien fic confidence by installa on of a sta on on our own and by wri ng a scien fic ar cle summarising and analysing a por on of the data collected aboard in three days. We, the students, greatly learnt from each other. All students aboard had different exper se, backgrounds and experiences, and we thus complemented each other’s knowledge by sharing our knowledge about so ware such as Primer, BEAM VISAT, ODV, GIS to our own peers. We gave individual presenta ons each evening about ourselves and our work, which allowed us to gain more insight into the biological, physical and chemical oceanography projects that were and are s ll being carried out all around the world. On a more personal level, we, 32 people from 19 different countries, learnt how to cooperate, collaborate, work together as a team, support each other in our bad mes, care for each other and build tolerance and acceptance. We were put together as individuals and strangers with different backgrounds, cultures and exper se, but in the end, we le the RV Polarstern as one big family. We will each be taking this experience and what we have learned back to our home countries and ins tu ons, and use it to further marine science in Africa. We are all scheduled to present on the skills and results acquired aboard the NoSoAt Summer School at our respec ve ins tuons in 2016. Amy will be introducing “three minute thesis speed presenta ons” at her home ins tute, to improve and foster postgraduate rela onships and interac ons, and will be presenting a module to the masters class on data management and the use of BEAM VISAT. Edem will be using some of the data collected for the training of undergraduate students. Zo will be presen ng to the members of YSO Madagascar, and will include a write up of the trip through the trimestral new paper of the “RANOMASINA” ins tute. As a whole, the Floa ng Summer School was an experience of a life me.

The highlight of this trip, without doubt, was mee ng likeminded students from all around the world. Ge ng to learn about different cultures from our fellow students and the obstacles that they face as young academics in different parts of the world, and most importantly, gaining insight into the vastly differing fields of research that each student brought onto the expedi on was an invaluable experience.

NANO OUTREACH Outreach ac vi es Dr. Kanthi K.A.S. Yapa h p://www.nf-pogo-alumni.org/~Kanthi+Yapa University of Ruhuna Matara, Sri Lanka Seminar and poster exhibi on, “Ocean is our Neighbour” n outreach programme was conducted at Rohana School, Wellamadama, Matara, Sri Lanka for students in grades 8, 9 and 10 on November 30th 2015. Rohana School is situated in the close proximity of University of Ruhuna, Matara and it is a mixed school, having both girls and boys in each classroom. A seminar and a poster session on the topic “Ocean is Our Neighbour” was done by Kanthi K. A. S. Yapa, Faculty of Science, University of Ruhuna, Matara for about 50 students in grades 8 and 9. Students were introduced to general topics related to earth, ocean and atmosphere and the processes that contribute to the water cycle and carbon dioxide cycle in some detail. The ocean resources, marine and plant lives and how their well-being is important to the well-being of the planet earth as a whole was also discussed in great detail. How to respect, care and protect our ocean neighbour was emphasized at the seminar. About 25 posters depic ng many aspects of the life on the planet earth and the importance of caring and protec ng our ocean neighbour, such as how earth, atmosphere and ocean are inter-connected, why the health of marine life, corals and plankton are important to man, how plas cs and pollutants destroy ocean life, etc. were displayed using both Sinhala and English language. The students were very apprecia ve of what they learned through the seminar and posters. A Between 13th and 14th October, 2015, a poster exhibi on tled “Ocean is our Neighbour” was held in the Faculty of Fisheries & Marine Science and Technology, University of Ruhuna, Matara in parallel with the educa onal exhibi on held to promote the Fisheries & Marine Science programme. About 15 posters depic ng many aspects of life in the ocean were exhibited. Titles of some posters were, “Importance of Protec ng Marine ornamental fish”, “Deple on of marine fishery resources due to overexploitaon”, “Marine debris: A threat to the marine environment”, “Instruments used in Physical Oceanography”, ”Coral reefs are vanishing”, “Marine Mammals of Sri Lanka”, “Threats to sea turtles”, “Marine invasive species”, etc. While some posters aimed to educate the students with informa on about ocean life, others were there to give a strong message to reduce/ avoid anthropogenic ac vi es that lead to damage of marine habitats and reduc on of fishery resources. Some posters had been prepared in local language, Sinhala as it is the mother language of the great majority of the exhibit visitors. Several undergraduate students from the faculty, W.E.K Wijesinghe, K.B.S.S.J Ekanayaka, U.P.G. Pathirana, H.M.S.M Wijerathne, H.S.A He arachchi, S.A.A. Prasad, M.D.M. Faazil, A.A.M.D. Ranasinghe, Dr. Kanthi Yappa delivering a talk for the 8th and 9th G.E.D. Jayalath and W.P.J. Sathyadith as well as faculty members, K. R. Ga- grade students. mage, H.B. Asanthi and H.B. Jayasiri contributed in the prepara on and presenta on of the posters. Hands-on workshop on “Coastal Ocean Biodiversity” On the same day, a hands-on workshop was conducted for 20 students in grade 10 of the Rohana School on the topic “Coastal Ocean Biodiversity” by H.B. Asanthi, H.B. Jayasiri and demonstrators, H.M.U. Ayeshya and D.M.K.K. Dassanayaka from Faculty of Fisheries & Marine Sciences and Technology, University of Ruhuna. At the workshop, students had the opportunity to touch, feel as well as observe, through naked eye and through a microscope, some specimens/ samples from the coastal ocean. Characteris c morphological features, habitats, adapta ons and ecological importance of selected marine flora and fauna were briefly discussed. Some important and interes ng examples were explained, such as: macro algae - red, brown and green algae; mangroves; invertebrates - corals, crabs, lobsters, sea stars and sea urchins; sponges and vertebrates – turtles and sea snakes. Students had the opportunity to learn using life as well as preserved samples. Students asked ques ons related to marine flora and fauna and each was given an exercise to write iden fica on features of two such species. Students par cipated very ac vely through the whole programme, which lasted for about three hours.

Despite difficult field work condi ons, two de-wave gauges were successfully deployed in May off the coast of Jerba island on the southeastern Tunisian coast, and at the entrance of the Viridi channel off the coast of Abidjan in Ivory Coast (Figure 1). The sensor was recovered from Tunisia in October and a 109 day-long me-series of wave parameters, depth and pressure fluctua ons was retrieved. A portable weather sta on was also installed in July, by the project par cipants in Ivory Coast, near the de-wave gauge mooring site in Abidjan harbour (Figure 2). Technical issues encountered during the setup of the portable weather sta on prevented project par cipants in Tunisia from deploying their weather sta on. These technical issues are currently being addressed with the weather sta on manufacturer. Nevertheless, a two-month long me-series of wind speed and direcon, concurrent with the de-wave gauge deployment period, was obtained from the Tunisian Na onal Ins tute of Meteorology. The me-series of the significant wave height and water column depth obtained at the Tunisian study site is presented in Figure 3. A harmonic analysis applied to the pressure-derived sea level me-series showed that the dominant dal harmonic cons tuent in the Gulf of Gabes was the semi-diurnal cons tuent (M2), with an amplitude of 30.9 ± 0.70 cm and a phase rela ve to UT of 72.85 ± 1.14 degrees. Applica on of Del 3D to flow simula on (DELFT-FLOW) In addi on to the descripon of the hydrodynamic and meteorological condi ons at the selected study sites, the me-series data from the observa onal equipment were used (along with bathymetric xyz data) to ini alize and prescribe boundary condi ons for DELFT-Flow (hydrodynamic engine) numerical model. The simula on results for the current and the sea level are presented for Ivory-Coast, Tunisia and Brazil (Figure 4). The progress made in the modeling work was made possible by the par cipa on of NHG members in the internaonal workshop “Introduc on Figure 1 - Deployment of the RBR/D-Wave sensor off (top) the northern coast of Jerba island, Tunisia to numerical modeling with and (bo om) the coast of Abidjan, Ivory Coast.

NANO REGIONAL PROJECTS Spa al and temporal variability of phytoplankton pigments (2012-2014) Progress on the La n America Regional Project (LA NANO) Dr. Adriana Gonzalez Silvera1 and Mr. Abraham Saavedra2 Universidad Autonoma de Baja California, Mexico 1 LA NANO Project Coordinator Wikipage: h p://www.nf-pogo-alumni.org/~Adriana+Gonzalez+Silvera 2 LA NANO Fellowship Holder Email: abraham.saavedra@uabc.edu.mx he La n America NANO Regional Project (LA-NANO, h p://www.nf-pogo-alumni. org/La n+American+Regional+Project) began in 2012 with the objec ve of implemen ng pigment analysis using HPLC in the ANTARES network me-series sta ons (h p://www.antares.ws). It involves seven countries and seven me-series sta ons around La n America and the Caribbean (Figure 1, Table 1). One of the objec ves of the ANTARES network is the study of the temporal varia ons in phytoplankton communi es. Phytoplankton func onal types (PFT) are groups of phytoplankton species that have specific roles in the biogeochemical cycles and trophic flow. These groups have been pointed out as keys to improve the knowledge on ecosystem dynamics and effects of climate and anthropogenic changes in the marine environment. High Performance Liquid Chromatography (HPLC) is a technique that allows the descrip on of pigment concentra ons in water samples and is an effec ve method for PFT studies. However, HPLC analysis requires not only specific equipment but there is also the need of applying the correct methodology to assure the genera on of high quality data for the scien fic community. Taking this in mind a series of mee ngs were organized to give the opportunity to the LA NANO project members to learn from experts and enhance their exper se in this subject. In addi on, an agreement was signed with the Ocean Ecology Laboratory, NASA-Goddard Space Flight Center (Greenbelt, Maryland, USA) and samples collected in each sta on were analyzed to determine phytoplankton pigments. At this moment we will report the informa on that is being analyzed from data collected from 2012 to 2014 which gave us the possibility of looking, using a biogeography point of view, how the phytoplankton community is changing in space and me. Here it is important to consider that this study considers the analysis of data from two sta ons in the Atlan c Ocean (Argen na and Brazil), two sta ons in the Caribbean (Venezuela and Colombia), one sta on in the South Pacific (Peru), and one in the North Pacific (Mexico). Each one has its par cular oceanographic characteris c going from very oligotrophic regions to eutrophic zones such as the Peruvian upwelling system. In addi on, monthly MODIS/Aqua Chlorophyll a (Chla) me-series were analyzed (Figure 2) to have a con nuous picture of the temporal variability, considering that in situ sampling was not possible in a regular frequency. It is interes ng to note that we had to group some sta ons according to their range in variability . Brazil, Colombia and Mexico were grouped together, with Colombia being the sta on with the lowest Chla as expected in a region located in the Caribbean. Venezuela and Argen na are those with intermediate concentra ons, although the reason why Chla in Venezuela increased so much during the first six months of 2014 will be a ma er of study. Finally, Peru was analyzed separately because it presents very high Chla that especially during 2014 increased to up to 18 mg/m3. This informa on gave us the first insight into the spa al and temporal variability of phytoplankton biomass at the ANTARES sta ons. However, as men oned before, the informa on obtained from HPLC analysis allows not only the evalua on of phytoplankton biomass but also of phytoplankton community composi on. This is because some phytoplankton pigments are biomarkers of some phytoplankton groups (Jeffrey et al., 1997), some are specific to one phytoplankton group and others are characteris c because they are present in various phytoplankton groups. The informa on obtained is being analyzed to evaluate phytoplankton richness (biomass and diversity) at the different ANTARES sta ons and its rela onship with some physical and chemical characteris cs of each environment. For example, the pigment Fucoxanthin (Fuco) is characteris c for diatoms and the mespace variability of the ra o Fuco/Chla indicates its high importance in most countries, its propor on being the lowest in Colombia (Figure 3). To the contrary, in Peru the ra o Fuco/Chla is always high, which is to be expected considering diatoms as a characteris c group in upFigure 1 - Study area with the indica on of the posi on welling systems. The Mexican sta on is also located in an upwelling of the ANTARES sta ons that are par cipa ng in this region (California Current) but seasonal cycles regulate the upwelling project. Sites are superimposed on a MODIS/Aqua Chla intensity, which explains why the ra o is much lower than in Peru. image from December 2014 T Contact us: tedwango10@gmail.com, info@nf-pogo-alumni.org, lilian.krug@nf-pogo-alumni.org NANO website: www.nf-pogo-alumni.org 13
