marine mammal rescue exercise in may npws in conjunction with jervis bay marine parks booderee national parks and orrca conducted a very successful exercisewhich was open to the public an area was set up at greenfields beach vincentia where attendees were required to register as if they were attending an incident a brief safety training session was presented by shona lorigan before they proceeded to the beach where they were able to watch a mock rescue take place this presentation was provided by npws with the assistance of steve skinner a huge thank you to all the south coast orrca members

along the beach near calvert cliffs this february during a period of unusually low tides when they spotted something odd it was the top of what is believed to be a 12-millionyear-old skull of the extinct dolphin species lophocetus pappus only the third such specimen ever found the fossil is being preserved and studied by a team of experts led by stephen godfrey curator of the calvert marine museum in solomons although unexpected the discovery didn t come as a shock to godfrey given the area s bounty of fossils from the miocene era which occurred between 8 million and 18 million years ago the cliffs contain fossils from as many as 30 different species of whales and dolphins said david bohaska a palaeontologist at the smithsonian museum of national history bohaska described calvert cliffs as world renowned and said palaeontologists from as far away as new zealand visit them regularly because the fossil was found below the mean high tide in other words it was usually covered by water godfrey didn t have to ask for the property owner s permission to excavate that allowed his team to remove the fossil before it was destroyed by the waves but they aren t always that lucky we re required of course to actually get permission on private land and occasionally we lose something because

people say no bohaska said bohaska has tried to preserve the calvert cliffs coast with mixed success he said he worries that a second generation of landowners will sell their land to developers the result would be the loss of history and present beauty it would be as if you had a book and started ripping pages out of the book and said those pages aren t important godfrey said the fewer pages you have access to the less of that story you are able to tell amazing the miocene era i hadn t even heard of that era or remembered not learning about it back in high school when i was probably

state waters for more than 24 hours defying federal government protests humpback whale songs change tune unexpectedly tuesday march 27 2012 push for whale sanctuary david killick www.themercury.com.au april 16 2012 legislation intended to declare tasmanian waters a whale sanctuary will be debated in state parliament this week greens mp cassy o connor is backing a bill that seeks to close a loophole in the law on whaling in state waters the australia whale sanctuary starts three nautical miles 5.5km offshore and protects whales from that point to the edge of the exclusive economic zone 200 nautical miles out whaling is prohibited in state waters but the greens want the area formally declared a whale sanctuary this would be in line with federal legislation the issue was thrown into sharp focus by the appearance of a japanese whaling ship off world the mystery surrounding the songs of humpback whales megaptera novaeangliae has gotten deeper thanks to findings from researchers in the usa madagascar and ms o connor said a greens western australia private member s bill to be published in the january debated in state parliament 2012 edition of marine on wednesday would offer mammal science the study full unambiguous legal by murray et al is the first to protection to any migrating document whales within the whale visiting coastal areas same ocean basin singing the bill would also make it an almost completely different offence for anyone to help in songs taking whales in tasmanian this is an exception to waters what is usually found many whale watching and when comparing song loving tasmanians would be from breeding sites within surprised to know our waters the same ocean during a are not a whale sanctuary breeding season says ms o connor said researcher anita murray currently at university of i think they will also be queensland s cetacean surprised if either or both ecology and acoustics of the major parties found laboratory a valid argument for not males from breeding sites creating a state sanctuary within the same ocean basin environment parks and usually sing the same song heritage minister brian meaning they sing the same wightman who opposes themes in

australian cultural transmission of song government to set up a between whales from different national network of whale breeding assemblages is not and dolphin sanctuaries as clear as once believed we are also working says ms murray to implement national she speculates the guidelines for managing difference in song could human interactions with be due to interactions whales and dolphins the greens proposal while no doubt well intentioned appears to simply duplicate those protections and [our ongoing work unravelling this mystery will be a challenge involving studying song comparisons from gabon madagascar wa and eastern australia over multiple years to understand the patterns and directions of transmission image noaa between breeding grounds in madagascar and gabon noting 2003 research that found the whales sharing the same song despite being in different basins a similar outcome was found in australian waters in 2000 when western australian song replaced eastern australian song over a twoyear span ms murray believes some geographical overlap occurs in which members of separate basins interact unlike in the northern hemisphere there are no land masses to block this type of mixing in the southern hemisphere different whale assemblages could come into contact with one another during migration to antarctic feeding grounds or during the feeding season itself this study is just the tip of the iceberg in terms of what we have left to discover about the complicated and dynamic cultural transmission of song in the southern hemisphere says ms murray unravelling this mystery will be a challenge involving studying song comparisons from gabon madagascar wa and eastern australia over multiple years to understand the patterns and directions of transmission of course knowing how songs are transmitted still doesn t answer the mystery of whale song itself humpback whale song is a male acoustic display used on winter breeding grounds migration routes and summer feeding grounds page
