Why do more than 100 gather off Western Australia every year?
A Flinders University researcher has finally fathomed why large numbers of killer whales gather at a single main location off the West Australian southern coastline every summer.

In a new paper published in Deep Sea Research, physical oceanographer Associate Professor Jochen Kampf describes the conditions which have produced this ecological natural wonder of orcas migrating to the continental slope near Bremer Bay in the western Great Australian Bight from late austral spring to early autumn (January-April).
Norway: Authorities and research communities share knowledge about seepage from the seabed
11 May 2021
Causes, risks and effects linked to seepage from the seabed were among the topics discussed at a workshop including participants from the
Petroleum Safety Authority, the
Norwegian Petroleum Directorate and several professional and research communities.
Seepage from the seabed can have many causes. It can occur in connection with human activity or be caused by natural processes. There has been a greater focus on seepage from the seabed recently, where seepage of methane gas from or around wells drilled in connection with petroleum activity has been mentioned and discussed.

The aggregation is connected to the local marine food web that follows from the upwelling of benthic particulate organic matter (POM) in a confined region near the seafloor plateau near the head of the Hood Canyon, says Associate Professor Kampf, from the Flinders University College of Science and Engineering.
