"> Dispatch from the World Seabird Conference in Australia
Last month, PSI staff writer Eric Wagner joined hundreds of scientists from 51 countries to talk about the health of the world’s seabirds. Throughout the conference, the climate crisis loomed large but there were signs of hope in the sheer numbers of dedicated scientists working on seabird protection. By Eric Wagner Seabirds are declining all […]

"> Southern resident orca population increases by two; no adult deaths reported in latest census
The southern resident killer whales — those fish-eating orcas that were once tied closely to Puget Sound — have managed to stay somewhat intact, with no deaths among the adult population for more than two years. As I reported this summer, four new calves were reported during the recent census year, ending in July, but […]

"> Sewage treatment permits being revised to address nitrogen, low-oxygen problems
Regulatory efforts to confront low-oxygen problems in Puget Sound have turned toward sewage treatment plants, as the Washington Department of Ecology proceeds to reissue operational permits, some ahead of the normal five-year schedule. Excess nitrogen has been found to contribute to low-oxygen problems in Puget Sound, and computer models have identified locations where reducing nitrogen […]

"> Annual census could show an increase of two killer whales among southern residents
Pending one final check, it appears that this year’s census of the endangered southern resident killer whale population will show a positive increase of two orcas — an annual increase equaled only four times in the past 20 years. The Center for Whale Research, which conducts the annual census, needs one more encounter with a […]

"> Around the Sound: Scientists hold workshop to discuss threat of avian influenza
By Eric Wagner A few weeks ago, biologists with the Australian Antarctic Program published a study on bioRxiv, a preprint service that allows scientists to share their work before it has been peer-reviewed. The study was titled, “Mass mortality of southern elephant seals during multi-species outbreak of HPAI H5N1 on sub-Antarctic Heard Island.” In it, the […]

"> How Puget Sound became a proving ground for environmental social science
Environmental social science is the study of how people and ecosystems shape each other. Often seen as useful but rarely as essential, it has long played a supporting role in ecosystem recovery. A new introduction to a special issue of Coastal Management, written by Sara Jo Breslow and thirteen co-authors, argues that this position is […]

"> June 30 roundtable explores hatchery effects on trait variation in Pacific salmon
The Salish Sea Science Roundtable online speaker series continues on Tuesday, June 30 from 12:30 – 1:30 pm. Enhancement of Pacific salmon stocks through the use of hatchery production is one approach to support vulnerable stocks and harvest. Integrated hatcheries support these goals by adding artificial spawning habitat to natural habitats, which produces elevated egg-to-release survival […]
