A plethora of scientific research reports on climate, oceanography, fish, sea birds, marine mammals and anthropogenic impacts – including by Raven Cunningham de Cordova – were on the agenda of the Symposium de Sciences Sciences Alaska 2025 (AMS) navies.
Cunningham, director of the Tribal Fish and Wildlife for the Regional Resources Commission (CRRC) Chugach, was back in Anchorage. She presented the symposium for the last time in 2023.
Cunningham approached AMSS participants on the work carried out by the initiation of CRRC Chugach IMAQ on the management plans of marine-mammals, who focused on conservation efforts for port seals, the otters of Sea and Steller Sea Lions. The initiative attracted the support of the US Geological Survey Alaska Science Center and the US Fish and Wildlife Service to bring together partners of the Gulf Watch Alaska, the Alaska Fish and Game Department, the National Marine Fisheries Service, from The commission of marine mammals, as well as tribes and other entities in the Chugach region, said Cunningham.
Other research
Hank Stattscewich – Researcher from the College of Fisheries and Ocean Sciences of the University of Alaska Fairbanks – also presented in a study that he and seven others were conducted, which involved refining an active acoustic sonar system to acquire, treat and transmit data products. Autonomous underwater vehicles (gliders), armed with newly developed sensors, provide an alternative approach to survey ships to monitor ecosystems requiring environmental and biological data, Statscewich said during the symposium.
One of these deployments included a Shadowgraph submarine camera system mounted on a glider that provided high resolution images of the zooplankton encountered. Another, in the bay of resurrection, has almost roomed acoustic and optical data flows, according to their project summary.
Gary Shigenaka of the Office of the Response and Restoration of the Noaa spoke of a study of nine years on aquatic animals that live in the sediments at the bottom of the body of water. The researchers studied animals to determine the impacts of high pressure hydraulic techniques and heated water used in cleaning in the event of an exxon valdez oil disaster. His research team has found no significant difference in the impact on these aquatic animals between the conspiracies washed and not washed after a year – and the diversity measures of the species recovered by the third year after treatment, a- he said. This work has practical implications for the response of spills, the evaluation of damage and catering, concluded this team.
A team from the University of British Columbia led by the postdoctoral researcher Szymon Surma reported on the pelagic phase of the life cycles of the Pacific. The ecological interactions between salmon – as well as between salmon, predators, prey and competitors – in the open peaceful ocean remain the subject of intensive research, notes in its summary.
Andrew Seltz of the University of Alaska Fairbanks addressed participants in AMSS on predation on late quinnat salmon. His abstract notes that currently a petition is being examined to list the salmon from the Gulf of Alaska Chinook. Several factors probably stimulate these decreases and recent research has highlighted the potential importance to mortality at an advanced stage, said Seitz.
