Atlantic-origin water extension into the Pacific Arctic induced an anomalous biogeochemical event - Nature Communications The authors show that the appearance of anomalously low oxygen and acidified water on the Chukchi Plateau, a high-seas fishable area of the western Arctic Ocean, is associated with a change in basin-s...

The Chukchi Ecosystem Observatory (CEO) mooring that had been deployed in 2022, but had failed to re-surface in 2023 and 2024, has been recovered! It was brought on board successfully through the use of the ROV operated yesterday. It is expected that the data stored on the mooring will be recoverable.

#SKQ202515s has successfully recovered all of the moored sensors at the #Chukchi Ecosystem Observatory #CEO! 🙌

#SKQ202515s finished the the last major transect line for the Distributed Biological Observatory DBO4. 🙌

Seawater samples are collected from the profiling #CTD aboard the research vessel #Sikuliaq in the #Chukchi Sea. 🧪🌊🦑🐻‍❄️

Sea star collected in the Chukchi Sea during the Arctic Collaborative Cruise aboard the University of Alaska Fairbanks research vessel Sikuliaq. Samples are collected by Van Veen grab, and also a small scientific trawl at selected stations. The samples collected are identified, weighed, counted, and the benthic community can therefore be described and biomass per square meter estimated.

Benthic sampling helps establish how healthy the ecosystem is and how it is responding to changes such as how much sea ice is present each winter. 🧪🌊🦑

Sea Ice for Walrus Outlook A resource for Alaska Native subsistence hunters, coastal communities, and others interested in sea ice and walrus.

#AOOS partners with the Eskimo Walrus Commission, @uafairbanks.bsky.social, #NOAA #NWS, and the #Arctic Research Consortium to provide information for subsistence hunters in the #BeringSea and #Chukchi Sea. 🧪🌊🦑
