It’s been a busy couple of months for members of the Alaska Marine Mammal Stranding Network, including Alaska Sea Grant’s Gay Sheffield, as they respond to multiple reports of dead ice seals along the coast of the Bering and Chukchi Seas. NOAA Fisheries reported in mid-June that at least 60 seals have recently washed up…
Read MoreSoutheast Alaska tribal council develops climate change plan
Climate change in Alaska’s high Arctic often captures headlines. Images of vanishing sea ice, dead seabirds, beached marine mammals, melting permafrost and houses tumbling into the ocean are common. Less media attention is directed to Southeast Alaska, an archipelago of hundreds of islands around a thin strip of mainland, blanketed by coastal temperate rainforest. But…

The U.S. Fish and Wildlife Service has honored Alaska Sea Grant’s Gay Sheffield and Brandon Ahmasuk of Kawerak, Inc. for leading a coordinated response to seabird mortality events across the Bering and Chukchi region. Since 2013, Sheffield, an associate professor at the University of Alaska Fairbanks, College of Fisheries and Ocean Sciences, and Ahmasuk have…
Read MoreScientists study fate of salmon in a changing Alaska landscape
From coastal shores to inland mountains, salmon are part of the fabric of Alaska. Salmon have been harvested by Alaska Natives for thousands of years and remain a critical part of the state’s commercial, recreational and subsistence fisheries. As anadromous fish, salmon spend the first months to years of their lives in freshwater before migrating…
Read MoreCarbon dioxide sample from Utqiaġvik provides wake-up call on climate
How does the buildup of carbon dioxide in the atmosphere measured at Hawai‘i’s Mauna Loa volcano over the last six decades compare with the air above Alaska? During a recent spring trip to Utqiaġvik, I had a chance to find out by visiting the farthest-north atmospheric observatory operated by the National Oceanic and Atmospheric Administration…
Read MoreLaying the foundation for resilient coastal communities
Average temperatures in Alaska have increased twice as fast as anywhere in the country over the last century. This warming—as much as 6 degrees in winter and three degrees in summer—is expected to continue along with the effects of disappearing sea ice, thawing of permafrost, changes in fish and wildlife patterns, extreme flooding and erosion.…
Read More“We have never been here before” — Gay Sheffield, on ecosystem-wide changes in the Bering Sea
The Bering Sea is undergoing massive changes that include the dramatic loss of sea ice last winter. As Alaska Sea Grant Marine Advisory agent Gay Sheffield notes in the interview below, “we have never been here before.” Sheffield spoke to the Associated Press at the American Geophysical Union conference this week in Washington, D.C., saying…

Read MoreScientists use app to engage citizens in ocean acidification study
Clam populations throughout Alaska have steadily declined for over 20 years, affecting subsistence, recreational and commercial harvesters. The exact causes of the decline are unknown. Suspected factors include habitat changes, environmental stressors, predation and, possibly, ocean acidification. Under the supervision of University of Alaska Fairbanks professor Amanda Kelley, PhD student Ashley Rossin is studying the…
