Tiny particles bubbling up from the tops of melting sea ice into the Arctic sky may be a key, understudied element of cloud formation in that climate-sensitive region. Researchers from Colorado State University have published findings in Geophysical Research Letters that highlight how these airborne “ice-nucleating particles” from biological sources, such as bacteria, provide a platform […]
What do walrus monitoring, the Tracy Arm tsunami and salmon bycatch have in common? All of them are important topics for audiences in Alaska’s coastal communities. Which is why each has been the focus of a recent presentation at one of Alaska Sea Grant’s three public lecture series: Strait Science Series, the Petersburg Science […]
Arctic sea ice has declined by more than 42% since 1979, when regular satellite monitoring began. As the ice grows thinner and recedes, more water is exposed to sunlight. Ice reflects sunlight but dark water absorbs it, advancing warming and accelerating ice loss. Climate models indicate that the Arctic will see ice-free summers within the coming decades, and […]
