With over 30,000 km of shoreline, Alaska is home to some of the world’s richest fisheries. In Southeast Alaska, like much of the state, coastal communities depend on commercial and subsistence fisheries for their livelihood. With such a vast and varied environment, obtaining long-term oceanographic data is challenging, limiting understanding of patterns and the ability […]
A new University of Alaska Fairbanks–led study has found that razor clams accelerate their shell development when exposed to more acidic ocean conditions, but that those young shells are built with more fragile substances. How shellfish react to changing marine conditions is a growing concern as climate change gradually shifts ocean chemistry. The threat of […]
The first use of a novel method of analyzing Mars’ gravitational force supports the idea that the planet once had an extensive northern ocean. In doing so, the method defines the scope of what scientists refer to as the northern Martian paleo-ocean in more detail. The work was published in July in the journal Icarus, which is affiliated with […]
New research by an international team of scientists explains what’s behind a stalled trend in Arctic Ocean sea ice loss since 2007. The findings indicate that stronger declines in sea ice will occur when an atmospheric feature known as the Arctic dipole reverses itself in its recurring cycle. The many environmental responses to the Arctic […]
