Scientists have long known that the ocean plays an essential role in capturing carbon from the atmosphere, but a new study from Woods Hole Oceanographic Institution (WHOI) shows that the efficiency of the ocean’s “biological carbon pump” has been drastically underestimated, with implications for future climate assessments.Read more
Climate change could threaten the survival and development of common whelk – a type of sea snail – in the mid-Atlantic region, according to a study led by scientists at Rutgers University–New Brunswick. The common, or waved, whelk (Buccinum undatum) is an important commercial species that has been harvested for decades in Europe and Canada for bait and human consumption. Its habitat within the mid-Atlantic region is one of the Earth’s fastest warming marine areas and annual fluctuations in the bottom temperature are among the most extreme on the planet due to unique oceanographic conditions.Read more
A nuclear war that cooled Earth could worsen the impact of ocean acidification on corals, clams, oysters and other marine life with shells or skeletons, according to the first study of its kind.Read more
If you want to know how climate change and hypoxia — the related loss of oxygen in the world’s oceans — affect fish species such as the economically important Baltic cod, all you have to do is ask the fish. Those cod, at least, will tell you that hypoxia is making them smaller, scrawnier and less valuable. A paper published today in the journal Biology Letters points to a link between hypoxia and fish well-being.
Fisheries acoustics have been studied for over 40 years to assess biomass and optimize aquaculture applications, and researchers in France have examined the phenomenon of how fish scatter acoustic waves in a dense school of fish contained in an open-sea cage. They developed an approach to help overcome issues encountered in aquaculture relating to the evaluation of the total biomass of dense schools of fish. They will discuss their work at the 178th ASA Meeting.Read more

Rising ocean temperatures have long been linked to negative impacts for marine life, but a Florida State University team has found that the long-term outlook for many marine species is much more complex — and possibly bleaker — than scientists previously believed.FSU doctoral student Jennifer McHenry, Assistant Professor of Geography Sarah Lester and collaborators with the National Oceanic and Atmospheric Administration (NOAA) investigated how marine species’ habitats are likely to be affected by multiple factors associated with climate change such as ocean temperature, salinity and sea surface levels.Read more
