A Boston College-led study suggests that enhanced mid-ocean-ridge volcanism may have released hydrothermal iron that fertilized plankton in the eastern equatorial Pacific during ice-age transitions. The work reveals a hidden connection among sea level, deep-sea volcanism, ocean productivity, carbon storage, and climate.

Rhodoliths may look like small rocks on the seafloor, but they're actually living algae that create habitats for marine life and contribute to long-term carbon storage.  A new study found that the deeper ‘low-light’ waters off Japan's Tanegashima Island harbor a surprisingly distinct and diverse community of these ‘living pink rocks,’ including four species completely new to science. Researchers identified at least 12 species in a small patch of seafloor 35–38 meters deep, but only three were also found in nearby shallow waters, suggesting the deeper habitat is not simply a continuation of the one near the surface.

Lesser black-backed gulls from the colony at the Dutch island Neeltje Jans appear to avoid the wind farm off the Zeeland coast, with the exception of some males. NIOZ ecologist Rosemarie Kentie and her colleagues suspected the gulls were attracted by fishing boats outside the windfarm, and their bycatch thrown overboard. This turned out not to be the case: even during weekends, when there is little fishing, the birds rarely visit the wind farm. They published their findings in the Journal of Animal Ecology. “Why the gulls still avoid the wind farm fascinates me immensely.”

The loss of biological diversity is one of the greatest challenges of our time. At the fourth World Biodiversity Forum in Davos, leading biodiversity researchers are joining participants from politics, business, civil society and the arts to develop a common approach for biodiversity protection.

The University of New Hampshire (UNH) will lead a new national effort to grow and strengthen America’s seafood supply through aquaculture research. After a highly competitive application process, UNH, which has a long history of innovation in the farming of aquatic species, was selected to oversee the first-of-its-kind NOAA Cooperative Institute Fostering Aquaculture Research and Markets (CIFARM). With approximately $13.5 million in initial funding, CIFARM will support research and partnerships that will make it safer, more environmentally friendly and cost-effective to produce seafood domestically. 

Marine wildlife trafficking is big business, raking in billions of dollars every year and threatening species’ survival and the health of ecosystems. But trafficked sea creatures are often concealed in ordinary travelers’ luggage or packages, which makes it hard to spot and seize illicit shipments. Now scientists have used a neural network, a form of AI, to teach an algorithm to spot three commonly trafficked products — shark fins, sea cucumbers, and dried seahorses — in CT scans of bags like those taken at airports. The algorithm, which had a 92% success rate in testing, could help detect marine wildlife trafficking at scale and stop the trade in progress.

A three-year study has cracked open the hidden biology behind coral reproduction, revealing hormone cycles that echo those of humans and other animals, and a new way to detect reef distress before it's too late.
