New science shows that overfishing is eroding the sustainability of tropical coral reef fisheries in East Africa, with small-scale fishers losing out on fisheries productivity as entire species disappear from their catch.
With state funding, Washington Sea Grant will work with the Washington Department of Fish and Wildlife and the Woods Hole Oceanographic Institution to shed light on a highly invasive species
At WHOI, Motta leads the Theoretical Chemistry and Isotope Biogeochemistry Lab. Her research focuses on advancing our fundamental understanding of chemistry inspired by marine processes that challenge our current chemical knowledge.
GCOOS — the ocean observing organization dedicated to America's Gulf — is celebrating its 20th anniversary throughout the year.
Until now, a global evaluation of ocean current energy with actual data was lacking. Using 30 years of NOAA's Global Drifter Program data, a study shows that ocean currents off Florida's East Coast and South Africa have exceptionally high-power densities, ideal for electricity generation. With densities over 2,500 watts per square meter, these regions are 2.5 times more energy-dense than “excellent” wind resources. Shallow waters further enhance their potential for ocean current turbines, unlike areas like Japan and South America, which have lower densities at similar depths.

Faster identification of fish sounds from acoustic recordings can improve research, conservation efforts
In JASA, researchers from Woods Hole Oceanographic Institution combine acoustic monitoring with a neural network to identify fish activity on coral reefs by sound. They trained the network to sort through the deluge of acoustic data automatically, analyzing audio recordings in real time. Their algorithm can match the accuracy of human experts in deciphering acoustical trends on a reef, but it can do so more than 25 times faster, and it could change the way ocean monitoring and research is conducted.
A new scientific study provides many new insights into the biology of the prehistoric gigantic shark, Megalodon or megatooth shark, which lived nearly worldwide 15-3.6 million years ago. Paleobiology professor Kenshu Shimada of DePaul University led the study along with 28 other shark, fossil, and vertebrate anatomy experts around the globe.
A study conducted by Cornell University and the Wildlife Conservation Society (WCS), both members of the Amazon Waters Alliance, reveals that small, abundant, and nutritious fish species in the Amazon can be a solution for both public health and biodiversity conservation.
Using drones, 17 distinct behaviors of narwhals were captured in the wild. Findings reveal complex behaviors of the Arctic’s iconic whale never seen before. This highly gregarious whale uses its tusk to investigate, manipulate and influence the behavior of a fish, the Arctic char. The study also provides the first evidence of play, specifically exploratory-object play, and the first reports of kleptoparasitism, a “food thief” situation, among narwhals and glaucous gulls.
Researchers call for regional and context-specific approaches to these extreme events
Tiny bits of plastic found in the ocean may be tied to a higher risk of disability for people who live in coastal areas with high levels, according to a preliminary study released today, February 25, 2025, that will be presented at the American Academy of Neurology’s 77th Annual Meeting taking place April 5–9, 2025, in San Diego and online. The study looked at disabilities affecting memory and thinking, mobility and a person’s ability to take care of oneself.
Experts from 12 countries in Latin America have together published the most comprehensive summary of conservation knowledge to date of the giant otter (Pteronura brasiliensis), including the identification of the most important riverine areas providing habitat for this aquatic icon of the Amazon.
Biologist Jérémy De Bonville has analyzed the ability of four fish species to acclimate to temperature variations in their marine habitats.
A new study introduces an innovative framework that harnesses satellite observations and machine learning models to quantify the direct impacts of typhoons on vegetation canopy structure and photosynthesis.
A Thai research team, part of the Royal Polar Research Project, has arrived at the Great Wall Station in Antarctica, uncovering significant ice melt compared to previous years—a stark indicator of climate change’s accelerating effects.
A new South African Whale Centre is planned to be constructed in the heart of Hermanus, whale capital of South Africa, which will house the Whale Unit of the University of Pretoria’s (UP’s) Mammal Research Institute (MRI).
Australian researchers are designing a global real-time monitoring system to help save the world’s coral reefs from further decline, primarily due to bleaching caused by global warming.
Dungeness crab, Pacific herring, and red abalone are among the marine species most vulnerable to the changing climate's effect on California's coastal waters, a new study led by UC Santa Cruz researchers finds.
