Faster decomposition in warmer waters could reduce kelp contributions to deep sea carbon stores.
Citizen scientists spent thousands of hours observing trash on beaches in Washington and Oregon. Their surveys show that certain beaches, and certain areas of a single beach, are “sticky zones” that accumulate litter. Finding patterns for where litter lands could help to better prevent and remove trash in the marine environment.
Underwater robots are being widely used as tools in a variety of marine tasks. The RobDact is one such bionic underwater vehicle, inspired by a fish called Dactylopteridae known for its enlarged pectoral fins.
Near-real-time fish tracking using a new acoustic receiver developed by PNNL can support enhanced fish passage through hydropower dams.
The human-occupied submersible Alvin is ready to return to scientific research at its newly certified maximum depth of 6500 meters (4 miles). That’s the conclusion of a team of scientists who have spent the past three weeks taking the iconic sub through its paces at locations at the Puerto Rico Trench and Mid-Cayman Rise, testing its scientific and engineering systems to ensure they are capable of supporting the demands of deep-sea sample and data collection.
Using sophisticated electronic tags, scientists have assembled a large biologging dataset to garner comparative insights on how sharks, rays, and skates – also known as “elasmobranchs” – use the ocean depths.
Research published by Woods Hole Oceanographic Institution (WHOI) scientists today in Frontiers in Marine Science confirmed their previous observations that rising temperatures increase the sound of snapping shrimp, a tiny crustacean found in temperate and tropical coastal marine environments around the world.
A newly-discovered walking shark that breaks all of the rules for survival is the focus of a first-of-its-kind study that examined differences in walking and swimming in neonate (newly-hatched) and juvenile walking sharks. Despite dissimilarities in body shapes – neonates have bulging bellies and juveniles are slender – the three aquatic gaits they use (slow-to-medium walking, fast-walking and swimming) did not differ. Kinematics between neonate and juvenile epaulette sharks did not alter during development.
A previously overlooked factor — the position of continents — helps fill Earth’s oceans with life-supporting oxygen. Continental movement could ultimately have the opposite effect, killing most deep ocean creatures.
The reconstructed megadolon (Otodus megalodon) was 16 meters long and weighed over 61 tons. It was estimated that it could swim at around 1.4 meters per second, require over 98,000 kilo calories every day and have stomach volume of almost 10,000 liters.

The extent of plastic pollution remains largely hidden from view in the form of microplastics (MPs): plastic particles with diameters less than 5 mm.
Researchers have identified a new species of Bathonymus, the famed genera of deep-sea isopods whose viral internet fame has made them the most famous aquatic crustaceans since Sebastian of The Little Mermaid.
Phytoplankton is the foundation of all life on the planet. Understanding how these photosynthetic organisms react to their ocean environment is important to understanding the rest of the food web.
British Columbia’s ocean contributed almost $5 billion to provincial gross domestic product in 2015, a sum that is likely an underestimate, a new UBC study has found.
From fecal bacteria to blue-green algae to red tides, Southwest Florida’s water quality has declined as its population has increased. Multiple lines of evidence from a multi-year microbial source tracking study points to septic systems as a contributing source for this decline. The study is one of few to connect downstream harmful algal blooms with nutrient loading from upstream septic systems. These water quality issues are caused by aging septic systems installed in high densities in areas with shallow water tables. Septic systems may actually be sitting in groundwater during certain times of the year, which means that they cannot function properly.
Paul Salem, a leader in private equity and non-profit board service, has been named Woods Hole Oceanographic Institution’s new Chair of the Board of Trustees. Salem will transition into the role officially on January 1, 2023, taking over for David Scully, who has served as the Board Chair for the past seven years.
Rapid 20th century warming in the Gulf of Maine has reversed long-term cooling that occurred there during the previous 900 years, according to new research that combines an examination of shells from long-lived ocean quahogs and climate model simulations.
A study published recently in the prestigious journal Nature Ecology and Evolution has unveiled some of the key processes in marine microbial evolution.
A new study analyses human impacts on biodiversity and ecosystem functioning in 72 lakes distributed across four large neotropical wetlands of Brazil – Amazon, Araguaia, Pantanal and Paraná. The research spans a 3.7million km gradient of human activities in Brazil.
Tropical coastal ecosystems are among the most biodiverse areas on Earth. And they’re also on the front lines of effects caused by human activity.
The North Pacific Blob, was the largest and longest-lasting marine heatwave on record. A new study using data collected by elephant seals reveals that in addition to the well documented surface warming, deeper warm-water anomalies associated with the Blob were much more extensive than previously reported.
Research published in Global and Planetary Change examines the trends and projected frequency, intensity and duration of marine heatwaves (MHWs).
Weddell seals, which are excellent divers, provide so much iron to their pups during lactation, that the mothers dramatically limit their own diving and underwater foraging capabilities.
For the generations who grew up watching Finding Nemo, it might not come as a surprise that the North American West Coast has its own version of the underwater ocean highway – the California Current marine ecosystem (CCME).
Are sea animals involved in the reproductive cycle of algae, like pollinating insects on dry land? Dispersal of the male gametes, or spermatia, of red algae generally relies on water movement, and up until now, scientists did not recognize the role played by animals.
For some species conquering new territory, it might be better to live fast and die young.
UB study warns about the ecological impact of native species in waters that do not correspond to them.
Trilobites- extinct marine arthropods that roamed the world’s oceans from about 520 million years ago until they went extinct 250 million years ago, at the end of the Permian period - may have grown in a similar fashion and reached ages that match those of extant crustaceans, a new study has found.
Earlier today (July 21, 2022) the human-occupied submersible Alvin made history when it successfully reached a depth of 6,453 meters (nearly 4 miles) in the Puerto Rico Trench, north of San Juan, P.R. This is the deepest dive ever in the 58-year history of the storied submersible.
Higher water temperatures induce specific chemical tags at targeted locations on the DNA of embryonic zebrafish.

The latest research news in Climate Science on Newswise.
More of the world’s coastal glaciers are melting faster than ever, but exactly what’s triggering the large-scale retreat has been difficult to pin down because of natural fluctuations in the glaciers’ surroundings. Now, researchers have developed a methodology that they think cracks the code to why coastal glaciers are retreating, and in turn, how much can be attributed to human-caused climate change.
