The ability to model and predict the size of ocean waves is important for the fishing industry from both logistic and economic perspectives. Essentially, the bigger the waves, the more expensive the fish.
A study published in Nature Communications by an international team of climate scientists uncovers the physical mechanisms that can cause uneven future warming in the Indian Ocean and corresponding shifts in monsoon precipitation.
Lehigh Engineering researcher Arup SenGupta has developed a novel way to capture carbon dioxide from the air and store it in the “infinite sink” of the ocean.
Cape Cod’s salt marshes are as iconic as they are important. These beautiful, low-lying wetlands are some of the most biologically productive ecosystems on Earth.
The Indo-West Pacific is the largest, most biodiverse marine ecosystem on Earth, and many of the species it supports have comparably wide ranges. Writing in “The Origin of Species,” Charles Darwin noted that “… many fish range from the Pacific into the Indian Ocean, and many shells are common to the eastern islands of the Pacific and the eastern shores of Africa, on almost exactly opposite meridians of latitude.”
A research group including Professors Mitsumasa Koyanagi and Akihisa Terakita of the Osaka Metropolitan University Graduate School of Science has investigated both the genetic information and structure of the photoreceptor rhodopsin, responsible for detecting dim light, of whale sharks to investigate how they can see in the dim light at extreme depths.
Climate change. Overfishing. Seabed floor mining. These are some of the epic challenges that would be addressed by a historic United Nations treaty protecting ocean biodiversity that gained backing in early March when a significant majority of nations agreed on language supporting it. Covering the “high seas,” the enormous belt of brine spanning nearly half of the globe, the U.
Scientists aboard a U.S. research vessel in the tropical Atlantic are taking advantage of the ship’s long-planned path through the Great Atlantic Sargassum Belt to take some of the first samples from a massive, ongoing bloom. Photos and video from the ship show the algae mats on the surface of the eastern Atlantic in the belt that extends from west Africa to the Gulf of Mexico.
Diagnostic imaging such as X-rays, MRIs, and CT scans are important tools in monitoring the health of humans and animals. But for researchers in the field, it is difficult to administer these common tests on wild populations.
A research group from Nagoya University in central Japan has discovered three new species of bioluminescent polycirrus worms from different parts of Japan.
New research reveals how salt marshes along the U.S. East Coast have responded to accelerating sea level rise by building elevation more quickly to keep pace with the sea over the last century.
For wild animals, false alarms are the most widespread form of misinformation. Deploying camera observatories in a coral reef in French Polynesia, researchers have shown that even in the absence of predators, escape events occur frequently in natural groups of foraging fish but rarely spread to more than a few individuals. These animals form dynamic information exchange networks and adjust their responsiveness to visual cues based on the recent history of sensory inputs from neighbors.
Fish can adjust their sensitivity to the actions of others – such as fleeing due to a false alarm – to reduce the risk of responding to misinformation, according to a new study. Other animals, including humans, may also have these decision-making mechanisms.
In a paper published today in the journal Environmental Research Letters, an international research team composed of scientists affiliated with more than a dozen institutions, including the California Academy of Sciences, propose a first-of-its-kind framework for governments around the world to evaluate their preparedness for—and guide future policies to address—ocean acidification, among the most dire threats to marine ecosystems.
A team of scientists led by a Brown University researcher has developed a new method for monitoring when deep sea methane deposits convert to gas and rise toward the seafloor in amounts that were previously too small to detect.
See how CSU faculty and students are studying ways to capture stormwater and strengthen drought resilience.
The diet quality of fish across large parts of the world’s oceans could decline by up to 10 per cent as climate change impacts an integral part of marine food chains, a major study has found.
The first study into the biological response of the upper ocean in the wake of South Pacific cyclones could help predict the impact of warming ocean temperatures, New Zealand researchers believe.

Noise from human activities is harming ocean invertebrates and ecosystems, new research shows.
A new study is providing an unprecedented examination of oxygen loss on coral reefs around the globe under ocean warming. Led by researchers at UC San Diego’s Scripps Institution of Oceanography and a large team of national and international colleagues, the study captures the current state of hypoxia—or low oxygen levels—at 32 different sites, and reveals that hypoxia is already pervasive on many reefs.
A new study published today in the journal Nature brings scientists one step closer to knowing how or when massive quantities of water arrived on earth.
Researchers at Cummings School of Veterinary Medicine at Tufts University found that an outbreak of highly pathogenic avian influenza (HPAI) was associated with the deaths of more than 330 New England harbor and gray seals along the North Atlantic coast in June and July 2022, and the outbreak was connected to a wave of avian influenza in birds in the region.
A Secchi disk – historically called a “dinner plate” by sailors – is used in the open ocean to measure concentrations of microscopic algae called phytoplankton.
This support expands FAU Harbor Branch’s extensive aquaculture and food security program focused on replenishing queen conch populations throughout the Caribbean. It also enables development of a conceptual master plan for a 25-acre innovation hub on Grand Bahama for researchers working to solve issues of island sustainability.
Government and political institutions should do more to make citizens feel empowered within marine environment decisions and give them the right to participate, new research shows.
Researchers show that mesophotic coral reefs function much differently than their shallower counterparts and are unlikely to offer a refuge for shallow water fishes trying to escape climate-change driven warming on the ocean’s surface.
Nominations are now open for the GCOOS Board of Directors, who help set policy for the Gulf of Mexico's certified ocean observing entity.
In the Pacific Northwest and British Columbia, southern resident orcas have experienced no net population growth since the 1970s. But northern resident orcas, with a similar diet and territory, have grown steadily. A new study may help explain why: The two populations differ in how they hunt for salmon, their primary and preferred food source.
An analysis extending from southern Portugal to northern Norway highlights the importance of temperature in determining where fish species are found.
A team of polymer chemists in Florida State University’s Department of Chemistry and Biochemistry is developing a new antifouling coating to keep these sea creatures at bay. The work is funded through a new $510,000 grant from the U.S. Office of Naval Research.
As millions of tonnes a year of microplastic waste mounts in marine environments, Flinders University scientists warn the ramifications to wildlife, food webs and human health are still little understood.
A global dataset of ocean plastic pollution between 1979 and 2019 reveals a rapid and unprecedented increase in ocean plastics since 2005, according to a study published March 8, 2023 in the open-access journal PLOS ONE by Marcus Eriksen from The 5 Gyres Institute, USA, and colleagues.
In a newly published paper in the journal Papers in Palaeontology, University of Illinois Chicago’s Roy Plotnick and colleagues report that fossils long-interpreted as jellyfish were anemones. To do so, they simply turned the ancient animals upside down.
It’s not just humans who enjoy eating shellfish, so do marine rays. They like to “crunch” on clams, which can sometimes take a big bite out of clammers’ profits. Using aerial and underwater videos, researchers assessed the ability of the whitespotted eagle ray to interact with clams housed within a variety anti-predator materials. Whitespotted eagle rays have strong jaws, plate-like teeth and nimble pectoral fins, which make them formidable and highly maneuverable predators of clams.
A Rutgers-led team of scientists studying virus-host interactions of a globally abundant, armor-plated marine algae, Emiliania huxleyi, has found that the circular, chalk plates the algae produce can act as catalysts for viral infection, which has vast consequences for trillions of microscopic oceanic creatures and the global carbon cycle.
The 18-foot-long structures, including fascinating honeycomb-shaped tubes, are part of an effort by University of Miami researchers and scientists to help restore damaged coral reefs and protect coastal environments.
The oceans help to limit global warming by soaking up carbon dioxide emissions. But scientists have discovered that intense warming in the future could lessen that ability, leading to even more severe warming.
Dolphins and other toothed whales are large brained top predators that captivate our imagination; they are extremely social, they cooperate, and can hunt prey down to 2 km deep in complete darkness with echolocation.
With the help of an underwater robot, known as Icefin, a U.S.-New Zealand research team has obtained an unprecedented look inside a crevasse at Kamb Ice Stream — revealing more than a century of geological processes beneath the Antarctic ice.
In a new study, researchers used new technologies to remotely document, for the first time in the wild, the location and timing of shark birth. Named the Birth-Alert-Tag (BAT), this new satellite tag remained inside the uterus, along with the developing shark pups, until the mother shark gave birth and expelled the newborn pups, along with the BAT, into the surrounding water. The BAT then floated to the surface and transmitted to satellites the location of where the shark birth took place. The first of its kind, the BATs were successfully deployed in a tiger shark and scalloped hammerhead shark, documenting the location birth.
The Red Tide Respiratory Forecast — www.RedTideForecast.com — is a beach-level risk forecast activated during red tide conditions that tells beachgoers what red tide impacts are expected to be at individual beaches at different times of the day. The Forecast is also available in Spanish at www.PronosticoMareaRoja.com.
A new study of New Zealand blue whales’ vocalizations indicates the whales are present year-round in the South Taranaki Bight and their behavior is influenced by environmental conditions in the region.
In 2011, scientists recorded a previously unknown feeding strategy in whales around the world. Now, researchers in Australia think they may have found evidence of this behaviour being described in ancient accounts of sea creatures, recorded more than 2,000 years ago.
By returning to spawn in the Sacramento River at different ages, Chinook salmon lessen the potential impact of a bad year and increase the stability of their population in the face of climate variability, according to a new study by scientists at UC Santa Cruz and NOAA Fisheries.
Cartilaginous fish have changed much more in the course of their evolutionary history than previously believed. Evidence for this thesis has been provided by new fossils of a ray-like shark, Protospinax annectans, which demonstrate that sharks were already highly evolved in the Late Jurassic. This is the result of a recent study by an international research group led by palaeobiologist Patrick L. Jambura from the Department of Palaeontology at the University of Vienna, which was recently published in the journal Diversity.
