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.
Antarctic bottom water (AABW) covers more than two-thirds of the global ocean bottom, and its formation has recently decreased. However, its long-term variability has not been well understood.
Curtin University researchers believe rising sea temperatures are to blame for the plummeting number of invertebrates such as molluscs and sea urchins at Rottnest Island off Western Australia, with some species having declined by up to 90 per cent between 2007 and 2021.
The project will host 125 field trips, which will educate as many as 3,125 socially disadvantaged middle and high school students about Florida’s natural resources and the importance of conserving them.
Life began on earth more than 3.5 billion years ago, but the history of humans and other vertebrates accounts for only a fraction of this timescale.
A research team including a scientist from Oregon State University has provided the first experimental evidence that a species of endangered sea star protects kelp forests along North America’s Pacific Coast by preying on substantial numbers of kelp-eating urchins.
The meal of choice for the Caribbean cleaner fish, the sharknose goby, is a platter of parasites, dead tissue, scales and mucus picked off the bodies of other fishes.
When scientists disabled a single regulatory gene in a species of sea anemone, a stinging cell that shoots a venomous miniature harpoon for hunting and self-defense shifted to shoot a sticky thread that entangles prey instead, according to a new study.
Today, a team of scientists and engineers from Woods Hole Oceanographic Institution (WHOI) left Charleston, SC aboard the R/V Neil Armstrong to begin test deployments in preparation for the installation of an Ocean Observatories Initiative (OOI) ocean observing system in its new location in the southern Mid-Atlantic Bight (MAB).
When the Covid-19 pandemic hit in 2020 with associated travel restrictions, Matthew Long thought his students could shift their overseas research projects to instead study the seagrass meadow ecosystem in Waquoit Bay. It’s a shallow, micro-tidal estuary on the south side of Cape Cod in Massachusetts, near the Woods Hole Oceanographic Institution (WHOI) where Long is an associate scientist in the Marine Chemistry and Geochemistry Department.
Several years in the making, Wahoo Bay will serve partly as an educational marine park as well as an initiative to restore the natural habitat. Using AI and sensors, FAU engineers and students will deploy automated weather monitoring stations, underwater cameras, vehicles, acoustic and water quality monitoring sensors in Wahoo Bay, a "living" laboratory that provides an immersive experience for visitors while raising awareness of keeping oceans and coral reef systems healthy.
A team of international researchers has shown for the first time how 18 meltwater lakes in Greenland collapse during winter which cause the edges of the ice to flow faster. The new knowledge is essential for understanding how climate change influences the flow of ice masses in the Arctic
A new study demonstrates the important role of a common group of marine calcifying phytoplankton (coccolithophores) in the regulation of carbon dioxide (CO2) concentrations in the atmosphere.
Marine biologists discovered that reintroducing sunflower sea stars could help restore kelp forests.
Not all Chinook salmon are created equal, and this has a major impact on the energetics for southern resident killer whales.
World first research from CSIRO and the University of South Australia shows that the feathers of seabirds such as the Wandering Albatross can provide clues about their long-distance foraging, which could help protect these species from further decline.
Today, species richness peaks in equatorial regions but until now there has been no clear explanation for this.
The tropical oceans are home to the most diverse plankton populations on Earth, where they form the base of marine food chains.
Seabed mining could soon begin in the deep ocean – but the potential impact on animals including whales is unknown, researchers have warned.
Decisions are difficult. Humans often find themselves deliberating between multiple conflicting alternatives, or frustratingly fixated upon a single option.
Just how hard should natural resource managers fight invasive species after they establish? A new University of Illinois study suggests some invaders – even highly successful ones – can die off naturally, leaving native communities to rebound with minimal management effort.
There is currently less sea ice in the Antarctic than at any time in the forty years since the beginning of satellite observation: in early February 2023, only 2.20 million square kilometres of the Southern Ocean were covered with sea ice.
A research team led by Specially Appointed Professor Masanori Kohda from the Graduate School of Science at the Osaka Metropolitan University has demonstrated that fish think “it’s me” when they see themselves in a picture, for the first time in animals.
Thanks to researchers at NSU’s Guy Harvey Research Institute (GHRI) who designed a novel electronic tag package incorporating high-tech sensors and a video camera, we now have for the first time, a detailed view of exactly how sailfish behave and hunt once they are on their own and out of view of the surface.
Forget Punxsutawney Phil and his shadow - Nova Southeastern University has Captain the Sea Turtle and her Shell - and she's predicting the future!
The team's new methodology offers hope for better coral connectivity monitoring and protection in the future.
Difference in body size (or sexual dimorphism) between males and females is common across the animal kingdom.
Protected marine areas are one of the essential tools for the conservation of natural resources affected by human impact —mainly fishing—, but, are they enough to recover the functioning of these systems?
Ongoing climate change driven by greenhouse gas emissions is often discussed in terms of global average warming. For example, the landmark Paris Agreement seeks to limit global warming to 1.5 ⁰C, relative to pre-industrial levels. However, the extent of future warming will not be the same throughout the planet. One of the clearest regional differences in climate change is the faster warming over land than sea. This “terrestrial amplification” of future warming has real-world implications for understanding and dealing with climate change.
Changes in river systems, overfishing and the appearance of new, invasive species can lead to a drastic decline in the number of native fish inhabiting aquatic ecosystems.
Ten years ago, Dr Virginia Andrews-Goff was riding the bowsprit of a six-metre boat, as a 30-metre, 120-tonne Antarctic blue whale surfaced alongside.

Humans continue to amplify global warming by emitting billions of tons of carbon dioxide into the atmosphere each year.
Human actions are changing the environment at an unprecedented rate. Plant and animal populations must try to keep up with these human-accelerated changes, often by trying to rapidly evolve tolerance to changing conditions.
While microplastics have received significant attention in recent years for their negative environmental impacts, a new study from Oregon State University scientists found microfibers from synthetic materials as well as cotton impacted the behavior and growth of water organisms.
Ancient fossils have shed new light on a type of sea worm linking it to the time of an evolutionary explosion that gave rise to modern animal life.
Researchers have successfully split seawater without pre-treatment to produce green hydrogen. The international team was led by the University of Adelaide’s Professor Shizhang Qiao and Associate Professor Yao Zheng from the School of Chemical Engineering. “We have split natural seawater into oxygen and hydrogen with nearly 100 per cent efficiency, to produce green hydrogen by electrolysis, using a non-precious and cheap catalyst in a commercial electrolyser,” said Professor Qiao.
