Results can help provide warning of red tide conditions in Florida’s coastal regions.
Seashells and lobster claws are hard to break, but chalk is soft enough to draw on sidewalks. Though all three are made of calcium carbonate crystals, the hard materials include clumps of soft biological matter that make them much stronger. A study today in Nature Communications reveals how soft clumps get into crystals and endow them with remarkable strength.
The Galápagos Islands have long offered researchers a natural laboratory in which to study unique volcanic features and a diverse population of native plants and animals.
Researchers from the Great Lakes Center at SUNY Buffalo State join scientists from 39 institutions as coauthors and advocates for international cooperation in furthering studies of freshwater mussels.

A 15 million year-old fossil sperm whale specimen from California belongs to a new genus, according to a study published December 9, 2015 in the open-access journal PLOS ONE by Alexandra Boersma and Nicholas Pyenson from the Smithsonian's National Museum of Natural History.
For years, many scientists thought we had a secret weapon to protect coral reefs from nutrients flushed into the seas by human activity. Experiments suggested that herbivores such as fish, urchins and sea turtles could keep corals and their ecosystems healthy by eating up extra algae that grew in the presence of these nutrients. But a new University of Florida study sheds doubt on that idea, underscoring the importance of sustainable growth in coastal areas.
By examining rocks at the bottom of ancient oceans, an international group of researchers have revealed that arsenic concentrations in the oceans have varied greatly over time. But also that in the very early oceans, arsenic co-varied with the rise of atmospheric oxygen and coincided with the coming and going of global glaciations. The study was recently published in the Nature Group Journal, Scientific Reports.
A dolphin’s echolocation beam was directed at a submerged man and the echo captured by a hydrophone system. The echo signal was sent to a sound imaging laboratory who created the first ever ‘what-the-dolphin-saw’ image of the submerged man, by using a cymatic-holographic imaging technique.
The GCOOS-RA today released a new plan that will help protect humans and marine life from the negative impacts caused by harmful algal blooms, or HABs.
Current El Niño conditions in the Pacific Ocean have created high water temperatures that are seriously damaging coral reefs, including those on Christmas Island, which may be the epicenter for what could become a global coral bleaching event.
A microscopic marine alga is thriving in the North Atlantic to an extent that defies scientific predictions, suggesting swift environmental change as a result of increased carbon dioxide in the ocean.
Simply oscillating its fins is all a flounder, a flat fish, needs to do to resuspend sand and quickly disappear beneath it to hide. By discovering the physics at play, researchers in France are hoping to provide a new flounder-inspired solution to a common technological challenge: the resuspension of granular material within a fluid. They'll discuss their findings at the American Physical Society's 2015 DFD Meeting.
Management of the world’s marine habitats needs to look beyond only Marine Protected Areas and put achieving ecosystem resilience at the top of the agenda, according to research by an international group of scientists led by Dr Richard Unsworth at Swansea University.
Fish have a remarkable way to hide from their predators using camouflage techniques. A new discovery shows that fish scales have evolved to not only reflect light, but to also scramble polarization. Scientists identified the tissue structure that fish evolved to do this, which could be an analog to develop new materials to help hide objects in the water.
Meet the furry faces of Florida’s watershed ecosystems in the special exhibit “Otters & Their Waters,” opening in early 2016 at Mote Aquarium in Sarasota, Fla.
A year ago, researchers discovered that fat helps coral survive heat stress over the short term—and now it seems that fat helps coral survive over the long term, too. The study offers important clues as to which coral species are most likely to withstand repeated bouts of heat stress, called “bleaching,” as climate change warms world oceans.
The sensitivity of marine communities to ocean warming rather than rising ocean temperatures will have strong short-term impacts on biodiversity changes associated with global warming, according to new research.
Ocean acidification may well be helping invasive species of algae, jellyfish, crabs and shellfish to move to new areas of the planet with damaging consequences, according to the findings of a new report.
How do the people putting sensor data to work judge the accuracy and reliability of the information they’re using? A new National Science Foundation (NSF)-funded project will develop the tools and the social and technical infrastructure to gather this metadata.
Charles H. Greene, professor of Earth and Atmospheric sciences in the College of Agriculture and Life Science at Cornell University and a fellow at the Atkinson Center for a Sustainable Future, says a rapidly changing climate will dramatically change the living marine resources and maritime traditions of seacoast communities, like those of New England and must be accounted for by those responsible for managing the nation’s marine living resources.
One way to monitor impacts to the ecosystem is by observing the changes in occurrence or distribution of sea birds and marine mammals. So a team of researchers is “eavesdropping” on marine mammals within the Arctic to monitor their presence year-round. Kathleen Stafford, oceanographer for the Applied Physics Lab at the University of Washington, will describe their work and the passive acoustic monitoring techniques involved at ASA’s Fall 2015 Meeting.
For centuries, cod were the backbone of New England’s fisheries and a key species in the Gulf of Maine ecosystem. Today, cod stocks are on the verge of collapse, hovering at 3-4% of sustainable levels. Even cuts to the fishery have failed to slow this rapid decline, surprising both fishermen and fisheries managers.
A new study in Ecology shows that Alaskan Dolly Varden trout, once they reach about 12 inches in length, can retire permanently from going to sea. They rely on digestive organs that can massively expand and contract and a unique relationship with sockeye salmon.
Recent research on the electric eel by Vanderbilt University biologist Ken Catania has revealed that it is not the primitive creature it has been portrayed. Instead, it has a sophisticated control of the electrical fields it generates that makes it one of the most remarkable predators in the animal kingdom.
Seals are not threatening commercial fishing stocks in Irish waters, with the possible exception of wild Atlantic salmon, according to new research led by Queen’s University Belfast, Northern Ireland, UK.
In the past, whales, giant land mammals, and other animals played a vital role in keeping the planet fertile by transporting nutrients via their feces. However, massive declines and extinctions of many of these animals has deeply damaged this planetary nutrient recycling system, threatening fisheries and ecosystems on land, a team of scientists reports.
According to a University of British Columbia study, only four percent of the ocean lies within marine protected areas. Their research was published in the journal Oryx.
In May 2007, hundreds of freshwater drum — also known as sheepshead — turned up dead in Lake Winnebago and nearby Little Lake Butte des Morts, both inland lakes near Oshkosh, Wisconsin. The fish were splotched with red and their eyes were swollen and bulging. The Wisconsin Department of Natural Resources (DNR) launched a quick response and, working with the Wisconsin Veterinary Diagnostic Laboratory (WVDL), quickly learned that a deadly virus was responsible: viral hemorrhagic septicemia virus, or VHSv.
The term “rational use,” as applied to fishing rights in Antarctic waters, has been misused by certain countries, an analysis by a team of researchers has concluded.
New research from UAB’s Department of Biology shows how one species can fully support the development of another species in a sustainable system.
Tourists in San Francisco witnessed a Great White Shark feeding on a seal in the bay while waiting to depart on the Alcatraz Ferry. A camera atop the ferry captured the attack in full.
Thanks to Yao's campaign with WildAid, support for a shark fin soup ban has skyrocketed in China.
The location of bubble plumes off the Pacific Northwest coast supports the idea that gradual ocean warming at about a third of a mile depth may be releasing frozen methane in the seafloor, causing it to release bubbles from the seafloor.
