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.
Virginia Tech fluid dynamics research explores why some plankton can breach the air-water interface while others can't
The genetic and developmental innovations plants used to make the leap to land have been enduring secrets of nature. Now, an international team of researchers reveals that the aquatic algae from which terrestrial plant life first arose were genetically pre-adapted to form the symbiotic relationships with microorganisms that most land plants need to acquire nutrients from the soil.
A new report published Tuesday documents all of the fishes that live in the Salish Sea. In total, 253 fish species have been recorded, and that’s about 14 percent more than in the last count.
When the population of one of the Chesapeake Bay’s most famous residents, the blue crab, went into rapid decline due to overfishing, the Smithsonian stepped in to help. Scientists at the Smithsonian Environmental Research Center (SERC) have been tracking blue crabs throughout the Chesapeake Bay for decades to understand the impact fisheries have on crab populations. After the crabs are caught, scientists record their condition, size and sex; next, they are given a tag with a number unique to that animal and the phone number for the “Blue Crab Hotline.” The crab is then released back into the Bay.
A new report from the Gulf of Mexico Coastal Ocean Observing System Regional Association details the first 10 years of the nonprofit organization's work to improve access to ocean observing data that helps to protect and preserve the Gulf and its residents.
New research involving scientists from University of Southampton and the National Oceanography Centre Southampton (NOCS) has identified a crucial process behind the reason why dissolved organic carbon (DOC) levels in the deep oceans are constant despite a continuous supply from the surface ocean.
Most recreational anglers who target deep-water reef fish in Florida recognize barotrauma symptoms, and University of Florida researchers think they can teach the other 30 percent to help save the fish. By doing so, anglers would play a key role in sustaining the state’s valuable fisheries.
As much as 47 percent of the edible U.S. seafood supply is lost each year, mainly from consumer waste, new research from the Johns Hopkins Center for a Livable Future (CLF) suggests.
NMSU researchers have created a new underwater stimulation system to study electrical activity in certain aquatic animals.
An international team of scientists has discovered a new lineage of extinct plankton-feeding sharks, Pseudomegachasma, that lived in warm oceans during the age of the dinosaurs nearly 100 million years ago. The fossil sharks had tiny teeth very similar to a modern-day, plankton-eating megamouth shark.
University of Washington researchers have found the types of organisms in Seattle’s Elliott Bay change depending on the shoreline nearby, either armored or restored beaches. Young chum salmon adjusted their diets based on these changes.
New research from the University of Washington's Friday Harbor Laboratories shows that a more acidic ocean can weaken the protective shell of a delicate alga. The findings, published Sept. 9 in the journal Biology Letters, come at a time when global climate change may increase ocean acidification.
A greater understanding and appreciation of our oceans is essential for the wellbeing of the world’s population, according to the Global Marine Technology Trends 2030 (GMTT 2030) report launched today (Monday 7 September).
The tiny, beautiful sea sapphire dazzles observers with its ability to turn various jewel-like colors – and become invisible. The Weizmann Institute’s Prof. Lia Addadi, Prof. Steve Weiner, and others reveal how Sapphirinidae pulls off its magic trick, which could have applications such as adaptive reflective coatings and optical mirrors.
Restoring oyster reefs is not an easy task, but by digging deep and examining centuries-old reefs, marine restoration professionals may stand a better chance at bringing oysters back, said a new Cornell University and Paleontological Research Institution (PRI) study published in the August issue of the Journal of Shellfish Research.
Smithsonian scientists and colleagues have discovered a new genus and species of river dolphin that has long been extinct. They made the discovery after carefully examining fossil fragments from Panama. The fossil fragments also shed new light on the evolution of today’s freshwater river dolphin species.
In early August, biologist Peter Ward returned from the South Pacific with news that he encountered an old friend, one he hadn’t seen in over three decades. The University of Washington professor had seen what he considers one of the world’s rarest animals, a remote encounter that may become even more infrequent if illegal fishing practices continue.
A rare longfin mako shark satellite-tagged near Cuba recently “phoned home” off the U.S. Atlantic coast, say Mote Marine Laboratory scientists and colleagues who tagged the mako during the first-ever expedition to satellite-tag sharks off Cuba.
