A new report from researchers at Woods Hole Oceanographic Institution (WHOI) reveals for the first time the unseen—and somewhat surprising—benefits that people receive from the ocean’s twilight zone. Also known as the “mesopelagic,” this is the ocean layer just beyond the sunlit surface.
Using a new “non-targeted” approach, University of Washington and UW Tacoma researchers screened samples from multiple regions of Puget Sound to look for potentially harmful compounds that might be present.
Four new species of tropical sharks that use their fins to walk are causing a stir in waters off northern Australia and New Guinea.
Fibropapillomatosis (FP) is the most significant infectious disease affecting sea turtle populations worldwide. FB leads to tumors on the turtles’ eyes, flippers and internal organs and is widespread in warmer climates like Florida. A large-scale study evaluated tumor score, removal and regrowth in rehabilitating green sea turtles with FP in the southeastern U.S. from 2009 to 2017, and found that 75 percent did not survive following admission into a rehabilitation facility, irrespective of whether or not tumor regrowth occurred after surgery.
Arctic sea ice cannot "quickly bounce back" if climate change causes it to melt, new research suggests.
How did the monstrous giant squid - reaching school-bus size, with eyes as big as dinner plates and tentacles that can snatch prey 10 yards away -- get so scarily big?
A newly developed method can detect even low-dose human exposure to microcystins and nodularin in human urine. During harmful algal blooms (HABs), species of cyanobacteria release toxic peptides, including microcystins and nodularin into waterways, impacting wildlife and humans living in these marine environments. These findings are the first to report microcystin concentrations directly from exposed residents impacted by cyanobacteria in Florida, and is a critical step in developing and interpreting clinical diagnostic tests for HABs exposure worldwide.
In this week's issue of Science, marine scientists make the case for the United Nations to include mobile marine protected areas in the U.N. Convention on the Law of the Sea, or UNCLOS, now being updated since its last signing in 1982.
The essential roles that microbes play in deep-sea ecosystems are at risk from the potential environmental impacts of mining.
When nearly one million common murres died at sea and washed ashore from California to Alaska in 2015 and 2016, it was unprecedented — both for murres, and across all bird species worldwide. Scientists from the University of Washington, the U.S. Geological Survey and others blame an unexpected squeeze on the ecosystem's food supply, brought on by a severe and long-lasting marine heat wave known as "the blob."
Unprecedented numbers of common murres—North Pacific seabirds—died between 2015 and 2016. A new analysis lays out the scope of this event and suggests a potential culprit: severely reduced food supplies resulting from unusually elevated sea temperatures.
Those nice new clothes you got for Christmas or in the new year sales might just last longer, thanks to advice from scientists researching the impact washing machines have on clothes and the environment.
Researchers in China demonstrated a robotic gripping mechanism that mimics how a sea anemone catches its prey. The bionic torus captures and releases objects by crimping its skin. The grasper not only is relatively cheap and easy to produce but also can grab a variety of objects of different sizes, shapes, weights and materials. They discuss their work in this week’s Applied Physics Letters.
Richard Murray, Deputy Director and Vice President for Research at Woods Hole Oceanographic Institution (WHOI), will testify before the Committee on Science, Space, and Technology of the U.S. House of Representatives on January 15, 2020.
Nearly half of the fish caught worldwide are from stocks that are scientifically monitored and, on average, are increasing in abundance. Effective management appears to be the main reason these stocks are at sustainable levels or successfully rebuilding, according to a new study led by the University of Washington.
Cardiff University scientists have shed new light on the Earth's climate behaviour during the last known period of global warming over 14 million years ago.
A hybrid remotely operated vehicle developed by Woods Hole Oceanographic Institution (WHOI) took the first known automated sample performed by a robotic arm in the ocean. Last month, an international team of researchers used one of WHOI’s underwater robots, Nereid Under Ice (NUI), to explore Kolumbo volcano, an active submarine volcano off Greece’s famed Santorini island.
The mysterious disappearance of Greenland's Norse colonies sometime in the 15th century may have been down to the overexploitation of walrus populations for their tusks, according to a study of medieval artefacts from across Europe.
A team of researchers from the Mechanobiology Institute at the National University of Singapore investigated the science behind the formation of the ‘V’ patterns – also known as chevron patterns – in the swimming muscles of fish. The study focused on the myotome (a group of muscles served by a spinal nerve root) that makes up most of the fish body. These fish muscles power the fish’s side-to-side swimming motion and the chevron pattern is thought to increase swimming efficiency. The research team found that these patterns do not simply arise from genetic instruction or biochemical pathways but actually require physical forces to correctly develop.
Coastal wetlands provide stunning views and are hosts to a vast biodiversity. But they provide another service to the warming Earth: they capture carbon from the atmosphere and sequester it in their sediment at high rates. In the United States alone, coastal wetlands can offset the yearly carbon dioxide emissions from 800,000 cars. But as sea level rises with climate change, will coastal wetlands be overwhelmed, or will they retain their power as carbon sinks?
Existing genetic variation in natural populations of Mediterranean mussels allows them to adapt to declining pH levels in seawater caused by carbon emissions. A new study by biologists from the University of Chicago shows that mussels raised in a low pH experimental environment grew smaller shells than those grown at normal pH levels, but the overall survival rate of mussels grown under both conditions was the same.
While many conservation plans focus on only environmental indicators for success, the Wildlife Conservation Society (WCS)’s coral reef program is trying a relatively new approach: focusing on both social and ecological processes and outcomes to ensure a long-term future for coral reef systems, according to a newly published study.
An international team of geoscientists led by Caltech has used fiber optic communications cables stationed at the bottom of the North Sea as a giant seismic network, tracking both earthquakes and ocean waves.
Microorganisms play important roles in the health and protection of coral reefs, yet exploring these connections can be difficult due to the lack of unspoiled reef systems throughout the global ocean. A collaborative study led by scientists at the Woods Hole Oceanographic Institution (WHOI) and the Centro de Investigaciones Marinas - Universidad de La Habana (CIM-UH) compared seawater from 25 reefs in Cuba and the U.S. Florida Keys varying in human impact and protection, and found that those with higher microbial diversity and lower concentrations of nutrients and organic carbon—primarily caused by human activities—were markedly healthier.
Ocean scientists investigate the internal body clocks of sea anemones to determine if fluctuating temperatures play a role in their daily rhythms.
Researchers in Environmental Science & Technology report that a large desalination plant in Australia has the unexpected benefit of attracting some species of fish, increasing their abundance at the discharge site.
The wind over deep-sea waters offers the potential to become one of the country’s largest renewable energy sources. University of Texas at Dallas researcher Dr. Todd Griffith has spent years working on an offshore turbine design that can convert those deep-ocean winds into electricity. Recently, Griffith received a $3.3 million grant from the U.S. Department of Energy to take his technology to the next level. The Advanced Research Projects Agency-Energy (ARPA-E) award provides support for his team to design and build a prototype for a floating offshore wind turbine. The new grant was part of $26 million in funding from ARPA-E for 13 projects to accelerate floating offshore wind turbine technologies through the Aerodynamic Turbines, Lighter and Afloat, with Nautical Technologies and Integrated Servo-Control (ATLANTIS) program.
U.S. Representative Charlie Crist (D-FL), along with Representatives Steven Palazzo (R-MS), Alan Lowenthal (D-CA), and Chris Smith (R-NJ), introduced the Regional Ocean Partnership Act (H.R. 5390). The bill would authorize Regional Ocean Partnerships as partners with the federal government to address ocean and coastal concerns. It will provide with more consistent funding to help perform the critical mission of supporting ocean and coastal health, sustainability, and resiliency.
Large, old Chinook salmon have mostly disappeared from the West Coast. A new University of Washington and NOAA study points to the recent rise of resident killer whales, and their insatiable appetite for large Chinook salmon, as the main driver behind the decline of the big fish.
Exposure to underwater pile driving noise, which can be associated with the construction of docks, piers, and offshore wind farms, causes squid to exhibit strong alarm behaviors, according to a study by Woods Hole Oceanographic Institution (WHOI) researchers published Dec. 16, 2019, in the journal Marine Pollution Bulletin.
An extraordinary scientific collection of archived fish, as well as fish and water quality data taken from the Hudson River over more than five decades, has been gifted by Entergy Corporation (Entergy), to the Stony Brook University School of Marine and Atmospheric Sciences (SoMAS).
If you want to know how climate change and hypoxia -- the related loss of oxygen in the world’s oceans -- affect fish species such as the economically important Baltic cod, all you have to do is ask the fish. Those cod, at least, will tell you that hypoxia is making them smaller, scrawnier and less valuable. A paper published today in the journal Biology Letters points to a link between hypoxia and fish well-being.
Researchers at the University of New Hampshire have been awarded a three-year grant from the National Oceanic and Atmospheric Administration (NOAA) in partnership with Saildrone, Inc. of Alameda, CA, and the Monterey Bay Aquarium Research Institute (MBARI) to develop data quality tools for a new unmanned wind-powered sailboat-like vehicle capable of long-duration missions to collect vital ocean mapping information.
Dead zones within the world's oceans - where there is almost no oxygen to sustain life - could be expanding far quicker than currently thought, a new study suggests.
If coral reefs are the canary to the ocean's coal mine, it's getting awfully bleak in the Gulf of Mexico.
Stormquakes are a recently discovered phenomenon characterized by seismic activity originating at the ocean floor due to powerful storms. Heavy storms, like hurricanes or nor'easters, can create seismic waves as large as magnitude 3.5 quakes. These tremors caused by the effects of storms on the seafloor are what researchers call stormquakes. Catherine de Groot-Hedlin, who was part of the group that first observed stormquakes, will discuss their properties and meteorological significance at the 178th ASA Meeting.
Fisheries acoustics have been studied for over 40 years to assess biomass and optimize aquaculture applications, and researchers in France have examined the phenomenon of how fish scatter acoustic waves in a dense school of fish contained in an open-sea cage. They developed an approach to help overcome issues encountered in aquaculture relating to the evaluation of the total biomass of dense schools of fish. They will discuss their work at the 178th ASA Meeting.
In partnership with the government of the Dominican Republic, researchers at the Indiana University Center for Underwater Science have opened their fifth "Living Museum in the Sea" in the Caribbean country -- a continuation of the center's holistic approach to protecting and preserving historic shipwrecks as well as their coastal environments.
Microbial communities inside whales may play an important role in the digestion of one of the ocean’s most abundant carbon-rich lipids, known as a wax ester.
Little bits of black carbon littering the ocean floor, separate and distinct from the organic carbon believed to come from the ocean’s surface. The source of that strange, and older, carbon has now been identified by UD researchers. The discovery is an important step in understanding the marine carbon cycle.
A new experiment by the University of Washington has found that some corals are more likely to eat microplastics when they are consuming other food, yet microplastics alone are undesirable.
