Each year, many shark species migrate hundreds of miles, traversing ocean waters to return to the same spot year after year. Now, Florida State University researchers have found that sharks likely use the Earth’s magnetic fields to help guide them on these long-distance journeys.
A massive collaborative research project covered in the journal Nature this week offers projections to the year 2100 of future sea-level rise from all sources of land ice, offering the most complete projections created to date.
Woods Hole, Mass. (May 5, 2021) – Students and educators have grown accustomed to distance learning over the past year. But a new twist in remote learning kicked off on May 3 when Woods Hole Oceanographic Institution (WHOI) launched its seventeenth Dive and Discover expedition, an 18-day science research cruise out of Vigo, Spain to explore the ocean’s midwater, or twilight zone. Started in 2000, Dive and Discover is WHOI’s popular public outreach and educational platform, providing daily updates from some of the most remote locations on the planet. On this mission, virtual participants will follow along aboard the Spanish research vessel Sarmiento de Gamboa as scientists and engineers use some of the most advanced research tools available to study the twilight zone, which lies just beneath the sunlit surface waters and teems with life. The Sarmiento de Gamboa will be joining two others that are a part of the NASA-funded EXPORTS mission operating in the same location
A new Cornell University-led study examines how temperature affects fishing behavior and catches among inland fisher households in Cambodia, with important implications for understanding climate change.
Woods Hole, Mass. (April 28, 2021) --Woods Hole Oceanographic Institution (WHOI) today announced the establishment of the Francis E. Fowler IV Center for Ocean and Climate to seek new knowledge and new solutions at the intersection of oceanography and climate science. A generous gift from Francis E. Fowler IV established the center and will enable it to immediately commence operations.
New Curtin research has found urgent action is needed to ensure man-made underwater noise in Australian waters does not escalate to levels which could be harmful to marine animals, such as whales, and negatively impact our pristine oceans.
In an effort to fight the millions of tons of marine litter floating in the ocean, Florida State University researchers have developed a new virtual tool to track this debris. Their work, which was published in Frontiers in Marine Science, will help provide answers to help monitor and deal with the problem of marine litter.
Industrial fleets from countries around the world have been increasingly fishing in African waters, but with climate change and increasing pollution threatening Africa’s fish stocks, there is a growing concern of the sustainability of these marine fisheries if they continue to be exploited by foreign countries.
The Piotrowski Lab has reported newly identified invasive ionocytes in the sensory organs of larval and adult zebrafish fish that may provide clues to how sensory organs continue to function in changing environments.
An interdisciplinary group of Spanish scientists, bringing together biologists and chemists from the Universities of Seville, Huelva, the Autonomous University of Madrid and the Institute of Marine Sciences of Andalusia of the CSIC in Cadiz, have just published the results of their pioneering research studying the management of marinas.
Corals and sponges are important foundations in ocean ecosystems providing structure and habitats that shelter a high number of species like fish, crabs and other creatures, particularly in the seamounts and canyons of the deep sea. Researchers at the University of New Hampshire have discovered that when it comes to climate change not all deep-sea corals and sponges are affected the same and some could be threatened if average ocean temperatures continue to increase in the deep sea of the Northwest Atlantic.
An antibiotic used to treat bacterial infections in humans is showing promise in treating stony coral, found throughout the tropical western Atlantic, including several areas currently affected by stony coral tissue loss disease. Preserving M. cavernosa colonies is important due to its high abundance and role as a dominant reef builder in the northern section of Florida’s Coral Reef. Results show that the Base 2B plus amoxicillin treatment had a 95 percent success rate at healing individual disease lesions.
A new study suggests the white shark population for the eastern north Pacific, especially those listed in the Gulf of California, might be underestimated. Researchers found that the mortality rates for these white sharks might be underestimated as well, as an illicit fishery for the species was uncovered in the Gulf of California, suggesting that fishers were killing many more white sharks than has been previously understood.
An international group of scientific experts co-directed by CNRS oceanographer Jean-Pierre Gattuso* has stated the requirements for coral reef survival in an article published in Biological Conservation.
The two major types of cetaceans appear to have evolved their characteristic blowholes through different anatomical transformations, according to a study being presented at the American Association for Anatomy annual meeting during the Experimental Biology (EB) 2021 meeting, held virtually April 27-30.
Woods Hole, Mass. and Wilmington, Mass. (April 20, 2021) - Woods Hole Oceanographic Institution (WHOI) and Analog Devices, Inc. (Nasdaq: ADI) today launched the Ocean and Climate Innovation Accelerator (OCIA) consortium. ADI has committed $3 million over three years towards the consortium which will focus on advancing knowledge of the ocean’s critical role in combatting climate change as well as developing new solutions at the intersection of oceans and climate.
Corals are part of a highly complex ecosystem, but it remains a mystery if and how they might communicate within their biological community. In a new study, researchers found evidence of sound-related genes in corals, suggesting that the marine invertebrates could use sound to interact with their surroundings.
Scientists at the University of Southampton have conducted a study that highlights the importance of studying a full range of organisms when measuring the impact of environmental change - from tiny bacteria, to mighty whales.
Today, over 1,200 coastal scientists, managers, and professionals from federal and state agencies, academia, non-profits, and industry came together for a virtual event launching the new Gulf of Mexico Conference (GoMCon). The Gulf of Mexico Alliance hosted this event in partnership with the Gulf of Mexico Research Initiative and Harte Research Institute for Gulf of Mexico Studies.
In a new project, a research team from Rensselaer Polytechnic Institute will build biosensors using bacteria that can sense and communicate levels of nutrients in a body of water with enhanced levels of sensitivity, scalability, and versatility. The effort, supported by a nearly $375,000 grant from the National Science Foundation, is being led by Shayla Sawyer, an associate professor of electrical, computer, and systems engineering at Rensselaer.
Charles Darwin, the British naturalist who championed the theory of evolution, noted that corals form far-reaching structures, largely made of limestone, that surround tropical islands. He didn’t know how they performed this feat. Now, Rutgers scientists have shown that coral structures consist of a biomineral containing a highly organized organic mix of proteins that resembles what is in our bones. Their study, published in the Journal of the Royal Society Interface, shows for the first time that several proteins are organized spatially – a process that’s critical to forming a rock-hard coral skeleton.
As the Rhode Island legislature considers designating the Northern Star Coral an official state emblem, researchers are finding that studying this local creature’s recovery from a laboratory-induced stressor could help better understand how to protect endangered tropical corals.
An international development team, led by researchers at the University of New Hampshire, has created a user-friendly software program that can process sound data collected from the world’s oceans in a more standardized format that will enhance research and collaboration and help understand the global sea soundscape dynamics, including the impact of COVID-19 when travel and economic slowdowns put a halt to human activities in the ocean.
Harmful algal blooms (HABs) occur in all 50 U.S. states and many produce toxins that cause illness or death in humans and commercially important species. However, attempts to place a more exact dollar value on the full range of these impacts often vary widely in their methods and level of detail, which hinders understanding of the scale of their socio-economic effects.
Sandia National Laboratories researchers are beginning to analyze the first seafloor dataset from under Arctic sea ice using a novel method. They were able to capture ice quakes and transportation activities on the North Slope of Alaska while also monitoring for other climate signals and marine life.
Overfishing likely did not cause the Atlantic cod, an iconic species, to evolve genetically and mature earlier, according to a study led by Rutgers University and the University of Oslo – the first of its kind – with major implications for ocean conservation.
Local alternative seafood networks (ASNs) in the United States and Canada, often considered niche segments, experienced unprecedented growth in the early months of the COVID-19 pandemic while the broader seafood system faltered, highlighting the need for greater functional diversity in supply chains, according to a new international study led by the University of Maine.
Cone snails use a previously undetected set of small molecules that mimic the effects of worm pheromones to drive marine worms into a sexual frenzy, making it easier to lure them out of their hiding places so the snails can gobble them up.
Water quality management in the ocean often targets visible pollution sources such as sewage, rivers or ships. A new global study, led by researchers at the University of Gothenburg, reveals that invisible groundwater discharges may be just as important driving nitrogen into coastal waters.
Climate change is altering the world we share with all living things. But it's surprisingly difficult to single out climate change as an extinction threat for any one particular species protected under the Endangered Species Act. To date, the U.S. Fish and Wildlife Service has only formally considered impacts from climate change in listing actions for four animal species and one alpine tree.
With a total length of up to 5.5m, the tiger shark is one of the largest predatory sharks known today. This shark is a cosmopolitan species occurring in all oceans worldwide. It is characterized by a striped pattern on its back, which is well marked in juveniles but usually fades in adults. An international team of researchers led by Julia Türtscher from the University of Vienna examined the fossil record of these apex predators and found out that modern tiger sharks are older than previously thought and that several tiger shark species existed in past compared to the single species living today.
The Gulf of Mexico Alliance is pleased to share several new projects as part of its ongoing Gulf Star Program. This year’s projects focus on supporting coastal resilience, underrepresented and underserved communities, citizen science water and marine debris monitoring, living shorelines, wildlife conservation, and regional data sharing.
A study offers the first fine-scale analysis of vertical movement of baby white sharks in the New York Bight. Their 3D movements along with oceanographic features like sea surface temperature show they traverse variable oceanographic features across the continental shelf in the New York Bight, but certainly have their habitat preferences. More than 90 percent of them were positioned within 20 kilometers of Long Island’s southern shoreline, which further confirms the importance of this region to baby white sharks.
A large gathering of fish tempts harbour porpoises to search for food around oil and gas platforms, even though the noise from these industrial plants normally to scare the whales away. Decommissioned platforms may therefore serve as artificial reefs in the North Sea.
Marine heatwaves are dramatically affecting the marine ecosystems of the world and the Mediterranean is no exception. In the Mediterranean, these extreme climate episodes and its resulting massive mortality of species are getting more and more intense and frequent.
