Similar objects have been found on the opposite side of the Gulf, in Florida, and a bit further south.
Microplastics are considered a major environmental hazard that is produced from the disintegration of plastics. Sadly, many of them end up in oceans and pollute or contaminate the waters and marine life. Now, a new study shows that long sunlight exposure could break down plastics and transform them into a soup of new chemicals and eliminate the hazards of microplastics.
New collaborative research from the Woods Hole Oceanographic Institution and five partner institutions (University of Arizona,, Pennsylvania State University, Desert Research Institute and University of Bergen), published on September 9, 2021, in , reveals that during past periods glaciers and ice caps in coastal west Greenland experienced climate conditions much different than the interior of Greenland.
Lonati’s methodology involves looking for whales, then hovering the university’s dual-gimbal DJI Matrice 210 V2 drone over a whale when it surfaces, capturing high-resolution images using an RGB camera at 20m above the ocean surface, then descending to 10m to capture a reading of the whale’s internal body temperature via its blowhole using an infrared camera. It is worth noting that drones have been deployed by researchers before to gather information about whales.
“When we analyzed several other Low Sulfur Fuel Oils, we found some contained higher concentrations of toxic components than the oil discharged in the Mauritius spill, so more research will be needed before we can conclude that all the oil types within this new class pose less of a threat to marine ecosystems than heavy fuel oils.”
“This is critical infrastructure to what we do,” said Rob Munier, WHOI vice president for marine facilities and operations. “Others can contemplate alternatives, including retreat (from the waterfront), but we have to be there. It’s part of our ability to do our mission.”
Icy moons that have (or are thought to have) subsurface oceans are common in the outer solar system. For example, Jupiter has several of them. These form when gravity from the planet they orbit stretches and squeezes their interior.
The findings could shed light on how climate change will affect Greenland’s vast frozen interior as the planet warms and surface melting increase.
Special equipment is required to visit these extreme depths, which is why less than 5% of this area has been explored and charted.
The process, known as clay flocculation, involves spraying a mixture of clay particles and seawater onto the red tide algae.
Aquaculture already supplies more than half of the world’s seafood consumed by humans, with seaweed totaling 27% of annual global aquaculture tonnage.
When our time comes, will the Cape and Islands be looking at something a lot bigger and stronger than Bob, or Carol, or the Hurricane of ’38 or even the Great Colonial Hurricane of 1635?
“Scientific communities need to come together to have discussions about what we can tell from our data, how we can compare apples and oranges, and how we can bring all this information together to have a better understanding of the entire Indian Ocean system,” Ummenhofer says.
It is “unequivocal” that human influence has warmed the planet and that widespread, rapid changes have already occurred in every region of the globe as a result. The scale and rate of changes are “unprecedented” in relation to the past hundreds to thousands of years. And there are more changes on the way.
Extreme events observed through recent satellite records amplified the projected declines from previous studies, researchers said.
Enter Mesobot, a state-of-the-art aquatic explorer designed to help unravel some of those unknowns, and improve our existing knowledge.
A high-tech SharkCam invented by a Cape Cod researcher offers an unprecedented window into the lives of the ocean’s toothy predators, and can also extend to seals, whales, turtles and squid for a big-picture view of precious ecosystems and how to protect them. “These vehicles, these underwater robots that look like highly complex systems are just an extension of yourself to be able go where people can’t go, and there’s no limitation to what they can do,” said Amy Kukulya, research engineer and principal investigator at Woods Hole Oceanographic Institution.
WASHINGTON (AP) — With climate change threatening the sea ice habitat of Emperor penguins, the U.S. Fish and Wildlife Service on Tuesday announced a proposal to list the species as threatened under the Endangered Species Act. “The lifecycle of Emperor penguins is tied to having stable sea ice, which they need to breed, to feed and to molt,” said Stephanie Jenouvrier, a penguin ecologist at the Woods Hole Oceanographic Institution.
In September of 2017, Woods Hole Oceanographic Institution postdoctoral scholar Maggie Johnson was conducting an experiment with a colleague in Bocas del Toro off the Caribbean coast of Panama. After sitting on a quiet, warm open ocean, they snorkeled down to find a peculiar layer of murky, foul-smelling water about 10 feet below the surface, with brittle stars and sea urchins, which are usually in hiding, perching on the tops of coral. This unique observation prompted a collaborative study explained in a new paper published on July 26, 2021, in Nature Communications analyzing what this foggy water layer is caused by, and the impact it has on life at the bottom of the seafloor.
There in the dark ocean, a unique food web thrives not on photosynthesis but on chemical energy from the venting fluids.
According to Phys.org, Johnson and her team snorkeled down the water, and there they found the peculiar layer of water that has brittle stars and sea urchins, which are uncharacteristically perching on the top of coral reefs as they are usually hiding.
Investigators suggest that loss of oxygen in the global ocean is accelerating due to climate change and excess nutrients, but how sudden deoxygenation events affect tropical marine ecosystems is poorly understood.
Murray said buoys, research ships and other coastal monitoring systems would be critical to predicting weather patterns and preparing for impacts on food supplies and local economies built around fishing.
