A little over a year ago, a group called The Ocean Cleanup launched an unprecedented campaign to rid the seas of plastic, complete with an unprecedented device: a 600-meter-long, U-shaped tube that was meant to passively gather debris in the Great Pacific Garbage Patch for a ship to come along and scoop up and take back to land.
When hurricane winds temporarily plug up the Gulf Stream flow, that water sloshes back against the coastline, Ezer and other researchers have found, including flooding his neighborhood.“We started seeing flooding when Dorian was stuck near the Bahamas,” says Ezer, an earth scientist at Old Dominion University.
NIWA coastal physicist Dr Joanne O’Callaghan is part of a working group aiming to establish a collaborative New Zealand ocean observing network.Climate change is making its presence felt in New Zealand waters with marine heatwaves, increasing ocean acidification and sea level rise.”.
The seas continue to take on the atmosphere’s heat, as marine heatwaves cripple ecosystems and less snow and ice threaten water supplies.Let’s begin with the most apparent consequence of climate change in the oceans: global mean sea level rise.
Understanding how the Antarctic oceans work is vital to predicting the world’s future climate and the implications of climate change for humankind and the planet.
For one, microplastic is swirling in Monterey Bay’s water column at every depth they sampled, sometimes in concentrations greater than at the surface of the infamous Great Pacific Garbage Patch.
The specks materializing even in human feces .Now scientists have exposed a potential new consequence of the plastic menace: The toxins the material leaches into seawater inhibit the growth and photosynthetic efficiency of the bacteria Prochlorococcus , which is responsible for producing an estimated 20 percent of the oxygen we breathe.
Moreover, the researchers inferred the existence of five community-level groups of viruses that mapped onto distinct marine ecological zones based on temperature and depth: Arctic, Antarctic, temperate and tropical surface, temperate and tropical subsurface, and deep ocean.
The organization tested 449 fish from more than 250 restaurants, seafood markets, and grocery stores across the country and found that 21 percent of samples were mislabeled.
The number of heat waves affecting the planet’s oceans has increased sharply, scientists have revealed, killing swathes of sea life like “wildfires that take out huge areas of forest.” The damage caused in these hotspots is also harmful for humanity, which relies on the oceans for oxygen, food, storm protection and the removal of climate-warming carbon dioxide the atmosphere, they say.
Data gathered during that underwater expedition, which lasted more than 50 hours and covered some 60 miles, is now being fed into climate models to better predict how fast the ice shelf might melt and how its disappearance will affect global sea level rise, the British Antarctic Survey says.
Dr Egan and her team will be studying the ear bones of glass eels to learn more about their spawning locations and larval oceanic movements. In this new project, migrating female eels will be tagged and their location communicated to satellites to help pinpoint their spawning grounds in the western Pacific Ocean.
“This study unequivocally demonstrates that earthquake-triggered canyon flushing is the primary process that carves out submarine canyons and delivers coastal sediment to the deep ocean,” says NIWA marine geologist Dr Joshu Mountjoy.
It’s measured as the height of the water above the normal predicted tide, and how bad it is depends mainly on three things: wind speed, shoreline shape, and timing.https://twitter.com/NHC_Surge/status/1049770886943924224Typically, the strongest surge occurs with the eyewall of the storm.
Emergency rescue teams were trying to reach about 150 others still trapped in cars, on roofs and in their attics.Greenville lies far inland, a few score miles west of the Atlantic Ocean, but it is connected to the sea by the Tar River, which eventually becomes the Pamlico River as it widens out and flows into the Atlantic.On Thursday, as billowing, dark heather clouds loomed overhead, the city’s spokesman, Brock Letchworth, said Greenville’s first concern is that Florence could drop enough water to create immediate flash flooding.But he said the city was also worried about a massive salty storm surge roaring westward up the river from the Atlantic.
One basin in particular, the normally cool Gulf of Maine in the Northwest Atlantic Ocean, has seen several heat waves in recent years and has spent most of 2018 with unusually warm water temperatures.
This week, Southeast Asia and southern China are bracing for Super Typhoon Mangkhut.Cyclones in the Indian Ocean are classified according to two intensity scales depending on where they are, with names like “very intense tropical cyclone” and “super cyclonic storm.” Australia rates cyclones from categories 1 to 5.So why the three different words?
Future booms are estimated to cost about $5.8 million each.Major sponsors include Marc Benioff, the chief executive of Salesforce.com, and Peter Thiel, the co-founder of PayPal.Skeptics questioned whether this was the most economically efficient way to address the problem.“I fully agree that this is not the full solution to plastic pollution,” Mr. Slat said.While it’s necessary to prevent more plastic from entering the ocean, what is there already isn’t going to go away by itself, he added.“We have to clean it up at some point in time and, actually, I would say the sooner the better,” he said.
The free-floating Ocean Cleanup system may well snag the bits at the surface, but with a screen made of woven polyurethane that hangs down 3 meters at its lengthiest, it’s limited in what it can reach.“There's also the fact that you're collecting and aggregating plastics, and so that's actually going to attract more animals to it,” says Martini.
During years with low seasonal sea ice concentrations (when there’s more heat loss from more exposed open water), the north-south differences in atmospheric temperatures across the Barents Sea are reduced.
Oceanographers from the University of East Anglia (UEA) came across their finding after deploying a team of robot submarines in the Gulf of Oman.Their collected data found a monstrous dead zone the size of the US state of Florida – and the area is unfortunately spreading.Dead zones, or Oxygen Minimum Zones, are areas with extremely low levels of oxygen in bodies of water such as oceans and large lakes.Dr Bastien Queste from UEA’s School of Environmental Sciences said: “Dead zones are areas devoid of oxygen.
THE Baltic Sea acts as a TIME MACHINE to scientists which allows researchers to peer into the future to see how oceans in the rest of the world over time and to mark them against how they used to be, a new study states.
Climate change: Heat below Arctic is MELTING ice - sea levels WILL rise THE ARCTIC ice is being attacked by warmth from all fronts, according to new research which could exacerbate the problem of rising sea levels.
With more than 100 scientists and crew from nearly 30 research institutions, EXPORTS is the first coordinated multidisciplinary science campaign of its kind to study the pathways, fates and carbon cycle impacts of microscopic and other plankton using two research vessels, a range of underwater robotic platforms and satellite imagery.
A warm region of water trapped deep below the surface of the Arctic seas north of Canada has the potential to leave the entire area devoid of ice.
