To find out, Sheldon and his colleagues hauled buckets of seawater up to the Hudson’s laboratory and used a plankton-counting machine to total up the size and number of creatures they found.
“It's a complex mixture of chemistry, biology, and physics,” says Scripps oceanographer Grant Deane, co-principal investigator of Soars.Up until now, scientists could run complex computer climate models to estimate, say, how increasing CO2 levels might change the chemistry of surface waters.
“It’s like the power of invisibility,” says Pomerantz, lead author of a recent study in the Journal of Experimental Biology that examines how clear wings develop.In ocean environments there are lots of transparent species, but on land it’s much less common.
Their energy potential is astonishing—researchers estimate that waves off the coasts of the United States could generate as much as 2.64 trillion kilowatt-hours annually, equivalent to 64 percent of the country’s total electricity generation in 2019.But capturing the immense power radiating across our oceans’ surfaces is no easy feat—wave energy technology is challenging to engineer, startup costs are high, and testing in open ocean waters is a regulatory nightmare.
“If you actually put your head underwater and take the time to listen, it's amazing what you'll hear,” Radford says.
New research published in premier science journal Nature last week, with input from NIWA, showed the global population of oceanic sharks and rays has declined by more than 70 per cent in the past 50 years, with ongoing decline likely to lead to the extinction of some species.
After nearly two decades as an oceanographer at NASA’s Jet Propulsion Laboratory, Chao had left the space agency to commercialize a seafaring generator that can harness the limitless thermal energy trapped in the world’s oceans.
The ship leaves Wellington and heads south with 20 science staff and 19 crew on board to learn more about key environmental and biological processes in the Ross Sea. Voyage leader and fisheries scientist Dr Richard O’Driscoll says this is the third in a series of voyages focused on providing baseline information about the Ross Sea Marine Protected Area (MPA) established in 2017.
Since he first started working on Alvin as an engineer nearly 25 years ago, Strickrott has logged more than 2,000 hours in the deep ocean, where he learned to expertly navigate the seabed’s alien landscape and probe for samples with the submarine’s spindly robotic arms.
The products are plant-based, smell fantastic, and are much more sustainable overall than buying new plastic bottles every month.Kinflyte's garments are made of recycled polyester knits from post-consumer plastic bottles, so they're eco-friendly too.
The expedition’s chief scientist, Lisa Levin, a professor of integrative oceanography at the Scripps Institution of Oceanography, says the goal of the cruise is to understand the habitat and how animals interact with the mineral-laden rocks.
Voyage leader and NIWA marine geologist Dr Joshu Mountjoy says this is the first time this technology has been used to survey submarine canyons in New Zealand waters and information collected will lead to new understanding relevant to many of the world’s continental margins.
John Brosnan waits on board the RV Kaharoa after returning to New Zealand from an epic 75-day voyage.NIWA has deployed more than 1100 Argo floats in the Pacific, Indian and Southern Ocean over 22 voyages since 2004, more than any other individual vessel.
A network of state-of-the-art tsunami buoys is being deployed from New Zealand up into the Pacific to keep communities safer.Every 15 seconds the BPR records the height of the ocean above it and sends that information to the surface buoy once an hour.
Regardless, Athey and her colleagues landed on a startling figure: A single pair of jeans may release 56,000 microfibers per wash.This landed them at an even more startling figure: Those two plants alone could be unloading a billion indigo denim microfibers per day into the lake.
Macroplastics like bags and bottles are breaking into microplastics (defined as bits less than 5 millimeters long) that swirl in the water column and sink down to the seafloor .Writing today in the journal Nature Communications, scientists from the National Oceanography Centre in the United Kingdom say they can account for that missing plastic, and in the process reveal the stunning scale of the microplastic pollution problem.
Coronavirus delays have already disrupted other voyages in the international Argo float programme and NIWA oceanographer Dr Phil Sutton says this could lead to data gaps in the research.
It might surprise you to know that in the United States there are several hundred cities that intentionally discharge untreated, raw sewage into their coastal waters whenever their sewer systems are overwhelmed with stormwater.
As weather systems tracked toward New Zealand from the west and north, they lacked moisture because of cooler eastern Indian Ocean seas caused by the IOD.NIWA’s climate change expectations suggest spring average rainfall decreases for northern New Zealand, including Auckland.
For decades, scientists have turned to the Labrador Sea to understand how ocean processes there may be affecting the strength of a massive oceanic conveyor belt known as the Atlantic Meridional Overturning Circulation.
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.
Space Photos of the Week: Salt of the Jupiter Moon. Space photos and potato chips, bet you can’t have just one or two or three or four.
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.
