Ocean currents predicted on Enceladus
Buried beneath 20 kilometers of ice, the subsurface ocean of Enceladus—one of Saturn's moons—appears to be churning with currents akin to those on Earth......»»
Research shows the ocean is becoming too loud for oysters
Baby oysters rely on natural acoustic cues to settle in specific environments, but new research from the University of Adelaide reveals that noise from human activity is interfering with this critical process......»»
Study reveals historical mismatch in Southern Ocean contributes to heat and carbon uptake
The Southern Ocean plays a central role in the global uptake of heat and carbon, which is widely thought to be due to its unique upwelling and circulation. An international research team, led by the University of Liverpool, explored whether there are.....»»
How biodiversity is changing in one of the world"s most productive ocean ecosystems
In research published in Global Change Biology, investigators have examined DNA within ocean bottom sediment cores to assess changes in living organisms within one of the world's most productive marine ecosystems: the Atacama Trench in the eastern Pa.....»»
Mathematical models used to calculate speed of disease spread in early ocean travel
Two scientists at the University of California, Los Angeles, have developed a way to calculate the approximate speed of disease spread between distant places via ocean travel hundreds of years ago......»»
Estuaries and coastlines capture most plastic before it gets out to sea, providing a chance to stop ocean pollution
If you ask someone where plastic ends up, they will usually say the ocean. It's not a surprising answer because we have known since the 1970s that plastic is accumulating in the subtropical oceans, far from land......»»
"New El Niño" discovered south of the equator
A small area of the southwestern Pacific Ocean, near New Zealand and Australia, can trigger temperature changes that affect the entire Southern Hemisphere, a new study has found......»»
Mini-Neptune turned out to be a frozen super-Earth
The density makes it look like a water world, but its dim host star keeps it cool. Enlarge / Renditions of a possible composition of LHS 1140 b, with a patch of ocean on the side facing its host star. Earth is included at right f.....»»
Signatures of life could survive near surfaces of the moons Enceladus and Europa, NASA experiment suggests
Europa, a moon of Jupiter, and Enceladus, a moon of Saturn, have evidence of oceans beneath their ice crusts. A NASA experiment suggests that if these oceans support life, signatures of that life in the form of organic molecules (e.g. amino acids, nu.....»»
Diatom surprise could rewrite the global carbon cycle
When it comes to diatoms that live in the ocean, new research suggests that photosynthesis is not the only strategy for accumulating carbon. Instead, these single-celled plankton are also building biomass by feeding directly on organic carbon in wide.....»»
Mega-iceberg melt affects important marine ecosystem
Scientists have for the first time taken in-situ ocean measurements during the collapse of a giant iceberg in the sub-Antarctic. These new observations reveal how ocean ecosystems may be affected if more icebergs calve due to warmer ocean temperature.....»»
Cape Cod scientists want to dump 60,000+ gallons of sodium hydroxide into ocean in climate change experiment
Environmentalists and fishermen are pushing back against a plan from a group of scientists who want to dump more than 60,000 gallons of sodium hydroxide, more commonly known as lye, into the ocean off Cape Cod to gain an understanding of how to slow.....»»
The salmon diaries: Life before and after Klamath Dam removal
When salmon return from the ocean to the Klamath River after the world's largest dam removal project ends this fall, they will regain access to 400 miles of historical spawning habitat their species has been cut off from for more than a century......»»
World"s rarest whale may have washed up on New Zealand beach, possibly shedding clues on species
Spade-toothed whales are the world's rarest, with no live sightings ever recorded. No one knows how many there are, what they eat, or even where they live in the vast expanse of the southern Pacific Ocean. However, scientists in New Zealand may have.....»»
Researchers discover novel deepwater renewal process in Lake Geneva
EPFL researchers have discovered that deepwater renewal in Lake Geneva in wintertime is not only due to vertical mixing. Instead, strong currents coming from the lake's Petit Lac basin and nearshore zones of the Grand Lac play a vital role......»»
Webb investigates eternal sunrises, sunsets on distant world
Researchers using the James Webb Space Telescope have finally confirmed what models have previously predicted: An exoplanet has differences between its eternal morning and eternal evening atmosphere. WASP-39 b, a giant planet with a diameter 1.3 time.....»»
Climate model suggests extreme El Niño tipping point could be reached if global warming continues
A trio of physicists and oceanologists, two with the University of Cologne's Institute of Geophysics and Meteorology and the third with the GEOMAR Helmholtz Center for Ocean Research Kiel, all in Germany, has found via the CESM1 climate model that an.....»»
Loss of oxygen in bodies of water identified as new tipping point
Oxygen concentrations in our planet's waters are decreasing rapidly and dramatically—from ponds to the ocean. The progressive loss of oxygen threatens not only ecosystems, but also the livelihoods of large sectors of society and the entire planet,.....»»
Australian swimmer caught in riptides rescued using his Apple Watch
A 49-year-old experienced swimmer in New South Wales used his Apple Watch to call for help after becoming caught in an ocean current that was dragging him further out to sea.Shearman's Apple Watch was credited with saving his life. (credit: Surf Life.....»»
Nearby exoplanet could be first known ocean world: Webb telescope
A planet relatively close to Earth could be the first ever detected with a potentially life-sustaining liquid ocean outside our Solar System, according to scientists using the James Webb space telescope......»»
Melting ice no guarantee of smooth sailing in fabled Arctic crossing: Study
Melting sea ice in the fast-warming Arctic Ocean is not making it easier for sailors to navigate a legendary shortcut between Europe and Asia despite popular belief, scientists said Thursday......»»
