Deciphering the intensity of past ocean currents
Ocean currents determine the structure of the deep-sea ocean floor and the transport of sediments, organic carbon, nutrients and pollutants. In flume-tank experiments, researchers from MARUM—Center for Marine Environmental Sciences at the Universit.....»»
Study reveals large ocean heat storage efficiency during the last deglaciation
As one of the largest heat reservoirs in the climate system, the global ocean absorbs more than 90% of the excess energy from ongoing anthropogenic warming. In the last century, the greatest warming in the ocean has occurred in the upper 500 m, with.....»»
Sea surface micro layer: Researchers study boundary between the ocean and the air
The boundary between the ocean and the atmosphere, where the air and sea interact, is known as the sea surface microlayer. Understanding how nutrients, pollutants and organic matter are exchanged between the air and the sea is also vital for better u.....»»
Mysterious Pacific Ocean sounds identified as a type of whale—a new AI app helps track them
A team of oceanographers and marine biologists from the NOAA Pacific Islands Fisheries Science Center and Oregon State University has identified a mysterious noise heard in the Pacific Ocean for two decades as the sounds of Bryde's whales......»»
Cleaning the ocean has a price — and layers of complications
Pulling plastic from the ocean and recycling that into auto parts is the plan. The challenges are immense, but worth it......»»
Tropical cyclone intensity exacerbated by increasing depth of ocean mixed layer, finds study
Tropical cyclones can have severe consequences for both the marine and terrestrial environments, as well as the organisms and communities who inhabit them. In the oceans, there can be alterations in sea surface temperature that disrupt biological pro.....»»
Ocean waves grow way beyond known limits, new research finds
Scientists have discovered that ocean waves may become far more extreme and complex than previously imagined......»»
Ocean sediment is a "mudtropolis"—meet the carbon-cycling creatures thriving beneath the seabed
Sitting in darkness, deep below the sunlit surface, an iridescent nightmare awaits its prey. With precision and speed, it strikes and slices a passing fish clean in half with a set of jaws twice the width of its head. The armor-plated creature retrea.....»»
Scientists Will Engineer the Ocean to Absorb More Carbon Dioxide
A research consortium plans to revive geoengineering trials of the controversial iron fertilization technique to pull carbon dioxide from the air, despite public backlash.....»»
Record-Breaking Rainfall in Carolinas and Europe Explained
On opposite sides of the Atlantic Ocean, Central Europe and North Carolina have both been drenched by torrential rains.....»»
Mystery of Deep-Ocean ‘Biotwang’ Sound Has Finally Been Solved
A strange sound dubbed “biotwang” was first heard bouncing around the Mariana Trench 10 years ago, and scientists have finally figured out where it comes from.....»»
Europa Clipper: 8 things to know about NASA"s mission to an ocean moon of Jupiter
The first NASA spacecraft dedicated to studying an ocean world beyond Earth, Europa Clipper aims to find out whether the ice-encased moon Europa could be habitable......»»
"Marine identity" can help restore the ocean, say researchers
People's deep connection with the ocean—their "marine identity"—can help us reset society's relationship with the seas, new research led by Dr. Pamela Buchan, from the University of Exeter, suggests......»»
Gravity study gives insights into hidden features beneath lost ocean of Mars and rising Olympus Mons
Studies of gravity variations at Mars have revealed dense, large-scale structures hidden beneath the sediment layers of a lost ocean. The analysis, which combines models and data from multiple missions, also shows that active processes in the Martian.....»»
Generating spin currents directly using ultrashort laser pulses
An international team of physicists has found that it is possible to generate spin currents directly using certain kinds of ultrashort laser pulses. In their study, published in the journal Physical Review Letters, the group used a linearly polarized.....»»
New research reveals how El Niño caused the greatest ever mass extinction
Mega ocean warming El Niño events were key in driving the largest extinction of life on planet Earth some 252 million years ago, according to new research......»»
Microbe dietary preferences found to influence effectiveness of carbon sequestration in deep ocean
The movement of carbon dioxide (CO2) from the surface of the ocean, where it is in active contact with the atmosphere, to the deep ocean, where it can be sequestered away for decades, centuries, or longer, depends on a number of seemingly small proce.....»»
Wreck discovered of French steamship that sank in Atlantic in 1856
A US dive team has discovered the wreck of a French steamship, Le Lyonnais, that sank in the Atlantic Ocean in 1856 after a "hit-and-run" collision with an American sailing vessel, claiming 114 lives......»»
NASA"s EZIE mission set for 2025 launch
In 2025, NASA will launch its first mission to image the magnetic fingerprint of intense electrical currents that flow high in our atmosphere when auroras shimmer above Earth's poles......»»
International team decodes the genome of the Greenland shark
The Greenland Shark (Somniosus microcephalus), an elusive dweller of the depths of the northern Atlantic and the Arctic Ocean, is the world's longest-living vertebrate, with an estimated lifespan of about 400 years......»»
Precariously balanced rocks in New York, Vermont provide limits on earthquake shaking
Five boulders, delivered by glacier and balancing delicately on rocky pedestals in northern New York and Vermont, can help define long-term maximum shaking intensity of earthquakes in the region......»»
