Slime travelers
New UC Riverside-led research settles a longstanding debate about whether the most ancient animal communities were deliberately mobile. It turns out they were, because they were hungry. (2019-06-20)

Marine oil snow
Marine snow is the phenomena of flakes of falling organic material and biological debris cascading down a water column like snowflakes. But an oil spill like Deepwater Horizon will add oil and dispersants to the mix, making marine oil snow that is can be toxic to organisms in deep-sea ecosystems. (2019-06-11)

Sudden aging
Coralline red algae have existed for 130 million years, in other words since the Cretaceous Period, the time of the dinosaurs. At least this was the established view of palaeontologists all over the world until now. However, this classification will now have to be revised after fossils discovered by researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg in conjunction with researchers at La Trobe University in Melbourne prove that coralline red algae existed as far back as 430 million years ago. (2019-01-16)

Glaciers accelerate in the Getz region of West Antarctica
Glaciers in West Antarctica are moving more quickly from land into the ocean, contributing to rising global sea levels. A 25-year record of satellite observations has been used to show widespread increases in ice speed across the Getz sector for the first time, with some ice accelerating into the ocean by nearly 50%. (2021-02-23)

Methods and models
It's a well-known fact that the ocean is one of the biggest absorbers of the carbon dioxide emitted by way of human activity. What's less well known is how the ocean's processes for absorbing that carbon change over time, and how they might affect its ability to buffer climate change. (2019-06-19)

Doubling down
Over the recent decade, total human impacts to the world's oceans have, on average, nearly doubled and could double again in the next decade without adequate action. That's according to a new study by researchers from the National Center for Ecological Analysis and Synthesis (NCEAS) at UC Santa Barbara. (2019-08-13)

The heat is on
Climate change is reorganizing the life in our oceans in a big way: as waters warm, cold-loving species, from plankton to fish, leave the area and warm water species become more successful. So say an international group of scientists in the most comprehensive assessment of the effects of ocean warming on the distribution fish communities. (2019-11-25)

Alaska thunderstorms may triple with climate change
Warming temperatures will potentially alter the climate in Alaska so profoundly later this century that the number of thunderstorms will triple, increasing the risks of widespread flash flooding, landslides, and lightning-induced wildfires, new research finds. (2021-02-23)

(2018-11-27)

The long memory of the Pacific Ocean
Cold waters that sank in polar regions hundreds of years ago during the Little Ice Age are still impacting deep Pacific Ocean temperature trends. While the deep Pacific temperature trends are small, they represent a large amount of energy in the Earth system. (2019-01-04)

Arctic sea ice thinning at record rate
The thickness of sea ice in large parts of the Arctic declined by as much as 19 percent last winter compared to the previous five winters, according to data from ESA's Envisat satellite. (2008-10-28)

Team discovers a significant role for nitrate in the Arctic landscape
Because of the very low nitrate levels found in arctic tundra soil, scientists had assumed that plants in this biome do not use nitrate. But a new study co-authored by four Marine Biological Laboratory (MBL) Ecosystems Center scientists challenges this notion. The study has important implications for predicting which arctic plant species will dominate as the climate warms, as well as how much carbon tundra ecosystems can store. (2018-03-23)

How seafloor weathering drives the slow carbon cycle
A previously unknown connection between geological atmospheric carbon dioxide cycles and the fluctuating capacity of the ocean crust to store carbon dioxide has been uncovered by two geoscientists from the University of Sydney. Better understanding of the slow carbon cycle will help us predict to what extent the continents, oceans and ocean crust will take up the extra human-induced rise in atmospheric carbon dioxide in the long run. (2018-02-14)

Reconstruction of major North Atlantic circulation system shows weakening
Rising levels of carbon dioxide in the atmosphere have affected one of the global ocean's major circulation systems, the Atlantic Meridional Overturning Circulation (AMOC), slowing the redistribution of heat in the North Atlantic Ocean. The resulting changes have been felt along the Northeast US Shelf and in the Gulf of Maine, which has warmed 99 percent faster than the global ocean over the past ten years, impacting distributions of fish and other species and their prey. (2018-04-11)

Tropical Depression 11E 'born' with wind shear on satellite imagery
The eleventh tropical depression of the Eastern Pacific Ocean hurricane season came together on August 4 even though it was being affected by vertical wind shear. (2017-08-04)

Study: Much of the surface ocean will shift in color by end of 21st century
Climate change is causing significant changes to phytoplankton in the world's oceans, and a new MIT study finds that over the coming decades these changes will affect the ocean's color, intensifying its blue regions and its green ones. Satellites should detect these changes in hue, providing early warning of wide-scale changes to marine ecosystems. (2019-02-04)

Paleogenomics -- the prehistory of modern dogs
An international team of scientists has used ancient DNA samples to elucidate the population history of dogs. The results show that dogs had already diverged into at least five distinct lineages by about 11,000 years ago and that their early population history only partially reflects that of human groups. (2020-11-06)

Kidnapping in the Antarctic animal world?
Pteropods or sea snails, also called sea angels, produce chemical deterrents to ward off predators, and some species of amphipods take advantage of this by carrying pteropods piggyback to gain protection from their voracious predators. (2018-09-10)

Diverse and abundant megafauna documented at new Atlantic US Marine National Monument

UCI-led study: Plankton are more resilient to nutrient stress than previously thought
Surface ocean phosphate is a key mineral supporting the growth and diversification of phytoplankton, a marine organism the absorbs significant amounts of carbon dioxide from Earth's atmosphere. A University of California, Irvine-led team has used highly sensitive measurements to create a map of the global distribution of surface phosphate, finding regional differences and ultimately learning that plankton are a lot more resilient to nutrient-stress than previously thought. (2019-08-28)

How a 'shadow zone' traps the world's oldest ocean water
New research from an international team has revealed why the oldest water in the ocean in the North Pacific has remained trapped in a shadow zone around 2km below the sea surface for over 1000 years. (2017-11-10)

From rocks in Colorado, evidence of a 'chaotic solar system'
Plumbing a 90 million-year-old layer cake of sedimentary rock in Colorado, a team of scientists from the University of Wisconsin-Madison and Northwestern University has found evidence confirming a critical theory of how the planets in our solar system behave in their orbits around the sun. The finding, published Feb. 23, 2017 in the journal Nature, is important because it provides the first hard proof for what scientists call the ''chaotic solar system.' (2017-02-22)

Sea floor uplift after last ice age causes methane release in the Arctic today
Present-day release of methane from an area of the Arctic Ocean is an effect of the uplift of the sea floor, rather than anthropogenic ocean warming, a new study in Nature Communications states. (2018-02-06)

Ocean acidification 'could have consequences for millions'
Ocean acidification could have serious consequences for the millions of people globally whose lives depend on coastal protection, fisheries and aquaculture, a new publication suggests. (2019-04-26)

The critical importance of mangroves to ocean life
Mangrove plants, whose finger-like roots are known to protect coastal wetlands against the ocean and as important fish habitats, cover less than 0.1 percent of the global land surface yet account for a tenth of the dissolved organic carbon (DOC) that flows from land to the ocean. The plants are one of the main sources of dissolved organic matter in the ocean. (2006-02-27)

Unraveling a major cause of sea ice retreat in the Arctic Ocean
Quantitative analysis has evidenced the acceleration system of melting ice: dark water surfaces absorb more heat than white ice surfaces, thus melting ice and making more water surfaces in the Arctic Ocean. (2017-09-06)

Molting bowhead whales likely rub on rocks to facilitate sloughing off skin
Bowhead whales molt and rub on large rocks -- likely facilitating exfoliation -- in coastal waters in the eastern Canadian Arctic during late summer, according to a study published Nov. 22, 2017, in the open-access journal PLOS ONE by Sarah Fortune from University of British Columbia, Canada, and colleagues. (2017-11-22)

Update on the Larsen-C iceberg breakaway
Since an iceberg four times the size of London broke free earlier this month, scientists have continued to track its progress using satellites. Their observations show the Larsen-C story might not be over yet. (2017-08-02)

Ocean winds influence seal pup migration
Scientists have confirmed what native Alaskans have observed for centuries -- maritime winds influence the travel patterns of northern fur seal pups. New research presented at the Ocean Sciences Meeting here today shows strong winds can potentially displace seal pups by hundreds of kilometers during their first winter migration. (2018-02-13)

The astounding genome of the dinoflagellate
Dinoflagellates live free-floating in the ocean or symbiotically with corals, serving up -- or as -- lunch to a host of mollusks, tiny fish and coral species. But when conditions are wrong, dinoflagellates poison shellfish beds with red tides and abandon coral reefs to a slow, bleached death. Globally, this is happening more and more often. Seeking answers, a team of researchers sequenced the complete genome of a dinoflagellate species for the first time. (2015-11-05)

Ocean floor geysers warm flowing sea water
An international team of earth scientists report movement of warmed sea water through the flat, Pacific Ocean floor off Costa Rica. The movement is greater than that off midocean volcanic ridges. The finding suggests possible marine life in a part of the ocean once considered barren. (2008-09-22)

Arctic wintertime sea ice extent is among lowest on record
Sea ice in the Arctic grew to its annual maximum extent last week, and joined 2015, 2016 and 2017 as the four lowest maximum extents on record, according to scientists at the NASA-supported National Snow and Ice Data Center (NSIDC) and NASA. (2018-03-23)
