Polar oceans pump organic carbon down to the deep sea about five times as efficiently as subtropical waters, because they can support larger, heavier organisms. The finding helps explain how the oceans may function under climate change.
Time to smash the beaker when thinking about oxygen concentrations in water, at the time when animal life first evolved. Oceans stacked O2 here and depleted it there, as this novel model demonstrates. It may well toss a wrench into the way we have dated the evolution of the earliest animals.
A very unusual new species of zoantharian surprised Drs Takuma Fujii and James Davis Reimer, affiliated with Kagoshima University and University of the Ryukyus.
Discovered by scientists using the manned submersible Curasub in the deep-reef waters of the Caribbean island of Curaçao, a new scorpionfish species is the latest one captured with the help of the sub's two robotic arms.
Dublin, Ireland, Tuesday July 19, 2016 - An international consensus demands human impacts on the environment "sustain", "maintain", "conserve", "protect", "safeguard", and "secure" it, keeping it within "safe ecological limits". But, a new Trinity College Dublin-led study that assembled an international team of environmental scientists shows that policy makers have little idea what these terms mean or how to connect them to a wealth of ecological data and ideas.
A University of Washington team has shed new light on a common but poorly understood bacteria known to live in low-oxygen areas in the ocean. By culturing and sequencing the microbe's entire genome, the oceanographers found that it significantly contributes to the removal of life-supporting nitrogen from the water in new and surprising ways.
A study of nearly 22,000 fossils finds that ancient plankton communities began changing in important ways as much as 400,000 years before massive die-offs ensued during one of Earth’s great mass extinctions. This turmoil, in a time of ancient climate change, could hold lessons for the modern world.
Researchers at Case Western Reserve University have combined tissues from a sea slug with flexible 3-D printed components to build “biohybrid” robots that manage different tasks than animals or purely manmade robots could.
Erosion, human activities challenge beach ecosystems
An international research team has calculated the costs and benefits of calcification for phytoplankton and the impact of climate change on their important role in the world’s oceans.
The largest island in the Philippines may be home to the greatest concentration of mammal diversity in the world, according to a research team that has been exploring the island for the past 15 years.
You'll never look at a drop of water the same way. By measuring a water droplet with a resolution comparable with the scale of a single atom, scientists have determined that the droplet interface behaves like a miniature stormy sea even when it appears to be at rest.
Imagine rolling your eyes to help you see more clearly. Although it wouldn't work for humans, new research published today in Nature Communications has shown mantis shrimp use eye rotations to enhance their polarization vision.
Europe will be spared the worst economic impacts of climate change by a slowing down of the Gulf Stream, new research predicts.
On Monday, July 18, members of the Combat Wounded Veteran Challenge and SCUBAnauts International will join forces with scientists from Mote Marine Laboratory to plant nursery-grown corals near Looe Key in the Florida Keys.
For the first time in New Zealand waters an extremely rare grouping of Shepherd's Beaked Whales has been spotted from a University of Otago research vessel off the coast of the city of Dunedin in the South Island.
Members of the Inter-American Tropical Tuna Commission (IATTC) must do more to follow through on critical commitments to protect tuna and shark populations in the eastern Pacific Ocean. The IATTC, the world’s oldest regional fishery management organization (RFMO) for tuna, meets June 27 to July 1 in La Jolla, California.
A new commentary in the peer-reviewed Marine Technology Society Journal is calling for some BP settlement dollars to support ocean tools that will aid in the collection of real-time data in the Gulf of Mexico.
A new study carried out on the floor of Pacific Ocean provides the most detailed view yet of how the earth's mantle flows beneath the ocean's tectonic plates. The findings, published in the journal Nature, appear to upend a common belief that the strongest deformation in the mantle is controlled by large-scale movement of the plates. Instead, the highest resolution imaging yet reveals smaller-scale processes at work that have more powerful effects.
The recent trend of increasing Antarctic sea ice extent — seemingly at odds with climate model projections — can largely be explained by a natural climate fluctuation, according to a new study led by the National Center for Atmospheric Research.
A variety of normally harmless bacteria can cause bleaching disease in seaweeds when the seaweeds become stressed by high water temperatures, UNSW Australia researchers have discovered.
New evidence shows that higher levels of iron oxides in ocean and coastal sediments speed the conversion of the more potent greenhouse gas methane into carbon dioxide even in the absence of oxygen.
University of Delaware researchers project that approximately 30 percent of current Adélie penguin colonies may be in decline by 2060 and approximately 60 percent may be in decline by 2099. The declines are associated with warming - many regions of Antarctica have warmed too much and further warming is no longer positive for the species.
A common close partnership which sees baby fish sheltering from predators among the poisonous tentacles of jellyfish will be harmed under predicted ocean acidification, a new University of Adelaide study has found.
Biologists from Queen Mary University of London (QMUL) have discovered that the evolutionary history of a hormone responsible for sexual maturity in humans is written in the genes of the humble starfish.
Before five shark attacks left four people dead and one wounded on the Jersey Shore in 1916, there was widespread doubt a shark would even bite a human.
Pipelines carrying crude oil to ports in British Columbia may spell bad news for salmon, according to a new University of Guelph-led study. Exposure to an oil sands product – diluted bitumen – impairs the swimming ability and changes the heart structures of young salmon.
Rising sea temperatures in the Mediterranean are encouraging alien lionfish species to invade and colonise new territories with potentially serious ecological and socioeconomic impacts.
Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study shows how that ice migration may be more important for the global ocean circulation than anyone realized.
The Gulf of Mexico Coastal Ocean Observing System Regional Association (GCOOS-RA) has been awarded $1.8 million a year for the next five years to support data collection and distribution in the Gulf of Mexico.
A new study by Simon Fraser University marine ecologists Jessica Schultz, Ryan Cloutier and Isabelle Côté has discovered that a mass mortality of sea stars resulted in a domino effect on B.C.'s West Coast Howe Sound marine ecology.
With the help of University of Alberta scientists, a newly described pterosaur has finally flown home. This spectacular fossil material was discovered in a private Lebanese limestone quarry more than a decade ago and has led to what UAlberta paleontologist Michael Caldwell calls “priceless scientific findings.”
A new study by UCSB evolutionary biologists Todd Oakley and Emily Ellis demonstrates that for fireflies, octopuses and other animals that choose mates via bioluminescent courtship, sexual selection increases the number of species -- thereby impacting global diversity. Their results appear in the journal Current Biology.
Fitbit-like sensors are the best tools for monitoring whether sharks survive catch-and-release fishing — essential data for fisheries management — according to a peer-reviewed study published June 23 by scientists from Mote Marine Laboratory.
Fish have evolved the ability to live on land many times, challenging the perception that this extreme lifestyle shift was likely to have been a rare occurrence in ancient times, new UNSW Australia research shows.
New research suggests that direct transmission of cancer among marine animals may be much more common than once thought.
A study of the Caribbean Sea by University of Liverpool ocean scientists has revealed that, in the midst of all the noise of the ocean, this region behaves like a whistle, which blows so loudly that it can be 'heard' from space in the form of oscillations of the Earth's gravity field.
An international team of scientists has developed a relatively simple mathematical explanation for the rogue ocean waves that can develop seemingly out of nowhere to sink ships and overwhelm oil platforms with walls of water as much as 25 meters high.
The mystery of why most of the most powerful lightning on Earth happens over the oceans isn't solved, but a few of the usual suspects are no longer in custody. It's possible the increased presence of salt in the atmosphere plays a role.
Animals can adapt to their environment through changes to their DNA, but more recently, research has shown that non-genetic components may be important, too.
Halfway between Hawaii and American Samoa lies a group of small islands and inlets. Among them is Palmyra Atoll, an almost 5-square-mile ring of coral.
– The Gulf of Mexico Alliance (Alliance) is pleased to announce Freeport-McMoRan Foundation and NOAA as the newest members of the Gulf Star public-private partnership. The announcements come during the 12th annual All Hands meeting of the regional organization held in Baton Rouge, Louisiana. Gulf Star is designed to increase the region’s strength by addressing issues that are important to government, academia, not-for-profits, and businesses. The partnership will support projects in the areas of healthy seafood, improved habitat conservation, higher quality water resources, increased natural resource stewardship, and improved strategies for land use planning.
Shells of California mussels collected from the Pacific Ocean off the coast of Washington in the 1970s are on average 32 percent thicker than modern specimens, according to a new study published by University of Chicago biologists.
A special issue of the academic journal Deep-sea Research II, published recently, is devoted to expanding understanding of the global issue of chemical munitions dumped at sea. The publication was edited by Margo Edwards, interim director of the University of Hawai'i at Mānoa's (UHM) Hawai'i Institute of Geophysics and Planetology, and Jacek Beldowski, Science for Peace and Security MODUM ("Towards the Monitoring of Dumped Munitions Threat") project director at the Polish Academy of Sciences--two international leaders in the assessment of sea-dumped military munitions and chemical warfare; and the effects on the ocean environment and those who use it.
A 3-inch monogamous hermaphrodite proves the saying “there’s plenty more fish in the sea” isn’t always the case.
A study appearing in the journal PLOS ONE this week shows that bioluminescence -- the production of light from a living organism -- is more widespread among marine fishes than previously understood.
The New England Aquarium is celebrating the launch of its new Anderson Cabot Center for Ocean Life in Boston, a scientific institute focusing on fisheries conservation and aquaculture solutions, marine mammal research and conservation, habitat and ecosystem health, and marine animal health – a major new initiative for the Aquarium.
