Rising acid in oceans is worsening industry toxins
Acidification of UK waters may make industrially-contaminated sediments more toxic over time, say scientists.
Shimmering water reveals cold volcanic vent in Antarctic waters
The location of an underwater volcanic vent, marked by a low-lying plume of shimmering water, has been revealed by scientists at the National Oceanography Centre, Southampton.
How do corals survive in the hottest reefs on the planet?
Coral reefs are predicted to decline under the pressure of global warming. However, a number of coral species can survive at seawater temperatures even higher than predicted for the tropics during the next ...
New research shows some barnacles mate via spermcasting
The effect of stress on Atlantic salmon's congenital immunity to IPN
Stress affects the congenital immune defence system. New doctoral research has revealed how stress can lower the immunity of salmon and increase its susceptibility to viral infection.
New study challenges old views about evolution of early life
A research team led by biogeochemists at the University of California, Riverside has tested a popular hypothesis in paleo-ocean chemistry, and proved it false.
Analysis of Marcellus flowback finds high levels of ancient brines
Brine water that flows back from gas wells in the Marcellus Shale region after hydraulic fracturing is many times more salty than seawater, with high contents of various elements, including radium and barium. The chemistry ...
Investigating ocean currents using uranium-236 from the 1960s
Stephan Winkler, isotope researcher at the University of Vienna, has identified the bomb-pulse of uranium-236 in corals from the Caribbean Sea for the first time. 236U was distributed world-wide in the period ...
Scientists probe Canadian sulfide ore to confirm microbial activity in seawater 2.7 billion years ago
An analysis of sulfide ore deposits from one of the world's richest base-metal mines confirms that oxygen levels were extremely low on Earth 2.7 billion years ago, but also shows that microbes were actively ...
A 3.45-billion-year-old diet
Researchers are providing new information about the 'diet' of microorganisms on the early Earth. By studying 3.45-billion-year-old rocks, the team uncovered clues about ancient microbial metabolism.
Antimicrobial resistance in fish pathogenic bacteria and other bacteria in aquatic environments
Little attention has been paid to the use of antibiotics in the aquaculture industry as one reason for the increase in bacteria resistant to antibiotics and the spread of such resistance to other bacteria.
Darkened fjord waters mean fewer fish, more jellyfish
The seawater in the Baltic Sea, the North Sea, and Norway's coastal waters and fjords is gradually getting darker. Researchers are observing signs similar to those from overproduction of organic compounds. ...
Sitting still or going hunting: Which works better?
For the kinds of animals that are most familiar to us—ones that are big enough to see—it's a no-brainer: Is it better to sit around and wait for food to come to you, or to move around and find it? Larger ...
Live cables explain enigmatic electric currents
Researchers at Aarhus University, Denmark, made a sensational discovery almost three years ago when they measured electric currents in the seabed. It was unclear as to what was conducting the current, but ...
