Coral reefs around the globe already are facing unprecedented damage because of warmer and more acidic oceans. It’s hardly a problem affecting just the marine life that depends on them or deep-sea divers who visit them.
A new multiyear study from scientists at the Woods Hole Oceanographic Institution (WHOI) has shown for the first time how changes in ocean temperature affect a key species of phytoplankton. The study, published in the October 21 issue of the journal Science, tracked levels of Synechococcus -- a tiny bacterium common in marine ecosystems -- near the coast of Massachusetts over a 13-year period. As ocean temperatures increased during that time, annual blooms of Synechococcus occurred up to four weeks earlier than usual because cells divided faster in warmer conditions, the study found.
If you were to stare down into one of a few dozen intertidal pools at low tide, as waves glide in and out, you might have a hard time spotting the robots. That’s because they look just like the real mussels that surround them. “It’s a problem finding them again,” said Brian Helmuth, a professor of marine science and public policy at Northeastern University, “because they do look so much like mussels.”The robotic mussels, which were devised about 18 years ago by Dr. Helmuth, contain little thermometers and data loggers that record the temperature every 10 minutes, approximating the internal temperature of the actual mussels nearby.
The appearance of white blooms of plankton east of New Zealand suggests the ocean is responding to climate change, according to research by Victoria University of Wellington scientists.
New research, led by the University of Southampton, has found that human activities such as shipping are having a noticeable impact on marine species and their native habitats.
SARASOTA, Fla. - Mote Marine Senior Scientist Dr. Kevan Main was among those honored on Friday at the White House. Dr. Main is head of the lab's aquaculture park in Eastern Sarasota County.
A new study finds that unusually warm Pacific Ocean temperatures helped cause a massive bloom of toxic algae last year that closed lucrative fisheries from California to British Columbia and disrupted marine life from seabirds to sea lions.
A new study of lead pollution in the North Atlantic provides strong evidence that leaded petrol emissions have declined over the past few decades.
An international research team has tripled the number of known types of viruses living in waters worldwide, which they say could help scientists understand the role viruses play in nature and how they can "bolster efforts to curb greenhouse gasses."
A new mathematical model developed at the University of British Columbia integrates environmental and molecular sequence information to better explain how microbial networks drive nutrient and energy cycling in marine ecosystems.
Ocean temperatures have been consistently rising for at least three decades. Scientists believe that global sea surface temperatures will continue to increase over the next decade as greenhouse gases build up in the atmosphere.
