New 13-Year Study Tracks Effects Of Changing Ocean Temperature On Phytoplankton

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.

Robotic Mussels Track Rising Temperatures for Climate Research

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.
