Scripps research gives tiny phytoplankton a large role in Earth's climate system
...1 to 0.6 degrees Fahrenheit (compared with an open seawater scenario without phytoplankton). "Our paper shows that if we did not have phytoplankton in the ocean, we would have a cooler climate. This is a problem that we have to look at more carefully if we want to conduct more accurate predictions of climate ......Lab. "When methane, which is a gas, combines with seawater to make methane hydrate, it rejects the salt in the water. Therefore, fresh water is produced when the concentrated hydrates are melted. It's a desalination process where the methane can be recycled to continue the process. For areas thirsty for w...Using the ocean's living light shows to fight terrorism or track the planet's most massive migration
... This is a light-tight chamber that rapidly draws seawater in past a wide mesh screen measuring the light given off by the organisms present. Bioluminescent animals are stimulated to give off light by just about any agitation, so they glow either when hitting the mesh, or due to the motion of water passing t...Asian dust storm causes plankton to bloom in the North Pacific
...wer than in other regions. By dissolving carbon in seawater and by fixing it as biomass or inorganic particulate matter, phytoplankton regulates carbon dioxide in the atmosphere and thus helps regulate global climate.

While dense plumes of volcanic ash were found throughout the water column down to >1000 m, the samples were almost devoid of volcanic tracers such as helium and dissolved metals. These...The seawater in the Waddenzee is becoming fresher. More river water is reaching the Waddenzee via the outlet sluices of the IJsselmeer Dam.
