Iron in Northwest rivers fuels phytoplankton, fish populations

The study, by three Oregon State University oceanographers, was just published by the American Geophysical Union in its journal, Geophysical Research Letters.West coast scientists have observed that ocean chlorophyll levels, phytoplankton production and fish populations generally increase in the Pacific Ocean the farther north you go (from southern California to northern Washington). No one has a definitive explanation for the increase, the OSU scientists say, though some researchers have suspected river runoff may play a role. That theory has generally been discounted, they added, because river flows are low in the summer when phytoplankton blooms occur….

New evidence that global warming fuels stronger Atlantic hurricanes

The unsettling trend is confined to the Atlantic, however, and does not hold up in any of the world's other oceans, researchers have also found. Scientists at…

Scripps Oceanography Research Studies Shed New Light on Blue Whales and Their Calls

CSIRO imagery shows outer Great Barrier Reef at risk from river plumes

The remotely sensed images, taken from February 9 to 13 this year, challenge conventional thought that sediment travelling from our river systems into the GBR…

A climate-change amplifying mechanism

With the help of paleoclimatic and paleooceanographic indicators, scientists at CEREGE1 have highlighted a feedback mechanism of ocean circulation on the…

Mistaken identity? When a white marlin may not always be a white marlin

For years, anglers thinking they were catching the prized white marlin may have caught something quite different, raising concerns about the true remaining…
