Published by geoff on 2013-12-21 The North Pacific subtropical gyre (NPSG) is a major source of carbon and other nutrients to the deep ocean. Primary production in the NPSG has increased in recent decades due to a shift in the dominant forms of plankton to nitrogen-fixing. As a proxy for nitrogen-supported nutrient production in the […] Read More
