Beyond colorful coral reefs and diverse nearshore ecosystems, the Pacific Ocean waters surrounding the Hawaiian Islands have comparatively little marine life and low biological productivity. New research published by University of Hawai'i (UH) at Mānoa oceanographers showed that eddies on the leeward side of the Hawaiian Islands can supply nutrients, not only locally, but also to the opposite side of the island chain and stimulate blooms of phytoplankton, microscopic plant life that lives in the surface ocean.
