Profound changes in concentrations of phytoplankton biomass and rates of primary production in warm-core Gulf Stream rings can occur, apparently in response to nutrient enrichment, within a few months after a ring separates from the Gulf Stream. In Ring 8 1 -D at 3 months of age the dependence on NO,was 2%3 times as high as in the northern Sargasso Sea and(More)
Marine mammals have recently been documented as important facilitators of rapid and efficient nutrient recycling in coastal and offshore waters. Whales enhance phytoplankton nutrition by releasing fecal plumes near the surface after feeding and by migrating from highly productive, high-latitude feeding areas to low-latitude nutrient-poor calving areas.
