Global Change Expedition: Nutrient, chlorophyll-a, and primary productivity data, NOAA Ship Mt. Mitchell, July 14-September 6, 1988. Nutrient, chlorophyll-A and primary productivity data, NOAA ship Mt. Mitchell, 14 July-6 September 1988

During the period of 14 July-6 September 1988, a multifaceted oceanographic research cruise called the Global Change Expedition was made on the NOAA Ship <em>Mt. Mitchell</em> in the North Atlantic Ocean. The objective of the cruise was to study the atmospheric and oceanic processes affecting the biogeochemical cycles of carbon, nitrogen, sulfur, and trace metals. Emphasis was made on compounds of these elements that would influence the radiation balance of the earth and, hence, of global climate. Measurements from hydrocasts for nutrients, phytoplankton biomass, and productivity were made on a daily basis during the period. The report represents the biological and chemical (nutrient) data from the cruise.
