Abstract:

Biogeochemical parameters collected on RRS Discovery cruise DY080 in June 2017 through two mid-high latitude North Atlantic eddies. Includes macronutrient concentrations, dissolved iron and dissolved manganese, phytoplankton chlorophyll-a, particulate organic carbon and nitrogen, biogenic silicate, flow cytometry cell counts, temperature and salinity.
