HLY-07-01 Nitrogen Productivity and Supply

This data collection consists of measurements made on particles filtered from seawater during cruise 0701 of the US Coast Guard Cutter Healy during the first cruise of the Bering Sea Ecosystem Study-Bering Sea Integrated Ecosystem Research Program (BEST-BSIERP) which together are the Bering Sea project.. This project is measuring new (nitrate) and regenerated nitrogen production directly with tracer incubation measurements in ice-impacted and ice-free regions of the eastern Bering Sea. Measurements of particulate organic carbon (POC) and particulate nitrogen (PN), as well as nitrate and ammonium productivity (NO3 & NH4) were made using an ANCA elemental combustion unit and a Europa 20-20 mass spectrometer at Lamont-Doherty.
