attribute	NC_GLOBAL	summary	String	Beryllium-7 (Be-7) is a radioactive isotope with a half-life of 53.3 days. It is formed in the atmosphere, attaches to aerosol particles, and is subsequently deposited to the Earth's surface by wet and dry deposition processes. As part of the GEOTRACES GP17-ANT project, we measured Be-7 concentrations in surface ocean seawater (depths <200 meters) samples collected from six stations and bulk aerosol particles collected across eight deployments in the Southern Ocean and Amundsen Sea region. Samples were collected aboard the research vessel ice breaker Nathaniel B. Palmer during cruise NBP2401 (29 November 2023 to 28 January 2024). The dataset will be used to calculate bulk atmospheric deposition velocities across the study region, based on the premise that Be-7 inventory in the surface ocean is controlled primarily by atmospheric deposition and radioactive decay. Thus, from the surface Be-7 inventory, its deposition flux can be determined, and from that and the aerosol Be-7 concentration, we can determine deposition velocity. The determined deposition velocity will then be used with aerosol concentrations of trace elements measured during the same study to determine rates of atmospheric supply of trace elements to the region.
