Bulk sediment nitrogen isotopes from IODP Site 323-U1343 Holes A, C, and E

High latitude deep water upwelling has the potential to control global climate over glacial timescales through the biological pump and ocean-atmosphere CO2 exchange. However, there is currently a lack of continuous long nutrient upwelling records with which to assess this mechanism. Therefore, this...

Description
Summary:High latitude deep water upwelling has the potential to control global climate over glacial timescales through the biological pump and ocean-atmosphere CO2 exchange. However, there is currently a lack of continuous long nutrient upwelling records with which to assess this mechanism. Therefore, this study presents bulk nitrogen isotope data from IODP Site U1343 in the Bering Sea, a high productivity site located in a deep water upwelling region, over the last 850, 000 years. In conjunction with other geochemical data from the same site, this proxy records investigated productivity and nutrient upwelling dynamics in relation to the global carbon cycle.
