Bulk sediment calcium concentration from Long Core Expedition KN195-03

The KN195-03 research cruise on board the R/V Knorr (Chief scientist Steven D’Hondt) took place in January-February 2009 and had as primary objective to test and refine quantitative models for the magnitude and geographic distribution of subseafloor biomass and organic-fueled subseafloor respiration. Sediment cores were taken at thirteen sites across the equatorial Pacific and the North Pacific Gyre. Knowledge of the chemical composition of the porewater and bulk sediment chemistry throughout the collected cores is fundamental to answer the driving research questions of this scientific expedition. We present here the bulk sediment calcium concentration data set measured by inductively coupled plasma mass spectrometry (ICP-MS) in the Murray lab at Boston University, MA.
