Dissolved chloride measurements of marine sediment from Long Core Expedition KN195-03

Resource Abstract:
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 throughout the collected cores is fundamental
to answer the driving research questions of this scientific expedition. The shipboard geochemistry laboratory generated interstitial
waters by squeezing 597 individual samples, and by extracting an additional 153 solutions by Rhizon sampling. Due to the time
needed to analyze this very high number of samples, not all were analyzed for each dissolved constituent. We present here
the shipboard porewater chloride concentration dataset measured by ion chromatography.
