Description

Particulate organic carbon and nitrogen measurements from CTD casts in the Monterey Bay area on RV/Point Sur cruise PS1312, June-July 2013

Methods & Sampling

Dataset acquisition description

Whole seawater was collected using Niskin bottles mounted on a CTD rosette. Water was filtered onto 25 mm pre-combusted GF/F filters, flash frozen in liquid nitrogen, and stored at -80C until analysis. Prior to analysis, samples were thawed and dried overnight at 60C. Filters were acidified in a glass desiccator with concentrated HCl overnight, then dried again for at least 24 h. Samples were then run on a CHN Elemental Analyzer.

Milligrams of particulate organic carbon and nitrogen were determined according to standard measurements. The carbon and nitrogen content (mg) was then converted to a molar content (micromol) and divided by the volume of seawater filtered.
