Surface total dissolvable iron data collected during an August 2015 cruise to Sermilik Fjord, East Greenland

This dataset contains discrete total dissolvable iron (TdFe) data collected from the surface of Sermilik Fjord in SE Greenland in August 2015 aboard the RV Adolf Jensen. Surface samples were collected using a trace metal clean sampler fixed to a plastic pole. Samples were taken while the ship was steaming at approximately 1 knot in order to minimize contamination from the ship. All bottles and plasticware were cleaned using trace metal clean procedures outlined in the U.S. GEOTRACES protocols. Unfiltered samples were placed in separate trace metal clean 250 mL low-density polyethylene bottles and immediately acidified to pH 1.8 with 4 mL Optima HCl (Fisher Scientific) and stored until analysis using standard addition methods and cathodic stripping voltammetry 4 months later in the lab at the Woods Hole Oceanographic Institution.
