Water column phosphate data from R/V Atlantic Explorer AE1812, May 2018 (NCEI Accession 0277821)
This dataset contains chemical data collected on R/V Atlantic Explorer during cruise AE1812 from 2018-05-02 to 2018-05-15. These data include depth and reactive phosphorus (PO4). The instruments used to collect these data include CTD profiler, Centrifuge, Niskin bottle, Sediment Trap - Particle Interceptor, Shipboard Incubator, and Spectrophotometer. These data were collected by Dr Tatiana Rynearson of University of Rhode Island and Dr Benjamin A.S. Van Mooy of Woods Hole Oceanographic Institution as part of the "Collaborative Research: Defining the biogeochemical drivers of diatom physiological ecology in the North Atlantic (North Atlantic Diatoms)" and "Redox Cycling of Phosphorus in the Western North Atlantic Ocean (Phosphorus Redox Cycling)" projects. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-04-10.

Supplemental Information | Acquisition Description: MAGIC Soluble reactive phosphorus (SRP) concentrations. SRP (i.e. phosphate) was determined in seawater samples (done in triplicate) and incubations using MAGnesium Induced Coprecipitation (MAGIC) as described by Karl and Tien (1992). Total particulate phosphorus (TTP) concentrations. TPP was determined in seawater samples using a wet chemical oxidation method using potassium persulfate as described in Suzumura (2008). Briefly, 1 to 2 liters of seawater were filtered onto 47 mm 0.2 µm pore size polyvinylidene fluoride membranes (Millipore) and frozen (-80°C) until analysis. One fourth of these filters were cut with clean stainless-steel scissors and placed in 8 mL glass vials for oxidation. 2 mL of 5% (0.19 M) persulfate was added to each vial and the samples were then autoclaved for 30 minutes at 120°C. To remove any residual material, the samples were filtered through 0.45 µm syringe filters (Millipore Millex-HV). The persulfate was shown to inhibit color development when greater than 2%, therefore, the samples were diluted to 0.5% (0.019 M). As with the SRP samples, the TPP samples were analyzed via the molybdenum blue method using a spectrophotometer (Thermo). |
