Nutrients, chlorophyll-a, and light attenuation in the Delaware estuary from the R/V Hugh R. Sharp HRS110805DK, HRS111107DK, HRS120809DK, HRS121112DK, HRS1313, HRS1324 in 2011 - 2013 (PAPI: Photochemistry and Photoheterotroph Interactions project) (NCEI Accession 0278184)
This dataset contains biological and chemical data collected on R/V Hugh R. Sharp during cruises HRS110805DK, HRS111107DK, HRS120809DK, HRS121112DK, HRS1313, and HRS1324 from 2011-08-05 to 2013-11-21. These data include Ammonium, Nitrate, Silicate, chlorophyll a, and reactive phosphorus (PO4). The instruments used to collect these data include Fluorometer and Nutrient Autoanalyzer. These data were collected by David J. Kieber of State University of New York ESF and Dr David L Kirchman of University of Delaware as part of the "Activity and abundance of photoheterotrophs fueled by photochemically-produced substrates (PAPI: Photochemistry and Photoheterotroph Interactions)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-10-01.

Supplemental Information | Acquisition Description: Nutrient concentrations were measured by standard wet chemical methods using a SEAL Analytical AA3 Continuous Segmented Flow Analyzer. Samples for chlorophyll a concentrations were collected by filtering 100 ml of estuarine water through Whatman GF/F filters and stored at -20 o C until analysis. To estimate concentrations, the filters were placed into 90% acetone and 40% dimethyl sulfoxide ( DMSO ) and then the fluorescence in the extract was measured with a Turner Designs 10-AU fluorometer. The attenuation coefficient was estimated by measuring photosynthetically active radiance with a Biospherical PNF-210 radiometer over a depth profile. In nearly all cases, the downcast and upcast profiles of radiance were indistinguishable and all data were used. When differences between the down and upcasts were apparent, only the downcast data were used. |
