Chlorophyll a concentrations measured along the cruise track of AE1812 which transected from the Sargasso Sea to Coastal Rhode Island during May 2018 (NCEI Accession 0278049)
This dataset contains biological and optical data collected on R/V Atlantic Explorer during cruise AE1812 from 2018-05-02 to 2018-05-15. These data include chlorophyll a, depth, fluorescence, and total phaeopigment. The instruments used to collect these data include Turner Designs Fluorometer 10-AU. These data were collected by Bethany D. Jenkins and Tatiana Rynearson of University of Rhode Island as part of the "Collaborative Research: Defining the biogeochemical drivers of diatom physiological ecology in the North Atlantic (North Atlantic Diatoms)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-08-26.
The following is the text of the dataset description provided by BCO-DMO:
Acquisition Description:
In situ Chlorophyll a was measured at each station along the AE1812 cruise track. A CTD was deployed to collect water from the euphotic zone. Samples were filtered in triplicate onto GF/F and 5µm and 20µm polycarbonate filters.
Chl a was extracted from filters in 100% denatured ethanol for 12 hours, measured on a 10-AU Fluorometer, and chlorophyll a and phaeophytin concentrations were calculated based on a predetermined calibration curve. Concentrations on each filter were used to determine total chl a within each size fraction.
