High-resolution vertical nitrate profiles from the CTD rosette-mounted submersible ultraviolet nitrate analyzer over the Northeast U.S. Shelf since February 2019 (NCEI Accession 0297573)
This dataset contains high-quality high-resolution nitrate data collected from a submersible ultraviolet nitrate analyzer (SUNA) mounted on the CTD rosette. Both raw and bias-corrected, quality-controlled data are included. The raw data include the instrument's estimate of nitrate concentration with dark values and light intensity at 256 wavelengths. Our quality-controlled SUNA nitrate data have an accuracy of 0.34-0.78 micromoles per liter, with a precision of 0.08-0.21 micromoles per liter, at a vertical resolution of 1 m. These data are collected from about 21 routinely occupied stations along a cross-shelf transect spanning southward from Martha's Vineyard, MA to just beyond the shelf break onboard the seasonal Northeast U.S. Shelf Long-Term Ecological Research (NES-LTER) survey cruises since February 2019. Data in CSV format.
