attribute NC_GLOBAL summary String An at-sea equilibrator inlet mass spectrometer was used onboard  three cruises in 2018 and 2019 in the Northeastern US Shelf as part of the SPIROPA project in order to measure ratios of O2/Ar in the underway water. The gas ratios were used to calculate rates of net community production at kilometer scale resolution. This dataset thus contains the gas ratios as well as the calculated rates. The data was collected on the R/V Armstrong from 4/16/18 to 4/29/18, on the NOAA ship Ron Brown from 5/12/2019 to 5/25/2019 and on the R/V Thompson from 7/5/2019 to 7/17/2019.  This high spatial resolution data enables us to see submesoscale variability in rates of net community production and to assess whether changes in rates of NCP are co-located with physical processes. This dataset also contains necessary metadata such as location and time as well as useful data from shipboard CTD sensors such as temperature and salinity. Gas transfer rates are required to calculate rates of NCP from gas tracer data. The data includes the gas transfer rates that were used in the calculations, which were determined from NCEP reanalysis winds, a 60 day weighting scheme, and the gas exchange parameterization of Stanley et al., 2009. NCP was calculated based on mass balance with typical assumptions of steady state and negligible vertical and horizontal mixing.  Details on how NCP rates were calculated from the O2/Ar data are available in Stanley et al. (in press at L&O) and Castillo Cieza et al (2024).
