The samples were collected at sea into poisoned, pre-evacuated bottles and then measured on an isotope ratio mass spectrometer. The gas data was then used to calculate mixed layer depth integrated rates of gross primary production (in oxygen units = gross oxygen production) and net community production. The gas data itself is posted on BCO-DMO in the bottle CTD tables associated with this cruise. This data set contains the rates of production calculated from the gas data for those who simply want the rates rather than the gas data.  This data set has rates calculated from samples collected from cruises on the US Northeastern Shelf taking place in Spring 2018 (Ar29), spring 2019 (RB1904) and summer 2019 (TN368). There is no depth associated with each rate since the exact depth the water came from does not matter - the rate represents the production integrated over the mixed layer in all cases and the depth of collection is not the same as the mixed layer depth. CTD data posted on BCO-DMO can be used to determine depths if desired and/or mixed layer depths.\n\ncdm_data_type = Other\nVARIABLES:\nCruise (unitless)\ntime (Date_time, seconds since 1970-01-01T00:00:00Z)\nlatitude (degrees_north)\nlongitude (degrees_east)\nGOP (mmol O2/m2/day)\nNCP (mmol O2/m2/day)\nNCP_GOP (unitless)\n https://erddap.bco-dmo.org/erddap/metadata/fgdc/xml/bcodmo_dataset_985985_v1_fgdc.xml https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_985985_v1_iso19115.xml https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_985985_v1/index.htmlTable https://osprey.bco-dmo.org/dataset/985985 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_985985_v1.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_985985_v1&showErrors=false&email= BCO-DMO bcodmo_dataset_985985_v1
