Two-minute averaged net community production in seawater estimated along the Antarctic Circumnavigation Expedition during the austral summer of 2016/2017.

<strong>Dataset abstract</strong> During the Antarctic Circumnavigation Expedition (ACE) in the austral summer of 2016/2017, seawater O2/Ar ratios were measured underway from the ship's flow-through seawater system. High-resolution net community production (NCP) in units of mmol O2 m-2 day-1 was derived from delta O2/Ar and National Centers for Environmental Prediction (NCEP) reanalysis winds followed by a linear correction for sea-ice. <strong>Dataset contents</strong> ace_ncp_linear_correction.csv, data file, comma-separated values data_file_header.txt, metadata, text README.txt, metadata, text change_log.txt, metadata, text <strong>Change log</strong> v1.1 - data reprocessed using different version of sea ice. data file reprocessed README updated to reflect change in processing change log added to dataset v1.0 - initial release of dataset
