A data repository for: Seasonal variability of surface ocean carbon uptake and chlorophyll-a concentration in the West Antarctic Peninsula over two decades

This data repository is a permanent archive of the results presented in the associated publication (Turner et al. 2025, Geophysical Research Letters, https://doi.org/10.1029/2024GL112446). The objective of this study was to investigate seasonal patterns in surface ocean CO2 uptake and phytoplankton biomass in the Drake Passage and west of the Antarctic Peninsula using underway in situ data from research vessels and satellite ocean color remote sensing data. This dataset extends from 80oW to 55oW longitude and from 70oS to 57oS latitude. The data span the time period  July 1, 2000 through June 30, 2020. This dataset includes the data and code used to create the figures in the publication. The ship-based data in this repository include air-sea CO2 flux (delta-pCO2) calculated as pCO2-surface ocean minus pCO2-atmosphere, surface ocean partial pressure of CO2 (pCO2sur), and sea surface temperature (SST). The satellite-derived data in this repository include chlorophyll-a concentration (Chl-a). Ship-based data are included as .csv files. Downloaded spatially-subsetted satellite-derived data files are included as netCDF files (extension .nc). Additional files used to perform the analyses and make the figures are included as MATLAB scripts and MATLAB data files (extensions .m and .mat, respectively).
