Abstract

The dataset is a permanent archive of the results presented in the associated publication (St-Laurent et al. 2020, Biogeosciences).

This study used a biogeochemical module embedded in the Regional Ocean Modeling System (ROMS) to examine the relative impacts of global changes and regional watershed changes on the inorganic carbon balance of the Chesapeake Bay over the past century. The numerical experiments contrast the periods 1900-1914 and 2000-2014 and the results are fully described in the associated publication.

Description

This dataset features the results from the numerical simulations described in the associated publication (St-Laurent et al. 2020, Biogeosciences, https://doi.org/10.5194/bg-2020-117).

The dataset is in the standard, self-documented NetCDF format (extension .nc); see https://www.unidata.ucar.edu/software/netcdf/ for more information. Files in this format can be manipulated and displayed by a wide range of freely available software. The dataset includes a total of six (6) files that correspond to the six numerical experiments described in the Section "Methods" of the associated publication (St-Laurent et al.). Detailed information about the open source numerical model used in the study (Regional Ocean Modeling System, ROMS) is available at www.myroms.org. Additional information about the biogeochemical module is available in the "Supplementary" document of the associated publication (St-Laurent et al.).
