Abstract

This dataset includes model input, code, and output used in the manuscript submitted to Journal of Advances in Modeling Earth Systems (Yin et al., 2024). In this work, the authors used a numerical model to understand how the seabed can affect bottom water acidification over the Northern Gulf of Mexico hypoxic zone. The model was built on the previously developed coupled hydrodynamic-sediment transport-biogeochemistry model (Moriarty et al., 2017) and expanded to include DIC and TAlk for ocean acidification. As described in manuscript of Yin et al. (2024), the model can reproduce the seabed-water column exchange of biologically important solutes including DIC and TAlk. This model can be used for quantifying the role of benthic fluxes in driving bottom water acidification over continental shelves.

Description

These files are compressed versions of input files, model code, and output used for the associated manuscript (Yin et al., 2024). Many of the input and output files use the NetCDF (Network Common Data Form) file format. These have "nc" as a file extension and can be read using a variety of open-source tools: see http://www.unidata.ucar.edu/software/netcdf/docs/.
