This dataset includes model input, code, and output used in the publication Birchler et al. (2018, Journal of Marine Science and Engineering), which used a coupled hydrodynamic-sediment transport-biogeochemical model to investigate the roles of resuspension, deposition, on biodiffusion on the behavior of short-lived radioisotopes in an idealized one-dimensional model setting. Model development for this project focused on incorporating radioisotope tracers into the sediment transport module in the Regional Ocean Modeling System (ROMS). As described in Birchler et al. (2018, Journal of Marine Science and Engineering), the model can account for supply and sorption of radioisotope tracers in the water column; biodiffusion of radioisotope tracers within the seabed; storage of radioisotope activity and inventory in the seabed; radioisotope decay in the seabed; and resuspension and removal of radioisotope tracers.
These files are compressed versions of input files, model code, and output used for an associated publication in Journal of Marine Science and Engineering (Birchler et al., 2018). Compressed files with the .gz file extension can be opened with Gzip GNU software (open source). Compressed files with the .tar file extension can be opened with Gzip Tar software (open source). 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/. For information about the Regional Ocean Modeling System (ROMS), its model code and input / output, see www.myroms.org.
