Abstract

The impacts of atmospheric nitrogen deposition on the chlorophyll and nitrogen dynamics of surface waters in the western North Atlantic (25-45N, 65-80W) were examined with a biogeochemical ocean model forced with a regional atmospheric chemistry model. The model simulations cover the period 2004 to 2008 and are fully described in the following reference: St-Laurent, P., et al., Impacts of atmospheric nitrogen deposition on surface waters of the western North Atlantic mitigated by multiple feedbacks, J. Geophys. Res. Oceans, vol.122, doi:10.1002/2017jc013072.

Description

This dataset features the results from 3 numerical simulations described in the following reference: St-Laurent, P., et al., Impacts of atmospheric nitrogen deposition on surface waters of the western North Atlantic mitigated by multiple feedbacks, J. Geophys. Res. Oceans, vol.122, doi:10.1002/2017jc013072. The simulation results are in the standard, self-documented NetCDF format (extension .nc); see https://www.unidata.ucar.edu/software/netcdf/ for more information. The 3 numerical simulations described in the reference document are archived in separate directories: run01, run02 and run03. The results from each simulation are further divided into monthly files (suffix _0001 to _0063) of two types. The first type holds time-averaged model fields (e.g., ocean_avg_0001.nc) and the second type holds time-averaged diagnostics (e.g., ocean_dia_0001.nc). In addition to the simulation results, the dataset includes the atmospheric deposition forcing that was prescribed at the ocean surface in the simulations. This atmospheric deposition forcing is in the same format as above (NetCDF) and it is archived in the directory “deposition_forcing”. The area covered by the study is 25-45deg.N and 65-80deg.W.
