Abstract

The dataset includes model outputs used in the associated publication (Friedrichs et al.), which used the United States Eastern Continental Shelf (USECoS) biogeochemical model embedded in the Regional-Ocean-Modeling-System (ROMS) to examine the impact of the oceanic circulation on the nitrogen budget of the Mid-Atlantic Bight (MAB). The model simulation covers the period 2004 to 2008 and is fully described in the associated publication. The model simulation highlights that the horizontal along-shelf and across-shelf fluxes dominate the spatiotemporal variability of net community production (NCP) in the MAB. The highest NCP is found in a year when inorganic nitrogen entering from across the continental slope is high and terrestrial inputs are low.

Description

This dataset features the results from the numerical simulation described in the associated publication (Friedrichs et al.). The simulation results are 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 results from the simulation are divided into monthly files (suffix _0001 to _0061) 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). Detailed information about the open source numerical model used in the study (Regional Ocean Modeling System, ROMS) is available at www.myroms.org

File Name

Description

ocean_avg_00xx.nc

Time-averaged oceanic fields (Jan. 2004 to Dec. 2008). Each file contains 30 days worth of results and the fields have a temporal resolution of 1 day.

ocean_dia_00xx.nc

Time-averaged oceanic diagnostic fields (Jan. 2004 to Dec. 2008). Each file contains 30 days worth of results and the diagnostics have a temporal resolution of 3 days. Diagnostics *_hadv, *_vadv, *_rate, *_vdiff, P_Production, NO3_uptake and C_excess_uptake are vertically-integrated over the cell’s thickness (units per square meter).
