Title: High-resolution NEMO4 model of Cumberland Bay, South Georgia, 2001 to 2010

Abstract: This data-set consist of the required model set up files to reproduce a NEMO4 high-resolution model of Cumberland Bay, South Georgia, for the years 2001 to 2010 as described in the thesis 'Oceanographic Variability in Cumberland Bay, South Georgia: Implications for Glacier Retreat and Fisheries Management' Joanna Zanker. Files required to reproduce the process tests detailed in the thesis are also provded with the relevant names.

Keywords: South Georgia, Cumberland Bay, NEMO 

Personnel: Creatpr amd lead contact: Joanna Zanker, ORCHID: 0009-0006-6500-4514, joazan@bas.ac.uk, British Antarctic Survey
Project supervisor: Emma Young, eyoung@bas.ac.uk, British Antarctic Survey

Methodology: The model was developed in NEMO version 4.0.6, a new configuratiom should be compiled with the .nc files provided. Additional data is required from the ERA5 atmospheric reanalysis data-set (Hersbach et al. 2020) and the South Georgia regional model (Young et al. 2016). The freshwater forcing files (ln_rnf) are labeled 'MODSUB_9010_y*' and are calculated via an offline plume model as detailed in the thesis for which the data is supporting. The model output is managed by xios-2.5.  

Temporal coverage: The model is able to simulate the years 2000 to 2012, with the year 1999 used as spin-up. The year 2001 to 2010 are analysed in the thesis. 

Spatial coverage: The model domain is -36.86 to -35.926 longitude and -54.45 to -53.97 latitude.

Resolution: The model horizontal resolution is 1/500 degrees in latitude and 1/300 degrees in longitude. In the vertical the levels are gradually stretched such that the layer thickness increases gradually from ~1 m at the surface to ~30 m apart at depth.

Location: Cumberland Bay, South Georgia.
