    The hydrodynamic circulation model results are retrieved from an ocean model version of the Regional Ocean Modeling System (ROMS) (www.myroms.org, Haidvogel et al, 2008, Shchepetkin and McWilliams 2005, 2009) applying a horizontal resolution of 800m. This model covers the entire Norwegian coast and parts of the adjacent seas, and the technical details are described in Albretsen et al. (2011). At the surface the ocean model applied atmospheric fields from a high-resolution simulation with the WRF meso-scale wind model (www.wrf-model.org<http://www.wrf-model.org/>, Dudhia, 1993). The model statistics were retrieved from two separate simulations covering the period from January-August both in 2013 and 2014. Tidal forcing was retrieved from the global TPXO model of ocean tides (Egbert and Erofeeva, 2002) and added along the open boundary in addition to daily averaged surface elevation, currents and hydrography from the operational forecast from the Norwegian Meteorological Institute. No data assimilation or any kind of surface relaxation was used.

  • The Svalbard-800m model is run and disseminated by the Institute of Marine Research, Norway. S800 is a renewed version of the 800m-model system described in Hattermann et al. (2016) run for the years 2007-2010, while the B800-model is based on a one-year simulation (2010) using similar external forcings as the S800-model.
