Waldrop-Bergman and Heuzé (2018) Influence of initial stratification, wind and sea ice on the modelled oceanic circulation in Nares Strait, northwest Greenland

L. Waldrop Bergman and C. Heuzé (2018) “Influence of initial stratification, wind and sea ice on the modelled oceanic circulation in Nares Strait, northwest Greenland“, Ocean Science Discussion, doi:10.5194/os-2018-122.

/!\ Discussion open until 19 Dec. Please comment on our work, especially if you know about the sea ice model.

As we were implementing a regional configuration of MITgcm between Greenland and Canada, we realised that there were too many choices to make and too few data to justify them. We thus performed a sensitivity experiment instead to determine which had the largest influence on our modelled ocean:

  • the initial temperature and salinity profiles,
  • the resolution of the wind forcing,
  • or the initial sea ice thickness?

We showed that hydrographic observations that capture the E-W or N-S density gradients were more crucial than a high resolution wind.
