Regional Ocean Modeling System (ROMS) output for an idealized East Greenland fjord sensitivity study: physical and biogeochemical fields
We use a 3-dimensional, terrain-following, hydrostatic Regional Ocean Modeling System (ROMS) (Haidvogel et al., 2008) to simulate processes within an idealized fjord with features (dimensions, water mass properties, and subglacial discharge rates) similar to those observed for many south east Greenl...
