[{"name":"wiskandt-2024-sof-sill-1","title":"Setup files for MITgcm simulations (2D) of the Sherard Osborn Fjord with varying sill depth and subglacial discharge","summary":"This repository provides files to setup the MIT General Circulation Model (MITgcm, Mid 2020 Version) and run a set of experiments. \r\n\r\nThe experiments run can be used to analyze the circulation underneath the ice tongue of Ryder Glacier in Sherard Osborn Fjord. Furthermore a set of sensitivity experiments are available to investigate the response of the system and the melt rate to changes in the fjord sea floor geometry (namely the height of a sill in front of the ice shelf) and changes in subglacial discharge volume.\r\n\r\nThe simulations are in 2D (along-fjord and vertical) and span the cavity under the ice tongue and the first sill of located in the Sherard Osborn Fjord. The geometry is highly idealized and the simulations are initiated with averaged temperature and salinity profiles taken on the Ryder 2019 expedition with the Swedish icebreaker Oden.","citations":"Jakobsson, M., Mayer, L.
