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.","url":"http:\/\/bolin.su.se\/data\/wiskandt-2024-sof-sill-1","keywords":["Marine","Circulation","Ice-ocean modelling","Hydraulic control","High resolution regional ocean modelling","Greenland fjord circulation","Earth science services > Models > Ocean general circulation models (ogcm)\/regional ocean models"],"creator":{"@type":"Person","name":"Jonathan Wiskandt"},"citation":"Jakobsson, M., Mayer, L.
