A simple parametrization of mélange buttressing for calving glaciers

Abstract. Both ice sheets in Greenland and Antarctica are discharging into the ocean. In many regions along coast of sheets, icebergs calve a bay. If addition through calving is faster than their transport out embayment, will be frozen mélange with surrounding sea winter. this case, buttressing effect can considerably stronger any by mere would be. This turn stabilizes glacier terminus leads to reduction rates. Here we propose simple parametrization which an upper bound on rates used numerical analytical modelling.
