Record #175088:

Dynamics of Ronne Ice Shelf and its interaction with the ocean / Adrian Jenkins.

Title: Dynamics of Ronne Ice Shelf and its interaction with the ocean / Adrian Jenkins.
Author(s): Jenkins, Adrian.
Date: 1992.
Publisher: Cambridge :
Abstract: Presents results of detailed glaciological studies in 1985-88 at 28 sites on approximate flowline extending 760 km across Ronne Ice Shelf, from grounding line of Rutford Ice Stream to ice front. Parameters measured included velocity, thickness and deformation rate of ice shelf, and elevation, temperature and accumulation rate at its upper surface. Calculations indicate that within 300 km of grounding line and 100 km of calving front, ice melts into underlying ocean, whilst over most of intervening 360 km marine ice accumulates on ice shelf base. Melting is most intense near inland and seaward extremities of flowline. Results of mass balance studies indicate that 85% of ice discharged from inland ice sheet via Rutford Ice Stream melts into ocean before reaching calving front. Simple numerical model of meltwater driven buoyant convection indicates that mass balance at base of ice shelf is sensitive to depth of grounding line, basal slope and ocean temperature. Discusses implications of results for mass budget and stability of West Antarctic Ice Sheet and global ocean circulation, with particular reference to role played by ice shelf water in formation of Antarctic bottom water.
