High tide floating ice shelves
WebApr 10, 1995 · Antarctica's ice shelves stabilize the ice sheet and, therefore, understanding processes affecting the mass budgets of ice shelves is important for estimating … WebWhen bedrock near the grounding line acts as a fulcrum, leverage from the ice shelf dropping at low tide can cause significant (~ 1 cm) uplift in the first few kilometers of grounded ice. This uplift and the corresponding depression at high tide lead to basal pressure variations of sufficient magnitude to influence subglacial hydrology.
High tide floating ice shelves

WebIce shelves are formed where flow rate is high and glaciers spill into somewhat protected waters, forming a long-lasting covering over the water below that can be several hundred meters thick. The Ross Ice Shelf is the largest of these in Antarctica. Unlike seasonal sea ice, ice shelves persist year-round and are significantly thicker, as seen ... Web1992). To accurately monitor long-term trends in ice shelf surface height, the tide component must be removed from the height measurement, such that all ice shelf heights are referred to a “tide-free” datum. The vertical displacement of an ice shelf can be measured to high accuracy using global positioning
