would this design solution block the flow of warm water into the bay stop enough energy transfer to prvent the melt occuring at this glacier or only some of it. 

 

 

ear topography of the sea bottom and some of the water layer above it between Disko Bay and the Jakobshavn Glacier is shown below. Disko Bay Ilulissat Icefjord summer fresh layer Jakobshavn Glacier ice bergs 1004 wal warmest water 550 m basin Fjord sill 250 m depth 50 km Sub-glacial discharge Proposed Solution: To prevent future melt, a 100-meter-high wall with sloping sides of 15° to 45 could be built across the 5-kilometer fjord sill shown in diagram above. This could be done by dredging around 0.1 cubic kilometers of gravel and sand from the ocean bottom further out (on Greenland's continental shelf) and adding it to the existing fjord sill to raise its height. This artificial embankment, or berm, would then be covered in concrete to stop it from being eroded. Feasibility: The scale of the berm would be comparable with other large civil-engineering projects, such as: • The Suez Canal excavated ten times more material - 1 cubic kilometer Hong Kong's airport required ornu to ku'll1 Sill spillway
