I have a question regarding a proposed method of glacial #geoengineering: drilling a bunch of holes into #glaciers in #Antarctica and then pumping up the water that sits underneath them to allow the glacier to fall back down on the solid rock beneath to prevent further melting of it's underside and to slow down their speed. The water is then spread at the surface where it refreezes.
My question is: the water is seawater, so contains salt. What happens to that salt during the refreezing? Do we then have a bunch of salty brine sitting around on the surface? What consequences could that have?
(This method was mentioned in Kim Stanley Robinson's book The ministry for the Future, and was also mentioned in passing in the recent glacial geoengineering white paper mentioned here: https://www.science.org/content/article/avoid-sea-level-rise-some-researchers-want-build-barriers-around-world-s-most )
