Could underwater walls keeping warm water away from glaciers be the key to limiting future ice melt? Not so fast, new research says.
Underwater Glacier-Guarding Walls Could Have Unintended Consequences - Eos
Although they would likely impede the warm currents that melt glaciers, such walls would also likely block fish migration and nutrient upwelling, harming marine ecosystems and Greenland fisheries.

An Antarctic Ecosystem Influenced by Coastal Currents
It took us about a week to get there, and years of preparation to be ready for the journey that awaited us once we arrived. Alas, after a few plane rides, a few days loading the boat with all our gear, and 5 days sailing across the infamously rough Drake Passage, Palmer Station came into sight from the bow of the R.V.
