Firstly, the meltwater flows from the grounded ice sheet into the ocean, just beneath the floating ice shelf. According to the researchers working on the project, this subglacial meltwater then has a knock-on impact, initiating ocean circulation beneath the ice shelves, which then creates “plumes” of water. These plumes then entrain warmer ocean water, triggering a higher rate of melting that carves out the afore-mentioned channels.
