Short summary
Arctic glaciers and ice shelves are retreating due to warmer oceans, but the link between ocean warming and ice loss is complex. We used a numerical model to study these processes in Milne Fiord, a unique site with an ice shelf and a tidewater glacier. Our results show that submarine melting is an important thinning mechanism and that glacier retreat will continue for decades. This research highlights the ongoing and future changes in Arctic ice structures.
