Editorial statement
This paper is worthy of a highlight. The authors show the importance of a process that has been known to exist but hasn’t been measured in this detail before. From a public interest perspective, the results might be tricky to explain in general terms, but the key results fit within the category of “major discovery” and/or “mystery”.

Short summary
We develop a method using ICESat-2 data to measure how Antarctic grounding lines (GLs) migrate across the tide cycle. At an ice plain on the Ronne Ice Shelf we observe 15 km of tidal GL migration, the largest reported distance in Antarctica, dominating any signal of long-term migration. We identify four distinct migration modes, which provide both observational support for models of tidal ice flexure and GL migration and insights into ice shelf–ocean–subglacial interactions in grounding zones.
