"We went from this feature not being there, to suddenly, bam, this big mound had risen from the sea-bed. This was a really big surprise."
- Tavi Murray, glaciologist/study co-author

While many relic drumlins are well known features in once ice-covered areas, this is the first time an active one has been observed.
