The landscape revealed by retreating glaciers provides evidence, much of it ephemeral, for subglacial processes that are difficult to observe directly. Glaciers that thin over rough bedrock surfaces continue to slide by regelation as adjacent subsurface cavity systems develop and enlarge. Subglacial deposits, including the cemented coatings we describe here, provide insight into subglacial conditions. Rock-coating, carbonate-cemented lithic...

We demonstrate that the glacier net inflow to the Arctic Ocean, specifically the net glacier volume loss, has been comparable to the combined river net inflow from the largest panarctic rivers. Open publication - Free publishing - More mass...
