Rapid atmospheric warming since the mid-twentieth century has increased temperature-
dependent erosion and sediment-transport processes in cold environments, affecting food …

Abstract Groundwater 18O/16O, 2H/1H, 13C/12C, 3H, and 14C data can help quantify
molecular movements and chemical reactions governing groundwater recharge, quality …

Terrestrial hydrology is central to the Arctic system and its freshwater circulation. Water
transport and water constituents vary, however, across a very diverse geography. In this …

Surface mass balance (SMB) provides mass input to the surface of the Antarctic and
Greenland Ice Sheets and therefore comprises an important control on ice sheet mass …

Melting is pervasive along the ice surrounding Antarctica. On the surface of the grounded ice
sheet and floating ice shelves, extensive networks of lakes, streams and rivers both store …

Remote sensing of river discharge (RSQ) is a burgeoning field rife with innovation. This
innovation has resulted in a highly non-cohesive subfield of hydrology advancing at a rapid …

Abstract The Miocene epoch, spanning 23.03–5.33 Ma, was a dynamic climate of sustained,
polar amplified warmth. Miocene atmospheric CO2 concentrations are typically …

Approximately half of Greenland's current annual mass loss is attributed to runoff from
surface melt. At higher elevations, however, melt does not necessarily equal runoff, because …

River piracy—the diversion of the headwaters of one stream into another one—can
dramatically change the routing of water and sediment, with a profound effect on landscape …

The geological record of landforms and sediments produced beneath deglaciating ice
sheets offers insights into inaccessible glacial processes. Large subglacial valleys formed …
