The aims of this review are to:(a) describe and interpret structures in valley glaciers in
relation to strain history; and (b) to explore how these structures inform our understanding of …

Coupling between runoff, hydrology, basal motion, and mass loss (“hydrology-dynamics”) is
a critical component of the Greenland Ice Sheet system. Despite considerable research …

Ice sheets are currently ignored in global methane budgets,. Although ice sheets have been
proposed to contain large reserves of methane that may contribute to a rise in atmospheric …

Atmospheric warming is increasing surface melting across the Antarctic Peninsula, with
unknown impacts upon glacier dynamics at the ice-bed interface. Using high-resolution …

Supraglacial lakes are important to ice sheet mass balance because their development and
drainage has been linked to changes in ice flow velocity and ice shelf disintegration …

Albedo—a primary control on surface melt—varies considerably across the Greenland Ice
Sheet yet the specific surface types that comprise its dark zone remain unquantified. Here …

Remote sensing is commonly used to monitor supraglacial lakes on the Greenland Ice
Sheet (GrIS); however, most satellite records must trade off higher spatial resolution for …

Supraglacial lakes (SGLs) are now known to be widespread in Antarctica, where they
represent an important component of ice sheet mass balance. This paper reviews how …

Supraglacial lake drainage events influence Greenland Ice Sheet dynamics on hourly to
interannual timescales. However, direct observations are rare, and, to date, no in situ studies …

Supraglacial liquid water at the margins of ice sheets has an important impact on the surface
energy balance and can also influence the ice flow when supraglacial lakes drain to the …
