Dynamic Deglacial Evolution of Interior Seaways and Ice Streams in the Weddell Sea Embayment
Abstract Improving our understanding of Antarctic glacial dynamics is essential for accurately predicting ice sheet behavior and its contribution to global sea level rise under future climate scenarios. The Weddell Sea Embayment, which channels ice from East Antarctica, West Antarctica, and the Antarctic Peninsula into the Filchner‐Ronne Ice Shelf, is ...

We present a 25‐stage reconstruction of the ice‐flow pattern evolution of the Scandinavian Ice Sheet based on mapping and analysis of ~240 000 subglacial lineations and lineation fields across Norway, Sweden, Finland, and parts of NW Russia. Our reconstruction uses a glacial geomorphological inversion approach, in which we generated 611 individual ...

Rheologisch-Glaziologische Untersuchungen om Firngebeit des Grönländischen Inlandeises.
The results of the rheological-glaciological investigations, which were conducted mainly at the Jarl-Joset Station at the time of the International Glaciological Greenland Expedition in 1957- 60, are dealt with in two sections. In the first section, four

Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

An integrated Structure-from-Motion and time-lapse technique for quantifying ice-margin dynamics
Fine resolution topographic data derived from methods such as Structure from Motion (SfM) and Multi-View Stereo (MVS) have the potential to provide detailed observations of geomorphological change, but have thus far been limited by the logistical ...

Probing the firn refractive index profile using antenna response
The Radio Neutrino Observatory-Greenland (RNO-G, at Summit Station) experiment comprises an extensive fat-dipole antenna array deployed into ice boreholes over an eventual area of approximately 35 km2.

Lidar-based snow monitoring from aerial lifts: Gondola deployment in the Austrian Alps
Monitoring snow distribution in alpine terrain is critical for hydrology, avalanche safety, and climate research, yet traditional surveys are costly, hazardous, and spatially sparse.

Reconnaissance Study of glacier energy balance in North Greenland, 1993–94
Reconnaissance energy-balance studies were made for the first time at two sites in North Greenland to compare with conditions in West Greenland. The field experiments were planned to save weight because it is expensive to operate in North Greenland.

Polarimetric multi-offset radio-echo sounding with a radio frequency-over-fiber ApRES system
Polarimetric multi-offset radio-echo sounding offers improved constraints on englacial thermal conditions, basal properties and ice crystal orientation compared to standard monostatic observations.

Development of the British Antarctic Survey Rapid Access Isotope Drill
The British Antarctic Survey Rapid Access Isotope Drill is an innovative new class of electromechanical ice drill, which has recently been used to drill the deepest dry hole drilled by an electromechanical auger drill. The record-breaking depth of 461.58
