Younger Dryas glacier advances in the tropical Andes driven by increased precipitation [PDF]

Scientific Reports
There is currently a debate about the timing and drivers of former glacier behaviour and climate change in the tropical Andes. Using 10Be dating we determined the ages of 21 boulders on moraines in the Santa Cruz Valley, Peru (∼10°S, altitudes ~ 4100 to ~

Snowfall decrease in recent years undermines glacier health and meltwater resources in the Northwestern Pamirs [PDF]

Communications Earth & Environment
Central Asia hosts some of the world’s last relatively healthy mountain glaciers and is heavily dependent on snow and ice melt for downstream water supply, though the causes of this stable glacier state are not known.

Prehospital locoregional anesthesia: a case series [PDF]

Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine
Background Standard prehospital pain management relies on opioids, which involved avoidable risks. Few studies have evaluated pre-hospital locoregional anesthesia (LRA), especially fascia iliaca compartment blocks (FICB) and femoral nerve blocks (FB). We

Genomic Data Suggests Pathways of Modern White Poplar (Populus alba L.) Range Formation in the Postglacial Era [PDF]

Plants
The white poplar (Populus alba L.) is an economically significant tree species with a natural distribution spanning an extensive region of Eurasia. Nevertheless, there is currently no hypothesis regarding the historical shaping of this range.

Sub-seasonal variability of supraglacial ice cliff melt rates and associated processes from time-lapse photogrammetry [PDF]

The Cryosphere, 2022
Melt from supraglacial ice cliffs is an important contributor to the mass loss of debris-covered glaciers. However, ice cliff contribution is difficult to quantify as they are highly dynamic features, and the paucity of observations of melt rates and ...

An inventory of Norway's glaciers and ice-marginal lakes from 2018–19 Sentinel-2 data

Journal of Glaciology, 2022
We used Sentinel-2 satellite imagery at 10 m resolution to map the extent of Norway's glaciers and ice-marginal lakes over 2018–19. We applied a standardized semi-automated band ratio method to derive glacier outlines and ice-marginal lakes.

Reanalysis of long-term series of glaciological and geodetic mass balance for 10 Norwegian glaciers [PDF]

The Cryosphere, 2016
Glaciological and geodetic methods provide independent observations of glacier mass balance. The glaciological method measures the surface mass balance, on a seasonal or annual basis, whereas the geodetic method measures surface, internal, and basal mass

Controls on Ice Cliff Distribution and Characteristics on Debris‐Covered Glaciers

Geophysical Research Letters, 2023
Ice cliff distribution plays a major role in determining the melt of debris‐covered glaciers but its controls are largely unknown. We assembled a data set of 37,537 ice cliffs and determined their characteristics across 86 debris‐covered glaciers within ...

Spatio-temporal variability in geometry and geodetic mass balance of Jostedalsbreen ice cap, Norway

Annals of Glaciology, 2023
The Jostedalsbreen ice cap is mainland Europe's largest ice cap and accommodates 20% (458 km2 in 2019) of the total glacier area of mainland Norway.
