Early Mars volcanic sulfur storage in the cryosphere and formation of transient SO2-rich atmospheres during the Hesperian

open access: yes, 2016
In a previous paper (Chassefi\`ere et al., Icarus 223, 878-891, 2013), we have shown that most volcanic sulfur released to early Mars atmosphere could have been trapped in the cryosphere under the form of CO2-SO2 clathrates. Huge amounts of sulfur, up to

GIS- and field data based modeling of snow water equivalent in shrub tundra

open access: yesЛëд и снег, 2015
An approach for snow water equivalent (SWE) modelling in tundra environments has been developed for the test area on the Yamal peninsula. Detailed mapping of snow cover is very important for tundra areas under continuous permafrost conditions, because ...

Benthic Biodiversity, Carbon Storage and the Potential for Increasing Negative Feedbacks on Climate Change in Shallow Waters of the Antarctic Peninsula

open access: yesBiology, 2022
The importance of cold-water blue carbon as biological carbon pumps that sequester carbon into ocean sediments is now being realised. Most polar blue carbon research to date has focussed on deep water, yet the highest productivity is in the shallows ...

KINETICS OF GAS HYDRATES FORMATION AND GROWTH BASED ON MODIFIED ICE

open access: yesИзвестия высших учебных заведений: Нефть и газ, 2017
The results of the studies of influence of polyvinylpyrrolidone on the kinetics of formation and the growth of Freon-12 gas hydrate are presented. Based on the P-V-T measurements the degree of conversion of ice into gas hydrate at various concentrations ...

Consequences of the 2019 Greenland Ice Sheet Melt Episode on Albedo

open access: yesRemote Sensing, 2021
In mid-June 2019, the Greenland ice sheet (GrIS) experienced an extreme early-season melt event. This, coupled with an earlier-than-average melt onset and low prior winter snowfall over western Greenland, led to a rapid decrease in surface albedo and ...

Catastrophic ice lake collapse in Aram Chaos, Mars

open access: yes, 2014
Hesperian chaotic terrains have been recognized as the source of outflow channels formed by catastrophic outflows. Four main scenarios have been proposed for the formation of chaotic terrains that involve different amounts of water and single or multiple

Suitability of ground-based SfM-MVS for monitoring glacial and periglacial processes [PDF]

open access: yes, 2016
Photo-based surface reconstruction is rapidly emerging as an alternative survey technique to lidar (light detection and ranging) in many fields of geoscience fostered by the recent development of computer vision algorithms such as structure from motion ...

The Global Social and Economic Consequences of Mountain Cryospheric Change

open access: yesFrontiers in Environmental Science, 2019
The mountain cryosphere provides fresh water and other ecosystem services to half of humanity. The loss of the mountain cryosphere due to global warming is already evident in many parts of the world and has direct implications to people living in ...

Accuracy of UAV Photogrammetry in Glacial and Periglacial Alpine Terrain: A Comparison With Airborne and Terrestrial Datasets

open access: yesFrontiers in Remote Sensing, 2022
Unoccupied Aerial Vehicles (UAVs) equipped with optical instruments are increasingly deployed in high mountain environments to investigate and monitor glacial and periglacial processes.

A Holistic Assessment of 1979–2016 Global Cryospheric Extent

open access: yesEarth's Future, 2021
The cryosphere plays a major role in earth's climate system. Most cryospheric assessments focus on one or more of its components and their response to climate change.
