Understanding drivers of glacier-length variability over the last millennium [PDF]

The Cryosphere, 2021
Changes in glacier length reflect the integrated response to local fluctuations in temperature and precipitation resulting from both external forcing (e.g., volcanic eruptions or anthropogenic CO2) and internal climate variability.

The Red Rock ice cliff revisited – six decades of frontal, mass and area changes in the Nunatarssuaq area, Northwest Greenland

Journal of Glaciology, 2020
We present changes of the ice margin in Northwest Greenland at the Eastern part of the Nunatarssuaq Ice Cap (NIC) over six decades. The ice margin in this area terminates as a near-vertical ice cliff of between 9 and 33 m thickness. During the years 1954–

Climate change and its relation to the fluctuation in glacier mass balance in the Cordillera Blanca, Peru: A review

Acta Universitatis Carolinae Geographica, 2018
This review article describes the main probable causes of glacier fluctuations in the Cordillera Blanca since the end of the Little Ice Age. The Cordillera Blanca glaciers reached their last maximum extent during the Little Ice Age and have been ...

Holocene history of the Ullukam Glacier

Лëд и снег, 2015
Using instrumental archives, aerial photographs, satellite images, old maps, descriptions of early explorers and old photographs we identified and mapped nine front positions of the Ullukam Glacier (SW slope of Elbrus) for the period from the end of XIX ...

Glacier change in Norway since the 1960s – an overview of mass balance, area, length and surface elevation changes

Journal of Glaciology, 2020
In this paper, we give an overview of changes in area, length, surface elevation and mass balance of glaciers in mainland Norway since the 1960s. Frontal advances have been recorded in all regions except the northernmost glaciers in Troms and Finnmark ...

Using the Photostationary State of Arylazopyrazoles to Control Phase Transitions of Liquid Crystals

Advanced Functional Materials, EarlyView.
A series of new arylazopyrazole photoswitches is designed as dopants for liquid crystalline materials. Unprecedented, the distribution of photoisomers at the photostationary state upon irradiation with light of specific wavelengths (365, 460, 520 nm) is used to control the liquid crystalline phase transitions under isothermal conditions, including ...

Mass balance of Trambau Glacier, Rolwaling region, Nepal Himalaya: in-situ observations, long-term reconstruction and mass-balance sensitivity

Journal of Glaciology, 2019
We conducted a mass-balance study of debris-free Trambau Glacier in the Rolwaling region, Nepal Himalaya, which is accessible to 6000 m a.s.l., to better understand mass-balance processes and the effect of precipitation on these processes on high ...

SI‐bioATRP in Mesoporous Silica for Size‐Exclusion Driven Local Polymer Placement

Advanced Functional Materials, EarlyView.
An enzyme‐catalyzed surface‐initiated atom transfer radical polymerization (SI‐bioATRP) of an anionic monomer within mesoporous silica particles, using hemoglobin as a catalyst, allows for controlling the location of the formed polymer via size‐exclusion effects between the nanopores and the biomacromolecules, thereby opening routes to functional ...

Glacier inventory and recent glacier variations in the Andes of Chile, South America

Annals of Glaciology, 2017
The first satellite-derived inventory of glaciers and rock glaciers in Chile, created from Landsat TM/ETM+ images spanning between 2000 and 2003 using a semi-automated procedure, is presented in a single standardized format.

Differences in the transient responses of individual glaciers: a case study of the Cascade Mountains of Washington State, USA

Journal of Glaciology, 2022
Mountain glaciers have response times that govern retreat due to anthropogenic climate change. We use geometric attributes to estimate individual response times for 383 glaciers in the Cascade mountain range of Washington State, USA. Approximately 90% of
