Determining lake surface water temperatures worldwide using a tuned one-dimensional lake model (FLake, v1) [PDF]

, 2016
A tuning method for FLake, a one-dimensional (1-D) freshwater lake model, is applied for the individual tuning of 244 globally distributed large lakes using observed lake surface water temperatures (LSWTs) derived from along-track scanning radiometers ...

Scientific access into Mercer Subglacial Lake: scientific objectives, drilling operations and initial observations

Annals of Glaciology, 2021
The Subglacial Antarctic Lakes Scientific Access (SALSA) Project accessed Mercer Subglacial Lake using environmentally clean hot-water drilling to examine interactions among ice, water, sediment, rock, microbes and carbon reservoirs within the lake water

Interaction between ice sheet dynamics and subglacial lake circulation: a coupled modelling approach [PDF]

The Cryosphere, 2010
Subglacial lakes in Antarctica influence to a large extent the flow of the ice sheet. In this study we use an idealised lake geometry to study this impact. We employ a) an improved three-dimensional full-Stokes ice flow model with a nonlinear rheology, b)

The backscattering characteristics of thermokarst lake ice in the qinghai-tibet plateau from SAR [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
A thermokarst lake is an important indicator of changes in climate, which cause considerable thermal distribution to the surrounding permafrost. The imaging radar has demonstrated the capability to determine when and which lakes freeze or do not freeze ...

Shrinking sea ice, increasing snowfall and thinning lake ice: a complex Arctic linkage explained [PDF]

, 2016
The dramatic shrinkage of Arctic sea ice is one of the starkest symptoms of global warming, with potentially severe and far-reaching impacts on arctic marine and terrestrial ecology (Post et al 2013 Science 341 519–24) and northern hemisphere climate ...

Simulating lake ice phenology using a coupled atmosphere–lake model at Nam Co, a typical deep alpine lake on the Tibetan Plateau [PDF]

The Cryosphere
Simulating the ice phenology of deep alpine lakes is important and challenging in coupled atmosphere–lake models. In this study, the Weather Research and Forecasting (WRF) model, coupled with two lake models, the freshwater lake (WRF–FLake) model and the

Optical Properties of Deep Ice at the South Pole - Absorption [PDF]

, 1997
We discuss recent measurements of the wavelength-dependent absorption coefficients in deep South Pole ice. The method uses transit time distributions of pulses from a variable-frequency laser sent between emitters and receivers embedded in the ice.

Climatic control on the peak discharge of glacier outburst floods

, 2007
Lakes impounded by natural ice dams occur in many glacier regions. Their sudden emptying along subglacial paths can unleash similar to 1 km(3) of floodwater, but predicting the peak discharge of these subglacial outburst floods ('jokulhlaups') is ...

Source of Lake Vostok Cations Constrained with Strontium Isotopes [PDF]

, 2016
Lake Vostok is the largest sub-glacial lake in Antarctica. The primary source of our current knowledge regarding the geochemistry and biology of the lake comes from the analysis of refrozen lake water associated with ice core drilling. Several sources of

An Investigation of Ice Surface Albedo and Its Influence on the High-Altitude Lakes of the Tibetan Plateau

Remote Sensing, 2018
Most high-altitude lakes are more sensitive to global warming than the regional atmosphere. However, most existing climate models produce unrealistic surface temperatures on the Tibetan Plateau (TP) lakes, and few studies have focused on the influence of
