Application of the Analytic Model Based on Energy Balance into the Lake Ice Simulation of Qinghai Lake

Gaoyuan qixiang, 2023
Lake ice is sensitive to climate change.Under the background of global warming， lake ice is generally declining， and even some lakes in the Northern Hemisphere may not freeze in the future.Lakes are widely distributed in the Qinghai-Xizang Plateau， but ...

Salinity impact on water flow and lake ice in Lake Vostok, Antarctica [PDF]

, 2003
Lake Vostok, isolated from direct exchange with the atmosphere for million years, provides a unique and so far inaccessible habitat. By using a numerical model, and recent lake geometry information, the lake circulation was investigated for different ...

Incorporation of particulates into accreted ice above subglacial Vostok lake, Antarctica [PDF]

, 2005
The nature of microscopic particulates in meteoric and accreted ice from the Vostok (Antarctica) ice core is assessed in conjunction with existing ice-core data to investigate the mechanism by which particulates are incorporated into refrozen lake water.

Subglacial Lake Ellsworth: a candidate for in situ exploration in West Antarctica [PDF]

, 2004
Radio-echo sounding reveals a 10 km-long lake beneath similar to3.4 km of ice near the Ellsworth Mountains in West Antarctica, 20 km from the ice divide. Subglacial Lake Ellsworth is located within a distinct topographic hollow, which is similar to1.5 km

Potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets [PDF]

, 2013
We use the Shreve hydraulic potential equation as a simplified approach to investigate potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets. We validate the method by demonstrating its ability

The "tipping" temperature within Subglacial Lake Ellsworth, West Antarctica and its implications for lake access. [PDF]

, 2011
We present results from new geophysical data allowing modelling of the water flow within Subglacial Lake Ellsworth (SLE), West Antarctica. Our simulations indicate that this lake has a novel temperature distribution due to significantly thinner ice than ...

Is Vostok lake in steady state? [PDF]

, 2004
Stable-isotope (D and 18O) data from the Vostok (East Antarctica) ice core are used to explore whether or not subglacial Vostok lake is in isotopic steady state. A simple box model shows that the lake is likely to be in steady state on time-scales of the

A stratigraphic link across 1100 km of the Antarctic Ice Sheet between the Vostok ice-core site and Titan Dome (near South Pole) [PDF]

, 2000
Isochronous internal ice-sheet layering, measured from airborne 60 MHz radar, was traced between Lake Vostok and the Titan Ice Dome (100 km from South Pole Station), Antarctica. Three layers were selected between Ridge B and Titan Dome, and between Ridge

Glacio-limnological interactions at lake-calving glaciers [PDF]

, 2012
Iceberg calving is an efficient ablation process which introduces mechanical instability to glacier systems and can cause non-linear climatic response.
