Mass and Energy Fluxes Through Lake Vostok: Observations and Models

该奖项支持一个为期两年的项目，该项目旨在解决有关通过东南极冰下湖泊沃斯托克湖的质量和能量流动的基本问题，该湖被封在近4公里的冰层之下。该项目将包括开发湖泊环流模型，并辅之以对湖泊及其周围地区新的冰层穿透雷达数据的分析。该项目将有助于准确地确定湖泊内的融化和结冰区域，并有助于提供对湖泊形态的更好估计。综合的数据分析和建模工作将为制定国际计划提供一个关键框架，以便对沃斯托克湖水中的生物群进行采样，并从沃斯托克湖中回收沉积物进行古气候研究。

0088047BellThis award supports a two year project to address fundamental questions about the mass and energy flux through Lake Vostok, a subglacial lake in East Antarctica, sealed beneath almost 4 kilometers of ice. The project will involve developing lake circulation models, complemented by the analysis of new ice penetrating radar data over the lake and surrounding regions. This project will help to accurately define the regions of melting and freezing within the lake and help to provide an improved estimate of the form of the lake. The combined data analysis and modeling effort will provide a critical framework for developing international plans to sample the waters of Lake Vostok for biota and to recover sediments from Lake Vostok for paleoclimate studies.
