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.

该奖项支持一个为期两年的项目，该项目旨在解决关于通过沃斯托克湖的质量和能量流动的基本问题，沃斯托克湖是南极洲东部的一个冰下湖泊，被密封在近4公里的冰下。该项目将包括开发湖泊环流模型，并辅以对湖泊及周边地区新的破冰雷达数据的分析。这个项目将有助于准确地确定湖中融化和冻结的区域，并有助于提供对湖泊形式的改进估计。综合数据分析和建模工作将为制定沃斯托克湖水域生物区系取样和从沃斯托克湖恢复沉积物用于古气候研究的国际计划提供关键框架。
