Mass and Energy Fluxes Through Lake Vostok: Observations and Models

0088047贝尔该奖项支持一个为期两年的项目，以解决有关通过东方湖，南极洲东部的一个冰下湖泊，密封在近4公里的冰下的质量和能量通量的基本问题。 该项目将涉及开发湖泊环流模型，并辅之以分析湖泊和周边地区的新的冰层穿透雷达数据。 该项目将有助于准确界定湖泊内的融化和冻结区域，并有助于提供对湖泊形态的更好估计。 综合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，以便对沃斯托克湖的沃茨进行生物群取样，并从沃斯托克湖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.
