基本信息

项目摘要

ABSTRACT OPP-9702025 ANDREAS, EDGAR COLD REGIONS RESEARCH AND ENVIRONMENTAL LABORATORY This research project is a key component of a large, coordinated, multi-investigator program, Surface Heat Budget of the Arctic (SHEBA) Ocean. The research program will be conducted for 14 months from a ship frozen into the ice pack. These investigators will measure atmospheric conditions near the surface of the permanent ice cap of the Arctic Ocean to determine the flux of heat radiating onto and off of the ice floe. They will determine how atmospheric heating is coupled to adsorption of heat by the ice. These measurements are critical to understanding how heat is reflected or absorbed by the ice as it melts in the summer and thickens in the winter in response to seasonal variations in climate. The heat flux measurement program makes an essential contribution to the SHEBA team of researchers who will measure atmospheric vapiables with a large array of instruments on the ice floe and aircraft flying above as well as ice and ocean property measurements made on and below the ice floe. The combined set of measurements in SHEBA will allow refinement of climate models for the Arctic region. Those improved models will lead to better predictions of the climate and the permanence of the Arctic ice cap under a proposed global warming that could occur if atmospheric carbon dioxide levels are increased above present levels.
摘要 粤ICP备0902025号 埃德加·安德烈斯 寒区研究 和环境实验室 该研究项目是一个大型的,协调的,多研究者计划的关键组成部分,北极(SHEBA)海洋的表面热收支。 这项研究计划将在一艘被冻成冰块的船上进行14个月。这些研究人员将测量北冰洋永久冰盖表面附近的大气条件,以确定辐射到浮冰上和浮冰上的热量通量。他们将确定大气加热如何与冰的热量吸收相结合。这些测量对于了解热量是如何被冰反射或吸收的至关重要,因为它在夏季融化,在冬季变厚,以应对气候的季节性变化。热通量测量计划为SHEBA研究人员团队做出了重要贡献,他们将在浮冰上使用大量仪器测量大气vapiables,以及在浮冰上和浮冰下飞行的飞机以及冰和海洋属性测量。SHEBA的综合测量将使北极地区的气候模型更加精确。这些改进的模型将有助于更好地预测气候以及在如果大气中二氧化碳含量超过目前水平而可能出现的拟议全球变暖情况下北极冰盖的永久性。
