ABSTRACT OPP-9872626 EICKEN, HAJO UNIVERSITY OF ALASKA The project will quantify the lateral and vertical meltwater movement and associated freshwater and heat fluxes in summer sea ice through the use of novel hydrological tracers. The fate of sea ice in the Arctic Ocean is a very important issue due to its effects on global and regional climate and economics. The investigator will use stable isotopes and fluorescent dyes to make a significant advance in the understanding of the driving forces responsible for melting sea ice. As such, the research will enable improvements in sea ice models that will allow better prediction of melting in response to global warming. The project will be conducted at the Surface Heat Budget of the Arctic (SHEBA) Ocean site in the Beaufort Sea where other studies underway will enhance the results of this project by providing validation of the techniques employed.

该项目将通过使用新的水文示踪剂来量化夏季海冰中横向和垂直融化水的移动以及相关的淡水和热通量。北冰洋海冰的命运是一个非常重要的问题，因为它对全球和区域气候和经济产生影响。研究人员将使用稳定的同位素和荧光染料，在理解导致海冰融化的驱动力方面取得重大进展。因此，这项研究将使海冰模型得到改进，从而能够更好地预测融化以应对全球变暖。该项目将在波弗特海的北冰洋(SHEBA)海洋表面热量预算地点进行，在那里正在进行的其他研究将通过验证所采用的技术来加强这一项目的成果。
