ABSTRACT OPP-9701592 OPP-9701990 STEELE, MICHAEL HOLT, BENJAMIN UNIVERSITY OF WASHINGTON JET PROPULSION LABORATORY OPP-9702040 HOPKINS, MARK COLD REGIONS RESEARCH AND ENVIRONMENTAL LABORATORIES 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 utilize measurements of the thermal and dynamic conditions of the permanent ice cap of the Arctic Ocean to be incorporated into a modeling project that will determine the factors responsible for the summer melting of the sea ice. Their results will help determine how atmospheric and oceanic heating is coupled to adsorption of heat by the ice. These measurements are critical to understanding how heat is reflected or absorbed by the sea ice as it melts in the summer and thickens in the winter in response to seasonal variations in climate. The modeling program makes an essential contribution to the SHEBA team of researchers who will measure atmospheric and oceanic variables 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 and sea ice models 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.

STEELE, MICHAEL HOLT， BENJAMIN UNIVERSITY OF WASHINGTON喷气推进实验室HOPKINS， MARK COLD REGIONS RESEARCH AND ENVIRONMENTAL LABORATORY该研究项目是一个大型、协调、多研究者项目“北极（SHEBA）海洋表面热收支”的关键组成部分。该研究项目将在一艘被冰封的船上进行14个月。这些研究人员将利用对北冰洋永久冰帽的热和动力条件的测量，将其纳入一个建模项目，该项目将确定导致夏季海冰融化的因素。他们的研究结果将有助于确定大气和海洋的加热是如何与冰对热量的吸附相结合的。这些测量对于了解海冰在夏季融化和冬季变厚时如何反射或吸收热量是至关重要的，这是对气候季节性变化的反应。建模程序对SHEBA研究小组做出了重要贡献，他们将利用浮冰上的大量仪器和飞行在浮冰上方的飞机测量大气和海洋变量，以及浮冰上和浮冰下的冰和海洋特性测量。SHEBA的测量数据和海冰模型的组合将使北极地区的气候模型得到改进。这些改进的模型将有助于更好地预测气候和北极冰盖的持久性，因为如果大气中的二氧化碳含量高于目前的水平，就可能发生全球变暖。
