The research project will establish a Long-Term Observatory at the North Pole by installing an oceanographic mooring, launching a drifting buoy, and conducting repeated oceanographic transects for temperature and salinity. Oceanographic observations at the sites will be used to examine the long-term variability of the ocean and atmosphere in an area that has been undergoing rapid changes during the past decade. The current warming trend may presage a melting of the Arctic Ocean sea ice cover that has been predicted from Global Circulation Models as a response to global warming. Determination of the variability and a possible long-term trend in ocean temperature or salinity is critical to understanding the oceanographic response to climate change in the Arctic Ocean and could provide compelling evidence to support other observations in the Arctic that global warming has already begun.

该研究项目将在北极建立一个长期观测站，安装海洋系泊装置，发射漂流浮标，并进行温度和盐度的重复海洋横断面测量。 这些地点的海洋学观测将用于检查过去十年中经历快速变化的地区海洋和大气的长期变化。当前的变暖趋势可能预示着北冰洋海冰覆盖的融化，全球环流模型预测这是对全球变暖的反应。 确定海洋温度或盐度的变化和可能的长期趋势对于了解北冰洋气候变化的海洋学响应至关重要，并且可以提供令人信服的证据来支持北极的其他观测结果，即全球变暖已经开始。
