Monitoring the Western Arctic Boundary Current in a Warming Climate: Mooring activities and Hydrographic Sampling in 2014

通过系泊监测北极西部边界洋流，可以提供一个完整季节周期的信息，这对于了解北极太平洋水域的命运及其对生态系统的影响至关重要。从系泊中获得了沿流和跨流的质量、热量和淡水通量的精确测量。这允许物理环境和生态系统之间的因果关系，从营养动态到更高的热带地区。在USCGC Healy的HLY1402任务期间，该项目将在152°W的北极西部边界洋流中恢复AON系泊。在航行期间，船队亦会进行边界水流的水文测量，并为其他附属项目进行额外的系泊工作。最后，将在152°W处重新部署系泊，使用可部署两年的仪器。这将把时间序列延长到2016年，从而得到11年的边界流数据。今年希利号游轮上的科学派对将包括三名研究生、一名本科生和一名来自MATE实习项目的参与者。这将为这些年轻的研究人员在各个领域提供宝贵的海上经验。

Monitoring the western Arctic boundary current with a mooring provides information over a complete seasonal cycle at a location that is critical for understanding the fate of the Pacific water in the Arctic and its impact on the ecosystem. Accurate measures of along-stream and cross-stream fluxes of mass, heat, and freshwater are obtained from the mooring. This allows for causal relationships between the physical environment and the ecosystem, ranging from nutrient dynamics up to higher tropics. This project will recover an AON mooring in the western Arctic boundary current at 152°W during mission HLY1402 on the USCGC Healy. During the cruise the team will also carry out a hydrographic survey of the boundary current and do additional mooring work for other ancillary projects. Finally, a mooring will be re-deployed at 152°W using instrumentation that allows for a two-year deployment. This will extend the timeseries until 2016, resulting in 11 years of data from the boundary current. The science party on the Healy cruise this year will include three graduate students, one undergraduate student, and a participant from the MATE internship program. This will provide valuable at-sea experience for these young researchers in a variety of areas.
