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.

用系泊装置监测北极西部边界流提供了一个完整的季节性周期的信息，这对于了解北极太平洋水的命运及其对生态系统的影响至关重要。 从系泊处获得了质量、热量和淡水的顺流和横流通量的精确测量。 这使得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。 该项目将在USCGC Healy上执行使命HLY 1402期间，在西经152°的北极边界流中恢复AON系泊。 在巡航期间，该小组还将对边界流进行水文测量，并为其他辅助项目进行额外的系泊工作。 最后，将使用仪器在152°W处重新部署系泊设备，允许部署两年。 这将把时间序列延长到2016年，从而产生11年的边界电流数据。 今年希利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。
