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

使用系泊设备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，该位置对于了解太平洋水在北极的命运及其对生态系统的影响至关重要。从系泊设备上可以获得质量、热量和淡水的顺流和横流通量的准确测量。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。该项目将在USCGC Healy上执行HLY1402任务期间，在152°W的北极西部边界海流中恢复一个Aon系泊。在巡航期间，该小组还将对边界海流进行水文测量，并为其他附属工程进行额外的系泊工作。最后，将使用允许两年部署的仪器重新部署152°W的系泊设备。这将把时间序列延长到2016年，产生来自边界洋流的11年数据。今年Healy邮轮上的科学派对将包括三名研究生，一名本科生，以及一名来自Mate实习计划的参与者。这将为这些在不同领域的年轻研究人员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.
