SGER: A Winched Profiler for Upper Ocean Measurements in Multiple Oceanic Environments

知识优势：对于许多海洋学应用来说，捕捉上层海洋过程是很重要的。然而，由于实际原因（繁忙的船舶交通、捕鱼、海冰和水面波浪活动），大多数系泊点没有延伸到海面。在这个项目中，一名WHOI科学家将能够参加即将到来的（2006年夏季）研究巡航，在哈德逊海峡放置一台绞车剖面仪。这个地区在冬季有漂浮的海冰，并且水流湍急，这使得它对上层海洋系泊测量来说是一个危险的环境。该海峡的上层海洋也是北大西洋重要的淡水流量（表面捕获）的位置，因此测量对于了解气候系统非常重要。更广泛的影响：一旦经过测试，该仪器将通过在剖面仪上添加传感器而在海洋学的所有领域中发挥作用。此外，该项目还将从一个以前没有测量过的气候敏感地区收集数据。

Intellectual Merit: Upper ocean processes are important to capture for many oceanographic applications. However, most moorings do not extend to the sea surface for practical reasons (heavy ship traffic, fishing, sea-ice and surface wave activities). In this project, a WHOI scientist will be able to participate in an upcoming (summer 2006) research cruise, to place a winched profiler in Hudson Strait. This region has floating sea-ice during the winter months and has swift currents, making it a risky environment for upper-ocean moored measurements. The upper ocean in this Strait is also the location of an important (surface-trapped) freshwater flux to the North Atlantic and therefore the measurements are important for understanding the climate system. Broader Impacts:Once tested, this instrument will be useful in all fields of oceanography by adding sensors to the profiler. In addition, the project will collect data from a climate-sensitive region that has previously not been measured.
