We request a portable and towable current profiler to measure near surface currents from small boats in coastal seas such as the St. Lawrence Estuary, the Saguenay Fjord and various bays surrounding the Gulf of St. Lawrence. Obtaining such current measurements in the surface layer and photic zone of the coastal ocean is central to just about all oceanographic researches carried out in coastal seas, whether it be to monitor plankton, nutrient, sediment or pollutant transports or to support fundamental research on geophysical fluid dynamics and ocean turbulence. This instrument will support applied as well as fundamental research and training programs. On the applied side, it will be used, for example, during Summer 2017 to map the currents in the Bay of Sept-îles as part of the Canadian Healthy Ocean Network initiative in order to better understand antrhopogenic environmental impacts of pollutants an sediment transport and dispersal in our coastal zones. On the fundamental side, it will be used during Summer 2017 to support an international Canada-France-Netherlands research project to study the generation and propagation of very large (> 10 m height) underwater waves recently found in the Saguenay Fjord. These researches will lead to better management of coastal seas and help protect the environment as well as improve our fundamental understanding of natural flows and increase Canada's intellectual merit and scientific creativity.

我们需要一种便携式和可拖曳的水流剖面仪来测量沿海海域的小船近表面水流，如圣劳伦斯河口，萨格奈峡湾和圣劳伦斯湾周围的各种海湾。无论是监测浮游生物、营养物、沉积物或污染物的输送，还是支持地球物理流体动力学和海洋湍流的基础研究，在沿海海洋的表层和光带获得这种电流测量，对几乎所有在沿海海域开展的海洋学研究都至关重要。该仪器将支持应用以及基础研究和培训计划。在应用方面，例如，作为加拿大健康海洋网络倡议的一部分，它将在2017年夏季用于绘制Sept- les湾的洋流图，以便更好地了解污染物和沉积物在我们沿海地区的运输和扩散对环境的影响。在基础方面，它将在2017年夏季用于支持加拿大-法国-荷兰的一个国际研究项目，研究最近在Saguenay峡湾发现的非常大（bbb10米高）水下波浪的产生和传播。这些研究将有助于更好地管理沿海海域，帮助保护环境，提高我们对自然流动的基本认识，增加加拿大的智力价值和科学创造力。
