Glider Repeat Surveys of Eastern Boundary Currents off Washington

0095414埃里克森这个项目的目的是展示滑翔机在观测边界流方面的有效性，并描述在西风漂流末端的东部边界流演变的年度周期。海滑器是一种小型、可重复使用的自动驾驶工具，旨在从海面滑行至200米深并返回，同时收集物理、化学和生物光学特性的剖面。两架海滑机将在华盛顿海岸外长达7.5个月的连续任务中部署，以解决加州/阿拉斯加洋流系统的季节性周期。所有的数据，大约1000个温度和盐度分布将被近乎实时地传输，这样就可以监测滑翔机的进度和当前的海洋状况。氧气和生物光学传感器也将安装在滑翔机上。这项拟议的工作旨在向学习在很长一段时间内观察边界流迈进一步。

0095414 EriksenThis project is aimed at demonstrating the effectiveness of gliders to observe boundary currents and describe an annual cycle of eastern boundary current evolution at the terminus of the West Wind Drift. Seagliders are small, reusable autonomous vehicles designed to glide from the ocean surface to as deep as 200 m and back while collecting profiles of physical, chemical and bio-optical properties. Two Seagliders will be deployed in successive missions up to 7.5 months long off the Washington coast to resolve the seasonal cycle of the California/Alaska Current system. All the data, about a thousand profiles of temperature and salinity will be transmitted in near-real time so that the progress of the gliders and current oceanic conditions can be monitored. Oxygen and bio-optical sensors will also be on the gliders. The work proposed is intended as a step forward toward learning to observe boundary currents over long time periods.
