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.

0095414 Eriksen该项目旨在展示滑翔机观察边界流的有效性，并描述西风漂流终点处东部边界流演变的年度周期。海洋滑翔机是小型、可重复使用的自动驾驶车辆，设计用于从海洋表面滑翔至 200 m 深处并返回，同时收集物理、化学和生物光学特性的概况。两架海洋滑翔机将在华盛顿海岸连续执行长达 7.5 个月的任务，以解决加利福尼亚/阿拉斯加海流系统的季节性周期问题。所有数据，大约一千个温度和盐度分布图都将近乎实时地传输，以便可以监测滑翔机的进展和当前的海洋状况。滑翔机上还将配备氧气和生物光学传感器。拟议的工作旨在向学习长时间观察边界电流迈出一步。
