Physical, chemical, and bio-optical data collected from Seaglider SG157 during IOOS OSU sampling on Trinidad Head Line in the North Pacific Ocean deployed from 2014-11-16 to 2015-03-09 (NODC Accession 0125046)

Seaglider is a buoyancy driven autonomous underwater vehicle (AUV) developed by scientists and engineers at the University of Washington's School of Oceanography and Applied Physics Laboratory. Seagliders are designed to glide from the ocean surface to a programmed depth and back while measuring temperature, salinity, depth-averaged current, and other quantities along a saw tooth trajectory through the water. Seaglider has entered wide use in scientific deployments. They are designed for missions in range of several thousand kilometers and durations of many months. Seagliders are commanded remotely and report their measurements in near real time via wireless telemetry.

海滑翔机（Seaglider）是由华盛顿大学海洋学院与应用物理实验室的科研人员与工程师研发的浮力驱动型自主水下航行器（autonomous underwater vehicle，AUV）。海滑翔机的设计目标是在海面与预设深度之间往复滑翔，同时沿锯齿状水下航迹采集温度、盐度、深度平均海流及其他海洋环境参数。该型水下航行器已在海洋科学考察布放作业中得到广泛应用，其可支持数千公里航程与长达数月的连续科考任务，且可通过远程指令操控，借助无线遥测技术近乎实时地回传采集到的测量数据。
