PacIOOS Ocean Gliders: SeaGlider 139: Mission 8

As a part of PacIOOS, ocean gliders provide very detailed information about the physical and chemical condition of the waters around the Hawaiian Islands. Additionally, these data get used in computer models to make predictions about currents. Ocean gliders are small, free-swimming, unmanned vehicles that can cruise the ocean for several months gathering information about the temperature, salinity, and other water properties between the surface and 1000 m depth. A pressure sensor on the glider is able to record the depth throughout the dive. Because gliders are unmanned, they communicate with scientists on land when they are at the surface using an antenna on the end of the glider. The SeaGlider autonomous underwater vehicle (AUV) was designed at the University of Washington (UW) Applied Physics Laboratory (APL). These data are taken from Mission 8 of SeaGlider 139.

history=2010-07-11T00:00:00Z Glider refurbished at SOEST Ocean Gliders Facility.
2010-07-28T00:00:00Z Deployed S. of Oahu by Pier 45 Boston Whaler.
2010-11-11T00:00:00Z Recovered S. of Oahu by OTG Safe boat: nearing end of battery life, deployed: 107 days.
2022-11-17T23:30:00Z Dataset identifier modified from "sg139_8" to "sg_139_008" to better match PacIOOS naming conventions.
2023-02-07T18:35:00Z Renamed "depth" variable to "altitude" per the ERDDAP convention for negative ocean depths (positive=up). Added "dive_number" variable.

作为PacIOOS项目的一部分，海洋滑翔机提供了关于夏威夷群岛周围水域物理和化学状态的详尽信息。此外，这些数据被用于计算机模型，以预测水流。海洋滑翔机是小型、自由游动的无人驾驶车辆，能够在海洋中航行数月，收集关于从海面到1000米深度之间的水温、盐度及其他水性质的资料。滑翔机上的压力传感器能够记录潜水过程中的深度。由于滑翔机无人驾驶，当它们浮出水面时，会通过滑翔机末端的天线与陆地上的科学家进行通信。SeaGlider自主水下航行器（AUV）由华盛顿大学（UW）应用物理实验室（APL）设计。这些数据来自SeaGlider 139号的第8次任务。
