Eastern Gulf of Mexico glider deployment M69 (2017-01-03 -2017-01-13) – water quality variables

A Slocum G1 glider was deployed in the eastern Gulf of Mexico off Tampa Bay in January 2017. As the glider traversed its transit path, it made measurements at various depths from ~2 m to near the seafloor or up to 200 m. While the glider was deployed at sea, it surfaced and communicated to an onshore control station at predetermined intervals. A decimated selection of vehicle and science measurements was transmitted during these surface transmissions, and the relevant data became available through a USF web site. After the glider’s recovery at the end of the deployment, much of the complete measurement suite was downloaded from the vehicle, processed, and becomes available through the USF site, as well as a national data archive. The glider was deployed on 2017-01-03 at the 30 m isobath. It attempted to transit northwest along the Gulfstream Natural Gas Pipeline; however, southward currents prevented significant northward progress and eventually pushed the glider well to the south. It was recovered well south of Tampa Bay, off Longboat Key, on 2017-01-13. The raw measurements in this dataset include conductivity, temperature, depth, chlorophyll and gelbstoff fluorescence, and dissolved O2.

The suite of related datasets includes results from gliders M66, M69, M70, and M72.

2017年1月，一台斯洛库姆G1型水下滑翔机（Slocum G1 glider）被部署于墨西哥湾东部坦帕湾外海域。该滑翔机在沿航行路径行进期间，于约2米至近海底或最大200米的不同深度开展测量。部署期间，滑翔机会按预定间隔上浮，并与岸上控制站进行通信；每次上浮传输时，仅会发送经过筛选的载具与科学测量数据，相关数据可通过美国南佛罗里达大学（University of South Florida，简称USF）网站获取。部署结束并回收滑翔机后，完整的测量套件数据可从载具中下载并进行处理，相关成果除通过USF网站外，还可在国家数据档案库中获取。该滑翔机于2017年1月3日在30米等深线处部署，计划沿墨西哥湾流天然气管线向西北航行，但南向海流阻碍了其北进进程，最终将滑翔机推至更靠南的海域。最终该滑翔机于2017年1月13日在坦帕湾以南的长船礁外海域被回收。本数据集的原始测量数据包括电导率、温度、深度、叶绿素与黄色物质荧光，以及溶解氧。

本数据集关联的数据集还包括滑翔机M66、M69、M70及M72的观测成果。
