Slocum glider and turbulence data collected by TAMU glider unit 541 aboard R/V Point Sur during the GoMix II cruise (PS18-06) in the northern Gulf of Mexico from 2017-08-21 to 2017-09-09

This dataset contains CTD and turbulence data from the TAMU Slocum glider Unit 541 during the GoMix II cruise (R/V Point Sur, PS18-06) from 2017-08-21 to 2017-09-09. The experimental site is on the continental slope of the northern Gulf of Mexico, next to the Deepwater Horizon spill site. GoMix is a three year project with the goal of understanding the mechanisms, spatial inhomogeneity, and temporal intermittency of boundary mixing along the Northern Deepwater Gulf. The glider used was a Deep G2 Slocum glider equipped with a Rockland Scientific MicroRider turbulence sensing package. The glider was deployed on the shelf and instructed to fly cross-slope transects between approximately 200 to 1000 water depth. It was operated in yo-yo mode and collected data from 20 m (the base of the surface mixed layer) to ~15 m above the bottom. Temperature, salinity, dissolved oxygen, CDOM, chlorophyll, and turbidity were collected by the CTD aboard the glider. The turbulence package only collected data from 2017-09-02 to 2017-09-07. The dataset contains binary and exported ASCII data flight (DBD) and science (EBD) data, as well as output from the MicroRider in binary and Matlab format. Dissipation was calculated for both upward and downward profiles. Those dissipation data are contained in a structure named diss*, where * indicates the profile number.

本数据集包含2017年8月21日至2017年9月9日期间，德克萨斯农工大学（TAMU）Slocum滑翔机541号在GoMix II航次（R/V Point Sur，航次编号PS18-06）中采集的CTD数据与湍流数据。实验区域位于墨西哥湾北部大陆坡，毗邻深水地平线（Deepwater Horizon）溢油事故现场。GoMix是一项为期三年的研究项目，旨在揭示墨西哥湾北部深水区边界混合的机制、空间非均质性及时间间歇性特征。所用滑翔机为Deep G2型Slocum滑翔机，搭载了Rockland Scientific公司的MicroRider湍流传感组件。该滑翔机于陆架区域投放，按指令沿跨陆坡断面飞行，作业水深范围约为200至1000米。滑翔机以“悠悠球”模式（yo-yo mode）运行，数据采集范围从海面混合层底部（水深20米）至海底以上约15米处。滑翔机搭载的CTD采集了温度、盐度、溶解氧、有色溶解有机物（CDOM）、叶绿素及浊度数据。湍流传感组件的有效数据采集时段为2017年9月2日至2017年9月7日。本数据集包含二进制及导出的ASCII格式飞行数据（DBD）与科学数据（EBD），以及MicroRider组件生成的二进制格式和Matlab格式输出数据。研究人员针对上升与下降剖面均计算了耗散率，相关数据存储于名为diss*的结构中，其中*代表剖面编号。
