NRDA-processed CTD data from the F.G. Walton Smith in the Gulf of Mexico, Cruise 4 Leg 1, collected from 2011-04-20 to 2011-04-30, associated with the Deepwater Horizon Oil Spill event (NCEI Accession 0130280)

Conductivity Temperature and Depth (CTD) measurements were collected aboard the R/V F.G. Walton Smith to determine physical oceanographic parameters of the water column, and in some cases used to help guide sample collection as part of the Deepwater Horizon oil spill sampling effort. Temperature, conductivity/salinity, depth, dissolved oxygen, turbidity and fluorometry data were collected onboard the R/V F.G. Walton Smith. The final product is a series of NetCDF files containing every CTD cast that has been processed and quality checked.

本数据集使用研究船R/V F.G.沃尔顿·史密斯号采集的温盐深仪（Conductivity Temperature and Depth, CTD）测量数据，用于测定水体柱的物理海洋学参数；部分数据亦作为深水地平线漏油事故采样工作的组成部分，辅助指导样品采集。本次测量同步采集了温度、电导率/盐度、水深、溶解氧、浊度及荧光测量数据，所有数据均由该研究船完成采集。本数据集的最终产出为一系列网络通用数据格式（NetCDF）文件，涵盖所有经过处理与质量控制的CTD剖面测量数据。
