Oceanographic data and ROV dive-related multimedia and information collected during the EX1202L2 (Gulf of Mexico Exploration) expedition on NOAA Ship OKEANOS EXPLORER in the Gulf of Mexico from 2012-03-19 to 2012-04-11 (NCEI Accession 0087994)

This dataset contains oceanographic data collected in areas off the West Florida Shelf, around Desoto Canyon, in the vicinity of the Deepwater Horizon site and Mississippi Canyon. Daily schedules were split between daytime ROV operations (<4000 m) and nightly multibeam surveys. Nightly operations also included CTD casts and water-column experiments. This expedition identified and explored the diversity of benthic habitats in the region, located and characterized submerged cultural resources and their eligibility for the National Register of Historic Places, expanded tests of acoustic methods to detect gas seeps and measure flux, and improved capabilities to explore the water column.

本数据集收录了在佛罗里达西岸、德斯托科峡谷周边以及深水地平线遗址和密西西比峡谷海域所采集的海洋学数据。每日任务计划分为白天进行的无人遥控潜水器（ROV）作业（<4000米）与夜间进行的多波束测深调查。夜间作业还包括CTD 测深和水质柱实验。此次探险对区域内底栖生境的多样性进行了识别和探索，对水下文化遗产进行了定位和特征描述，并评估其是否符合国家历史登记名录的资格，扩展了声学方法在检测气体渗漏和测量通量方面的测试，并提升了探索水质柱的能力。
