Submesoscale Processes and Lagrangian Analysis on the Shelf (SPLASH) surface drifter’s raw data in the Louisiana Bight from 2017-04-19 to 2017-09-18

Several hundred Consortium for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE) surface drifters were released during the Submesoscale Processes and Lagrangian Analysis on the Shelf (SPLASH) experiment in the Louisiana Bight from 2017-04-19 to 2017-09-18. The drifters were drogued at 0.5 m depth and reported their positions in real-time using SPOT GPS units nominally every 5 minutes for up to about 5 months. Some of the drifters were equipped with temperature and/or salinity sensors. This dataset contains the raw data, except for duplicate entries, out-of-range positions, and data before launch have been eliminated. This dataset was created by the CARTHE. This research was made possible by a grant from the Gulf of Mexico Research Initiative. A companion dataset with cleaned and interpolated trajectories is available under GRIIDC Unique Dataset Identifiers (UDI) R4.x265.000:0074 (DOI: 10.7266/n7-0pkg-hd54).

2017年4月19日至2017年9月18日，在路易斯安那湾开展的陆架亚中尺度过程与拉格朗日分析实验（Submesoscale Processes and Lagrangian Analysis on the Shelf, 简称SPLASH）中，共投放了数百台由环境中烃类运输高级研究联盟（Consortium for Advanced Research on Transport of Hydrocarbon in the Environment, 简称CARTHE）研发的表面漂流浮标。该批浮标在0.5米水深处配有沉子，通过SPOT全球定位系统（GPS）设备以标称每5分钟的频率实时传回位置数据，续航时长最长可达约5个月。部分浮标额外搭载了温度和/或盐度传感器。本数据集为原始观测数据，已完成重复条目、超出合理范围的位置数据以及投放前的无效记录的剔除工作，由CARTHE整理构建。本研究的开展得益于墨西哥湾研究倡议（Gulf of Mexico Research Initiative）的资助。配套的经过数据清洗与轨迹插值处理的轨迹数据集，可通过GRIIDC数据集唯一标识符（Unique Dataset Identifiers, 简称UDI）R4.x265.000:0074获取（数字对象标识符DOI: 10.7266/n7-0pkg-hd54）。
