Abstract. Over a hundred of experiments were realised between 1998 and 2022 in the Mediterranean Sea using surface Lagrangian drifters, at coastal and offshore level. Raw data were initially unified and pre-processed manually by eliminating spikes and wrong positions or date/time information. The integrity of the received data packages was checked, and incomplete ones were discarded. Deployment information was retrieved from an initial excel database and campaign notes for each drifter and integrated into the PostgreSQL database, realised and maintained by the National Institute of Oceanography and Applied Geophysics (OGS) in Trieste (IT). This database also collects a variety of metadata about the drifter model, project, owner and operator. Subsequently data were processed using standard procedures of editing and quality control developed for the OGS Mediterranean drifter dataset to remove spikes generated by malfunctioning of the sensors and obtain files with common characteristics. Drifter data and plots of each track were also visually checked to remove any point not identified by the automatic procedure and clearly erroneous. Drifters’ trajectories were split into two or more segments that have been considered as different deployments, in case of specific drifters' behaviours. Data were interpolated at defined time intervals to temporarily unify tracks. From the original 138 experiments, a dataset of 204 tracks was obtained, available from the public open-access repository in SEANOE (SEA scieNtific Open data Edition) at https://doi.org/10.17882/90537 (Ribotti et al., 2022).

地中海漂流者数据集：1998–2022

摘要。1998 年至 2022 年间，在地中海使用地表拉格朗日漂流者在沿海和近海水平进行了一百多项实验。原始数据最初是通过消除峰值和错误位置或日期/时间信息来手动统一和预处理的。检查接收到的数据包的完整性，丢弃不完整的数据包。部署信息从最初的 excel 数据库和每个漂流者的活动记录中检索，并集成到 PostgreSQL 数据库中，由位于的里雅斯特 (IT) 的国家海洋学和应用地球物理研究所 (OGS) 实现和维护。该数据库还收集了有关漂流者模型、项目、所有者和运营商的各种元数据。随后使用为 OGS 地中海漂流者数据集开发的标准编辑和质量控制程序处理数据，以消除传感器故障产生的尖峰并获得具有共同特征的文件。还目测检查了每个轨道的漂移数据和图，以删除任何未由自动程序识别且明显错误的点。漂移者的轨迹被分成两个或多个部分，这些部分被认为是不同的部署，以防特定漂移者的行为。以定义的时间间隔对数据进行插值，以暂时统一轨迹。从最初的 138 个实验中，获得了 204 个轨道的数据集，可从 SEANOE（SEA 科学开放数据版）中的公共开放存取存储库获取，网址为 https://doi.org/10.17882/90537（Ribotti 等，2022 ）。
