Since 2000, and for the following 20 years, hydrological data of the Mediterranean Sea, with a particular focus on the western and central Mediterranean sub-basins, have been acquired to study the hydrodynamics at both coastal and open sea scales. In total, 1468 hydrological casts were realized in 29 oceanographic cruises planned due to scientific purposes linked with funding research projects but were also sometimes driven by sea conditions and type of vessel. After accurate quality assurance and control, following standard procedures, all hydrological data were included in four online public open-access repositories in SEANOE (SEA scieNtific Open data Edition), available from https://doi.org/10.17882/87567 (Ribotti et al., 2022). Hydrological and dissolved oxygen data are always present in all of the datasets, whereas pH, fluorescence, turbidity, and chromophoric dissolved organic matter (CDOM) are available just for some cruises. Samplings were carried out mainly along transects, with some repetition over the years. The results of two data analyses, i.e., staircase systems in the Tyrrhenian Sea and in the Algero-Provençal sub-basin and spreading of the Western Mediterranean Transient, are mentioned.

地中海 21 年的水文数据采集：质量、可用性和研究

自 2000 年以来，以及随后的 20 年，获得了地中海水文数据，特别关注地中海西部和中部次流域，以研究沿海和公海尺度的水动力。出于与资助研究项目相关的科学目的，计划进行的 29 次海洋巡航中总共实现了 1468 次水文模型，但有时也受到海况和船舶类型的驱动。经过准确的质量保证和控制，按照标准程序，所有水文数据都包含在 SEANOE（SEA 科学开放数据版）的四个在线公共开放存取存储库中，可从 https://doi.org/10.17882/87567（Ribotti 等等人，2022）。水文和溶解氧数据始终存在于所有数据集中，而 pH、荧光、浊度、发色溶解有机物 (CDOM) 仅适用于某些游轮。采样主要沿样带进行，多年来有一些重复。提到了两个数据分析的结果，即第勒尼安海和阿尔及利亚-普罗旺斯次盆地的阶梯系统和西地中海瞬变的扩展。
