Abstract. From 2014 to 2021, extensive monitoring of hydrodynamics was deployed within a variety of lagoons of New Caledonia during 6 tropical cyclone seasons. Globally, those coastal physical observations encompassed five different lagoons (four of which were never monitored before) and at least eight major atmospheric events ranging from tropical depression to category 4 cyclone. The main objectives were to characterize the processes at stake controlling hydrodynamics and hydrology of these lagoons (e.g ocean-lagoon exchanges, circulation, level dynamics, temperature and salinity variability) and capture their magnitude of change during extreme events. An additional objective was to build an adequate data set for assessment of high-resolution hydrodynamics models. Those field experiments took place within the PRESENCE project (PRESsures on coral Ecosystems of New CalEdonia) which aimed at building an efficient representation of the land-lagoon-ocean continuum of Grande Terre (main land) lagoons. Autonomous oceanographic instruments were moored at strategic locations to collect time-series of temperature, salinity, pressure, eulerian currents which characterize hydrodynamics at best. During field trips, whenever possible, lagrangian drifters releases and cross-shore hydrological profiles radials were additionally carried out. Surveys begun chronologically with SPHYNX campaign which lasted 15 months (December 2014 to February 2016) in the Hienghène-Touho lagoon followed with 5 months records in NOUMEA lagoon (December 2016 to April 2017). ELADE campaign in Poe lagoon encompassed 2 periods of measure (February to April 2018 and June to August 2018). In Koumac lagoon, CADHYAK survey was carried out between December 2019 until the end of May 2020 and finally, data have been recorded continuously for 9 months in Moindou lagoon (NEMO) (September 2020 to April 2021). In addition to characterize these lagoons, this data set stresses out some important features and processes, such as the presence of internal waves on reef slopes, wave-driven fluxes over reef barrier and exchanges through passes. It also contains the signatures of strong events materialized by surges, thermal drops inside lagoons or massive flash flood plumes dispersion. Raw data sets were processed, quality-controlled and validated, and processed files are publicly available in dedicated repositories on Seanoe in NetCDF format.

各种珊瑚礁泻湖中的水动力和水文过程：新喀里多尼亚 6 个气旋季节的实地观察

摘要。从 2014 年到 2021 年，在 6 个热带气旋季节期间，在新喀里多尼亚的多个泻湖中部署了广泛的流体动力学监测。在全球范围内，这些沿海物理观测包括五个不同的泻湖（其中四个以前从未被监测过）和至少八个主要的大气事件，从热带低气压到 4 类气旋。主要目标是描述控制这些泻湖的水动力和水文的关键过程（例如海洋-泻湖交换、环流、水位动力学、温度和盐度变化），并捕捉极端事件期间它们的变化幅度。另一个目标是建立一个足够的数据集来评估高分辨率流体动力学模型。这些现场实验是在 PRESENCE 项目（新喀里多尼亚珊瑚生态系统的压力）中进行的，该项目旨在建立一个有效的代表 Grande Terre（主要陆地）泻湖的陆地-泻湖-海洋连续体。自主海洋学仪器停泊在战略位置，以收集温度、盐度、压力、欧拉流的时间序列，这些数据充其量是流体动力学的特征。在实地考察期间，尽可能额外进行拉格朗日漂流释放和跨岸水文剖面径向线。调查按时间顺序开始，SPHYNX 活动在 Hienghène-Touho 泻湖持续了 15 个月（2014 年 12 月至 2016 年 2 月），随后在 NOUMEA 泻湖（2016 年 12 月至 2017 年 4 月）持续了 5 个月的记录。Poe 泻湖的 ELADE 活动包括 2 个测量期（2018 年 2 月至 4 月和 2018 年 6 月至 8 月）。在 Koumac 泻湖，CADHYAK 调查于 2019 年 12 月至 2020 年 5 月底期间进行，最终在 Moindou 泻湖（NEMO）（2020 年 9 月至 2021 年 4 月）连续记录了 9 个月的数据。除了描述这些泻湖的特征外，该数据集还强调了一些重要的特征和过程，例如礁坡上存在内波、礁石屏障上的波浪驱动通量和通道交换。它还包含由潮汐、泻湖内的热下降或大规模的山洪羽流扩散所体现的强烈事件的特征。原始数据集经过处理、质量控制和验证，和处理过的文件在 Seanoe 的专用存储库中以 NetCDF 格式公开提供。此处提供了各个数据集的链接 (DOI)。
