CADHYAK surveys : Field observations of hydrodynamics functioning of Koumac Lagoon (New Caledonia - North Province)

koumac lagoon has been instrumented over a period of 6 months (from december 2019 to may 2020) in order to characterized its hydrodynamics functioning. this lagoon is surrounding by mining activities that may affect and damage its ecosystem. nineteen sensors have been deployed on moorings to measure and quantify water circulation and exchanges between land, lagoon and ocean (current, temperature, salinity and pressure). ctd profiles have also been performed to observe spatial extent and stratification of water bodies. during the sampling period, two major meteorological events occurred, uesi cyclone (11th february 2020) and gretel tropical depression (15th march 2020), which have significantly impacted hydrodynamics.sampling strategy available on sextant.- marine geographic information system.more informations on presence project.

库玛克潟湖自2019年12月至2020年5月（为期六个月）进行了仪器监测，以对其水文动力功能进行表征。该潟湖周边存在矿业活动，可能对其生态系统造成影响和损害。在浮标上部署了十九个传感器，以测量和量化陆地、潟湖与海洋之间的水循环和交换（包括流速、温度、盐度和压力）。同时，还进行了CTD剖面测量，以观察水体空间分布和分层状况。在采样期间，发生了两次主要气象事件，即乌塞斯气旋（2020年2月11日）和格雷特尔热带低压（2020年3月15日），这些事件对水文动力产生了显著影响。采样策略可在六分仪上获得。此外，还提供了海洋地理信息系统相关信息。关于存在项目的更多信息可查阅。
