Gironde Estuary Mouth MEasurement Stations (GEMMES)

in the framework of the anr amorad project, the meteor cruises (grasso, 2017) aimed at deploying the ‘gironde estuary mouth measurement stations’ (gemmes) to measure hydrodynamics and sediment dynamics at the mouth of the gironde estuary and on the west gironde mud patch (sw france, bay of biscay). measurements were carried out between november 2016 and december 2017: i) from a buoy station around 20-m water depth (gemmes-20), collecting sub-surface data of temperature, salinity and turbidity; and ii) a benthic station around 40-m water depth (gemmes-40), collecting data of current velocity and turbidity. bottom and surface water samples were regularly collected to calibrate turbidity measurements to spm concentrations.

在ANR AMORAD项目框架下，‘流星巡航’（Grasso，2017）旨在部署‘吉罗讷河湾口测量站’（GEMMES），以测量吉罗讷河湾口及西吉罗讷河泥质浅滩（法国西南部，比斯开湾）的流体动力学和泥沙动力学。测量工作于2016年11月至2017年12月间进行：i）在约20米水深处的浮标站（GEMMES-20）收集亚表层温度、盐度和浊度数据；ii）在约40米水深处的底栖站（GEMMES-40）收集流速和浊度数据。定期采集底部和表层水样，以校准浊度测量至SPM浓度。
