SmartBuoy observational network - Oyster Grounds

On the SmartBuoy, surface measurements of plant nutrient concentrations are
derived from two instruments. The NAS-3X in-situ nutrient analyser takes
hourly measurements of nitrate concentration, while lower frequency (daily)
measurements of nitrate and silicate concentration are derived from laboratory
analysis of water samples collected and preserved by the WMS-2 water sampler.
An estimate of phytoplankton concentration (biomass) is obtained twice per
hour using a fluorometer measuring chlorophyll fluorescence. To aid
interpretation of these data, SmartBuoy also takes measurements of
conductivity, temperature, suspended sediment concentration, light penetration
with the ESM2 logger. Data are telemetered every two hours using ORBCOMM
satellite telemetry.

The Oyster Grounds SmartBuoy is located at 54.414 N, 4.0417 E. It started
logging in March 2006 and is still operational.

在智能浮标上，植物营养浓度表面测量数据由两种仪器获得。NAS-3X原位营养分析仪每小时测量硝酸盐浓度，而硝酸盐和硅酸盐浓度的较低频率（每日）测量则通过WMS-2水样采集器收集并保存的水样进行实验室分析得出。利用测量叶绿素荧光的荧光计，每小时获得两次浮游植物浓度（生物量）的估计值。为了辅助这些数据的解读，智能浮标还使用ESM2记录仪进行电导率、温度、悬浮物浓度和光穿透度的测量。数据通过ORBCOMM卫星遥测，每两小时传输一次。Oyster Grounds智能浮标位于北纬54.414度，东经4.0417度。自2006年3月开始记录，至今仍在运行。
