SmartBuoy observational network - Noordwijk 10

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 Noordwijk 10 SmartBuoy is located at 52.301 N, 4.303 E. It started logging
in September 2001 and finished in September 2001.

在智能浮标上，植物营养物质浓度的表面测量数据由两种仪器得出。NAS-3X现场营养分析仪每小时进行一次硝酸盐浓度的测量，而硝酸盐和硅酸盐浓度的低频（每日）测量则是通过WMS-2水样采集器收集并保存的水样在实验室分析得出的。利用测量叶绿素荧光的荧光计，每小时估算一次浮游植物浓度（生物量）。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、悬浮固体浓度以及光照穿透度的测量。数据通过ORBCOMM卫星遥测系统每两小时传输一次。位于北纬52.301度，东经4.303度的Noordwijk 10智能浮标自2001年9月开始记录，至同年9月结束。
