SmartBuoy observational network - Celtic Deep

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 Celtic Deep SmartBuoy is located at 51.2495 N, 6.0818 W It started logging
in May 2009 and finished in February 2012.

在智能浮标（SmartBuoy）上，植物营养浓度之表面测量值由两种仪器获得。NAS-3X现场营养分析器负责每小时对硝酸盐浓度进行测量，而硝酸盐和硅酸盐浓度之较低频率（每日）测量值则源自于WMS-2水样采集器所采集并保存之水样之实验室分析。利用测定叶绿素荧光之荧光计，每小时对浮游植物浓度（生物量）进行两次估算。为辅助对这些数据之解读，智能浮标还通过ESM2记录仪对电导率、温度、悬浮颗粒浓度、光穿透度进行测量。数据每两小时通过ORBCOMM卫星遥测进行传输。位于北纬51.2495度，西经6.0818度的凯尔特深海智能浮标自2009年5月开始记录，并于2012年2月结束。
