Autonomous Time Series Measurement of 14C Primary Production on the Bermuda Test Bed Mooring

使用两个时间序列潜水孵化装置(TS-SID)，研究人员正在百慕大Testbd系泊上对碳14初级生产量进行自主高时间分辨率测量。这些测量寻求(1)生物光学模型的地面真实，BTM调查人员使用生物光学模型来估计系泊生物光学测量的初级生产力，以及(2)与百慕大大西洋时间序列研究(BATS)船舶初级生产力测量进行正面比较，以确认TS-SID函数的长期准确性，并直接量化浮游植物对短期扰动的反应。TS-SID构成了该地区碳14初级生产量的最高分辨率长期测量，可以解决时间混叠问题，以及较低频率研究对短期事件(如春季水华)的描述情况。由此产生的数据将对包含最大量子产率和光谱加权浮游植物吸收系数的复合项进行相互校准--将生物光学测量的入射光和叶绿素生物量转化为产量估计所必需的变量。

Using two Time Series - Submersible Incubation Devices (TS-SID), researchers are conducting autonomous high temporal resolution measurement of carbon-14 primary production on the Bermuda Testbd Mooring. These measurements seek (1) ground truthing of bio-optical models used by BTM investigators for estimating primary production from mooring bio-optical measurements, and (2) a head to head comparison with ship based Bermuda Atlantic Time-series Study (BATS) primary production measurements for confirming long term accuracy of TS-SID function, and providing direct quantification of phytoplankton response to short term perturbation. The TS-SID constitutes the highest resolution long term measurement of carbon-14 primary production made in this region, and can address issues of temporal aliasing and how well short term events (such as the spring bloom) are represented by the lower frequency study. Resulting data will intercalibrate a composite term encompassing maximum quantum yield and spectrally weighted phytoplankton absorption coefficient - variable necessary to translate bio-optically measured incident light and chlorophyll biomass into estimates of production.
