Collaborative Proposal: Annual Cycles of Nirtrate and Phytoplankton Stocks Using Optics at the North Pole Environmental Observatory

调查人员将在2004-2006年期间在北极环境观测站测量物理特性（电导率、温度）、硝酸盐浓度、色素生物量和光谱辐照度的时间变化。 将从两个高度的系泊传感器获取数据：50米（透光层底部）和100-120米（透光层）。 北冰洋中部的基线生物数据很少，这项研究将作出重要贡献。

The investigators will measure temporal variations in physical properties (conductivity, temperature), nitrate concentration, pigment biomass and spectral irradiance at the North Pole Environmental Observatory (NPEO) during 2004-2006. Data will be acquired from moored sensors at two levels: 50 m (base of the euphotic zone) and 100-120 m (disphotic zone). There is very little baseline biological data from the central Arctic Ocean, and this research will provide an important contribution.
