Collaborative Research: Annual Cycles of Nitrate and Phytoplankton Stocks using Optics at the North Pole Environmental Observatory

研究人员将在2004-2006年期间在北极环境观测站（NPEO）测量物理性质（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。数据将从两个高度的系泊传感器获取：50米（光区底部）和100-120米（双光区）。来自北冰洋中部的基线生物学数据非常少，这项研究将提供重要的贡献。

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.
