Nitrate, nitrite, phosphate, dissolved silica concentrations (micromol/L) measured in the Beaufort Sea on multiple casts at 8 stations in 2009

Trace elements are chemicals that occur at very low concentrations, but play a role in the carbon cycle, marine ecosystems, and contaminant and climate processes of the oceans. This project is looking at the distribution and processes relating to trace elements in the Arctic Ocean. Specifically, how trace elements interact with changes in temperature, sea-ice cover, fresh water discharge, marine ecosystem structure and carbon sequestration capacity of the Arctic Ocean are being studied.微量元素（trace elements）是一类以极低浓度存在，却在海洋碳循环、海洋生态系统以及海洋污染物与气候过程中发挥关键作用的化学物质。本研究聚焦北冰洋内微量元素的分布特征与相关过程，具体而言，正探究微量元素与北冰洋温度变化、海冰覆盖变化、淡水径流输入、海洋生态系统结构以及碳汇能力之间的相互作用机制。
