Nickel and copper concentrations in near-bottom water during METEOR cruises M136 and M137

Trace metal and nutrient concentration gradients in near-bottom waters were determined on research vessel meteor cruises M136 and M137 in April and May 2017. Water samples were collected at 0.5, 1.0, 2.0, 3.0 and 4.0 m above the seafloor using perestaltic pumps attached to a benthic lander. Trace metal concentrations were determined by ICP-MS. The data are used to evaluate the fate of sediment-derived trace metals in the lower water column across the Peruvian oxygen minimum zone.

2017年4月与5月，科研人员搭乘“流星号”（Meteor）科考船执行M136、M137航次，于秘鲁近海测定了近底水体中的痕量金属与营养盐浓度梯度。本研究使用安装在海底着陆器（benthic lander）上的蠕动泵，在海底上方0.5、1.0、2.0、3.0及4.0米处采集水样。痕量金属浓度通过电感耦合等离子体质谱仪（Inductively Coupled Plasma Mass Spectrometry, ICP-MS）完成测定。本数据集旨在评估横穿秘鲁氧最低区（Peruvian oxygen minimum zone）的下层水体中，沉积物来源痕量金属的迁移归宿。
