CHEMINI total dissolved iron concentrations from the EMSO-Azores observatory, 2011-2012

This dataset contains dissolved iron concentrations ((Fe(II) + Fe(III); µmol/l) acquired between July 2011 and March 2012 (n=1780) using the CHEMINI Fe, a CHEmical MINIaturized analyser (samples taken every 12 hours, without in situ calibration using a 25 µmol/l iron standard, Vuillemin et al., 2009). The sample inlet was positioned on the mussel bed at the base of the Tour Eiffel edifice of the Lucky Strike hydrothermal vent (1695 depth).CHEMINI Fe (CF1) was mounted on the TEMPO module which was itself connected to the SeaMON East node of the EMSO-Azores observatory.

该数据集包含2011年7月至2012年3月期间采集的溶解铁浓度数据[(Fe(II)+Fe(III); µmol/l)]，样本量n=1780。数据通过化学微型分析仪（CHEMical MINIaturized analyser）CHEMINI Fe获取，样本每12小时采集一次，未使用25 µmol/l铁标准液进行原位校准（Vuillemin et al., 2009）。样本入口置于Lucky Strike热液喷口埃菲尔铁塔结构底部的贻贝床处（深度1695米）。CHEMINI Fe（CF1）安装于TEMPO模块上，该模块连接至EMSO-亚速尔群岛观测站的SeaMON East节点。
