Concentrations of trace metals and dissolved macronutrients and CTD sensor data from four cruises in the Bermuda Atlantic Time-series Study (BATS) region in March, May, August and November 2019

These data include the concentrations of trace metals (dissolved and soluble iron, dissolved and soluble manganese, dissolved aluminum) and dissolved macronutrients (nitrate+nitrite, phosphate, reactive silicate) determined in water-column samples collected using a trace-metal clean CTD rosette, or an inflatable dinghy, during four cruises in the Bermuda Atlantic Time-series Study (BATS) region in March, May, August and November 2019. Also presented are CTD sensor data (pressure, temperature, salinity, chlorophyll fluorescence, dissolved oxygen) and derived variables (water depth, density) corresponding to the CTD-rosette bottle samples. The samples and associated data were collected for the BAIT project (GEOTRACES Process Study GApr13). Post-cruise sample analyses were performed at Old Dominion University (trace metals) and the Bermuda Institute of Ocean Sciences (macronutrients).本数据集涵盖2019年3月、5月、8月及11月于百慕大大西洋时间序列研究（Bermuda Atlantic Time-series Study，简称BATS）海域开展的四次科考航次中，采用痕量金属洁净型CTD采水器阵列（CTD rosette）或充气橡皮艇采集的水柱样品的检测数据，检测指标包括痕量金属（溶解态与可溶性铁、溶解态与可溶性锰、溶解态铝）以及溶解态常量营养盐（硝酸盐+亚硝酸盐、磷酸盐、活性硅酸盐）。 本数据集同时包含对应CTD采水器瓶样的CTD传感器数据（压力、温度、盐度、叶绿素荧光、溶解氧）及衍生变量（水深、密度）。 本数据集的样品及配套数据均为BAIT项目（GEOTRACES过程研究GApr13）所采集。 航次后样品分析分别在奥多明尼昂大学（Old Dominion University）与百慕大海洋科学研究所（Bermuda Institute of Ocean Sciences）完成，其中奥多明尼昂大学负责痕量金属检测，百慕大海洋科学研究所负责常量营养盐检测。
