Inshore biogeochemical samples collected from Disko Fjord and Saqqarleq Fjord during August 2022@en

In parallel with a summertime cruise in Disko Bay (GLICE, August 2022), small vessels were used to sample the meltwater-rich areas at the entrance of Disko Fjord and in Saqqarleq Fjord (the southern branch of the Icefjord system). Discrete samples were collected from surface fjord waters and GO-FLO bottles were deployed down to 40 m to collect short profiles through the salinity stratified surface layer. Samples were retained for nutrients and dissolved trace metals. Surface water properties were determined using a YSI EXO-1 sensor to provide salinity, temperature, chlorophyll and turbidity data. A SBE 911plus CTD (Seabird) was used to conduct profiles down to 40 m. CTD bottle files are presented with discrete macronutrient and trace metal concentrations. Macronutrient samples were frozen and analyzed via autoanalyzer upon return to GEOMAR. Trace metal samples were filtered, acidified and analyzed upon return to GEOMAR after offline preconcentration using a seaFAST system.2022年8月GLICE航次（迪斯科湾夏季科考）期间，研究人员同步依托小型船舶，在迪斯科峡湾入口处及冰峡湾系统南分支萨卡尔莱克峡湾的富融水区域开展采样作业。研究人员从峡湾表层水体采集离散样本，并下放GO-FLO型采水器至40米水深，以获取盐度层化表层的短剖面采样数据。留存的样本用于营养盐与溶解态痕量金属的检测分析。利用YSI EXO-1型传感器测定表层水体参数，获取盐度、温度、叶绿素浓度与浊度数据。搭载Seabird公司生产的SBE 911plus型温盐深仪（CTD）开展了40米水深范围内的剖面测量作业。本数据集附带CTD采水瓶文件以及离散态大量营养盐与痕量金属浓度数据。大量营养盐样本经冷冻保存，返回GEOMAR（基尔亥姆霍兹海洋研究中心）后通过自动分析仪完成检测。痕量金属样本经过滤、酸化处理，使用seaFAST系统完成离线预富集后，返回GEOMAR进行分析检测。
