Organic matter and gel particles of Maria S. Merian cruise MSM85

The discrete biogeochemical measurements from RV Maria S. Merian MSM85 sampled for dissolved organic matter, microbial cell abundances and gel particles. The parameters include POC/PON, DOC/TDN, microbial cell abundances, gel particle concentrations like TEP and CSP. The samples were aquired within 5-2700 m of the Greenland Sea between 61 N to 77 N and 40 W to 4 W. The data was collected on board MSM85 from 27th July 2018-11th August 2019. The water collection occured using a CTD and laboratory methods varied by parameter. POC/PON was analysed using CHNS-O Elemental Analyser, DOC/TDN was analysed using TOC-VCSH, cell abundance (phytoplankton, bacteria, viral) was analysed using flow cytometery, gel particles were analysed colorimetrically using a spectrophotometer. The purpose of data collection was to understand spatial variability of organic mater and associated dynamics of the microbial loop.

本数据集包含RV Maria S. Merian号MSM85航次采集的离散生物地球化学测量数据，涵盖溶解有机物、微生物细胞丰度及凝胶颗粒等指标。具体参数包括POC/PON、DOC/TDN、微生物细胞丰度，以及TEP和CSP等凝胶颗粒浓度。采样区域位于格陵兰海，深度范围为5至2700米，地理坐标介于北纬61°至77°、西经40°至4°之间。数据采集时间为2018年7月27日至2019年8月11日，于MSM85航次期间在船上完成。水样通过CTD采集，实验室分析方法因参数而异：POC/PON采用CHNS-O元素分析仪测定，DOC/TDN使用TOC-VCSH分析仪检测，浮游植物、细菌及病毒的细胞丰度通过流式细胞术分析，凝胶颗粒则采用分光光度计比色法测定。本数据采集的目的在于揭示有机物的空间变异性及其相关微生物环的动态特征。
