Winter under-ice limnological and pigment data of the Great Whale River and its freshwater plume into Hudson Bay.

Winter conditions profoundly alter the limnological properties of lotic ecosystems. In 2019, from February 25 to March 1, we sampled the under-ice water column of the Great Whale River and its plume into Hudson Bay. This limnological and pigment dataset is complementary to an amplicon dataset (prokaryotes and microbial eukaryotes) and a metagenomic dataset that are available at the NCBI Sequence Read Archive (BioProject PRJNA999265 and PRJNA999354). It includes data for nutrients (total nitrogen and phosphorus), carbon (dissolved organic and inorganic), dissolved organic carbon characterization (SUVA254, SR, a320, S289), cell abundance measured by flow cytometry, total suspended sediment concentration, specific conductivity, snow depth, ice thickness, under-ice water depth, oxygen concentration, temperature and pigments determined by high-performance liquid chromatography.

冬季条件对流水生态系统的湖泊学特性产生深刻影响。2019年2月25日至3月1日，我们对大鲸河及其注入哈德逊湾的冰下水柱进行了采样。本湖泊学及色素数据集与NCBI序列读档（生物项目PRJNA999265和PRJNA999354）中可用的扩增子数据集（原核生物和微生物真核生物）以及宏基因组数据集相辅相成。它包含了营养素（总氮和磷）、碳（溶解有机和无机碳）、溶解有机碳特征（SUVA254、SR、a320、S289）、通过流式细胞术测量的细胞丰度、总悬浮固体浓度、比电导率、积雪深度、冰层厚度、冰下水深、氧浓度、温度以及通过高效液相色谱法确定的色素等数据。
