Limnological and pigment data from the Great Whale River and surrounding surface waters.

Northern terrestrial ecosystems are undergoing rapid transformation, potentially affecting the chemistry and microbial community structure in rivers flowing through them. From 2 to 10 August 2018, we sampled surface waters from the Great Whale River (GWR), three of its tributaries (Coats, Denys, and Kwakwatanikapistikw rivers), the GWR plume flowing into Hudson Bay, and the Sasapimakwananistikw River. This limnological and pigment dataset is complementary to an amplicon dataset (prokaryotes and microbial eukaryotes) available at the NCBI Sequence Read Archive (BioProject: PRJNA744875). It includes data for nutrients (total nitrogen and phosphorus, total dissolved nitrogen), carbon (dissolved organic and inorganic), dissolved organic carbon characterization (SUVA254, SR, a320, S289), cell abundance measured by flow cytometry, salinity, total suspended sediment concentration, and pigments determined by high-performance liquid chromatography.

北方陆地生态系统正经历快速转变，这可能会对流经其中的河流的化学特征与微生物群落结构造成影响。2018年8月2日至10日，我们对大鲸河（Great Whale River, GWR）及其三条支流（科茨河、丹尼斯河与夸克瓦塔尼卡皮斯蒂克瓦河）、流入哈得逊湾的大鲸河羽流，以及萨萨皮马卡瓦纳尼斯蒂克瓦河开展了地表水采样。本湖沼学与色素数据集可与公开于美国国家生物技术信息中心（National Center for Biotechnology Information, NCBI）序列读取档案（Sequence Read Archive, SRA，生物项目编号：PRJNA744875）的扩增子数据集（涵盖原核生物与微生物真核生物）形成互补。本数据集包含如下检测数据：营养盐（总氮、总磷、总溶解氮）、碳组分（溶解有机碳与溶解无机碳）、溶解有机碳表征参数（254 nm比紫外吸收值SUVA254、光谱斜率SR、320 nm吸光度a320、289 nm光谱斜率S289）、流式细胞术检测的细胞丰度、盐度、总悬浮泥沙浓度，以及经高效液相色谱法（high-performance liquid chromatography, HPLC）测定的色素含量。
