The Lake Bolshie Hruslomeny is located on the shores of the Kandalaksha Bay of the White Sea, North European Russia. This lake, formed from the sea bay and still retaining the subsurface connection with the sea, is meromictic, with a fresh oxygenated upper layer and an anoxic brackish hypolimnion with high concentrations of methane and hydrogen sulphide. To characterize the microbial communities involved in the carbon and sulfur cycles in the lake, we sequenced the metagenome of a water sample collected at the chemocline level. At the phylum level, , , and were the most numerous groups. The obtained data will help investigate the diversity and ecological role of the microbial community in the Lake Bolshie Hruslomeny and provide insight into the biogeochemical processes in subarctic lakes. The raw sequencing data is available from the NCBI Sequence Read Archive (SRA) database under the BioProject PRJNA503531.
大赫鲁斯洛梅尼湖位于俄罗斯北欧地区白海坎达拉克沙湾的岸边。这个由海湾形成且仍与大海保持地下连接的湖泊是半混合湖，有一个富含氧气的淡水上层和一个缺氧的微咸下层，其中甲烷和硫化氢浓度很高。为了表征参与该湖碳和硫循环的微生物群落，我们对在化学跃层水平采集的水样进行了宏基因组测序。在门水平上， 、 、 和 是数量最多的类群。所获得的数据将有助于研究大赫鲁斯洛梅尼湖微生物群落的多样性和生态作用，并深入了解亚北极湖泊中的生物地球化学过程。原始测序数据可从NCBI序列读取存档（SRA）数据库中获取，生物项目编号为PRJNA503531。
