Thaumarchaeota archaeon SCGC AC-312_G04 Genome sequencing. Thaumarchaeota archaeon SCGC AC-312_G04

Single-cell genome sequencing to explore relationships between physiological succession, ecotype partitioning, and taxonomic replacement under changing levels of water column O2-deficiency. Samples were taken from an ongoing time-series program monitoring microbial community responses in seasonally anoxic coastal, transition, and open-ocean OMZs (oxygen minimum zones). The focus will be on samples from the northeastern subarctic Pacific Ocean (NESAP), which contains the largest and least-studied permanent OMZ in the global ocean.

本研究采用单细胞基因组测序技术，旨在揭示水体缺氧程度动态变化过程中，微生物生理演替、生态型分化与分类群替代三者间的内在关联。样本取自一项持续推进的时间序列监测计划，该计划针对季节性缺氧的近岸、过渡带及远洋氧最低区（oxygen minimum zones, OMZs）内的微生物群落响应开展监测。本研究的核心样本取自东北亚北极太平洋（northeastern subarctic Pacific Ocean, NESAP），该区域拥有全球海洋中规模最大且研究程度最低的永久性氧最低区。
