The ProteOMZ Expedition: Investigating Life Without Oxygen in the Pacific Ocean

Untargeted proteomics from a 5,000 km+ transect across the central Pacific Ocean from Hawaii to Tahiti. The expedition crossed multiple biogeochemical provinces, inlcuding the oligotrophic North Pacific Subtropical Gyre, the extremety of the Eastern Tropical North Pacific Oxygen Deficient Zone, and the relatively productive equatorial region associated with upwelling. This dataset focuses on the microbial fraction (0.2-3.0 micrometer filter size) and the microbial community dynamics across these biogeochemical provinces, from the surface oceance to the mesopelagic (1,250 m depth maximum).

本数据集源自跨夏威夷至塔希提岛的中太平洋5000公里以上断面的非靶向蛋白质组学（Untargeted proteomics）研究。本次科考航次跨越多个生物地球化学省（biogeochemical provinces），涵盖寡营养型北太平洋副热带环流区、东热带北太平洋缺氧区（Oxygen Deficient Zone）的极端区域，以及与上升流相关的生产力相对较高的赤道海域。本数据集聚焦于0.2-3.0微米滤膜截留的微生物组分，以及上述生物地球化学省范围内从表层海洋至最大深度1250米的中层带（mesopelagic）海域的微生物群落动态。
