(Table T1) Major ion concentrations of interstitial waters from six ODP Leg 201 sites@en

Leg 201 of the Ocean Drilling Program (ODP) focused on understanding subsurface microbial communities and their influence on the chemistry of the surrounding environment (D'Hondt, Jørgensen, Miller, et al., 2003, doi:10.2973/odp.proc.ir.201.2003). During the cruise, sediment cores were collected from four different marine environments of the eastern Pacific Ocean: deep open ocean beneath the moderately productive upwelling regime of the equator (Sites 1225 and 1226), shallow waters of the highly productive Peru shelf (Sites 1227-1229), a deepwater gas-charged zone in the Peru Trench (Site 1230), and a deep open-ocean area under oligotrophic waters (Site 1231). Each of these sites had been drilled previously (during either Deep Sea Drilling Project [DSDP] Leg 34, ODP Leg 112, or ODP Leg 138), although not for detailed microbiological or geochemical investigations. […]大洋钻探计划（Ocean Drilling Program, ODP）第201航次旨在揭示地下微生物群落及其对周边环境化学特征的影响（D'Hondt、Jørgensen、Miller等，2003，doi:10.2973/odp.proc.ir.201.2003）。本航次期间，研究团队从东太平洋四类不同海洋环境中采集了沉积岩芯：分别为赤道中等生产力上升流体系下方的深海开阔洋区（1225、1226站位）、高生产力秘鲁陆架浅水区（1227-1229站位）、秘鲁海沟内的含气深水带（1230站位），以及寡营养水体下方的深海开阔洋区（1231站位）。上述所有站位此前均已完成钻探，分别于深海钻探计划（Deep Sea Drilling Project, DSDP）第34航次、大洋钻探计划第112航次或大洋钻探计划第138航次期间，但彼时并未开展针对性的细致微生物学与地球化学研究。[…]
