| boxcore | --- | Chemistry Biology Geology | Porewater oxygen microprofiles of abyssal sediment cores from the Samoa Basin (This data release contains porewater oxygen microprofiling data from abyssal sediment cores collected from the Samoa Basin in the South Pacific Ocean within the American Samoa Exclusive Economic Zone. Sediment cores were collected from 35 locations using a box core that was subsampled with push cores. Push cores were immediately transferred to a cold laboratory van, and oxygen was measured using Unisense microsensors inserted through pre-drilled holes in the core liner, spaced at 1 centimeter intervals. These measurements were completed within 3 hours of boxcore recovery. These data were collected shipboard in 2026 on expedition 2026-604-FA.) |
