Research Abstract

High precision O2 controller was developed to measure diffusive O2 uptake on board. O2 profiles at sediment surface taken from off Hachinohe (water depth of 500m, 112uM in bottom watear), 1000m (36uM) and 2000m (70uM) were measured with the O2 controller and O2 microelectrodes. O2 uptake in each core was calculated applying diffusion model, and the rates were 2.7-4.2, 0.6-0.7 and 1.4-1.6mm m-2 d-1, respectively. Carbon dioxide production rates were estimated to 2.1-3.1, 0.5 and 1.1-1.2 mmolC m-2 d-1, respectively to apply Redfield ratio.
