Objective | In order to determine the fate of organic particles from the Rhone river once in the Gulf of Lion, we proposed to take measurements of organic matter recylcing in the sediments of the Rhone prodelta, the first place where these particles are deposited. Two techniques were implemented to measure the oxygen demand of the sediment and in situ oxygen profiles. The SOD measurements were done by incubated core samples on board or in the laboratory in chamber kept at a constant temperature (Denis et al., 2001). The oxygen profile measures were taken in situ using an autonomous benthic profiler. Profiles were taken in 0.2 mm steps thanks to polarographic micro-electrodes which provide sufficient resolution to be able to estimate the flux of diffusive oxygen. This falls under the PNEC project, Gulf of Lions worksite. |
