In situ incubations with the Gothenburg benthic chamber landers: Applications and quality control

In situ incubations of sediment with overlying water provide valuable and consistent information about benthic fluxes processes at the sediment-water interface. this paper, we describe our experiences a variety applications from last 14 years 308 deployments Gothenburg chamber lander systems. We give examples how use sensor measurements for leakage control, in volume determination, control syringe sampling times, resuspension stirring quality. present incubation data oxygen, dissolved inorganic carbon, nutrients, metals gases made landers, as well manipulative injection experiments to study nitrogen cycling (injections 15N nitrate), phosphate retention marl suspension) targeted resuspension. Our main goal is demonstrate possibilities that systems offer measure solute Based on experience, recommend procedures be used order obtain high quality landers.
