In situ tracer studies of solute transport across the sedimentwater interface at the Bermuda Time Series site

摘要: Abstract In situ tracer experiments have been utilized to assess the rates of transport solutes across sediment-water interface in deep sea at Bermuda Time Series site. The site lies some 83 km southeast Bermuda, an environment considered be representative oligotrophic gyre. Transport has evaluated on basis release NaBr into benthic chambers and determinations Br losses from as well − profiles inventories sediments recovered chambers. provide no evidence excess that expected for diffusion alone. sensitivity our analysis variations rate places a limit non-diffusive ≤25% diffusive transport.
