Laboratory experiments and field measurements were conducted to examine the effect of tide on the organic carbon mineralization rate in sediments under aerobic conditions of an intertidal estuary. Core samples of surface sediments were collected from

The drift numerical simulation model of the Seto Inland Sea with 0.5' mesh was constructed to search for problem of marine litter in the sea. The particles assumed to the floating litter were released from 13 rivers in these models and were traced fo

The contribution of benthic microalgal production has been compared both within and outside a coastal eelgrass ( Zostera marina L.) meadow. Carbon and nitrogen stable isotope ratios of suspended particulate organic matter (POM), epiphytic and epilith

Sedimental cores from the Gulf of Thailand were collected by core sampler for examination of δ 13 C and δ 15 N and organic carbon and nitrogen contents. The δ 13 C of surface (0–2 cm) sediments from the whole Gulf gave approximately the same val

Benthic microalgal production has been clarified to be comparable to water column pro- duction in coastal shallow water ecosystems. The present study examined carbon transport pathways from microphytobenthos to predators in a food web of an exposed h

Field surveys of the bottom turbid layer were undertaken from the Changjiang estuary to the mid-continental slope area in the East China Sea to study the bottom turbid layer formation process and ascertain the role of material transport. A dramatic d

The relative importance of benthic and pelagic primary production for demersal fish and some invertebrates in the western Seto Inland Sea of Japan was examined using carbon and nitrogen stable isotope analyses. A few fishes, such as juvenile black ro

The seasonal variations in pollutant loads and water qualities in Hiroshima bay, in order to get basic data for water quality modelling in that bay, were investigated. We have estimated inflow pollutant loads of freshwater, COD and nutrient into Hiro
