MEASUREMENT OF THE EXCHANGE OF FLOATING ORGANIC MATTER AT THE OUTLET OF AMPARU TIDAL LAGOON

Abstract

The floating organic matter exchange between reef and tidal flat is an important factor to keep the nutrients balance of whole water environment.
In this study, characteristics of floating matter exchange between the reef and the tidal lagoon was investigated based on field experiment and survey. It was found that floating matter accumulation along the shore line makes significant impact on the total organic flux from the reef to the lagoon. The floating matter trap which can be set on fast current was innovated. Flood tide and ebb tide transport different kind of floating matter; marine products and mangrove products respectively. Flooding from the river reduces the sea products transportation during flood tide.
