Coastal Processes within a Coral Reef Lagoon System: Erakor Lagoon, Efate Island, Vanuatu

Detrital pathways in a coral reef lagoon

Coral reef lagoons are generally regarded as zones of net heterotrophy reliant on organic detritus generated in more productive parts of the reef system, such as the seaward reef flat. The abundance and biomass of sediment infauna were measured seasonally for one year (1986) within the lagoon of Davies Reef, central Great Barrier Reef, to test the hypothesis that macrofaunal biomass and product...

Episodic circulation and exchange in a wave-driven coral reef and lagoon system

We examined the role of wave-driven circulation relative to wind and buoyancy forcing in a coral reef–lagoon system. Circulation measurements in Paopao Bay, Moorea, French Polynesia, during austral summer show the importance of waves in driving flows over the reef crest, through the lagoon, and out the reef pass. Tides were comparatively weak, due to proximity to amphidromic points, and exhibit...

Annual sediment primary production and respiration in a large coral reef lagoon (SW New Caledonia)

Sediment photosynthetic production and community respiration were investigated for 1 yr in the south-west lagoon of New Caledonia (surface area: 2000 km'; mean depth: 21 m). Metabolic fluxes were measuredbat the water-sediment interface using benthic enclosures, at 60 sampling stations randomly distributed in space and time. Mean gross primary production (Pg) was 12.06 mol C m-' yr-l. Mean resp...

The hyperbenthic plankton community: composition, distribution, and abundance in a coral reef lagoon

Seasonal and diel variations in community structure and abundance of the lagoon hyperbenthic community were examined at Davies Reef, Great Barrier Reef. The lagoon floor community differed from that in the overlying water, it was faunistically more uniform, and it was assembled into statistically distinct seasonal and diel groupings. The lagoon floor community was characterized by reef-associat...
