Epipelagic mesozooplankton distribution and abundance over the Mascarene Plateau and Basin, south-western Indian Ocean Marine & Ocean Science
Gallienne, C.P.; Conway, D.V.P.; Robinson, J.; Naya, N; Williams, J.S.; Lynch, T.; Meunier, S..
The crescent shaped Mascarene Plateau (southwestern Indian Ocean), some 2200 km in length, forms a partial barrier to the (predominantly westward) flow of the South Equatorial Current. Shallow areas of the Mascarene Plateau effectively form a large shelf sea without an associated coastline. Zooplankton sampling transects were made across the plateau and also the basin to the west, to investigate the role the partial interruption of flow has on zooplankton biomass and community structure over the region. Biomass data from Optical Plankton Counter (OPC) analysis, and variability in community structure from taxonomic analysis, appear to indicate that the obstruction by the plateau causes upwelling, nutrient enrichment and enhanced chlorophyll and secondary...

Regional report « coral reef monitoring » - South West Indian Ocean Region – 2003 Annual Report OceanDocs
Koonjul, M.; Meunier, S.; Moyne-Picard, M.; Bigot, L.; Tara, L.; Jean, M.; Bijoux, J.; Ahamada, S..
The coral reefs of the Indian Ocean are characterized by a high degree of endemic organisms and biodiversity. Over and above their global importance, they are revenue sources for the coastal and insular populations, and play an important role in coastal protection, in an area that is subjected to strong cyclonic activity. Coral reefs are present in the five member states of the IOC. They constitute a federative theme for the region, which justifies the need to develop a “reef monitoring action” through a “regional reef-monitoring network”. It was made clear during recent regional meetings that the reefs are subjected to very strong pressure due to human activities and natural factors (El Niño, massive coral mortality of 1998), and that their conservation...

Status Of Coral Reefs In The South West Indian Ocean Island Node: Comoros, Madagascar, Mauritius, Reunion And Seychelles OceanDocs
Bijoux, J.; Moyne-Picard, M.; Paupiah, N.; Ahamada, S.; Meunier, S.; Maharavo, J.; Bigot, L..
A regional monitoring network of the GCRMN was formed just after the major coral bleaching event in 1998. The goal was to assist the Comoros, Madagascar, Mauritius, Reunion and Seychelles manage their reef resources within the Regional Environment Programme of the Indian Ocean Commission. The Node is now being financed for 3 years by the Global Environment Facility (GEF and World Bank) and the European Union to continue coral reef monitoring to strengthen the capacity of national networks to provide data and advice for resource management. The extent of monitoring has increased from 43 stations in 1999/2000 to more than 70 stations in 2002, with more than 20 stations in Marine Protected Areas (MPAs). The trend on Comoros is for considerable coral...
