"In the southwestern part of the lagoon of New Caledonia (South Pacific Ocean), a plankton sampling program was conducted from Feb. 1978 to April 1979. During 11 cruises, 5 stations in the open sea and various bays were sampled at approximately monthly intervals. A transect of 3 stations (mid-lagoon, near-reef and barrier-reef channel), visted every 2 wk, completed the sampling program. The 52 most abundant copepod species were analyzed for seasonal and regional variations. Cruise and transect data, dealt with separately, were analyzed in a variety of ways. Correspondence analyses (reciprocal averaging) of qualitative and quantitative copepod counts were made. Species partition was achieved by 2 successive methods: non-hierarchical, followed by hierarchical classification. Between-species distance was computed from their coordinates on the factorial axis. Species clusters obtained were plotted in the factorial planes to assess ecological preferences. The main ecological factors appear to be spatial patterns, seasonal temperature cycle, and changes in wind force and direction. Different populations inhabit the open sea, near-reef, mid-lagoon, shallow and deep-bay waters. Acartia australis outnumbers all other species in the reef vicinity. A. amboinensis is the most abundant in the deep, fjord-like bay. Canthocalanus pauper, Paracalanus parvus, Bestiola sp., Centropages orsinii and A. bispinosa are characteristic of shallow bays. Seasonal barycenters appear close to some station barycenters: summer close to mid-lagoon, winter close to open sea, and spring close to near-reef barycenters, respectively. This may be explained by the seasonal dynamics of the lagoon water. Variations of plankton populations and biomass in the lagoon seem to be governed by the direction of water flow across the reef channels. Enrichment factors are terrestrial sediment wash-out after rainfall and, probably, trade wind-induced upwelling." . "Binet (1984)" . . "Binet (1984)" . . "1984"^^ .
