Numbering approximately 10000 species, Foraminifera represent the main various crew of shelled microorganisms within the ocean. also they are probably the most worthy instruments for environmental overview and tracking courses. This advisor via Jean-Pierre Debenay presents an outline of the environmental stipulations round New Caledonia, an available creation to Foraminifera, and a precis of the examine that has been performed from the island kingdom. It additionally describes a couple of thousand species of Foraminifera accumulated round New Caledonia, accompanying every one access with SEM micrographs and notes on its distribution. geared up into teams to make it effortless to spot every one species, will probably be a realistic reference.

The distribution of silt and clay is consistent with the sediment transport direction deduced from the distribution of O. bartshi, and the combination of both sets of information allows a better comprehension of sedimentary dynamic in front of the bay (fig. 40 right). This approach should be of interest owing to the Goro Nickel Mining Project that is developing in the area and will require an extensive environmental assessment.

It contributes to serious organic and chemical pollution of water and bottom sediment in the surrounding environment, but also leads to self-pollution problems in pond production. Semi-intensive shrimp farming is widely distributed along the west coast of New Caledonia Main Island (Grande Terre). Seawater pumped from the nearby ocean filled the ponds at the beginning of the growth cycle. Its daily renewal varies with increasing shrimp biomass, from 0% to 30% per day, keeping salinity between 32‰ and 39‰ and supplying the ponds with smaller, mostly juvenile, foraminifera.
