Abstract

Makassar strait is the very unique waters, the bottom topography was steep and complex, the waters masswas also exceptional since Indonesian through flow carried flavor water from Pacific warm pool to the area.To describe the exceptional of Makassar Strait hydrological characteristics through recent foraminiferalcommunity structure as a proxy, Oceanographical Expedition in Makassar Strait was conducted in October2004. Research Vessel of Baruna Jaya VII was used to carry out the research activities. Sediment layers arean essential tool on recording hydrological information in such period of time, and each certain layerpreserved certain information as a bench mark data at a time period. The result shows that there are 5genera of planktonic foraminifera which generated a bulk in sediment surface. Deep chlorophyll maximum inoceanic region of Makassar Strait was prominent factor generated living planktonic foraminifera in researchlocation. Benthic community was formed by 164 species from 78 genera. Water depth was affected to benthicforaminiferal diversity, distribution and species diversity, which reveal that water depth was limiting factorto benthic foraminiferal assemblage. Uvigerinid was the important taxa which make up 46 to 57 % of thebenthic specimen, particularly in river input yield adjacent area. Uvigerina asperula may considered as anindicator of OMZ (Oxygen minimum zone) in Makassar Strait.

Abstract

The oceanographic research in Nangroe Aceh Darussalam waters post-tsunami was conducted on September 2006. Foraminifera which easily found as element of marine sediment was used as a tool to understand the trace effect of tsunami to marine sediment on the research area. Foraminifera is a single cell organism which has hard cover (test) as a primitive skeleton, that would remain in sediment for a long periods. Samples were carried out from west, north and east part of Nangroe Aceh Darussalam (NAD) Province waters using box-corer. The result showed there have been a mass of energy that force the sediment sliding and triggered the mixture of shallow and deep species of foraminifera in research area, particularly in western part of the waters.
