THE COMPOSITION AND DISTRIBUTION OF THE PARTICULATE MATTER IN THE STRAIT OF MAGELLAN (CHILE) DURING THE 1991 AND 1995 ITALIAN CAMPAIGNS
During 1991 and 1995, the Italian National Program for Antarctic Research carried out two oceanographic campaigns in the framework of the International (Strait of) Magellan Project. In this paper, we describe the distribution, biochemical composition, and mineralogical characteristics of particulate...

During 1991 and 1995, the Italian National Program for Antarctic Research carried out two oceanographic campaigns in the framework of the International (Strait of) Magellan Project. In this paper, we describe the distribution, biochemical composition, and mineralogical characteristics of particulate matter and the characteristics of the water masses deWning microbasins in the Strait of Magellan. The data analyses highlighted diVerences in quality and quantity of the suspended matter and its organic component in the basins that make up the Strait and the PaciWc Ocean. The westernmost basin is subject to an eastward Xow from the PaciWc Ocean, and continental runoV in the surface layers, which are consequently rich in organic matter with a high C:N ratio.
