Distribution of foraminifera from South Shetland Islands (Antarctic): Ecology and taphonomy
The aim of this study was to analyze the distribution of foraminifera of surface sediments from South Shetland Islands (62 S 58 W) in relation to physical parameters. Three sites were analyzed: 1) North of South Shetland Island; 2) Deception Island, and 3) Potter Cove. We have identified 21 species,...

The aim of this study was to analyze the distribution of foraminifera of surface sediments from South Shetland Islands (62 S 58 W) in relation to physical parameters.
