Granulometry of two sediment cores from Maxwell Bay, South Shetland Islands, West Antarctica ...
The climate evolution of the South Shetland Islands during the last c. 2000 years is inferred from the multiproxy analyses of a long (928 cm) sediment core retrieved from Maxwell Bay off King George Island. The vertical sediment flux at the core location is controlled by summer melting processes tha...
