Overview

Measures organic carbon burial and sediment accumulation in fjords of South Georgia, indicating key environmental implications.

Key Points

  • To quantify organic carbon burial rates and sediment accumulation in the fjords of South Georgia, and understand their role in the carbon cycle.
  • Collected 10 sediment cores from various fjords in South Georgia.
  • Measured sediment accumulation rates using 210 Pb dating.
  • Analyzed total organic carbon content and sediment properties.
  • Sediment accumulation rates ranged from 2.1 to 14.9 mm/yr.
  • Total organic carbon varied from 0.28% to 2.1%.
  • Modern organic carbon burial rates reached 64.6 gOC/m2/yr, suggesting high efficiency in carbon trapping.
