Pre-development denudation rates for the Great Barrier Reef catchments derived using Be.

Understanding of the pre-development, baseline denudation rates that deliver sediment to the Great Barrier Reef (GBR) has been elusive. Cosmogenic Be in sediment is a useful integrator of denudation rates and sediment yields averaged over large spatial and temporal scales. This study presents Be data from 71 sites across 11 catchments draining to the GBR: representing 80% of the GBR catchment area and provide background sediment yields for the region.
