Abstract:

Downcore measurements of iceberg-rafted debris (IBRD) flux and biogenic silica concentrations in kasten core IN2017_V01-A042-KC14 from the continental slope of central Wilkes Land, East Antarctica. The IBRD flux was calculated by multiplying the coarse sand fraction by the linear sedimentation rate and the dry bulk density at each depth interval along the core. All of these values are shown. The biogenic silica concentration is shown as a percentage.
