Pacific Antarctic Cirumpolar Current strength reconstrucion

The data contain the age model data for IODP Expedition 383 Sites U1540 and U1541. The age model of Site U1540 is on graphical correlation (tuning) to IODP Site U1541. Opal content data and opal/CaCO3 ratios are represented for IODP Expedition 383 Sites and POLARSTERN Cruise PS75 sediment cores. The...

Description
Summary:The data contain the age model data for IODP Expedition 383 Sites U1540 and U1541. The age model of Site U1540 is on graphical correlation (tuning) to IODP Site U1541. Opal content data and opal/CaCO3 ratios are represented for IODP Expedition 383 Sites and POLARSTERN Cruise PS75 sediment cores. The data contain the ACC strength record at IODP Site U1540 and Site U1541 and several PS75 sediment cores. The absolute ACC strength record was calculated from sortable silt data using a formula from the Scotia Sea by McCave et al. (2017). The sortable silt record was calculated from ln(Zr/Rb) using a regional calibration from discrete grain-size measurement. The ln(Zr(/Rb record was interpolated to 0.5 kyr and 9-point adjacent averaged.
