Antarctic relative palaeointensity stack (ANT-1600)

Relative palaeointensity (RPI) stack calculated by interpolating nine published RPI records with IODP Site 379-U1533, and 90% confidence interval of resulting stack. Site IODP Site 379-U1533 RPI calculated by normalising natural remanent magnetisation (NRM) by anhysteretic remanent magnetisation (ARM) (NRM/ARM) for the alternating field (AF) demagnetisation range 20-55 mT. Each record in the stack was interpolated and normalised by their mean age increment and mean value respectively, before bootstrapping each record centred at each 1-kyr time step with a 1-ka overlapping window. RPI records used in the stack are located along the Antarctic Peninsula, the Wilkes Land Margin, and in the Ross Sea, with IODP Site 379-U1533 being the only site located in the Amundsen Sea.
