Extended Data Fig. 1: Indicators for bulk sediment composition of PS58/270-5.
From: South Pacific carbon uptake controlled by West Antarctic Ice Sheet dynamics
(a) Total carbon content. (b) Calibrated calcium (Ca) concentrations (see also Extended Data Fig. 6e). (c) Opal content and the natural logarithm (LN) of XRF scanner silicon/titanium (Si/Ti). (d) Calibrated iron (Fe) concentrations in red (see also Extended Data Fig. 6d) and terrigenous content calculated by subtraction of total carbon (%) and opal (%) from 100 %. MIS = Marine Isotope Stage. See Methods for more details.
