Extended Data Fig. 4: Age model results for core PS58/270-5.
From: South Pacific carbon uptake controlled by West Antarctic Ice Sheet dynamics
(a) Age-depth plot based on tie points (Extended Data Fig. 2). (b) Comparison of manual tuning of tie points (see Extended Data Fig. 2) with 230Thxs-derived age constraints for core PS58/270-5 (white dots) after ref. 79. Black line: 1:1 relationship between the two age models (perfect agreement). Note that the part older than ~300 ka BP is not very well-constrained for its 230Thxs content (see Methods for more details).
