We report the intercalibration of paleomagnetic secular variation (PSV) and expanded postglacial sediment cores from geographically proximal, but sedimentologically contrasting settings. The objective is to improve relative what can be achieved with either method alone. Core MD99-2269 was taken from north Iceland shelf. Core MD99-2322 was collected from the Kangerlussuaq Trough margin. Both cores are well dated, with 27 and 20 accelerator mass spectrometry 2322, respectively. Paleomagnetic measurements made on u channel samples magnetization. The temporal similarities of paleomagnetic inclination and shown using each core’s independent calibrated radiocarbon age model. that the relative correlation between the two cores could be further improved. points initially based on calibrated ¹⁴C dates are either adjusted or added to Radiocarbon dates from both cores are then combined on a common depth scale correlation. Support for the correlation comes from the consistent interweaving of Saksunarvatn tephra, and the improved correlation of paleoceanographic proxy results demonstrate that PSV correlation used in conjunction with ¹⁴C dates can also regional chronologies by allowing dates from various stratigraphic sequences higher dating density, age-to-depth model.
