Abstract. The analysis of paleomagnetic characteristics of bottom sediments from the northern part of the Barents Sea sampled during the 2023 expedition allowed us to presumably trace the interval with the Gothenburg excursion (13,000-12,000 years ago) and identify a marking layer with anomalous values of paleomagnetic parameters. The anisotropy of magnetic susceptibility data serves as an indicator of the magnetic texture of sediments, which provide information on the hydrodynamics of sedimentation. The complex analysis of magnetic susceptibility curves and grain size distribution traces the wedging of the layer from the deeper part of the section to the Perseus Bank. As a result, the measurements obtained provide additional information not only for stratigraphic dissection and correlation of Upper Quaternary deposits, but also for studying the dynamics of the geomagnetic field and climate. Keywords: bottom sediments, paleomagnetic studies, excursions, magnetic susceptibility, anisotropy, Barents Sea
