The fine temporal structure of the geomagnetic field for the past 30 kyr manifests itself in the development of geomagnetic field excursions (sharp geomagnefic pole displacements in latitude and longitude) and in slow variations in the geomagnetic field elements. An analysis of the paleomagnetic characteristics of the Barents bottom sediments shows the Etrussia-Sterno (2300-3000 years ago) and Solovki (4500-7500 years ago) geomagnetic field excursions, the Gothenburg, excursion at the Holocene-Pleistocene boundary (12-13 kyr ago) marking the end of the last glaciation, and the Mono excursion (26-28 kyr ago). A significant increase in the magnetic susceptibility at the Holocene-Pleistocene boundary, observed in eight Barents columns, reflects climate changes during this period. The cyclic component of the variation in the geomagnetic field inclination with a period of about 15 kyr has been revealed.
