High resolution 10Be and 230Th stratigraphy of late Quaternary sediments from the Fram Strait (Core 23235)

Abstract

We obtained a high resolution stratigraphy of sediment Core 23235 (Fram Strait) from the measurement of the concentration of 10Be and 230Th in depth profiles. The average sedimentation rate is approximately 3cm/kyr. On a length of 806cm the Core 23235 covers a time span of approximately 270kyr. The profiles of the concentration of 10Be and 230Th have maxima during interglacials and minima during glacial periods. -from Authors
