Abundance of calcareous nannofossils in sediments of the Fram Strait, supplement to: Gard, Gunilla (1987): Late Quaternary calcareous nannofossil biostratigraphy and sedimentation patterns: Fram Strait, Arctica. Paleoceanography, 2(5), 519-529
Sediment cores from the Fram Strait are dated by means of calcareous nannofossil biostratigraphy and are shown to represent, at the most, the last 300 kyr (oxygen isotope stages 1-8). Differences in sedimentation rates are mainly controlled by the bottom topography and the intensity of ice-rafted de...

Summary: | Sediment cores from the Fram Strait are dated by means of calcareous nannofossil biostratigraphy and are shown to represent, at the most, the last 300 kyr (oxygen isotope stages 1-8). Differences in sedimentation rates are mainly controlled by the bottom topography and the intensity of ice-rafted deposition. Sedimentation rates are normally in the order of a few centimeters per kiloyear in the central Fram Strait but increase to over 10 cm/kyr in cores located on the continental slope. The highest sediment accumulation rates occurred on the shelf (several tens of centimeters per kiloyear). |
