Monothalamous foraminifera from West Spitsbergen fjords, Svalbard: a brief overview
During the 2004 summer season, 14 sediment samples were collected in Kongs− fjorden and Isfjorden, West Spitsbergen, from 6 down to 345 m water−depth (mwd). The samples yielded abundant assemblage of monothalamous foraminifera, belonging to almost 40 morphotypes. Our qualitative (>125 μm) and quantitative data (125–500 μm) allowed to distinguish three water−depth related assemblages in both Kon...
متن کاملLarger benthic foraminifera from the Middle Eocene
Larger benthic foraminifera (LBF) are common and diverse throughout the Paleogene sediments of southern Tanzania, but have previously been little studied. A recent programme of onshore drilling known as the Tanzania Drilling Project has recovered large proportion of this succession for palaeoclimatic and palaeontological study. The sediment is largely a hemipelagic clay with secondary gravity s...
متن کاملBa incorporation in benthic foraminifera
Barium (Ba) incorporated in the calcite of many foraminiferal species is proportional to the concentration of Ba in seawater. Since the open ocean concentration of Ba closely follows seawater alkalinity, foraminiferal Ba /Ca can be used to reconstruct the latter. Alternatively, Ba /Ca from foraminiferal shells can also be used to reconstruct salinity in coastal settings in which seawater Ba con...
متن کاملO/O measurements on benthic foraminifera
[1] We explore the applicability of paired Mg/Ca and O/O measurements on benthic foraminifera from Southern Ocean site 747 to paleoceanographic reconstructions on pre-Pleistocene timescales. We focus on the late Oligocene through Pleistocene (27–0 Ma) history of paleotemperatures and the evolution of the dO values of seawater (dOsw) at a temporal resolution of 100–200 kyr. Absolute paleotempera...
