Dansgaard-Oeschger cycles: Interactions between ocean and sea ice intrinsic to the Nordic seas
(American Geophysical UnionWiley, 2013-09)
Dansgaard-Oeschger (D-O) cycles are the most dramatic, frequent, and wide-reaching abrupt climate changes in the geologic record. On Greenland, D-O cycles are characterized by an abrupt warming of 10 ± 5°C from a cold ...
Experimental investigation of deformation mechanisms during shear-enhanced compaction in poorly lithified sandstone and sand
Shear-enhanced compaction in shallow sandstone reservoirs has been investigated in laboratory experiments using high-pressure triaxial testing of poorly lithified sandstone and sand. We have studied the deformation ...
Geometries of doleritic intrusions in central Spitsbergen, Svalbard: an integrated study of an onshore-offshore magmatic province with implications for CO2 sequestration
(Geological Society of Norway, 2013)
Igneous intrusions emplaced during the Early Cretaceous are well exposed in central Spitsbergen within the Permian–Jurassic sedimentary succession. The doleritic intrusions are collectively classified as the Diabasodden ...
Increased ventilation of Antarctic deep water during the warm mid-Pliocene
(Nature Publishing Group, 2013-02-19)
The mid-Pliocene warm period is a recent warm geological period that shares similarities with predictions of future climate. It is generally held the mid-Pliocene Atlantic Meridional Overturning Circulation must have been ...
Northern hemisphere glaciation during the globally warm early late Pliocene
The early Late Pliocene (3.6 to ,3.0 million years ago) is the last extended interval in Earth’s history when atmospheric CO2 concentrations were comparable to today’s and global climate was warmer. Yet a severe global ...
Refining benthic foraminiferal Mg/Ca-temperature calibrations using core-tops from the western tropical Atlantic: Implication for paleotemperature estimation
(WileyAmerican Geophysical UnionGeochemical Society, 2013-04)
Benthic foraminiferal Mg/Ca has been shown to have great potential as a proxy for reconstructing deep water temperatures. However, the exact relationship between Mg uptake in benthic foraminifera and temperature is still ...
