Bathymetric Control on Borchgrevink and Roi Baudouin Ice Shelves in East Antarctica
Eisermann, Hannes; Eagles, Graeme; Ruppel, Antonia Stefanie; Läufer, Andreas; Jokat, Wilfried (Journal of Geophysical Research: Earth Surface, 2021-10-07)The stability of ice shelves and drainage of ice sheets they buttress is largely determined by melting at their atmospheric and oceanic interfaces. Subglacial bathymetry can impact ice shelf stability because it influences ... -
Bathymetry Beneath Ice Shelves of Western Dronning Maud Land, East Antarctica, and Implications on Ice Shelf Stability
Eisermann, Hannes; Eagles, Graeme; Ruppel, Antonia; Smith, Emma Clare; Jokat, Wilfried (Geophysical Research Letters, 2020-06-13)Antarctica's ice shelves play a key role in stabilizing the ice streams that feed them. Since basal melting largely depends on ice‐ocean interactions, it is vital to attain consistent bathymetry models to estimate water ... -
Crustal variability along the rifted/sheared East African margin: a review
The East African margin between the Somali Basin in the north and the Natal Basin in the south formed as a result of the Jurassic/Cretaceous dispersal of Gondwana. While the initial movements between East and West Gondwana ... -
Deposition History and Paleo-Current Activity on the Southeastern Lomonosov Ridge and its Eurasian Flank Based on Seismic Data
A regional seismic survey on the southeastern Lomonosov Ridge (LR) and adjacent basins provides constraints on the coupled evolution of ocean circulations, depositional regime, and tectonic processes. First, Mesozoic strata ... -
Preserved landscapes underneath the Antarctic Ice Sheet reveal the geomorphological history of Jutulstraumen Basin
Franke, Steven; Eisermann, Hannes; Jokat, Wilfried; Eagles, Graeme; Asseng, Jölund; Miller, Heinrich; Steinhage, Daniel; Helm, Veit; Eisen, Olaf; Jansen, Daniela (Earth Surface Processes and Landforms, 2021-08-28)The landscape of Antarctica, hidden beneath kilometre‐thick ice in most places, has been shaped by the interactions between tectonic and erosional processes. The flow dynamics of the thick ice cover deepened pre‐formed ... -
Simulated Thermohaline Fingerprints in Response to Different Greenland-Scotland Ridge and Fram Strait Subsidence Histories
Hossain, Akil; Knorr, Gregor; Lohmann, Gerrit; Stärz, Michael; Jokat, Wilfried (Paleoceanography and Paleoclimatology, 2020)Changes in ocean gateway configuration can induce basin-scale rearrangements in ocean current characteristics. However, there is large uncertainty in the relative timing of the Oligocene/Miocene subsidence histories of the ... -
The Impact of Different Atmospheric CO2 Concentrations on Large Scale Miocene Temperature Signatures
Hossain, Akil; Knorr, Gregor; Jokat, Wilfried; Lohmann, Gerrit; Hochmuth, Katharina; Gierz, Paul; Gohl, Karsten; Stepanek, Christian (Paleoceanography and Paleoclimatology, 2023-02-07)Based on inferences from proxy records the Miocene (23.03–5.33 Ma) was a time of amplified polar warmth compared to today. However, it remains a challenge to simulate a warm Miocene climate and pronounced polar warmth at ...
