Formation and Evolution of Valdivia Bank, Walvis Ridge, South Atlantic Ocean from Geophysical Data and International Ocean Discovery Program Expedition 391 Drilling Results
Valdivia Bank is an oceanic plateau in the South Atlantic, part of the Walvis Ridge hotspot track, that was formed at the Mid-Atlantic Ridge by plume-ridge volcanism during the Late Cretaceous. Oceanic plateaus are shallow rises on the ocean floor that are emplaced by thick accumulations of lava. …

3D Analysis of Fe-Ti Oxides and How They Affect Crystal-Plastic Deformation in Atlantis Bank, Southwest Indian Ridge
… scans of 15 samples from three different Ocean Drilling Program and International Ocean Discovery Program drill holes using the Nikon NIS Advanced Research 3-D visualization program and producing plots and statistics from MATLAB. Results indicate a wide range of textures across a range of …

Ocean circulation and carbon cycle dynamics in the Pacific Southern Ocean during Late Pleistocene interglacials
The Southern Ocean is a key component of the global ocean overturning circulation, enabling water mass exchange between ocean basins, driving Antarctic Bottom Water and Antarctic Intermediate Water formation and providing the major return path of Circumpolar Deep Water (CDW) to the ocean surface. …

Fracture Analysis of the Lower Oceanic Crust, Atlantis Bank, Southwest Indian Ridge
<p>Atlantis Bank (AB) is an oceanic core complex (OCC), formed at the slow-spreading (spreading rate/yr) Southwest Indian Ridge (SWIR)-Atlantis II transform junction. AB is a domal massif composed of lower crustal and upper mantle rocks exhumed along a normal-sense detachment shear zone/fault. OCCs …

High-latitude sedimentation in response to climate variability during the Cenozoic
… (3.3 to 0.7 Ma), and features results from two International Ocean Discovery Program (IODP) Sites U1525 and U1524. Each of these sites is discussed in separate chapters here (Chapters 1 and 2). This interval experienced the change from the warming of the Late Pliocene, known as the …

Basalt Magmatism as a Key to Unlocking Cenozoic Dynamic Topography
… Igneous Province that fringes the North Atlantic Ocean is placed in an Icelandic Plume context. The principal objective of this dissertation is to constrain the spatial and temporal thermal structure of the uppermost mantle in these regions by exploiting thermobarometric and geochemical modelling …
