This thesis explores the use of U-Th series isotopes as tracers to study ocean mixing and chemical inputs to the open ocean from atmospheric dust, rivers, continental shelves and ocean sediments.
The use of Th isotopes as an improved tracer of dust input has been tested by measuring 232Th and 230Th concentrations of upper-ocean seawater at six stations along a meridional Atlantic section that spans the Saharan dust ... [truncated at 450 characters in length]

|Abstract||In this thesis I use a multi-disciplinary approach to investigate two areas of active mountain-building within the Alpine-Himalayan belt: the Altai range in western Mongolia, and the Zagros mountains in southern Iran. I begin by studying a clustered earthquake sequence that struck a previously unrecognised fault zone in the NW Altai mountains in 2003. By combining seismology and field observations with satellite radar interferometry (InSAR), I at ... [truncated at 450 characters in length]|
