Position in project: Project researcher

Dr Ivy-Ochs will co-lead, along with Dr Lukas, discussion and evaluation of dated sites, with particular attention to two main issues. Firstly, the sampling ‘errors’ which often occur when dating is attempted on a glacier deposit. For example, the measured date of a moraine, while precise, may be inaccurate due to the duration of moraine construction, stabilization, or reworking. Thus the first task of the Geochronology component is to evaluate whether or not the published ages (based on sample details, moraine morphology, age distributions etc. on each landform reflect a ‘good date’ for that landform.

Research interests related to the project’s scope:

Her research is focused on the use of the cosmogenic nuclides 10Be, 26Al and 36Cl to glean fundamental information about the timing and rates of geomorphological processes and how such processes may have been affected by past variations in climate. In the Alps her interest is in the dating of landscape changing events, primarily glacier advances as recorded by moraines (especially LGM, Lateglacial and Holocene); and large landslides.
