Research | Current

Seismic studies of near-seafloor hydrocarbon systems, with a focus on gas hydrates, shallow gas, and hydrocarbon seepage, form the main focus of my research.  These systems play significant roles in the global carbon cycle, have an effect on seafloor stability, and also, constitute unconventional natural-gas resources.   Tools for these studies include in particular active-source reflection (2-D and 3-D) and ocean bottom seismic data.  Currently active research projects include the following:
1.    The fate of gas hydrate systems through glacial-interglacial cycles on the Chatham Rise:  Seafloor depressions, commonly termed pockmarks, cover vast areas of the Chatham Rise.  We hypothesize that these pockmarks were formed by rapid release of gas from hydrates in response to depressurization from sealevel lowering.
2.    Gas hydrates as an energy resource: New Zealand has vast quantities of gas hydrates in a favourable geologic setting.  We analyse gas hydrate deposits with a focus on reservoir geophysics and production modelling as part of the GNS-Science-led MBIE-funded programme “Harnessing New Zealand’s Gas Hydrate Resources”
3.    The effect of gas hydrates on seafloor stability: Dissociation (“melting”) of ice-like gas hydrate to gas and water has long been implicated in submarine landslides.  In collaboration with NIWA, GNS Science, the Universities of Kiel, Bremen, and Jena in Germany, as well as Oregon State University, we are studying potential mechanisms that link gas hydrate directly with creeping submarine landslides.
4.    Imaging of plumbing systems beneath hydrocarbon seeps:  Hydrocarbon seeps are key locations for carbon transfer from sediments into the ocean.  We are analysing seismic data acquired in 2011 to investigate migration of gas to gas-vent sites as well as formation of gas hydrates and carbonates on seep sites on the Hikurangi Margin east of the North Island.
