Dr Mark E. Vardy, Post Doctoral Researcher
Mark Vardy is a post-doctoral researcher, working at the National Oceanography Centre, Southampton. His research interests are primarily focussed toward the development and application of novel, high-resolution marine seismic acquisition and processing methodologies.
These interests have grown out of his recently completed PhD, which was focussed on the acquisiton and processing of decimetre-resolution 3D seismic volumes using the 3D Chirp sub-bottom profiler. Particular attention has focussed on sampling of the 3D wavefield and methods of regularization to accommodate undersampling prior to pre- or post-stack 3D time migration, along with very high-resolution PSDM imaging using the University of Southampton's custom MCS streamer.
These techniques have been applied to a wide range of targets (both natural and anthropogentic; spanning 10s cm to 10s km in scale) and settings. These include: shallow-water engineering targets in several harbours on the south coast of the UK and Holland; submarine landslide in Windermere, UK Lake District, the Bay of Trondheim and Finneidfjord, central Norway; and pyroclastic density current deposits offshore Montserrat. On-going research is focussed on the geomorphological imaging of shallow-water submarine landslide structures, and retreat dynamics of the terrestrial British and Irish Ice Sheet.

Methane Hydrates
Investigating and modelling how ocean warming can affect the stability of methane hydrates in Arctic Ocean sediments, causing hydrates to thaw and the greenhouse gas methane to be released into the surrounding seawater and the atmosphere.
