Research

PhD Research Student

        My research involves analysing video-imaging data (collected on Cruise JC24, summer 2008) and
        using it alongside sidescan sonar and M2000 high resolution bathymetric imagery to determine the
        detailed structure and the morphological, spatial and temporal variations between the different
        volcanic units in a typical Axial Volcanic Ridge (AVR) on the Mid-Atlantic Ridge at 45°N. I am
        in the process of integrating this morphological and statistical work with strontium isotope
        geochemistry (which I have carried out) and geochemical and uranium series dating analyses
        (done at other institutions). I aim to build up a comprehensive volcanological model of an AVR
        and in doing so address a number of current hypotheses concerning AVR growth, structure and
        development through time.
        So far this project has involved:
             • Identification and detailed description of different volcanic units and lava morphologies
                  from high resolution bathymetry and sidescan sonar imagery
             • Statistical analyses of distribution, cluster and alignment of volcanic cones
             • High resolution mapping of the AVR
             • Use of GIS technologies (including ArGIS and Adelie)
             • Creating interactive 3D flythroughs of the seafloor
             • Strontium isotope analyses of zoned plagioclases in samples
             • Integration of various datasets to produce a model

Monterey Bay Aquarium Research Institute (MBARI)                                 (June-August 2010)
Summer Intern

        As a summer intern at MBARI I designed and conducted a research project to map the extents
        of and constrain the timing of historic eruption on the North Gorda and Juan De Fuca Ridges.
        Mapping was conducted using high resolution bathymetry data collected by the MBARI
        Autonomous Underwater Vehicle (AUV). In order to better constrain eruption extents I also
        analysed bulk geochemical data from samples and Remotely Operated vehicle (ROV) video
        data.
        The project involved:
             • Identification and detailed description of volcanic units and lava morphologies from
                 high resolution bathymetry map of several areas
             • Statistical analyses of eruption and edifice spacing
              •   High resolution mapping of over 17 different lava flows across three mid-ocean
                  ridges


Cruises
Shipboard Scientific Party, R/V Western Flyer (Principle Investigator: David Clague) (August 2010)
Shipboard Scientist, Cruise JC24 to the Taney Seamounts (Eastern Pacific Ocean)

         The cruise aimed to investigate seamount construction and caldera formation on an extinct
spreading ridge. Sampling and video dives were undertaken with the Remotely Operated Vehicle
(ROV) Doc Ricketts to investigate changing magma composition and mapping was carried out to
investigate the relationship of volcanic features and lava morphologies to each other.

              •   Worked as part of a team monitoring the ROV and keeping the cruise log
              •   Using GIS to plan dive routes and sampling strategy on bathymetric maps
              •   Processing samples and cataloguing at the surface
              •   Geological Mapping


Shipboard Scientific Party, RRS James Cook (Principle Investigator: Roger Searle)       (May/June 2008)
Shipboard Scientist, Cruise JC24 to the Mid-Atlantic Ridge (45°N)

          The cruise aimed to test hypothetical models of AVR development and to quantify the flow of
          matter and heat from the mantle to the crust. The cruise gathered Video data and high
          resolution bathymetry of the seafloor as well as a selection of samples (using the ISIS
          Remotely Operated Vehicle) and geophysical data (using TOBI). Onboard I:
              • Worked as part of a team monitoring ISIS, taking photos and recording observations
              • Worked as part of a team monitoring TOBI and plotting navigational data
              • Was responsible for creating relative ages maps based on sediment thickness
              • Assisted Cataloguing samples
              • Was responsible for writing the daily diary on the cruise website (available at
                   www.classroomatsea.net/JC24/index.html)
