Research interests

  • Marine Environmental Mapping Programme (MAREMAP): Mapping the offshore sea-bed substrate, geomorphology and Quaternary Geology utilising shallow seismic, sidescan sonar, multibeam echosounder and sample data. Development/promotion of new and novel techniques for acoustic data interpretation.
  • Marine habitat mapping working with marine biologists to investigate the relationship between sea-bed substrate and associated biological communities.
  • UK involvement in the Integrated Ocean Drilling Program.

Professional association

  •  2002 : Fellow of the Geological Society of London

Boards and committees

  •  2012 – ongoing : MASTS Deep-Sea Forum

Current projects and collaboration

  • Marine Sea-bed Mapping Initiative focusing on the glacial geomorphology and evolution of the Firth of Forth region, East Scotland.
  • Geological interpretation of the sea-bed sediments, geomorphology and geological evolution of the Explorer and Dangeard canyons of the UK South West Approaches (UK).
  • Studies into the initiation, growth and demise of cold-water coral mini-mounds. A collaborative project (MINIMOUND) led by Prof. Dr. David Van Rooij (Universiteit Gent).
  • Modelling the distribution of vulnerable ecosystems: Ongoing research with Dr Kerry Howell (University of Plymouth, Mapping the Deep Project Video) looking at modelling the distribution of Vulnerable Marine Ecosystems (Annex I of the Habitats Directive) in deep-water areas west of the United Kingdom.
