Profile

Profile

Principal Investigator in Benthic Ecology

My background is in benthic ecology and over the course of my career I have been lucky enough to carry out research in a wide range of marine environments including Scottish sea lochs, Caribbean coral reefs and the deep north Atlantic, Arctic and tropical Pacific oceans. My current interests include the effects of waste disposal and climate change on deep-sea ecosystems and the ecology and conservation of rare benthic communities in Scottish waters. 

At SAMS I am a member of the ...

Research projects

  • Impacts of Deep-Sea Tailings Placement in Papua New Guinea – Over the past years I have been part of a multidisciplinary team from SAMS carrying out the first detailed study of the impacts of mine tailings deposition on the deep-sea bed, carried out at three disposal sites around the coast of Papua New Guinea. I lead the benthic biology component of the project, involving seabed photography and replicated quantitative sampling of meio- and macrofauna.
  • Ecology and conservation of serpulid reefs in Scottish sea lochs: Reefs constructed by the tubeworm Serpula vermicularis are currently found in only two sea lochs in western Scotland and are considered of high conservation importance. My research has involved video monitoring of worm behaviour and use of the reefs by other organisms, and in situ measurements of tube growth and degradation rates. By broadening our understanding of the dynamics and ecological role of serpulid reefs these data will contribute to more effective management of these rare features.

Review and consultancy

I am regularly contracted to write literature reviews and I have also carried out a large number of externally-commissioned research contracts at SAMS. Many of these have been concerned with survey and data analysis for marine biotopes of conservation importance, ranging from the coastal zone to the deep sea west of Scotland.

Recent examples include:

  • Strategic Environmental Assessment (2006-07) – Two contracts to analyse seabed photographs and video footage from the deep seamounts and banks of the northern Rockall Trough (SEA Area 7), including areas which have potential for designation as offshore Marine Protected Areas (MPAs). The work was funded by DTI and Geotek, and carried out in collaboration with Dr Bhavani Narayanaswamy (SAMS), Dr Murray Roberts (Heriot-Watt University, then at SAMS) and Drs Kerry Howell and Jaime Davies (University of Plymouth).
  • Recovering Scotland’s Marine Environment (2009) – A literature review of human impacts on Scottish marine ecosystems and the potential for recovery, commissioned by Scottish Environment LINK, and carried out in collaboration with Dr Thom Nickell (SAMS).
  • Analysis of sensitivity of Priority Marine Features (2010) – I have recently been an invited participant in a two-day workshop held at Natural England, Peterborough, organized to compile expert assessments of sensitivity of selected marine species and biotopes to a range of human impacts. These assessments will be used to guide selection and management of Priority Marine Features across the network of Marine Protected Areas planned for the UK.
