Research interests

Current research spans seamount ecology , fisheries , ocean acidificationaquaculture and conservation. I'm also working on Marine Protected Area design using satellite vessel monitoring for fisheries management. My main fieldwork sites are currently at volcanic CO2 vents in the Mediterranean, and coral reefs in the Arctic, the NE Atlantic and off Papua New Guinea.

Recent consultancy work includes a Marine Stewardship Council assessment of the US scallop fishery, an assessment of ship biofouling in African waters for Sach Solicitors Ltd, assessments of the effects of capital dredging in UK waters for Royal Haskoning, assessments of Natura 2000 sites and Marine Conservation Zones for DEFRA and biodiversity reports for OSPAR.  I also conduct commercial diving surveys (e.g. for Chichester Harbour Conservancy, Falmouth Harbour Commissioner,  Natural England, Scottish Environmental Protection Agency, Scottish Natural Heritage) and underwater filming (e.g. for the BBC, CBC (Canada) and ITV).

Ocean acidification tour featuring UK research released by Google

For the first time the story of ocean acidification can now be viewed on a special tour created by Google using Google Earth. Narrated by Dan Laffoley (International Union for Conservation of Nature, IUCN) the video takes the viewer around the planet to understand what ocean acidification is, see some of the latest research into it and hear about how the consequences of ocean acidification are already being felt by the multimillion dollar shellfish industry in the USA. Experts feature in the video in order to further explain ocean acidification, including Marine Ecologist Prof. Jason Hall Spencer (Plymouth University).
