Research interests

My research interests are focused on the use of the novel non-invasive Eddy Correlation technique. This is a truly in situ method for quantifying benthic oxygen exchange as a measure of carbon turnover in marine sediments. This technique has applications in environments where current methods for quantifying oxygen exchange cannot be used, such as solid substrate locations or even vertical undersea cliffs and walls. There is great development potential with this instrumentation and in the future we hope to be able to quantify hydrogen sulphide fluxes as well as other important nutrients.

project

Benthic oxygen exchange across soft and hard bottoms using the new non-invasive Eddy Correlation technique: case studies from the tropics to the Arctic: Project description and objectives

My project is primarily based around using the novel in situ Eddy Correlation technique as a new way to quantify benthic oxygen exchange across a wide range of marine sediment types, from soft highly active sediments to hard sediments with biofilm layers of bacteria or algae.

The objectives of the project are to quantify oxygen fluxes over different marine sediment types alongside benthic chamber measurements e.g. Arctic sediments, equatorial sea mounts, permeable coarse sediments on the Great Barrier Reef, oligotrophic sediments and maerl beds in Scottish waters. A seasonal study of benthic primary production in a bay on the Scottish west coast will also be carried out using the Eddy Correlation technique.
