Burdett, 2013 ii Dedication In loving memory of my Grandads; you may not get to see this in person, but I hope it makes you proud nonetheless. John Hewitson Burdett 1917 – 2012 and Denis McCarthy 1923 - 1998 Heidi L. Burdett March 2013 iii Abstract Dimethylsulphoniopropionate (DMSP) is a dimethylated sulphur compound that appears to be produced by most marine algae and is a major component of the marine sulphur cycle. The majority of research to date has focused on the production of DMSP and its major breakdown product, the climatically important gas dimethylsulphide (DMS) (collectively DMS/P), by phytoplankton in the open ocean.
