Dr Andrew Rees is a senior scientist at PML. He has a wide experience within the field of marine nutrient cycling and phytoplankton productivity, initially on extensive field surveys of the estuarine and oceanic distribution of denitrification and nitrous oxide and, more recently, on the pelagic uptake and flux of nitrogen with respect to bacterial and phytoplankton productivity. His published papers relate to expertise in the use of relevant analytical procedures, including stable isotope mass spectrometry, gas chromatography and nutrient autoanalysis.

Andy leads the nutrient cycling group at PML and is manager of the Atlantic Meridional Transect (AMT) programme (2007–present). Current research projects include the impact of ocean acidification on the marine nitrogen cycle, the activity and distribution of nitrogen fixing organisms and the sea-air flux of nitrous oxide and methane in ocean and coastal waters.

Andy has written over 50 peer reviewed research papers.
