Chris Marsay

Chris is a chemical oceanographer with research interests focusing on trace element biogeochemistry. In particular, he is interested in how trace element distributions in the surface ocean are influenced by atmospheric inputs, and the role that marine particles play in the cycling of trace elements and carbon in the marine environment.

Chris received a PhD in Oceanography from the University of Southampton and is currently a post-doctoral researcher at the University of Georgia Skidaway Institute of Oceanography. He will be joining the GEOTRACES GP15 cruise for the second leg, taking over from Dr Clifton Buck as the scientist responsible for collecting atmospheric aerosols and precipitation samples. These samples are important for helping to quantify the supply of various nutrient and pollutant trace elements to the ocean from atmospheric deposition.

Following the cruise, Chris will be responsible for processing and analyzing the aerosol samples to determine their chemical composition. He will also measure the solubility of different elements within the aerosols, to determine how significant the atmospheric supply is in contributing to dissolved trace element concentrations in the surface ocean.
