Dr Vassilis Kitidis has interests which lie in the biogeochemical cycling of key elements (O, C, N) in the marine environment. Elemental cycles are intimately connected in the Earth system through its living component. I work on processes that operate at the sea-air interface, through the water column and in sediments. Key interests include the photochemical cycling of dissolved organic matter, carbonate chemistry and greenhouse gas cycling and benthic nitrogen cycling.


Ocean Regulation of Climate through Heat and Carbon Sequestration and Transports (ORCHESTRA)

Ocean Regulation of Climate through Heat and Carbon Sequestration and Transports (ORCHESTRA)
