Sea Surfaces

Project

My project focuses on investigating the role of Transparent Exopolymer Particles (TEP) in the Sea Surface Microlayer (SML). TEP is an aggregation of plankton exudates that due to its “sticky” nature functions as the main transport vector for organic carbon, nutrients and trace metals. Using a combination of lab experiments and in situ-experiments, I will be looking at the effects of primary productivity, bubble bursting and UV radiation on TEP in the SML and Bulk water.

 In addition, I will be characterizing on a more complete scale, the composition of TEP in SML and Bulk water. Thus far gel particles have only been measured in relation to the amount of acidic polysacharides that are stainable by Alcian Blue (TEP) or protein-containing particles stainable by Coomassie Brilliant Blue (CSP). However, there are many other materials that form TEP and so I hope to use mass spectrometry methods to elucidate what components make up TEP and to use novel techniques to compare TEP, CSP and lipids.
