Distribution and drivers of transparent exopolymer particles (TEP) and Coomassie stainable particles (CSP) in the ocean
Tesi per compendi de publicacions Transparent exopolymer particles (TEP) and Coomassie stainable particles (CSP) are operationally defined as organic particles > 0.4 µm that are stainable with the dyes Alcian Blue (specific for acidic polysaccharides) and Coomassie Brilliant Blue (specific for pr...
