TL;DR: The observations indicate that the surface microlayers are largely heterotrophic microcosms, which can be as rich as laboratory cultures, and that an appreciable part of the dissolved organic carbon is carbohydrate of phytoplankton origin, released and brought to the surface by migrating and excreting phagotrophic protists.
Journal ArticleDOI
Estimation of in situ rates of heterotrophy using diurnal changes in dissolved organic matter and growth rates of picoplankton in diffusion culture
TL;DR: A scheme has been developed for observing diurnal changes in dissolved organic matter in the photic zone and correlating the with specific microbial fractions and their rates of growth and uptake, and polysaccharide and monosaccharide maxima were mainly associated with phagotrophic protists.
Journal ArticleDOI
Dissolved carbohydrate and microbial ATP in the North Atlantic: concentrations and interactions
TL;DR: A selective and sensitive spectrophotometric assay for monosaccharide before and after a hydrolysis step has permitted the estimation of total carbohydrate (TCHO) and of polysaccharide (PCHO) by difference.
