The existence of a size-reactivity continuum of DOM - observations and measurements showing that High molecular weight (HMW) DOM tends to be younger and more reactive than lower MW DOM - has been demonstrated in laboratory and field investigations in different parts of the ocean. A mechanistic explanation for the greater reactivity of HMW DOM has been lacking, however.     Here we investigated the potential of seawater microbial communities from different water masses and under differing conditions of organic matter availability to hydrolyze six high-molecular-weight polysaccharides (arabinogalactan, chondroitin sulfate, fucoidan, laminarin, pullulan, and xylan). Samples were taken from incubation experiments of deep chlorophyll maximum (DCM), oxygen minimum zone (OMZ), and bottom waters aboard R/V Endeavor (EN638), May 2019 in the Northern Atlantic.   This dataset includes the measurement of polysaccharide hydrolase activities from samples taken from mesocosm incubations after the addition of HMW DOM.
