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 to hydrolyze six high-molecular-weight polysaccharides: arabinogalactan, chondroitin sulfate, fucoidan, laminarin, pullulan, and xylan. This dataset includes measurement of polysaccharide hydrolase activities obtained from seawater incubations. Seawater samples were collected at various stations and depths in Kongsfjorden, an Arctic fjord near Ny-Ålesund, Svalbard, in April 2018.
