The communities of marine bacteria that assemble around living microphytoplankton are predictably dominated by three taxonomic groups, each of which specializes in different components of the available metabolite pool: Rhodobacterales transport small and polar metabolites, Flavobacteriia use carb...

Polar regions are an under-studied environment within the global ocean, with seawater found under sea ice particularly under-sampled. This project provides concentrations of select dissolved organic carbon compounds found in under-ice seawater sampled between March and May 2023. The dissolved org...
