TL;DR: Using leaching experiments, the authors show that plastics release dissolved organic carbon into the ambient seawater that is rapidly taken up by marine microbes stimulating their growth, which alters the composition and activity of the base of the marine food webs.

TL;DR: In this paper, a comparative exploration of the biogeographical characteristics of different sub-regions comprising the Canary Current upwelling ecosystem (CanC) is presented, and it is shown that variability in coastline configuration, shelf width, coastal upwell, nutrient fertilization, productivity, or retentive vs. dispersive physical mechanisms may help explain subregional differences in fish distributions and abundances in the CanC.

TL;DR: Using axenic cultures, it is demonstrated unequivocally that phytoplankton can directly contribute to the autochthonous production of colored humic-like substances in the ocean.

TL;DR: Fluorescence excitation-emission matrices of CDOM can be a helpful tool for the identification of microbial sources of DOM in the marine environment, but further studies are necessary to explore the association of particular bacterial groups with specific fluorophores.

TL;DR: In this article, an intensive collection of hydrographic data was carried out at a single station on the shelf off the western coast of Galicia during the 1989 Galicia X cruise, from May to October 1989.
