Major role of ultraviolet-B in controlling bacterioplankton growth in the surface layer of the ocean

Article Abstract:

New evidence shows that ultraviolet-B (UV-B) solar radiation suppresses the activity of bacterioplankton in the surface layer of the ocean at greater depths and to a greater degree than previously believed. UV-B also degrades macromolecules photochemically into biologically labile organic compounds. Since bacterioplankton account for the uptake of much labile organic matter, increased UV-B concentration may result in the increased concentration of labile organic matter in the surface layer of the oceans.
