POTENTIAL EFFECTS OF UV‐B RADIATION ON MARINE ORGANISMS OF THE SOUTHERN OCEAN: DISTRIBUTIONS OF PHYTOPLANKTON AND KRILL DURING AUSTRAL SPRING
Abstract Increases in UV‐B radiation resulting from ozone depletion during austral spring could potentially alter the balance of the Southern Ocean marine ecosystem. A quantitative assessment ol the effects of UV‐B enhancement requires knowledge of (1) the wavelength‐dependent fluxes of UV‐B in the...
