The ‘ozone hole’ has caused an increase in ultraviolet B radiation (UV-B, 280–320 nm) penetrating Antarctic coastal marine ecosystems, however the direct effect of this enhanced UV-B on pelagic organisms remains unclear. Oxidative stress, the in vivo production of reactive oxygen species to levels h...
