Temporal covariation of DNA damage in Antarctic ichthyoplankton with ambient UVB flux during austral spring of 1994. CPD levels (CPD per Mb of DNA; mean ± SEM) for icefish (C. aceratus) eggs (A, •) and for larval icefish heads (B, ▵) and bodies (C, ▾) are plotted vs. date of specimen capture. Biologically weighted cumulative daily solar UVB (Hunter’s UVB), measured at Palmer Station, is indicated by the solid line in each panel.
