Abstract by author:
The results have shown that the level of UVR in the low latitude or tropical regions (Namibia) is relatively high 8 or times compare to high latitude regions (Norway). The PAR value of 0. 01 in µmole quanta cm-2, in the low latitude (Benguela) penetrates deeper up to 15m and below. The general trends of phytoplankton distribution follow the pattern distribution of UVR and temperatures
