The profiles include natural fluorescence (upwelled radiance at 683 nm), scalar irradiance (photosynthetically active radiation (PAR), computed primary production (pp), diffuse attenuation coefficient, and UVB (308 and 320 nm) and UVA (340 and 380 nm) radiation and ocean temperature all measured as a function of depth from 21/1/94 to 673/94. Fifteen stations in the Antarctic waters (69?53' to 70?02'S) and 6 en route (64?53' to 30?01'S) were analysed. The average values for surface chlorophyll a and pp were higher for temperate than for Antarctic waters (1.68 mg/m3 and 216.56 mgC/m3 /d respectively). The values for column chlorophyll (22.48 mg/m2) and primary productivity (1023.79 mgC/m2 /d) in the Antarctic waters however, were 2.14 and 1.5 times higher than those in temperate waters. A profiling underwater radiometer (Biospherical Instruments Inc. San Diego, CA, USA) was used to procure data on chlorophyll a (chl a) derived from natural fluorescence (upwelled radiance at 683 nm, scalar irradiance-PAR (photosynthetically available radiation), diffuse attenuation coefficient (K), computed primary production (pp), UVB and UVA radiation as function of depth from 15 stations in the Antarctic waters (69?53 to 70?02S) and 6 stations from Temperate waters (64?53S to 30?01S). The instrument enables to assess the effect of sub-surface transmission of UVR in aquatic environments.
