| Summary: | ductivity-determining biophysical interactions occur in the upper 0 to 30 m of the water column. The eggs and larvae of several commercially important marine inver-tebrates and fishes (e.g. Gadus morhua L.) are found in this layer. Measurements of the diuse attenuation co-ecients for ultraviolet-B radiation (280 to 320 nm, UV-B) at various locations in this geographic region indicated maximum 10 % depths (the depth to which 10 % of the surface energy penetrates at a given wave-length) of 3 to 4 m at a wavelength of 310 nm. This represents a significant percentage of the summer mixed-layer water column: organisms residing in this layer are exposed to UV-B radiation. Laboratory experiments using a Xenon-arc-lamp based solar simulator revealed that cod embryos exposed to UV-B exhibited high |
