Effect of Sub-Lethal Exposure to Ultraviolet Radiation on the Escape Performance of Atlantic Cod Larvae (Gadus morhua)
(Journal article; Peer reviewed, 2012-04-19)The amount of ultraviolet (UV) radiation reaching the earth’s surface has increased due to depletion of the ozone layer. Several studies have reported that UV radiation reduces survival of fish larvae. However, indirect ... -
Effects of UV Radiation and Diet on Polyunsaturated Fatty Acids in the Skin, Ocular Tissue and Dorsal Muscle of Atlantic Salmon (Salmo salar) Held in Outdoor Rearing Tanks
(Journal article; Peer reviewed, 2010-07)The effect of UV radiation (UVR) on juvenile Atlantic salmon (Salmo salar) was assessed by measuring the fatty acid (FA) profiles of muscle, dorsal and ventral skin, and ocular tissues following 4-month long exposures to ... -
High survival of neustonic zoea I larvae of American lobster Homarus americanus following short-term exposure to ultraviolet radiation (280 to 400 nm)
(Journal article; Peer reviewed, 2000-02-28)Ultraviolet radiation (W-B = 280 to 320 nm; UV-A = 320 to 400 nm) is harmful to the planktonic early life stages of some marine organisms. In the Gulf of St. Lawrence, Canada, measurements of the diffuse attenuation ... -
UV (280 to 400 nm) optical properties in a Norwegian fjord system and an intercomparison of underwater radiometers
(Journal article; Peer reviewed, 2003-07-17)The depth to which solar ultraviolet (UV) radiation penetrates water columns is highly variable. The range in diffuse attenuation coefficients observed in the clearest ocean waters versus small oligotrophic lakes can be ... -
UV transmission in Norwegian marine waters: controlling factors and possible effects on primary production and vertical distribution of phytoplankton
(Journal article; Peer reviewed, 2005-12-23)We investigated the ultraviolet radiation (UVR) transmission properties of Norwegian oceanic, coastal and fjord waters, and how they influence the primary production and vertical distribution of phytoplankton. Values of ...
