Dose and dose-rate dependency in the mortality response of Calanus finmarchicus embryos exposed to ultraviolet radiation
Browman, Howard I.; St-Pierre, Jean-François; Kuhn, Penelope S. (Journal article; Peer reviewed, 2003-02-04)In previous work, we reported that embryos of Calanus finmarchicus exposed to artificial ultraviolet-B (UV-B) radiation exhibited high wavelength-dependent mortality. The strongest effects occurred under exposures to ... -
Impact of ultraviolet radiation on marine crustacean zooplankton and ichthyoplankton: a synthesis of results from the estuary and Gulf of St. Lawrence, Canada
Browman, Howard I.; Rodriguez, Carolina Alonso; Béland, France; Cullen, John J.; Davis, Richard F.; Kouwenberg, Juliana H. M.; Kuhn, Penelope S.; McArthur, Bruce; Runge, Jeffrey A.; St-Pierre, Jean-François; Vetter, Russell D. (Journal article; Peer reviewed, 2000-06-26)The objectives of the research program reported upon here were (1) to measure ambient levels of UV radiation and determine whichvariables most strongly affected its attenuation in the waters of the estuary and Gulf of St. ... -
UV (280 to 400 nm) optical properties in a Norwegian fjord system and an intercomparison of underwater radiometers
Kjeldstad, Berit; Frette, Øyvind; Erga, Svein Rune; Browman, Howard I.; Kuhn, Penelope S.; Davis, Richard F.; Miller, William; Stamnes, Jakob J. (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 ...
