Dose and dose-rate dependency in the mortality response of Calanus finmarchicus embryos exposed to ultraviolet radiation
(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 ... -
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 ... -
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 ... -
Impact of solar ultraviolet radiation on hatching of a marine copepod, Calanus finmarchicus
(Journal article; Peer reviewed, 2000-02-28)The calanold copepod Calanus finmarchicus 1s a key component of the zooplankton community in the estuary and Gulf of St. Lawrence, Canada. During the spring and summer months, C. firmarchicus eggs are released into the ... -
Impact of ultraviolet radiation on marine crustacean zooplankton and ichthyoplankton: a synthesis of results from the estuary and Gulf of St. Lawrence, Canada
(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
(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 ...
