Robin D Calfee
Robin Calfee is a Research Biologist at the Columbia Environmental Research Center.
Since joining the USGS in 1991, Robin has devoted her career to investigating the impacts of contaminants to various aquatic organisms and developing methods for quantifying fish swimming behavior. Currently, her research focuses on testing the effectiveness of different control strategies for Asian Carp such as auditory stimuli, food attractants and supplemental capture techniques.

The effects of ultraviolet-B radiation on the toxicity of fire-fighting chemicals The effects of ultraviolet-B radiation on the toxicity of fire-fighting chemicals
The interactive effects of ultraviolet (UV) and fire-retardant chemicals were evaluated by exposing rainbow trout (Oncorhyncus mykiss) juveniles and tadpoles of southern leopard frogs (Rana sphenocephala) to six fire-retardant formulations with and without sodium ferrocyanide (yellow prussiate of soda [YPS]) and to YPS alone under three simulated UV light treatments. Yellow prussiate of...

The role of the egg jelly coat in protecting Hyla regilla and Bufo canorus embryos from Ultraviolet B radiation during development The role of the egg jelly coat in protecting Hyla regilla and Bufo canorus embryos from Ultraviolet B radiation during development
Background. Previous studies have suggested that Ultraviolet B (UVB) radiation may play a role in amphibian population declines. Some of these studies also indicate that egg hatching success is unaltered in some species of anurans as a result of UVB exposure. It has been proposed that the egg mass jelly provides photoprotection to the developing embryos. Methods. Direct...

Quantifying solar spectral irradiance in aquatic habitats for the assessment of photoenhanced toxicity Quantifying solar spectral irradiance in aquatic habitats for the assessment of photoenhanced toxicity
The spectra and intensity of solar radiation (solar spectral irradiance [SSI]) was quantified in selected aquatic habitats in the vicinity of an oil field on the California coast. Solar spectral irradiance measurements consisted of spectral scans (280–700 nm) and radiometric measurements of ultraviolet (UV): UVB (280–320 nm) and UVA (320–400 nm). Solar spectral irradiance measurements...

Assessment of the photoenhanced toxicity of a weathered oil to the tidewater silverside Assessment of the photoenhanced toxicity of a weathered oil to the tidewater silverside
Studies were conducted to determine the interactive toxicity of a water-accommodated fraction (WAF) of a weathered middle distillate petroleum and solar radiation to an estuarine organism, the tidewater silverside (Menidia beryllina). Juvenile silversides were monitored for survival and growth during a 7-d static renewal exposure to dilutions of WAFs of an environmentally weathered oil...

Photoenhanced toxicity of weathered oil to Mysidopsis bahia Photoenhanced toxicity of weathered oil to Mysidopsis bahia
The toxicity of a water-accommodated fraction (WAF) prepared from weathered oil was assessed in a 7-day static renewal test with Mysidopsis bahia. Weathered oil was collected from the 5 x monitoring well at the Guadalupe oil field. Solar ultraviolet and visible light intensities were measured in various habitats in the vicinity of the weathered oil sample collection site, and the...

Photoenhanced toxicity of a weathered oil on Ceriodaphnia dubia reproduction Photoenhanced toxicity of a weathered oil on Ceriodaphnia dubia reproduction
Traditionally, the toxic effects of petroleum have been investigated by conducting studies in the absence of ultraviolet radiation (UV). Photomediated toxicity is often not considered, and the toxic effects of an oil spill can be grossly underestimated. The toxicity of a weathered oil collected from a monitoring well at an abandoned oil field toCeriodaphnia dubia was examined in the...
