Biological weighting functions quantify the wavelength-dependent effects of ultraviolet radiation on DNA damage in larvae of several Antarctic marine invertebrates. Data was generated by exposing embryos and larvae to artificial light with specific wavelength filters over three days and analyzing for cyclobutane pyrimidine dimers. The dataset was produced by the organization SCIOPS and last updated in December 2004.
Use Cases
- Model species-specific effects of ozone depletion by applying biological weighting functions to ambient spectral irradiance data.
- Compare UVR sensitivity across embryonic stages (eggs, blastula, 4-armed larvae) for the species Sterechinus.
- Analyze DNA damage (cyclobutane pyrimidine dimers) resulting from exposure to specific wavelength cut-offs (280nm, 305nm, 320nm, 375nm, 400nm).
- Calculate biological effective irradiance for a given light environment using the provided spectral weighting functions.
Strengths
- Includes biological weighting functions for multiple species (Sterechinus, Acodantaster, Perknaster, Parbolarsis).
- Experimental design used five specific wavelength filter treatments (50% cut-off at 280, 305, 320, 375, 400nm).
- Data supports modeling of stage-specific effects for three distinct embryonic stages of Sterechinus.
Limitations
- Dataset is temporally stale, with no updates since 2004.
- Sample size and specific row/record counts are unknown.
- Geographic coverage is limited to McMurdo Sound, Antarctica.
