Antarctic Phytoplankton Lipid Response to UV-B Radiation, 1996

A 1996 experimental dataset from the Australian Antarctic Data Centre examines the effects of UV-B radiation on the fatty acid, lipid, and sterol composition of three Antarctic phytoplankton species. Cultures of Odontella weissflogii, Chaetoceros simplex, and Phaeocystis antarctica were grown at 2 (±1)°C and exposed to controlled levels of PAR, UV-A, and low or high UV-B. The data likely contains species-specific measurements of nutritional changes induced by different radiation treatments.

Use Cases

• Modeling the impact of UV radiation on Antarctic food web nutritional quality based on described lipid and fatty acid changes.
• Comparing species-specific stress responses in phytoplankton based on the described experimental treatments of Odontella weissflogii, Chaetoceros simplex, and Phaeocystis antarctica.
• Analyzing the relationship between UV-B irradiance levels and cellular lipid composition changes described for the three species.

Strengths

• Experimental conditions are precisely documented, including temperature (2 ±1°C), PAR (16.3 ±0.7 W.m-2), and UV-A/B irradiance levels.
• Data covers three distinct Antarctic phytoplankton species (two diatoms and one haptophyte) isolated from Prydz Bay.
• Calibration details for measurement equipment (International Light IL 1700 Radiometer) are provided.

Limitations

• Last updated 1996-03-31 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
