Description
Results from 11 bioassays conducted in 2014 assess the toxicity of five metals (copper, cadmium, lead, zinc, nickel) on two species of Antarctic marine microalgae. The dataset includes 7 tests with Phaeocystis antarctica and 4 tests with Cryothecomonas armigera, measuring growth rates, cell density, and other physiological parameters under controlled conditions. Data was aggregated by the Australian Antarctic Data Centre (AU_AADC) and published on NASA's Earthdata platform.
Use Cases
Modeling dose-response relationships for metal toxicity based on reported concentration ranges and growth rate percentages.
Comparing species sensitivity between Phaeocystis antarctica and Cryothecomonas armigera based on the described test results.
Analyzing the effects of environmental conditions (temperature, light, salinity) on toxicity outcomes as detailed in the test protocols.
Training predictive models for algal growth inhibition using the multi-metal, multi-species experimental data.
Strengths
Includes 11 distinct bioassays with 3-5 replicates per treatment, providing a basis for statistical analysis.
Reports specific test conditions (temperature, light, salinity, pH) and metal concentration ranges for reproducibility.
