NASA Earthdata hosts physiological measurements from 23 non-incubating Adelie penguins subjected to environmental stresses. The dataset contains time-series observations of heart rate, blood oxygenation, cytochrome oxidase redox state, and peripheral blood flow, recorded via a visible/near-infrared optical spectrometer. Data was collected by the SCIOPS organization and last updated in December 1999.
Use Cases
- Modeling the relationship between observed stressor events and changes in heart rate and blood oxygenation levels.
- Analyzing time-series patterns in cytochrome oxidase redox state to understand metabolic response to handling and human presence.
- Correlating biometrics like beak length, flipper length, and weight with physiological stress responses to infer sex-specific patterns.
Strengths
- Data includes four core physiological metrics (heart rate, blood oxygenation, cytochrome oxidase redox, blood flow) per observation.
- Behavioral observations were recorded every minute, providing a detailed temporal context for stress events.
Limitations
- The sample size is limited to 23 individual birds.
- Data is from 1999 and may not reflect current methodologies or environmental conditions.
