Data from the Australian Ocean Data Network accompanies a 2026 study on the resilience of the habitat-forming seaweed Phyllospora comosa. The dataset contains results from a laboratory culture experiment testing growth and physiological responses of seaweed juveniles to marine heatwaves, ocean warming, and acidification. The experiment used a collapsed factorial design with treatments simulating current and future ocean conditions, including a seven-day recovery period.
Use Cases
- Modeling seaweed physiological resilience based on photosynthetic and respiration rate data.
- Analyzing adjustments in fatty acid saturation as a potential tolerance mechanism to combined stressors.
- Investigating the down-regulation of carbon-concentrating mechanisms in future ocean conditions using δ13 C values.
Strengths
- Data is from a controlled laboratory experiment with a defined collapsed factorial design.
- Includes measurements from both during heatwave exposure and after a seven-day recovery period.
- Covers multiple physiological responses: net photosynthesis, respiration, growth, and fatty acid composition.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data is from a single species (Phyllospora comosa) from a specific geographic range (43 - 31° S).
