Respiration Chamber Data for Marine Organisms with Physical Parameters and R Scripts

A 2015 dataset from the Australian Antarctic Data Centre contains raw and processed logs, spreadsheets, and R scripts from respiration and PAM (Pulse-Amplitude-Modulation) chamber experiments. It includes measurements of dissolved oxygen, photosynthetically active radiation (PAR), temperature, salinity, and chlorophyll fluorescence for control and acidified treatments. The collection features raw sensor logs, cleaned Excel files, and rapid light curve data for physiological analysis.

Use Cases

• Modeling respiration rates based on dissolved oxygen (DO) and temperature time-series data.
• Analyzing photosynthetic efficiency and stress responses using PAM-derived fluorescence parameters (F0, Fm, Yield).
• Calibrating or validating chlorophyll estimates from the uncalibrated rChl parameter with other measurements.
• Studying pump cycle dynamics and chamber acclimatization programs using the provided R script.

Strengths

• Includes both raw sensor logs and cleaned, analysis-ready Excel files for direct use.
• Contains a companion R script for processing pump cycles, aiding reproducibility.
• Provides detailed notes explaining program steps and sensor abbreviations for context.

Limitations

• Last updated 2015-02-23; freshness should be verified.
• Row count and file sizes are unknown, which may limit suitability assessment.
• Some column documentation references an external 'aquation manual' not included with the data.
