1992 data from a study analyzing the chemical composition of peat deposits from Macquarie Island. The dataset contains measurements of mono- and dicarboxylic acids, categorized by saturation state, from samples subjected to hydrothermal pyrolysis at four temperatures. It was produced by researchers S. A. Pickering and B.D. Batts based on samples collected at Green Gorge.
Use Cases
- Analyze the relationship between pyrolysis Temperature and the yield of Monocarboxylic Acids versus Dicarboxylic Acids.
- Model the distribution of Saturated versus Unsaturated carboxylic acid compounds across different thermal treatments.
- Investigate biomarker patterns in peat for paleoenvironmental reconstruction using the acid concentration data.
- Study the thermal stability and transformation of organic matter by correlating Temperature with acid functional group ratios.
Strengths
- Data derived from a peer-reviewed publication in Org. Geochem. J., 18, 683-693, (1992).
- Experimental design includes four controlled pyrolysis Temperature levels (95, 120, 200, and 300 °C).
- Samples have precise geographic coordinates (54°37'S 158°37'10"E) for spatial context.
Limitations
- Sample size and row count are unknown, potentially limiting statistical power.
- Data is from a single 1992 study, representing a specific temporal snapshot.
- Limited to analysis by Size Exclusion Chromatography; other analytical methods are not included.
