Southern Caribbean Sea measurements of oceanic methane (CH4), carbon dioxide (CO2), and ammonia (NH3) from the Cariaco Basin. Data collection began in November 1995 and is ongoing, conducted by researchers Mary Scranton, Yrene Astor, and Kent Fanning as part of the CARIACO project.
Use Cases
- Analyze temporal trends in CH4, CO2, and NH3 concentrations from the 1995 start date to identify seasonal cycles or long-term changes.
- Model relationships between gas concentrations and the specific sampling location (10.3°N, 64.4°W) to understand spatial dynamics in the Cariaco Basin.
- Correlate CO2 measurements derived from spectrophotometric pH and alkalinity data with other oceanic parameters to study carbon system dynamics.
- Use the continuous time-series of methane measurements from gas chromatography to investigate sources and sinks of this potent greenhouse gas.
Strengths
- Long-term time-series data collection spanning from 1995 to the present.
- Specific geographic focus on a single basin (Cariaco Basin) at coordinates 10.3°N, 64.4°W.
- Multiple gas species (CH4, CO2, NH3) measured with documented analytical methods.
Limitations
- Unknown total row count and sampling frequency.
- Limited geographic scope to a single location in the Southern Caribbean Sea.
- Data completeness and potential gaps for individual measurements (e.g., NH3 method unspecified) are unknown.
