Munida_TS_RV_Polaris_II: Ocean Carbon and Temperature Time Series

NCEI Accession 0112883 contains time series data for surface ocean carbon dioxide partial pressure, salinity, and sea surface temperature. These data were collected from the RV Polaris II in the South Pacific Ocean between August 29 and October 24, 2006, as part of the Global CO2 Time-series and Moorings Project. The dataset contributes to international efforts coordinated by the UNESCO International Ocean Carbon Coordination Project (IOCCP) to monitor ocean carbon uptake.

Use Cases

• Analyzing temporal trends in ocean pCO2 based on high-resolution time-series measurements.
• Studying the relationship between sea surface temperature and carbon dioxide fugacity in the South Pacific.
• Validating ocean carbon cycle models using in-situ salinity and temperature data.
• Assessing regional ocean acidification dynamics from partial pressure of carbon dioxide measurements.

Strengths

• Data is part of a coordinated international project involving groups from 18 countries, suggesting standardized collection methods.
• Provides a focused, high-resolution time series over a nearly two-month period in 2006.
• Includes measurements from specific, named instruments (CO2 gas analyzer, shower head chamber equilibrator, thermosalinographs).

Limitations

• Key metadata such as row count, file size, specific column names, and license are unavailable across all sources.
• The last update date conflicts between sources (2006-10-24 vs. 2026-03-05), creating uncertainty about metadata maintenance.
• Dataset scope is limited to a single cruise in a specific region and time period.
