Canadian Arctic Archipelago surface underway data collected aboard the CCGS Amundsen from July to October 2011. The dataset includes partial pressure of carbon dioxide (pCO2), barometric pressure, sea surface salinity, and sea surface temperature. Data were collected using a CO2 gas analyzer and shower head chamber equilibrator for autonomous CO2 measurement.
Use Cases
- Analyze carbon dioxide exchange between ocean and atmosphere based on pCO2 measurements.
- Study seasonal changes in Arctic sea surface temperature and salinity.
- Model regional carbon budgets based on continuous underway measurements.
- Correlate atmospheric pressure with oceanographic conditions in the Arctic Archipelago.
Strengths
- Data covers a specific cruise from 2011-07-18 to 2011-10-16, providing a continuous time series.
- Includes multiple related parameters: pCO2, barometric pressure, salinity, and temperature.
- Instruments used are specified: CO2 gas analyzer and shower head chamber equilibrator.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Last updated 2011-10-16; freshness should be verified.
