Amundsen Sea Water Temperature, Salinity, and Oxygen Data from a Mooring, 2016-2018

From 2016-01-28 to 2018-01 18, this dataset contains water temperature, salinity, dissolved oxygen, and pressure measurements recorded by CTD instruments from a mooring in the Amundsen Sea, Antarctica. It is a contribution to the Southern Ocean Observing System and was collected by the research vessel ice breaker Araon. Data are provided in ASCII (cnv) format.

Use Cases

• Analyze seasonal and interannual variability in Antarctic water masses based on temperature and salinity time series.
• Model dissolved oxygen distribution and potential hypoxic zones based on oxygen concentration data.
• Study vertical water column structure and ocean stratification based on pressure-depth profiles.
• Validate regional oceanographic models for the Amundsen Sea based on in-situ mooring measurements.

Strengths

• Data covers a two-year continuous time series from 2016-01-28 to 2018-01-18.
• Includes core oceanographic variables (temperature, salinity, oxygen, pressure) from a fixed Antarctic location.
• Dataset is a formal contribution to the Southern Ocean Observing System, suggesting a standardized collection protocol.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2018-01-18 00:00:00; freshness should be verified.
• Row count and file size are unknown, which may limit suitability assessment.
