Australian Antarctic Ship Underway Data for Southern Ocean Voyages Since 1985

Underway environmental data collected by Australian Antarctic Division chartered vessels moving through the Southern Ocean. The collection began in 1985 on the Nella Dan and includes meteorological and oceanographic parameters like sea surface temperature and salinity, as well as ship parameters like position and speed. Data for individual voyages can be extracted in various formats via the Marine Science Underway Data Tool.

Use Cases

• Modeling sea surface temperature trends in the Southern Ocean based on the described oceanographic parameters.
• Analyzing ship track patterns and voyage frequency based on positional and heading data mentioned in the description.
• Studying correlations between atmospheric conditions (e.g., air temperature, humidity, UV levels) and oceanographic states from the described meteorological data.
• Creating time-series visualizations of environmental conditions along specific Antarctic voyage routes.

Strengths

• Data collection spans a long temporal range, beginning in 1985.
• Covers multiple environmental domains, including oceanographic and meteorological parameters as described.
• Data is associated with specific Antarctic seasons and voyage numbers, providing structured temporal context.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The type and consistency of data collected varies depending on the vessel and its sensors.
