Antarctic Coastal Sea Level and Meteorological Measurements Near Scott Base

2001 to 2012 sea level, air temperature, and barometric pressure data logged at 5-minute intervals from a monitoring station near Scott Base, Antarctica. The dataset was collected and archived by SCIOPS, with annual calibration performed by Land Information New Zealand (LINZ). Measurements involve a sea level sensor, data logger, and validation using geodetic GPS receivers on sea ice and shore.

Use Cases

• Analyze tidal patterns and sea level anomalies from the 5-minute sea level column for the Ross Sea region.
• Correlate sea level fluctuations with local atmospheric conditions using the concurrent air temperature and barometric pressure columns.
• Validate satellite altimetry data or regional climate models with in-situ sea level measurements calibrated annually by LINZ.
• Study short-term meteorological events (e.g., storms) by examining high-frequency air temperature and pressure time series.
• Assess long-term trends in coastal Antarctic environmental variables across the 2001-2012 time range.

Strengths

• High temporal resolution with data recorded at 5-minute intervals.
• Multi-year coverage from 2001 to 2012, enabling trend analysis.
• Includes three concurrent physical measurements: sea level, air temperature, and barometric pressure.
• Data undergoes annual calibration by a national mapping agency (LINZ) using GPS validation.

Limitations

• Unknown total row count and dataset size.
• Geographic coverage is limited to a single station near Scott Base, Antarctica.
• Data is temporally stale, ending in 2012 with no confirmed updates.
