Seawater temperature and sea level pressure measurements are recorded by two tide gauge sensors moored at Deception Island. Data collection began in 2012, with continuous records since 2016, providing a 10-minute resolution time series. The GEO2OCEAN project, led by Dr. Manuel Berrocoso Domínguez of the University of Cadiz, is responsible for this oceanographic monitoring.
Use Cases
- Analyze seawater temperature time series for seasonal and interannual variability in Antarctic coastal waters.
- Correlate sea level pressure records with local atmospheric conditions and storm events.
- Validate regional climate or ocean circulation models using high-resolution in-situ sensor data.
- Study long-term trends in polar oceanographic parameters from a decade-long monitoring station.
Strengths
- Continuous data records with no gaps since 2016.
- High temporal resolution with measurements recorded every 10 minutes.
- Long-term oceanographic time series initiated in 2012.
Limitations
- Data is raw and unprocessed, requiring user-side quality control.
- Geographic coverage is limited to a single location at Deception Island.
- Data collection is annual and occurs only during the austral summer, though sensors record continuously.
