Seafloor Pressure Gauge Measurements from the Gulf of Cadiz

Absolute pressure data was collected from the Iberian Margin site in the Gulf of Cadiz using a Paroscientific 8CB-4000-I sensor. Measurements were taken every 15 seconds with a resolution of 0.01 millibar. The data was gathered by the INGV/GEOSTAR seafloor platform as part of the ESONET-NOE-LIDO project within the EMSO network and last updated in July 2010.

Use Cases

• Analyze temporal patterns in absolute pressure values to detect seafloor deformation or seismic events.
• Calibrate oceanographic models using high-resolution (0.01 mbar) pressure measurements from a fixed sea-bottom station.
• Study short-term pressure variability in the Gulf of Cadiz using data sampled at 15-second intervals.
• Integrate pressure time-series data with other geophysical datasets from the EMSO network for multi-parameter analysis.

Strengths

• High temporal resolution with a 15-second sampling interval.
• High measurement precision with a resolution of 0.01 millibar.

Limitations

• Dataset temporal coverage and total row count are unknown.
• Data is over a decade old, with the last update recorded in July 2010.
• Geographic scope is limited to a single site in the Gulf of Cadiz.
