Seafloor Pressure Gauge Measurements from the Iberian Margin

Absolute pressure values were recorded by a Paroscientific 8CB-4000-I sensor on the GEOSTAR seafloor platform. Data was collected at a 15-second sampling interval with a resolution of 0.01 millibar. The dataset was created by Davide Embriaco as part of the NEAREST project and last updated in April 2008.

Use Cases

• Analyze tidal and non-tidal pressure variations from absolute pressure time-series data.
• Detect transient seafloor deformation events by examining pressure anomalies at 0.01 mbar resolution.
• Calibrate oceanographic models using high-frequency (15-second) sea-bottom pressure measurements.
• Study pressure-driven processes in the Gulf of Cadiz by correlating this data with other EMSO network observations.

Strengths

• High-resolution pressure measurements with a precision of 0.01 millibar.
• High-frequency time-series data sampled every 15 seconds.

Limitations

• Dataset size, row count, and temporal coverage are unknown.
• Data is from 2007-2008 and may be temporally stale for current research.
• Geographic scope is limited to a single site in the Gulf of Cadiz.
