Seafloor Hydrostatic Pressure Measurements from Western Ionian Sea

Pressure gauge data from the INAF/NEMO-SN1 seafloor observatory measures hydrostatic pressure at a 15-second sampling interval. Francesco Chierici collected this data in 2012 as part of the SMO project within the EMSO network. The dataset captures pressure from the water column and atmospheric influence at a site east of Sicily.

Use Cases

• Analyze hydrostatic pressure time-series to study tidal patterns and sea level variations.
• Investigate the relationship between atmospheric pressure and total measured pressure at the seafloor.
• Model water column height changes by subtracting atmospheric pressure from the gauge measurements.
• Correlate pressure anomalies with seismic or volcanic activity in the tectonically active Ionian Sea region.
• Validate and calibrate oceanographic models using high-frequency (1 sample/15 sec) seafloor sensor data.

Strengths

• Data collected at a high temporal resolution of 1 sample every 15 seconds.
• Sourced from a dedicated seafloor observatory (NEMO-SN1) within the established EMSO network.
• Specific sensor model (Paroscientific 8CB-4000-I) and geographic location (Western Ionian Sea) are documented.

Limitations

• Sample size, total rows, and data volume are unknown.
• Dataset is from a single year (2012), limiting analysis of long-term trends.
• Potential for sensor drift or calibration issues common in long-term seafloor deployments is not described.
