NOAA Sea Bottom Pressure Gauge Time Series Data (1976-1989)

Time series measurements of seawater pressure from anchored or bottom-mounted sensors provide information on tidal and storm flows and ocean circulation. The dataset contains values of total pressure, position, bottom depth, and gauge depth for each station, typically reported at 10-15 minute intervals. It was produced by the National Oceanic and Atmospheric Administration and covers the period from 1976 to 1989.

Use Cases

• Analyzing tidal patterns and storm surge impacts using time-series pressure measurements.
• Studying ocean circulation by examining pressure variations at different depths and locations.
• Calibrating or validating hydrodynamic models with in-situ sea bottom pressure data.
• Investigating long-term changes in sea surface elevation from pressure signatures recorded between 1976 and 1989.

Strengths

• Data provides a consistent 13-year temporal coverage from 1976 to 1989 for longitudinal analysis.
• Measurements include precise station metadata such as position, bottom depth, and gauge depth.
• Time-series data is reported at high-frequency intervals, typically every 10 to 15 minutes.

Limitations

• Critical metadata conflicts exist: the last update date is listed as both 1989-10-03 and a future date of 2026-04-01.
• Essential details like row count, file size, specific column names, and data license are unavailable from all sources.
• The dataset's age means it may not reflect current oceanographic conditions or use modern sensor technology.
