Coastal Ocean Currents And Salinity Off Oahu In 2010

250MB of continuous oceanographic data captures currents, temperature, and salinity from the surface to 1000 meters depth off southwest Oahu. The dataset includes Acoustic Doppler Current Profiler (ADCP) records and Conductivity-Temperature-Depth (CTD) sensor readings from a seven-month deployment in 2010. The mooring was sponsored by the Naval Facilities Command and involved researchers from the University of Hawaii.

Use Cases

• Analyze vertical current profiles from ADCP data between 50m and 950m depth for coastal circulation patterns.
• Correlate temperature and salinity readings from CTD sensors at seven discrete depths (20m to 1000m) with current data.
• Model water mass properties and stratification using the continuous seven-month time series of physical oceanographic variables.
• Validate regional ocean models with high-resolution in-situ measurements from a fixed coastal location near the 1600m isobath.

Strengths

• Continuous seven-month time series from May to December 2010.
• Vertical coverage spans from near-surface to 1000 meters depth.
• Data described as clean and not requiring filtering or de-spiking.

Limitations

• Data is from a single location and year, limiting spatial and temporal generalizability.
• Sample size and specific row/column counts are unknown.
• Data is over a decade old, potentially not reflecting current ocean conditions.
