CLIVAR Project LADCP Ocean Current Measurements 2003-2014

NOAA_NCEI's CLIVAR LADCP dataset contains estimates of deep ocean absolute currents and shear collected from 2003 to 2014. Measurements were obtained using Acoustic Doppler Current Profilers lowered on CTD rosette frames across multiple research cruises. The collection represents 20 years of evolving data acquisition and processing techniques for measuring full-depth water velocities.

Use Cases

• Analyzing deep ocean current velocity and shear profiles using LADCP beam measurements.
• Studying climate variability by correlating current data with ancillary CTD, GPS, and navigation data.
• Calibrating or validating shipboard ADCP and other oceanographic models with in-situ current profiles.
• Investigating long-term changes in ocean circulation patterns across the CLIVAR project's temporal span.

Strengths

• Data spans a significant temporal range, covering approximately 20 years of oceanographic cruises.
• Collection includes ancillary data streams (CTD, GPS, navigation) to improve processed current estimates.
• Represents a multi-institutional effort assembled at the University of Hawaii and Lamont-Doherty Earth Observatory.

Limitations

• Critical metadata conflicts exist: last update dates are reported as both 2014-05-05 and 2026-03-05.
• Specific row counts, column names, and dataset size are unknown across all platforms.
• Older datasets may have inconsistent organization, naming, or missing ancillary information.
