ADCP Current Velocity Timeseries for Newfoundland Coast of Bays (2009-2014)

73 Acoustic Doppler Current Profiler timeseries collected between 2009 and 2014, with individual records spanning from 26 to 235 days. The dataset contains horizontal and vertical current speed, direction, water depth, and temperature measurements from moorings deployed by Fisheries and Oceans Canada. It was compiled to establish an oceanographic baseline for sustainable aquaculture regulation in the region.

Use Cases

• Analyze horizontal current speed and direction patterns to model water circulation for aquaculture site planning.
• Correlate vertical current speed and temperature at instrument depth to study seasonal stratification and mixing processes.
• Use water depth and current velocity data to validate hydrodynamic models of the Coast of Bays, Newfoundland.

Strengths

• Contains 73 distinct timeseries records, providing multiple observation points.
• Covers a multi-year temporal range from 2009 to 2014, capturing inter-annual variability.
• Includes key oceanographic variables like current speed, direction, depth, and temperature for a comprehensive physical profile.

Limitations

• Timeseries lengths are inconsistent, varying from 26 to 235 days, complicating uniform time-series analysis.
• Data is temporally stale, with the latest collection ending in 2014, limiting relevance to present-day conditions.
• Specific data resolution (e.g., sampling frequency) and column structure are not detailed in the provided metadata.
