Sound Velocity Profiles from North Atlantic Ocean Surveys 2024-2025

Sound velocity profiles were collected in Northern Massachusetts Bay during hydrographic surveys from August 2024 to March 2025. Data were gathered from multiple vessels including MV Northstar Challenger, RV North Cove, RV South Cove, RV Twister, and RV West Cove II. Profiles were recorded at intervals of approximately 2 hours for sound speed profilers and 15 minutes for moving vessel profilers.

Use Cases

• Analyze sound velocity profile variations over the survey period from August 2024 to March 2025.
• Compare sound velocity data collected at 15-minute intervals from moving vessel profilers with data from other profiler types.
• Map sound velocity characteristics across the Northern Massachusetts Bay geography for oceanographic modeling.
• Correlate sound velocity profiles with vessel-specific metadata from the five listed survey platforms.

Strengths

• Data covers a defined 8-month time range from 2024-08-03 to 2025-03-28.
• Profiles were collected at high temporal resolution, with moving vessel profiler data taken approximately every 15 minutes.
• Surveys were conducted from five distinct vessels, providing multiple data collection platforms.
• Data is provided in the structured netCDF format, suitable for scientific analysis.

Limitations

• The dataset's total volume, row count, and specific column structure are unknown.
• Data is limited to the specific geography of the Northern Massachusetts Bay and North Atlantic Ocean.
• The dataset's completeness and potential gaps during the 8-month period are not detailed.
