Oceanographic data collected during the EX2102: 2021 Technology Demonstration (AUV & Mapping) expedition on NOAA Ship OKEANOS EXPLORER in the North Atlantic Ocean from 2021-05-14 to 2021-05-27 (NCEI Accession 0237317)

NOAA's 2021 technology demonstration expedition captured a multi-sensor oceanographic profile of the North Atlantic. Data acquisition from shipboard sensors includes navigational and meteorological measurements such as altimetry, conductivity, depth, fluorescence, oxygen, salinity, temperature, and wind speed. The National Centers for Environmental Information (NCEI) published this dataset from the May 2021 voyage.

Use Cases

• Modeling sea surface temperature anomalies using water_temperature and salinity time-series data.
• Analyzing correlations between wind_speed, relative_humidity, and other meteorological parameters.
• Calibrating acoustic mapping systems with concurrent depth, pressure, and sound_velocity measurements.
• Studying water column structure with profile data from CTD (Conductivity, Temperature, Depth) and XBT casts.
• Fusing navigational data with sensor readings for geospatial analysis of oceanographic conditions.

Strengths

• Data spans a focused 14-day period from May 14 to May 27, 2021, ensuring temporal consistency.
• Includes over 15 distinct sensor measurements, enabling multi-parameter analysis.
• Collected by the authoritative NOAA Ship Okeanos Explorer using standard oceanographic instrumentation.

Limitations

• The dataset's row count and total size are unknown, making it difficult to assess computational requirements.
• Limited to a specific two-week cruise in the North Atlantic, reducing generalizability to other regions or seasons.
