NOAA Okeanos Explorer Gulf of Mexico and North Atlantic Oceanographic Expedition Data 2021

NOAA Ship Okeanos Explorer collected oceanographic data in the Gulf of Mexico and North Atlantic Ocean from April 16 to May 10, 2021. The dataset includes navigational, meteorological, and vehicle sensor data, along with profile data from CTD and XBT casts. The National Centers for Environmental Information (NCEI) archives this data.

Use Cases

• Modeling water column properties like salinity and temperature from CTD profile data.
• Analyzing correlations between meteorological features such as wind speed and sea surface temperature.
• Calibrating echo sounder and sound velocity data for bathymetric mapping applications.
• Studying ROV operational parameters like time to surface and traction winch data for mission planning.

Strengths

• Data collected over a 25-day continuous expedition in two major ocean regions.
• Includes multiple sensor streams: navigation, meteorology, vehicle telemetry, and profile data.

Limitations

• Specific row counts, column definitions, and sample sizes are unknown.
• Data is a single snapshot from 2021, limiting analysis of temporal trends.
