NOAA Okeanos Explorer Oceanographic and Bathymetric Survey Data

Data collected from NOAA Ship Okeanos Explorer during the EX1004 Leg 1 expedition in the Philippine Sea from June 8 to June 20, 2010. The dataset includes ship navigation, sensor profiles, and multibeam bathymetry from a transit from Guam to Bitung. It is produced by the National Oceanic and Atmospheric Administration, Department of Commerce.

Use Cases

• Mapping seafloor topography using Multibeam Bathymetric Data.
• Analyzing water column properties like conductivity, temperature, and depth (CTD) from sensor profiles.
• Studying ship navigation and environmental conditions using CNAV, Gyro, DGPS, and Met (meteorological) data.
• Investigating marine habitats and biodiversity through data collected in coral and seep regions.

Strengths

• Dataset includes a wide array of sensor types: navigation (CNAV, Gyro), environmental (CTD, Met, Wind), and bathymetric systems.
• Collected during a dedicated ocean exploration expedition (EX1004) with a clear temporal focus of 13 days in 2010.
• Provenance from a major national agency (NOAA, Department of Commerce) supports authority.

Limitations

• Critical metadata conflicts exist: last updated date is listed as both 2010-06-20 and a future date of 2026-04-01.
• No concrete row counts, file sizes, or specific column names are provided across any platform.
• License information is not specified.
