Musicians Seamounts Expedition Oceanographic and Meteorological Data

Oceanographic data from a NOAA expedition mapping the Musicians Seamounts chain up to 650 nautical miles north of Hawaii. The dataset includes shipboard sensor measurements for navigation, meteorology, and oceanography collected from August 8 to August 31, 2017. It is produced by the National Oceanic and Atmospheric Administration and is available on multiple government data platforms.

Use Cases

• Mapping seafloor bathymetry and seamount structures using navigation and bathymetric data.
• Analyzing sea surface conditions via thermosalinograph, remote temperature, and sound velocity probe measurements.
• Studying atmospheric-ocean interactions using wind, air temperature, humidity, and barometric pressure columns.
• Investigating the hydrographic properties of the North Pacific Subtropical Gyre region.

Strengths

• Data collected during a dedicated mapping expedition with strategic transits over a specific geological feature.
• Includes real-time, hourly data transfer via high-bandwidth satellite, enabling near-real-time shore access.
• Covers a wide geographical area extending from Hawaiian waters to international waters 650 nm north.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Conflicting last-update dates exist between platforms (2017-08 31 vs. 2026-04-01), indicating potential metadata inconsistency.
• The license governing data use is not specified.
