NOAA Okeanos Explorer Expedition Data from the Molucca and Philippine Seas

NOAA Ship Okeanos Explorer collected 21 days of oceanographic data during a 2010 expedition in the Molucca and Philippine Seas. The National Centers for Environmental Information archives this dataset, which includes ship navigation, sensor profiles, and multibeam bathymetry. Data collection occurred from June 24 to July 14, 2010.

Use Cases

• Map seafloor bathymetry using Multibeam Bathymetric Data to identify underwater features.
• Analyze water column properties like temperature and salinity from CTD (Conductivity, Temperature, Depth) sensor profiles.
• Correlate ship position from CNAV and DGPS data with sensor readings for spatiotemporal analysis.
• Study meteorological conditions at sea using Met (Meteorological) and Wind sensor time-series data.
• Track research operations and sampling events using the EventData log from the expedition.

Strengths

• Data spans a 21-day continuous expedition from 2010-06-24 to 2010-07-14.
• Includes multiple complementary data streams: navigation, sensor profiles, bathymetry, and meteorological readings.

Limitations

• Specific row counts, file sizes, and column details for each data stream are unknown.
• Data is from a single, short-duration expedition in 2010, limiting temporal and geographic scope.
