NOAA Okeanos Explorer New England Seamount Chain Bathymetric Survey

NOAA Ship Okeanos Explorer conducted a 24-hour multibeam and singlebeam mapping survey during the EX1303 expedition. The 3,937 nautical mile transit mapped the western New England Seamount Chain, covering 14 named seamounts. Data collection occurred from June 11 to June 29, 2013, to support the US Extended Continental Shelf program and scientific community requests.

Use Cases

• Analyzing seamount bathymetry and morphology for geological studies.
• Supporting Extended Continental Shelf (ECS) boundary delineation and research.
• Creating base maps for planning subsequent biological or chemical sampling expeditions.
• Studying seafloor features along a defined transit corridor in the North Atlantic.

Strengths

• Survey covers a specific, long transit corridor of 3,937 nautical miles.
• Expedition targeted 14 named seamounts, providing focused geographic coverage.
• Data collection was designed in consultation with ECS scientists, ensuring relevance.

Limitations

• Specific column names, row counts, and file sizes are not provided by any source.
• Sources conflict on the 'last updated' date, with one showing 2013 and another showing a future date of 2026.
• Available file format information is limited to HTML, suggesting the primary data may be accessed via metadata pages.
