Supporting evidence — 5 representative gaps

• Deep differences: expanding the marine social sciences and humanities into the deep ocean (2026) · npj Ocean Sustainability · doi

  The deep ocean is inherently challenging to study due to its vastness - Only a very small percentage of the seabed and even less of the water column has been directly observed or sampled - The uncertainties and limited amounts of data associated with deep-sea science have important consequences

• Positive data circulation established by Kyushu Smart Fisheries (QSF) team (2024) · Frontiers in Marine Science · cited 3× · doi

  The lack of observation data in coastal and shelf seas. The typical parking depth of 1000 meters of Argo floats does not facilitate routine measurement in coastal and shelf seas. Requesting ocean observations from fishing vessels could dramatically increase the number of in-situ observations in shallow areas.

  data deficiencies exist in coastal regions, - deep-sea observations are sparse and intermittent, - limited measurements of essential ocean variables exist, - the study only analyzed existing data and did not collect new data, - the quality control process rejected 21.97 % of casts

  The study identifies the challenge of limited data availability, particularly in deep-sea measurements and coastal regions. The paper also notes the challenge of resolving the uncertainties in Indonesian Throughflow variability, ocean heat transport, and monsoon forecasting. The study highlights the need for additional deep-sea Argo floats, moored buoys, and gliders within ITF pathways to improve subsurface and deep-sea data coverage.
