In plain English

What it measures. Seafloor depth measurements gathered by volunteers and everyday vessels rather than dedicated survey ships, pooled into a shared collection.

How it's made. Collected through a crowdsourcing effort run with the International Hydrographic Organization and hosted by NOAA.

How & where you'd use it. Adds depth information in places that lack official surveys, helping fill gaps in seafloor maps.
