IHO Data Centre for Digital Bathymetry (DCDB)

The IHO Data Centre for Digital Bathymetry (DCDB), hosted by NOAA's NCEI on behalf of the International Hydrographic Organization, archives crowdsourced and other contributed ship depth soundings, downloadable via a map viewer and NOAA's open-data cloud bucket. The NCEI page says: "The Centre archives and shares, freely and without restrictions, depth data contributed by mariners and other stakeholders consistent with IHO direction and guidance."
