measure the
changing seafloor

Seabed 2030 aims to map the whole ocean floor by 2030, and every boat with an echosounder can help. This is a live, open census of each depth sounding shared through the IHO's Crowdsourced Bathymetry initiative and its Data Centre for Digital Bathymetry: counted, deduplicated and mapped, and updated four times a day as NOAA NCEI publishes each batch to the open archive. Browse the raw soundings in the DCDB data viewer.
