Ocean Networks Canada’s video archive and annotation tool, [SeaTube](https://data.oceannetworks.ca/ExpeditionManagement), is helping drive a collaborative global understanding of subsea maritime cultural heritage, including rare glimpses at underwater archaeological sites from the Second World War. In partnership with the National Oceanic and Atmospheric Administration (NOAA) and Ocean Exploration Trust (OET), 73 hours of visual surveys of historic shipwrecks from the Battle of Midway in the Central Pacific Ocean are now available on SeaTube. The platform’s built-in features enables the public to see the deep sea sites, and for the international scientific community to collaboratively annotate these important historical records.
