A deep-diving underwater glider is set to begin an epic 73,000km five-year journey circumnavigating the entire globe to collect data to improve weather forecasting.

The pioneering world-first tech will launch from the edge of the continental shelf, south of Martha's Vineyard, Massachusetts, on Oct. 10.

The glider will dive to depths of 1,000 meters and surface every eight to 12 hours and use satellites - sharing vital data on ocean temperature, salinity, currents, and ocean health.

This data will help refine weather models and improve hurricane intensity forecasting. The data will also help to inform ocean policy and conservation efforts.
