One of the great obstacles for accurate climate modeling of the ocean environment is a lack of direct data measurements. Sofar Ocean was founded to address this deficit by designing and manufacturing Spotter, a small-scale weather buoy that collects data in the far reaches of the open ocean. Sofar uses this pin-pointed data to power an ocean weather forecasting model that is up to 50% more accurate than NOAA for short-range forecasts. Applying this data to practical use we built Wayfinder, a route optimization tool for shipping companies that turns weather insights into dynamic routing guidance for shipping vessels, updating and rerouting them as new weather systems emerge. Greater efficiency saves fuel and money, with our ultimate goal being to decrease the carbon output of shipping companies, some of the biggest contributors to global carbon emissions.
