Success Stories

Our products are used worldwide by amazing people and organizations to collect data, create ocean awareness, and build ocean industries.

The Sofar Spotter buoy is an ideal rapid response data observation platform. Within hours of a storm alert, the Brazilian Navy was able to deploy a Spotter buoy off the coast of Rio de Janeiro to capture in situ wave and weather data.

The purchase and operating cost of the Spotter is much lower than the large buoy so we are now using it as our primary offshore wave data source and have purchased a second spotter to allow them to be regularly swapped over while moorings are checked and biofouling removed.

The Brazilian Navy chose Sofar Spotters to support their weather research and monitoring mission in the Southern Ocean.

The University of Tokyo chose Sofar Spotters to conduct studies at high latitudes to better understand the nature of sea-ice interaction. The Spotter buoys were both resilient and able to provide meaningful data to the team even after spending the winter in the harsh Arctic Ocean.
