Ocean AND Coastal Observation Systems

Data Buoy – Ocean Observation systems Since 1997, Varya has been the only company in India involved in the end-to-end integration, deployment, management and retrieval of moored data buoy-systems in India’s coastal and deep-sea regions. Varya offers a complete range of Data Collecting Systems for measuring Ocean and atmospheric Parameters.

Varya offers a range of products for measuring Ocean and atmospheric parameters. Varya Buoys can accommodate a wide selection of sensors customised to the customers requirement. Varya data buoys are designed to withstand harsh environments while maintaining excellent stability. The rugged, corrosion-proof buoys can be used for multiple measurements in extreme oceanographic conditions.
