EvoLogics GmbH supplied Arkona, one of the Germany operated MARNET’s monitoring stations, with a reliable wireless solution to retrieve data from the Acoustic Doppler Current Profiler (ADCP), a seafloor instrument acquiring information for regular national and international assessments of the Baltic Sea state.

Autonomous Arkona station, operated on behalf of BSH by the Leibniz Institute for Baltic Sea Research Warnemuende (IOW), is located in highly-stratified shallow waters, an extremely harsh environment for subsea acoustic communication.

EvoLogics GmbH was challenged to provide reliable instant transmissions of the ADCP’s hourly measurement results and to monitor the seafloor instrument’s battery status, minimizing overall energy consumption. EvoLogics S2C R 48/78 acoustic modem units were installed, each equipped with an internal data-logger to prevent data loss and conserve energy when unable to transmit or receive data under unfavorable conditions of the acoustic channel.

Based on the patented S2C (Sweep-Spread Carrier) technology, EvoLogics S2C R acoustic modems have been deployed at the Arkona station for more than 6 months. Over this period, the data transmission was proven reliable and efficient – no data was lost, while only 30 per cent of the seafloor unit’s battery capacity was consumed by its components. EvoLogics S2C R acoustic modems will continue operating at the Arkona station for another 6 months or more.

EvoLogics GmbH is a high-tech enterprise, specializing in underwater acoustic communications, acoustic positioning equipment and innovative solutions for robotics.

The Federal Maritime and Hydrographic Agency of Germany (Bundesamt für Seeschifffahrt und Hydrographie, BSH) is Germany's central provider of maritime services to industry, science and environmental organisations.

The Leibniz Institute for Baltic Sea Research (Leibniz-Institut für Ostseeforschung Warnemünde, IOW) is a prominent German marine research facility, focusing on the ecosystem of the Baltic Sea.
