NEMO-Float
OPTIMARE has developed the Navigating European Marine Observer (NEMO)-Float for the research programme ARGO (www.argo.ucsd.edu). NEMO has been further developed on the basis of the SOLO-Float. NEMO ascends from a depth of up to 2000 meters in regular intervals to the surface and transmits the collected data via the ARGOS satellite system. The NEMO-Float has been further improved to allow the deployment under ice, positioning through GPS and RAFOS, as well as the integration of new sensors and telemetries.
PopUp-Buoys
Recovery of oceanographic data from moored sensors normally requires operation of large research vessels. PopUp-buoys serve as data capsules; they can receive and store data from moored sensors via wireless IrDA data transfer. After a given time or a specific command, the PopUps are individually released from the sensor-PopUp array to ascend to the sea surface from where data are transferred via Iridium communication to a receiving station.
