The results of Argo-Italy: floats, drifters and gliders in the Mediterranean Pierre-Marie Poulain OGS, Trieste, Italy Argo-Italy Program Outline Observations collected in the Mediterranean in 2012-2013 with: Surface drifters Gliders Profiling floats Plans for 2013-2014
Argo-Italy Program Italian contribution ti to the global l ocean observing system: with specific focus to the Mediterranean, the Black Sea and the Southern Seas (Antarctic) by means of Argo floats (EuroArgo) Surface drifters (GDP) Gliders (EGO) Ships of opportunity (SOP) sponsored by MUIR since 2011 (0.5 ->1 M / year)

Surface Drifters: SVP Designs Drifter observations Low-cost (1-2 K ) & generally expendable Tracking and data telemetry (GPS and Iridium) Data: Near surface currents (0, 15 m) from hourly successive positions SST Near real time (NRT) data processing and dissemination (1-h sampling period) Cost (1-2 K ), expendable

Glider observations 1) Gliders are driven by positive and negative buoyancy created by a change in volume. No propeller is required. 2) Wings convert vertical velocity into forward velocity. 3) To change the direction of the glider a rudder is used or internal mass is rotated. 4) Glider move downward and upward in a sawtooth pattern Autonomous Gliding Vehicles Seaglider APL-University of Washington Slocum Webb Research Corp. Spray Scripps Institution of Oceanography
Glider observations Glider sensors Argos, Iridium, VHF link Relative high cost (100-150 K ) Not expendable! NRT data (every surfacing): O 2 Pressure, temperature, conductivity (salinity) Oxygen, chlorophyll, turbidity, etc. Pinger Optics Sea-Bird CTD
