Details on http://www.jcommops.org/DBCP/gts http://www.jcommops.org/DBCP/gts Assistance from myself and CLS (Argos) to share data easily. Data checks: –Metadata and timeliness www.jcommops.org or www.osmc.noaa.govwww.jcommops.org www.osmc.noaa.gov –Data Quality control on http://www.meteo.shom.fr/qctools/ and via monthly statistics http://www.meteo.shom.fr/qctools/

9. 9 Barometer Buoys JCOMM aims to have all buoys in high latitudes measuring Air Pressure Barometer Upgrades (SVPB) offered by drifting buoy manufacturers through financial support by the GDP (AOML) http://www.jcommops.org/dbcp/svpb_upgrade.html

12. 12 Iridium Pilot Project Seeks to evaluate the feasibility of Iridium technology for real-time telecommunication of drifter data –under various conditions e.g. in wide temperature ranges, remote ocean areas and in rough seas, where the buoy will be frequently submerged DBCP funds used to “upgrade” 50 Argos buoys to Iridium ($500 each) to be deployed worldwide, to allow inexpensive access to Iridium Buoys Metocean Iridium Buoy NAL Research 9601 modem

17. 17 Iridium Buoys in the Arctic Météo France and SAMS both deployed Iridium buoys in the Arctic, and found: 1.Iridium drifters didn't report when the temperature was below -35C. SBD modem 9601 doesn't work below this temperature. 2.due to the cold conditions, the batteries drained faster than at mid-latitudes Meteo France Buoy in the Arctic
