data distributed on GTS are therefore consistent with the Argos data collected for the same buoys throughother Argos receiving stations (local or global).b) The new version of the BUOY code was finally implemented at Service Argos on 27 March. Main GTSusers and buoy operators were contacted and encouraged to provide Service Argos with new informationwhich can now be coded in the new format (e.g. buoy type, drogue type, anemometer height).c) GTS buoy data are now delivered to Météo France for global GTS distribution via tcp/ip (instead of X25dedicated link).d) The Argos GTS sub-system reference guide was updated to reflect latest improvements with the system.The new guide was published by the DBCP (Revision 1) and can be obtained from the TechnicalCoordinator of the DBCP.e) Developments are underway at Service Argos for implementation of the BUFR code within the Argos GTSsub-system. BUFR should be available in the beginning of 2003.f) Following discussions by the DBCP evaluation group, updated list of DBCP recommended Argos messageformats is available from the DBCP web site at: http://www.dbcp.noaa.gov/dbcp/1ramf.htmlo Metadata/Manufacturer's spec. sheet.Discussion is underway on specifications sheet for manufacturers to fill in upon buoy purchase. This would facilitatecollection and access to metadata. The matter was particularly discussed between the EGOS Technical Secretary,Anne Hageberg, and the Technical Coordinator of the DBCP, Etienne Charpentier. Things have been clarified tosome extend although work is still required to eventually agree on (i) what metadata are needed, (ii) which metadataare mandatory and which are optional, (iii) what are the metadata that need to be provided by the manufacturer andwhat are those which need to be provided by the buoy operator, (iv) how the metadata should be provided (structureof spec. sheet), (v) who should eventually make necessary developments, and (vi) who should fund suchdevelopments.o New Lagrangian drifter design.The Global Drifter Programme is in the process of redesigning the SVP drifter, including the SVPB by reducing itssize in order to lower the cost and therefore increase the number of buoys deployed worldwide at constant budget.While keeping a drag area ratio of about 40, new design will be cheaper, smaller in size (2/3 of original size), droguediameter will be 60cm, drogue will be 6m long and include 4 sections. 7.5V and 0.5W Toyocom Argos transmitterswill be used. Cost is expected to be in the order of $1700 per unit (i.e. standard SST drifter) instead of $2200 at themoment. 50% of the drifters purchased in 2002 should have new design.o DBCP web site.DBCP web site moved. New URL is now http://www.dbcp.noaa.gov/o JCOMMOPS.Following support by the DBCP (DBCP-16) and by SOOP which provide most of JCOMMOPS resources, JCOMMin situ Observing Platform Support Center (JCOMMOPS) concept was discussed and strongly endorsed at the firstJCOMM meeting, Akureyri, Iceland, 19-29 June 2001. See description of JCOMMOPS athttp://www.jcommops.org/doc/jcommops/jcommops.htm.o Safety.Following explosion in august 2001 of a moored data buoy during maintenance onboard a ship in the Bay of Bengalwhich resulted in the death of a crew member, the Indian National Institute for Ocean Technology (NIOT) whooperated the buoy constituted an expert committee to examine the incident. This committee had concluded that the30
explosion was due to the emission of hydrogen and oxygen from overcharged batteries, ignited by an electricalspark. The recommendations of the expert committee were then placed before the Data Buoy Cooperation Panel andthe issue was discussed further with the buoy operator, Panel Members, and manufacturers at its 17th session. Afterdiscussion, the panel recommended that manufacturers should enhance buoy safety through improved design in thefollowing areas:• Batteries are to be placed in a vented compartment, eliminating voids as far as possible, with adouble venting arrangement;• Incorporation of an overcharge controller and temperature controlled switch, to disconnect thebatteries from the solar panels when required;• Incorporation of an explosive gas sensor and temperature sensor inside the battery compartment andinstrument cylinder, with the data to be transmitted once a day, to allow corrective action, or suitableexplosive gas testing procedures, to be undertaken on buoy retrieval or servicing;• Incorporation of continuous monitoring of battery charge current and voltage, to be transmittedwith the buoy data;• Incorporation of a suitable purging system and procedures.Buoy operators and manufactuers are urged to take above information into account. A dedicated web page isavailable at http://www.dbcp.noaa.gov/dbcp/safety.htmlo DBCP evaluation group.The terms of references of the SVPB/SVPBW evaluation group had been extended to include other types of buoyand to work on other issues such as Argos message format etc. Sub-group works mainly through mail exchange anduse the DBCP technical forum (http://forum.jcommops.org/) for basic open discussion, record of those discussionsand publication of intermediary or final results. Sub-group presently includes the following people: ElizabethHorton, Navoceano (Chairperson), Pierre Blouch, Météo France, Sarah North, UKMO, Graeme Brough, BOM,Peter Niiler, SIO, Etienne Charpentier, DBCP, Tony Chedrawy, Metocean, Jeff Wingenroth, Technocean, GaryWilliams, Clearwater Instrumentation, Sergey Mothyzev, MARLIN, Louis Vermaak, SAWB, Ron McLaren,Environment Canada, Julie Fletcher, MSNZ, New Zealand, and Satheesh Shenoi, NIO, India. Any other personinterested in participating in the evaluation group should contact Elizabeth Horton.o DBCP definitions.Following recommendations by the DBCP at its 17 th session in Perth, the DBCP evaluation group proposed a set of"DBCP Definitions". These included definitions of specific DBCP ocean areas. For example DBA area is defined asthe Atlantic Ocean between Arctic Circle and 55S and for southern latitudes between 65W (Drake passage) and 20E(Cape of Good Hope). It includes Norwegian Sea, Labrador Sea, North Sea, and excludes Gulf of Mexico,Caribbean Sea, Hudson Bay, Baffin Bay, Mediterranean Sea, Baltic Sea. NDNA area is defined as DBA North ofTropic of Cancer. Other definitions which are for DBCP use only, include for example resolution (time, horizontal,vertical), useful observation, useful day of observation, early failure/infant failure, required variables, operationaland useful life-time, delay, data availability. Details on DBCP definitions can be found on the JCOMMOPS forumunder DBCP at http://forum.jcommops.org/31
