SEAS 2000 developments during last two years  Automated Met Observations, operational within the NOAA fleet.  Automatic re-drops on failed drops in HD mode.  Migration from DOS system to Windows in LD.  Automated production of monthly, semestrial and annual reports.  Automated detection of problems with the transmission of data into the GTS.  TSG transmission (SBE21, SBE45) and external temperature sensor via Iridium (being implemented).  XBT transmission transition from Inmarsat to Iridium (in its very early stages).  pCO2 system, fluorometry and oxygen transmission (under development).  Seas 2000, autolauncher and HD set up manuals.

SEAS 2000 plans  TSG  Inmarsat to Iridium migration, reducing significantly the transmission cost of each XBT profile, from approximately $15 to $1.5 per profile.  BUFR and Metadata.

 Recruiting: AX08 and PX08 transects  GTS: Some (very few) SEAS data still not inserted into GTS  Is each of the currently maintained lines really needed ?  Can profiling float observations really reproduce signals detected in LD transects ?  Do we need to restore any of the dropped LD XBT lines ?  Do we need additional LD/FRX/HD lines ?  Update, in coordination with scientific community, the national, regional and international requirements (e.g, CLIVAR-Indian Ocean recommendations recently updated).  Use of T-5 (~2000m deep).  Fall rate equation.  Coordinate bulk purchases of XBTs among institutions.
