8. Data Dissemination: Yearly by instrument Geographically by instrument WODselect All updated quarterly Format: Native WOD format (compact ASCII) with conversion routines netCDF -> feeds into NODC Geoportal/THREDDS server Working now on subset dissemination through Geoportal

9. WODselect download page -For ASCII format, choice of two flags: default is originators flag + WOD flag. -For netCDF format, no restriction on number, form of flags -Can also bundle entire IQuOD QC’ed dataset. -First, only temperature flags (include WOD flags for other variables?) -Not all data IQuOD QC’ed (include automatic IQuoD flags for other temperature data?)
