No gliders are exclusively on the sea surface, if by 'glider' we mean a system that uses buoyancy to initiate forward motion. They are all able to operate within the water column. So I might say</div><div>3C: A platform with buoyancy-based propulsion that routinely surfaces to meet its objectives. </div><div>27: A platform with buoyancy-based propulsion that can routinely meet its mission objectives without surfacing.</div><div>These are then mutually exclusive.</div><div><br></div><div>49: The term 'undrogued' is unfamiliar to me, and to my 3 buddies with ocean background. Looking it up seems to product multiple definitions. Any chance we could be more specific?

I assume we don't mean of the _entire_ sea surface, but we don't mean of the sea surface within 1 meter, either. </div><div><br></div><div>John</div><div><br></div><div><br></div><div><br><div><br></div><div><br><div><div>On Aug 1, 2013, at 05:49, "Lowry, Roy K." <<a href="mailto:rkl@bodc.ac.uk">rkl@bodc.ac.uk</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div style="font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><font face="Calibri, sans-serif" size="2"><div>Dear All,</div><div> </div><div>Discussions on this have gone quiet, so I'll summarise what has been said into a proposal for change:</div><div> </div><div>New codes:</div><div> </div><div>CODE: 3C</div><div>Preferred Label: surface gliders</div><div>Definition: A platform with buoyancy-based propulsion that is confined to operation on the sea surface.</div><div>Mapping: broadMatch to surface autonomous vehicle</div><div> </div><div>CODE: 27</div><div>Preferred Label: sub-surface gliders</div><div>Definition: A platform with buoyancy-based propulsion that is able to operate within the water column.</div><div>Mapping: broadMatch to autonomous underwater vehicle</div><div> </div><div>CODE: 49</div><div>Preferred Label: surface ice buoy</div><div>Definition: An undrogued surface float that is deployed in regions where sea ice forms that moves with either ice or water depending upon the time of year.</div><div>Mapping: broadMatch drifting surface float</div><div> </div><div>CODE: 93</div><div>Preferred Label: pack ice</div><div>Definition: Sea ice not connected to land covering over 70% of the sea surface.</div><div>Mapping: broadMatch cryosphere</div><div> </div><div>CODE: 94</div><div>Preferred Label: drift ice</div><div>Definition: Sea ice not connected to land covering under 70% of the sea surface.</div><div>Mapping: broadMatch cryosphere</div><div> </div><div>If there are no further comments I'll add these records to the vocabulary when I return from leave on August 20<font size="1"><sup>th</sup></font>.</div><div> </div><div>Cheers, Roy.</div><div> </div><div> </div><div> </div><div>Please note that I now work part-time from Tuesday to Thursday.
