<DIV>Hi John,</DIV>
<DIV><FONT face=tahoma></FONT> </DIV>
<DIV><FONT face=tahoma>I think we're on different wavelengths regarding the
gliders. What I'm trying to distinguish - following your initial
suggestion - are gliders whose spatio-temporal feature type may be reasonably
be considered a 2D trajectory (i.e. having a single nominal depth in
metadata works) from those where the feature type needs to be a 3D
trajectory (i.e. the data make no sense without a depth co-ordinate
variable). You obviously didn't get this from my definitions. The
need to surface didn't come into it. If I replace 'within the water column'
by 'at variable depths significantly below the surface' does that make it
clearer?</FONT></DIV>
<DIV><FONT face=tahoma></FONT> </DIV>
<DIV><FONT face=tahoma>A drogue is an underwater parachute attached at a depth
of around 40m to surface drifting buoys to encourage them to follow the
motion of the water rather than the surface winds. I considered this to be
a well-known term - it's certainly well used by people I know. Admittedly
'undrogued' is an adaptation of the word that won't be found in the Oxford
English Dictionary, but it is creeping into common usage in the operational
oceanography community. According to JCOMMOPS it is critical to the
definition. I'll clarify by adding '(no underwater parachute)' unless
anybody else objects.</FONT></DIV>
<DIV><FONT face=tahoma></FONT> </DIV>
<DIV><FONT face=tahoma>I inherited the sea ice definitions (via Mathieu at
JCOMMOPS) from </FONT><FONT face=Arial>The Canadian Ice Service of Environment
Canada, but rephrased them slightly - possibly not very well. Can anybody
provide me with improved wording?</FONT></DIV>

<DIV>A few thoughts.
<DIV><BR></DIV>
<DIV>3C and 27 are difficult to distinguish. 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? Or perhaps it isn't critical to the
definition?</DIV>
<DIV><BR></DIV>
<DIV>93/94: 'covering over/under 70% of the sea surface' -- at what scale is
this metric assessed? 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>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>
