the Sippican deck unit as it downloads temperature versus depth. I also know for certain that the modified equations have been applied by recalibration post-processing. However, I don't know whether anybody has updated the deck unit firmware (which would be
fairly easy as the difference is just coefficient values) to use the updated equations.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Calibri","sans-serif"">An issue is arising with a request to add a set of additional XBT entries to the SeaVoX instrument vocabulary (L22). In most cases, this includes two entries for certain
physical types of XBT (e.g. Sippican T5) with the entries differentiated by the fall-rate equation applied (Sippican or GOOS). I'm a little uneasy about this as to me it could be viewed as shoe-horning information that isn't actually instrument type into the
instrument description. However, I am also aware of instruments that have multiple designations and all that's different between the variants is the firmware.<o:p></o:p></span></p>
