Good complete paper!
Section 3. paragraph starting “Gliders are relatively slow…”. I do not understand the solution to the mixed time/space sampling implied in the last sentence, “This problem is a major one, but it can be solved by increasing the number of instruments as sea (point measurements) at the same time, this is the float/glider philosophy.” It is my impression that as with most measurements, we can only rely on the models to correctly perform the time/space interpolation.
P9. “A glider profile can be regarded as vertical.” Given that 1000 m dives can cover 7-10 km, I believe the data assimilation must take into account the x,z sampling, especially the regional and coastal models. The sooner the models/assimilation can be set up to do it correctly, the better, else we will undoubtedly find later that there are inconsistencies and not all the available information in the data is being utilized.
Top of page 10. “The global model would use only two of the collected profiles.” Why would the model not take all of the profiles available to get a better single estimate for the 1 grid point with lower error bars? (actually, it would be best not to pre-process the profiles into one average one – let the data assimilation do that).
P16 – the world tour by steps. Why only “similar” to WOCE lines, and not exactly along these lines (wasn’t this Stommel’s original idea?). This I imagine would help in the interpretation of the repeat sections and contribute to the whole calibration issue. I see no duplication with Argo, given the aliased nature of the float sampling. My recollection was Stommel suggested both routine cross-basin lines (along WOCE or similar) as well as more local, specialized sampling.
Should mention be made of “unconventional” gliders and the roles they may play. I am thinking of the Liquid Robotics surface/subsurface waveglider, and the flying wing glider the Gerald D’Spain at SIO has developed.
Have OSSES been performed? It is my impression that OSSEs have been sorely lacking in all of ocean observing (true, capability has been maturing). OSSEs are essential and belong in the recommendations.

Following my investigation, thousands of people all over the world get the business loans from various creditors. Thence, there is a good possibility to get a sba loan in all countries.

Monday is a very important date, because the topic of Gliders as a component of future observing systems « OceanObs’09 Public Comments was finally brought up. I looked everywhere to find things related to sba loan , and finally I found it! Going to get a cup of Coffee and read on.
