I was looking at some glider datasets from OOINet today (including PG575 and GL340), and it looks like the calculated depths are 1/10 of what they should be. This is the case both on the website and in the downloaded netcdf files.
My guess is the calculation is using bar (sci_water_pressure) instead of dbar (sci_water_pressure_dbar).
Thank you for bringing this to our attention. I am seeing the same issue with the data and have brought it to the attention of the development team. I will update this thread once a fix is in place.
