Profiling floats report a number of times while on the surface in order to relay the full profile to a shore station. Each message is time stamped and may or may not have a position determination. All of the surface positions of the floats are included in the surface drift data files here. Each has a time attached, but if a position was not available, the position remains empty. On other locations, the position may be known but the time is not. Again the time field is empty.

Inventory records have not been constructed from these data because there has been no consistent quality control applied. Users will find unusual and wrong values in both profiles, locations and times. It was not possible to consistently edit out these values to produce inventory records that would be useful.The profile files contain only those data for which there is at least one profile (temperature or salinity). Some of the surface drift information provided here, may duplicate what has been compiled by the Float DAC. Users are cautioned to consider possible duplications if data from the Float DAC is combined with the data provided here. Since the data in this collection have undergone unknown QC procedures, users should find the data from the Float DAC to be of higher quality.
