"Basic Sample Interval" means the time interval at which the data were collected, thus the files served here have different time bases. Some files will contain data sampled every 5 minutes, while others contain data sampled every 60 minutes. The basic sample interval varies by instrument and deployment. The basic sample interval is listed in each file's global attributes as "DELTA_T" (in seconds). In the table, positive Latitude or Longitude indicates North or East.

* Depths use Z positive down reference. Most sensors were located in buried wells on the beach so have water depth of zero and positive sensor depths. 9651hwl-a.nc was in air, 4 m above the surface, so that sensor depth is negative.
