"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 under water so have positive sensor and water depths. Instruments at site 952 were in air on or above the marsh surface, so water depth is zero and sensor depths are negative.
