"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 and East.

* Depths use Z positive down reference. Sensors that were underwater have positive sensor depths. The Hobo Pressure Loggers that were in air, have negative sensor depth.
