Basic Sample Interval

"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.
