U.S. Geological Survey Oceanographic Time-Series Data Collection

Water-level and Wave Measurements from the Chandeleur Islands, Louisiana

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.

* Depths use vertical axis (Z) positive down reference. Sensors located in buried wells or under water have positive sensor depths, but 946, 947 and 951 were mounted in air, so have negative sensor depths.
