Format

A tibble with 10,883 rows and 4 columns:

datetime

POSIXct. Date and time in UTC (original timezone: MDT, UTC-6).

sonde

Character. Sensor identifier. "REZN" was deployed 8/23/2012 through 9/1/2012 12:50 MDT; "TOWN" from 9/1/2012 12:55 MDT through 9/30/2012. Approximately 15% of rows have NA in temp_C and DO_mgL.

temp_C

Numeric. Water temperature in degrees Celsius. Some anomalous negative values are present in the raw data and have not been filtered.

DO_mgL

Numeric. Dissolved oxygen concentration in mg/L.
