Hull Springs Wetland Dissolved Oxygen and Water Temperature Data from 2021-05-04 to 2021-06-11

# General Metadata for Hull Springs Restored Wetland Sampling Station

## Files

Specific metadata for each deployment and sensor can be found as text files with the file format of:

    HS_wetland_DO_YYYY-MM-DD_metadata.txt
    HS_wetland_pressure_trans_YYYY-MM-DD_metadata.txt
    HS_wetland_CT_YYYY-MM-DD_metadata.txt
    
Where YYYY-MM-DD is the date that the sampling period ended.

NOTE: The metadata in the above file is collected from the data logger and does not have all of fields present in the final data set, because some were created during data cleaning. Details on how the data were cleaned and variables created can be found at in the cleaning scripts on Gitlab [https://gitlab.com/leo147/leo/-/tree/master/lab_notebook/data_processing/cleaning_scripts](https://gitlab.com/leo147/leo/-/tree/master/lab_notebook/data_processing/cleaning_scripts).

## File Modified

  * 2021-07-22 by KF - added general metadata for the pressure transducer and the CT sensor.

## Description

These data are from the sampling station in the restored wetland at Hull Springs. The sensors are in the NE corner of the shallow pond portion of the restored wetland (38.119289, -76.667252).

All data are CC-BY and should be cited using the DOI available at https://zenodo.org/communities/leo/

## Station Specifics

  The specific at each site are:

    * Temperature (dC) and Dissolved Oxygen (mg/l) are collected with a Onset HOBO U26-001 Dissolved Oxygen Logger
    * Temperature (dC) and Pressure (mmHg) are collected with an Onset HOBO U20-001-01 Water Level Logger
    * Temperature (dC) and Conductivity are collected with an Onset HOBO U24-001 Conductivity Logger

The sensors are sampled every 15 minutes
 
## Measurement Parameters, units, and Variable Names

    * date.time - the date and time that the record was collected, reported in POSIX standard time (YYYY-MM-DD HH:MM:SS)
    * date.time.adj - the date and time of the pressure measurement that was adjusted to match the barometric pressure measurement from the weather station.
    * observation - the incremental number of each observation
    * timestamp - the data and time that the record was collected, as reported by the data logger (MM/DD/YY HH:MM:SS A/PM)
    * DO - the concentration of dissolved oxygen in the water (mg/L)
    * Temp - the temperature of the water (dC)
    * Pressure - the pressure recorded by the underwater pressure transducer (mmHg)
    * Low_Range_CT - the conductivity read from 0 - 2500 uS/cm (uS/cm)
    * Full_Range_CT - the conductivity read from 0 - 15000 uS/cm (mmHg)
