Baliles Center (Hull Springs) Wetland Data 2021-10-28 to 2021-12-04

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_Depth_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.

File Modified

• 2021-07-22 by KF - added general metadata for the pressure transducer and the CT sensor.
• 2021-11-10 by KF - updated to include the depth calculations from the water level logger.

Description

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

Station Specifics

The specific at each site are:

* Water Temperature (dC) and Dissolved Oxygen (mg/l) are collected with a Onset HOBO U26-001 Dissolved Oxygen Logger
* Water Temperature (dC) and Water Pressure (mmHg) are collected with an Onset HOBO U20-001-01 Water Level Logger
* Water Temperature (dC) and Conductivity are collected with an Onset HOBO U24-001 Conductivity Logger
* Air Temperature (dC) and Barometric Pressure (mmHg) are collected with an Onset HOBO U20-001-01 Water Level Logger mounted in the air next to the wetland.

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)
* observation.DO, .CT, .press, or .BP - the incremental number of each observation from the DO,      conductivity, water pressure, or barometric pressure sensor.
* timestamp.DO, .CT, .press, or .BP - the data and time that the record was collected, as reported   by the data logger (MM/DD/YY HH:MM:SS A/PM) from the DO, conductivity, water pressure, or barometric     pressure sensor.
* DO - the concentration of dissolved oxygen in the water (mg/L)
* Temp.DO, .CT, .press, or .BP - the temperature (dC) from the DO, conductivity, water pressure, or  barometric pressure sensor.
* Pressure.press or .BP - the pressure recorded by the pressure transducer (kPa) on the water        pressure or barometric pressure sensor.
* Z - the depth of the water (cm).
* 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)
* press.g.cm2 - the pressure from the water pressure sensor (g/cm^2)
* BP.g.cm2 - the barometric pressure from the barometric pressure sensor (g/cm^2)
