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: <pre><code>HS_wetland_DO_YYYY-MM-DD_metadata.txt HS_wetland_Depth_YYYY-MM-DD_metadata.txt HS_wetland_CT_YYYY-MM-DD_metadata.txt</code></pre> 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 Created 2021-06-16 by KF 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).
