High-frequency sensor data from a YSI 600 OMS (Optical Monitoring System) (every 15 minutes) in a meadow reach at White Clay Creek from January 2019 through February 2021. Funded by NSF and DEB as part of the LTREB grant to study the recovery of stream ecosystem structure and function during reforestation, Stroud Water Research Center. The parameter in this data package is turbidity. Data is presented in two tables which likely have significant overlap. The raw data table presents the data exactly as it was downloaded from the Aquarius Database. It is formatted as a "wide" human-readable table. Turbidity at White Clay Creek Site WCD1139 since 2019 YSI presents only the data from the respective sensors. These tables are gap filled for intervals greater than 30 minutes and less than 24 hours. It is formatted as a "wide" human-readable table. All of the parameters and table are further explained in the metadata.
