Baliles Center (Hull Springs) Aimes Creek water depth data from 2021-05-04 to 2021-10-30

General Metadata for Hull Springs Dock-YSI Sampling Station

Files

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

HS_YSI_YYYY-MM-DD_metadata.txt
HS_dock_pressure_trans_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.

Description

These data are from the sampling station in Aimes Creek on the Camp House dock (38.125367, -76.659537).

* Physical and chemical water data are collected with a YSI EXO2 sonde.

* Temperature (dC) and Pressure (KPa) are collected with an Onset HOBO U20-001-01-Ti Water Level Logger

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

Station Specifics

The sensors are sampled every 15 minutes
