Water level and water temperature data from select depressional wetlands at Saint Marks National Wildlife Refuge: July 2010 - May 2019 (Version 2.0, August 2022)

Metadata Updated: July 6, 2024

This dataset contains records of water level and water temperature measurements from select wetlands at Saint Marks National Wildlife Refuge. These data were collected as part of the U.S. Geological Survey (USGS) Amphibian Research and Monitoring Initiative (ARMI). Beginning in July 2010, hydrologic monitoring equipment was installed in 24 wetlands. Instrumentation included a staff gage and a non-vented continuous logging pressure transducer (Onset Comp U20) that logged data at 1-hour intervals. An additional 35 sites were instrumented in January 2014. Data for individual wetlands covers different time periods based on different phases of studies and sensor battery failures. In shallow, ephemeral wetlands these instruments were installed in the deepest point in the basin. In permanent wetlands, instruments were positioned as deeply as possible in proximity to vegetative indicators of permanent water (e.g. Nuphar, Cephalanthus). Additionally, an Onset Comp U20 sensor was deployed sub-aerially to correct water levels for atmospheric pressure. Sites were visited approximately quarterly to read staff gages and download data from transducers. Staff gages were read to the nearest hundredth of a foot. Data were adjusted based on the periodic staff gage readings and barometric pressure readings using features in the software HOBOware (Onset Corporation). The mention of firm, product, or trade names is done so for informative purposes only and does not constitute and recommendation or endorsement by the federal government.
