This USGS Data Release represents geospatial and tabular data for a study investigating linkages between local terrain and wetland hydroperiod and was supported by the U.S. Geological Survey (USGS) Amphibian Research and Monitoring Initiative (ARMI). This dataset contains wetland water level data from Saint Marks National Wildlife Refuge (SMNWR). Data include records of water level and water temperature measurements from select wetlands beginning in July 2010 and ending in 2019. Not all wetlands span this entire period as different phases of studies resulted in different time periods of data collection. Instrumentation included a staff gage and a non-vented continuous logging pressure transducer that logged data at 1-hour intervals. The dataset consists of 4 separate items: 1. water level monitoring site Locations (tabular data) 2. wetland perimeters (GIS vector data) 3. water level and water temperature data for 59 select wetlands (tabular data) 4. revision history text file that describes the changes from the original release to version 2.0. In Version 2.0 of this data release, data collected since the initial publication (2016) are being added to the data release to provide a longer record. Additionally, wetland perimeters (polygons) that were not available during the first release are added to version 2.0.

This dataset includes hydrological measurements of 300 US temporary wetlands from 2004-2014.

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).

This USGS Data Release represents geospatial and tabular data for a study investigating linkages between local terrain and wetland hydroperiod. The data release was produced in compliance with the new 'open data' requirements as way to make the scientific products associated with USGS research efforts and publications available to the public. The dataset consists of 3 separate items: 1. water level monitoring site Locations (tabular data) 2. surveyed wetland perimeters (GIS vector data) 3. water level and water temperature data for 58 select wetlands (tabular data)

This dataset contains the approximate location of 59 wetlands that were monitored as part of the U.S. Geological Survey (USGS) Amphibian Research and Monitoring Initiative (ARMI). Note, these were preliminary points used for locating the wetlands in the field and they may not fall directly within a wetlands boundary. The later surveying of pond boundaries provides more accurate locations. These point locations were collected with a Garmin GPSmap62 unit.

The Northeast Temperate Network (NETN) monitors water quality and water quantity at 9 national park sites to document the status and trends of their lake, pond, and stream resources. NPS scientists have collected standardized measurements of stream discharge, stream and lake stage, water transparency, in situ water quality (temperature, dissolved oxygen, pH, etc), and other measurements from May to October every year beginning in 2006. Water samples were also collected each year to measure nitrogen and phosphorus to assess potential nutrient enrichment. This data package contains a cumulative record of all water monitoring data collected at NPS IMD NETN park units through the most recent field season and is organized into twelve (12) datasets: Chemistry_Data_Long_YYYYMMDD.csv – water sample chemistry and nutrient data (e.g., TN, TP, ANC, Chl-a). Long format. Chemistry_Data_Wide_YYYYMMDD.csv – water sample chemistry and nutrient data (e.g., TN, TP, ANC, Chl-a). Wide format. Discharge_Data_YYYYMMDD.csv – stream flow data collected by a current meter. Event_Info_YYYYMMDD.csv – sampling event-level data (e.g., date, observer, meteorological conditions, etc.) Light_Penetration_Data_YYYYMMDD.csv – profiles of photosynthetically active radiation collected by a light meter. Secchi_Data_YYYYMMDD.csv – Secchi disk depth data. Sites_Lake_YYYYMMDD.csv – precise location data and descriptive information for NETN lake sites. Sites_Stream_YYYYMMDD.csv – precise location data and descriptive information for NETN stream sites. Sonde_InSitu_Data_YYYYMMDD.csv – profiles of in situ multiparameter sonde measurement data (e.g., specific conductance, pH, DO, etc.). StageDatum_Info_YYYYMMDD.csv – information on water level benchmarks (e.g., elevation, datum type, etc.). StreamSite_Observations_YYYYMMDD.csv – specific observations about water appearance (e.g., color, algae type, etc.). WaterLevel_Data_YYYYMMDD.csv – water surface heights relative to established benchmarks, including partial and continuous gage station elevation records.
