Final report, Mapping wetland hydrology across an ecoregion and developing climate adaptation recommendations
Depressional wetlands in the Columbia Plateau are valuable habitats because they maintain surface water into or throughout the dry summers. The source of that moisture—surface runoff from surrounding areas, or groundwater in local aquifers—may determine if these wetlands are seasonal, permanent, or semi-permanent. Helping these wetlands continue to provide habitat and other services requires understanding how these flooding and drying patterns (their hydrology) have changed in the past, and how projected changes in climate might affect them. The goal of this project was to develop wall-to-wall maps of wetlands across the region, coupled with detailed 30-year hydrographs of historical (1984-2014) fluctuations in...
Geomorphic approach to global classification for natural inland wetlands and rationalization of the system used by the Ramsar Convention - A discussion
Use of satellite radar imagery for monitoring flood conditions in wetland ecoystems of southern Florida
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)
Modeling Climate Impacts on the Hydrology of Pacific Northwest Montane Wetland Ecosystems - Final Report
Wetlands are globally important ecosystems that provide critical services for natural communities and human society, such as water storage and filtration, wildlife habitat, agriculture, recreation, nutrient cycling, and carbon sequestration. They are also considered to be among the most sensitive ecosystems to climate change, which will exacerbate the already threatened nature of wetlands due to changes in land-use. In montane regions, wetlands are expected to be particularly susceptible to climate-induced changes, but tools to assess the impacts of climate change are severely limited relative to other ecosystem types. To address the need for quantitative assessment tools we developed projections of climate-induced...
Distribution of diatoms among intermittent ponds on the Atlantic Coastal Plain: development of a model to predict drought periodicity from surface-sediment assemblages
Functional analysis and restoration of Mediterranean lagunas in the Mancha Humeda Biosphere Reserve (Central Spain)
Seasonal median daily water depths for study wetlands in the Tamarac National Wildlife Refuge, the St. Croix National Scenic Riverway, the North Temperate Lakes Long-term Ecological Research area, and the Upper Mississippi River study area from 2013-2018
To relate water levels in these individual wetlands to precipitation and amphibian calling activity
Seasonal median daily water depths for study wetlands in the Tamarac National Wildlife Refuge, the St. Croix National Scenic Riverway, the North Temperate Lakes Long-term Research area, and the Upper Mississippi River study area from 2008-2012
To relate water levels in our study wetlands to temperature, precipitation, wetland water depth, and amphibian calling activity, we installed one pressure logger in the deepest spot we could find in each wetland. Soon after thawing conditions allowed, we drove a plastic pipe (anchor pipe) into the sediments at the deepest location and secured another pipe to it that contained one pressure logger (Global Water Model 14 and 15 [College Station, TX, USA] or Onset Computer Corporation Model U20-001-04 [Bourne, MA, USA]) suspended approximately 2.5 cm above the sediments. We installed additional individual pressure loggers in the upper part of the logger pipes (in air) at select locations to measure barometric pressure...

Wetland surface water dynamics in the channeled scablands of Washington State reconstructed from a time series of Landsat satellite imagery, 1983–2011
This dataset provides point locations of wetlands in the channeled scablands of Washington State. It was created through object based image analysis of high resolution imagery from 2006 and 2009. Each wetland location has an associated surface water hydrograph constructed from spectral mixture analysis of Landsat satellite imagery (1983 – 2011). Hydrologic data is stored in an associated csv file and can be linked to the data through a unique identifier (Wetland_ID). Additionally, individual surface water hydrographs for wetlands, in jpeg format, can be linked to wetland location through the unique identifier.
