Abstract (from http://www.sciencedirect.com/science/article/pii/S0034425716300682): Wetlands are valuable ecosystems for maintaining biodiversity, but are vulnerable to climate change and land conversion. Despite their importance, wetland hydrology is poorly understood as few tools exist to monitor their hydrologic regime at a landscape scale. This is especially true when monitoring hydrologic change at scales below 30 m, the resolution of one Landsat pixel. To address this, we used spectral mixture analysis (SMA) of a time series of Landsat satellite imagery to reconstruct surface-water hydrographs for 750 wetlands in Douglas County, Washington State, USA, from 1984 to 2011. SMA estimates the fractional abundance...
Abstract (from http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0136385): Wetlands are globally important ecosystems that provide critical services for natural communities and human society. Montane wetland ecosystems are expected to be among the most sensitive to changing climate, as their persistence depends on factors directly influenced by climate (e.g. precipitation, snowpack, evaporation). Despite their importance and climate sensitivity, wetlands tend to be understudied due to a lack of tools and data relative to what is available for other ecosystem types. Here, we develop and demonstrate a new method for projecting climate-induced hydrologic changes in montane wetlands. Using observed wetland...

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.

This dataset delineates wetland ponds and emergent wetland vegetation in Mt. Rainier National Park. It was created through object based image analysis of high resolution imagery from 2006 and 2009 and LiDAR data acquired in the fall of 2008. Riparian wetlands are not included in this dataset. Accuracy is only verified for wetland ponds in the subalpine region. Forested wetlands, riparian wetlands, and emergent vegetation were only visually assessed. This data maps all wetland habitat, but was primarily used to locate and delineate amphibian habitat in Mt. Rainier National Park.
