Arnold, William A2017-03-072017-03-072017-03-07https://hdl.handle.net/11299/184899Surface water samples were collected from seven prairie pothole wetlands between 2012-July and 2014-November. Optical and photochemical parameters of the samples were measured under controlled laboratory conditions. The data were collected to better understand the way in which seasonal changes and spatial differences in prairie wetland water chemistry influence photochemistry. Samples are identified by the month and year in which they were collected and the typical hydroperiod of the wetland surface water (temporary or semi-permanent). Rates of formation, steady-state concentrations, and apparent quantum yields (or appropriate proxies) were measured for triplet excited states of dissolved organic matter, singlet oxygen, hydroxyl radical, and carbonate radical under a broadband xenon-arc lamp with a 290-nm wavelength filter.Attribution 3.0 United Stateshttps://creativecommons.org/licenses/by/3.0/us/prairie pothole wetlandsdissolved organic matterapparent quantum yieldphotochemically-produced reactive intermediatesDatasethttps://doi.org/10.13020/D62C7G
