    Optical and photochemical data of temperate wetland samples collected in Minnesota, USA from 2014-August to 2015-October

    Wetland surface water samples were collected from 39 sites throughout Minnesota, USA between 2014-August and 2015-October. Optical and photochemical parameters of the samples were measured under controlled laboratory conditions. The data were collected to identify environmental variables that constrain the yield of triplet excited states of dissolved natural organic matter. Apparent quantum yields of these triplet states were measured using the chemical probe, 2,4,6-trimethylphenol, under a broadband xenon-arc lamp with a 290-nm wavelength filter.

    Photochemical Data of Stormflow Samples Collected Near Minneapolis and St. Paul, Minnesota from 2014-September to 2015-October
    (2017-08-24) McCabe, Andrew J; Arnold, William A; arnol032@umn.edu; Arnold, William A
    Stormflow samples were collected from 31 sites near Minneapolis and St. Paul, Minnesota between 2014-September and 2015-October. Optical and photochemical parameters of the samples were measured under controlled laboratory conditions. The data were collected to better understand the way in which land cover with variable levels of human impact influence the formation rate and yield of triplet excited states of dissolved natural organic matter (3DOM*). Rates of formation (Rf,T) and apparent quantum yields (AQYT) were measured for 3DOM* using the chemical probe, 2,4,6-trimethylphenol, under a broadband xenon-arc lamp with a 290-nm wavelength filter.
