Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    Photochemical Data of Stormflow Samples Collected Near Minneapolis and St. Paul, Minnesota from 2014-September to 2015-October

    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.
