TL;DR: Analysis of the excitation emissions matrices indicated that amino-acid fluorophores dominated, consistent with DOM of microbial origin, with little humic-like fluorescence, in a supraglacial stream on the Cotton Glacier, Antarctica.

Journal ArticleDOI
Concentration-discharge relationships during an extreme event: contrasting behavior of solutes and changes to chemical quality of dissolved organic material in the Boulder Creek Watershed during the September 2013 flood.
TL;DR: In this article, the authors measured weathering-derived lithologic solutes (Ca, Mg, Na, K, and Si) and dissolved organic carbon (DOC) concentrations at two sites on Boulder Creek during the recession of peak flow.
Journal ArticleDOI
Toxicity of Volcanic-Ash Leachate to a Blue-Green Alga. Results Of A Preliminary Bioassay Experiment
TL;DR: Results showed that leachate was lethal to Anabaena flos-aquae cultures when diluted as much as 1 : lOO with culture medium, indicating that ash from the Mt. St. Helens volcano could have an effect on aquatic ecosystems in the areas of significant ashfall.
