Distinguishing between Sources of Natural Dissolved Organic Matter (DOM) Based on Its Characteristics
Vogt, Rolf David; Porcal, Petr; Hejzlar, Josef; Paule‐Mercado, Ma. Cristina; Haaland, Ståle Leif; Gundersen, Cathrine Brecke; Orderud, Geir Inge; Eikebrokk, Bjørnar (Peer reviewed; Journal article, 2023)Increasing levels of dissolved organic matter (DOM) in watercourses in the northern hemisphere are mainly due to reduced acid rain, climate change, and changes in agricultural practices. However, their impacts vary in time ... -
