Ensuring clean water for people and ecosystems is widely recognized as a central “grand challenge” in freshwater science, one that requires an ability to understand, predict, and manage changes in water quality.  Nutrient over-enrichment of freshwaters constitutes a primary threat to human health and aquatic ecosystem integrity.  In the first portion of this seminar I will present recent, modeling-based advances in our understanding of regional-to-global scale patterns, sources, and sinks of aquatic nutrients, with a focus on dissolved inorganic phosphorus.  In addition, as abundant (over 1 million world-wide) managed systems, reservoirs strongly affect the amounts and ratios of nutrients transported downstream through watersheds, and collectively constitute a major greenhouse gas source.  I will present striking early results from a case study, suggesting that appropriate reservoir management has potential to both enhance quality of water released to downstream reaches and to reduce water-to-air greenhouse gas fluxes.
