New paper assesses how dams alter the ratios of macronutrients (nitrogen, phosphorus and silicon) delivered to the world’s oceans

The damming of rivers is one of the most impactful modifications of the flows of water and associated materials from land to sea. Included in these materials are nutrient elements like nitrogen and phosphorus, which are elements required by all life on Earth, and silicon, which is required by diatoms, the algae that account for the largest fraction of biological productivity of the oceans. Past studies have shown that changes in the ratios in which these nutrient elements enter the coastal oceans affect plankton communities, even causing harmful algal blooms or “red tides” to occur. In a new paper published in Geophysical Research Letters, (former) ERG researchers Taylor Maavara, Zahra Akbarzadeh and Philippe Van Cappellen use models of nitrogen, phosphorus, and silicon cycling in dam reservoirs to determine how the damming of rivers change the nutrient ratios delivered to coastal zones worldwide.

New paper examines the changes in sedimentary phosphorus burial following artificial fertilization of Lake 227 in the Experimental lakes Area

Over the past 50 years, phosphorus (P) has been added each year to Lake 227, making it the world’s longest experiment in P fertilization. Located in Canada’s Experimental Lakes Area, Lake 227 conclusively demonstrated that excess phosphate in lakes causes algal blooms, in turn leading to worldwide bans on phosphates in detergents, improvements in wastewater P removal, and reductions in fertilizer applications. A key question, however, is: Where did the P added to Lake 227 end up? This is where David O’Connell and Philippe Van Cappellen of the Ecohydrology Research Group, together with colleagues from Canada, Netherlands, and USA, turned to examining phosphorus in the sediments accumulating at the bottom of the lake.

New paper from Ecohydrology Research Group featured in CSA News

A recent paper co-authored by Ecohydrology Research Group members has been featured in the latest edition of CSA News, the magazine of the Crop Science Society of America, Soil Science Society of America, and American Society of Agronomy. The feature, titled “Carbon Cycling in Periodically Waterlogged Soils”, presents highlights of an experiment studying the effects of a fluctuating water table on organic matter dynamics in soil columns.

New publication links Urinary Stone Disease to geoenvironmental and climatic factors

The prevalence of Urinary Stone Disease (USD) or urolithiasis has been increasing over the past few decades. In this new paper published in Science of the Total Environment an international team from China University of Geosciences, Karlsruhe Institute of Technology and the Ecohydrology Research Group present evidence that the spatial distribution of USD can be explained to a large degree by geo-environmental conditions, including lithology, water chemistry and climate.
