Evaluating the Efficiency of Data Assimilation

by Aaron Sidder 7 January 201914 June 2022

Information is lost when researchers combine statistical models and remote sensing data, but just how much is often unclear. A new study offers a framework to measure the inefficiency.

Organic Particles Affect Carbon Cycling in Boreal Waters

by Aaron Sidder 2 January 201928 March 2023

Dissolved organic carbon receives much of the focus in aquatic research, but a new study suggests that bulkier particulate matter may play a significant role in regulating carbon dioxide emissions.

Hydrology Dictates Fate of Carbon from Northern Hardwood Forests

by Aaron Sidder 12 October 201821 March 2022

As spring snowmelt and fall rains inundate northern hardwood forests with moisture, soil bacteria get moving and increase carbon exports to the atmosphere and into nearby water bodies.
