The response of streams to changes in atmospheric deposition of sulfur and nitrogen in the Adirondack Mountains
Charles T. Driscoll, Shuai Shao, Timothy J. Sullivan, Todd C. McDonnell, Barry P. Baldigo, Douglas A. Burns, Gregory B. Lawrence
2020, Final Report 20-19
Acidic deposition is the result of upwind sulfur (S) and nitrogen (N) emissions into the atmosphere from human activities. Environmental impacts from acidic deposition across forested landscapes include acidification of soil and drainage water, depletion of available soil nutrient bases, and impacts to and changes in forest and aquatic species...

Identifying and assessing priority transboundary aquifers along the United States- Mexico border
Nathaniel Kyle Pasley
2020, Report
Many of the 15 million inhabitants along the United States-Mexico border derive fresh water from transboundary aquifers straddling and extending far beyond the political boundary separating the two countries. The previous lack of a large-scale cooperative and structured data collection effort and groundwater management strategy for the region has left...

Tao Ruan, Qingkai Kong, Yawen Zhang, Sara K. McBride, Qin Lv
2020, Conference Paper, 2020 IEEE International Conference on Parallel and Distributed Processing with Applications, Big Data & Cloud Computing
Previous research has shown that online social networks can provide valuable insights regarding collective human responses to extreme natural events, such as earthquakes. Most previous studies focused on one large earthquake, while the 2019 Ridgecrest earthquakes involved two significant earthquakes occurring within a short period of time (a M6.4 foreshock...

2020, Conference Paper, Proceedings of the Fire Continuum-Preparing for the future of wildland fire
Wildland fires burn millions of forested hectares annually around the world, affecting biodiversity, carbon storage, hydrologic processes, and ecosystem services largely through fire-induced tree mortality (Bond-Lamberty et al. 2007; Dantas et al. 2016). In spite of this widespread importance, the underlying mechanisms of fire-caused tree mortality remain poorly understood, (Hood...
