Monitoring Nutrients and Water Quality in Ohio Wetlands
The ecological importance of wetlands cannot be overstated, serving as unique habitats for a variety of species and playing a critical role in nutrient cycling. Yet, many of these environments have deteriorated over the years due to pollution, rising temperatures, and added stress from human intervention like damming, diking, and channeling for irrigation. To bring these ecosystems back, wetland management and restoration have become key issues for environmental agencies and resource managers. To give wetlands the best chance at recovery and maximize efficiency, data-driven restoration efforts are essential.
Monitoring Aquatic Ecosystems: How Science Drives Waterway Management in Northwest Georgia
The University of Georgia is home to multiple labs that focus on monitoring aquatic ecosystems and organisms across the state. The River Basin Center connects these monitoring efforts with external partners, including government agencies and NGOs, to inform management and restoration of the state’s waterways. Phillip Bumpers is a Postdoctoral Associate in the Rosemond lab and the Wenger lab at the Odum School of Ecology and an affiliate of the River Basin Center. An aquatic ecologist, Bumpers’ research focuses on quantifying how environmental variability shapes aquatic ecosystems and understanding the drivers of these trends.

Monitoring New Hampshire’s Aquatic Ecosystems: Continuous Data Collection in the Lamprey River Watershed
New Hampshire’s aquatic ecosystems provide a range of ecosystem services to the state and region. Resources and services like clean water, carbon storage, climate regulation, nutrient regulation, and opportunities for recreation all depend on New Hampshire’s aquatic ecosystems remaining healthy. Jody Potter, an analytical instrumentation scientist at the University of New Hampshire (UNH), is studying these aquatic ecosystems in hopes of developing an improved understanding of ecosystem services and their interactions with climate change, climate variability, and land use changes.
Monitoring Water Pollution in Keweenaw Bay
As much as climate change and pollution impact current generations and present environmental conditions, the compounding damages will continue to wreak havoc against generations to come if no actions are taken. This idea is central for scientists who focus their research on monitoring, analyzing and responding to environmental data. Researchers like Dylan Friisvall, the water quality technician for the Keweenaw Bay Indian Community (KBIC) Natural Resources Department (NRD) , have dedicated their careers to monitoring pollution and water quality in order to protect resources for the future. “One of the best parts of my job is just being outdoors, it makes my day go by faster because I get to enjoy the fresh air, and help do my part in protecting the environment,” says Friisvall.
