Developing New Data-Informed Management of the Mississippi Embayment in Memphis
The Center for Applied Earth Science and Engineering Research (CAESER) at the University of Memphis oversees dozens of projects regarding the environment each year, helping to improve resource management in the region. Rodrigo Villalpando-Vizcaino, a Research Assistant Professor at the university, spends his time at the center monitoring groundwater resources. He explains, “I’m an interesting combination of project management, engineering, and geology, and just trying to bridge the gap between fields with a focus on anything related to water—mostly groundwater.” Updating Management Strategies in Memphis Tennessee, specifically Memphis’ reliance on the Mississippi embayment, provides unique research opportunities to scientists like Villalpando-Vizcaino.
Flow Photo Explorer: Studying Flows in the Penobscot River Basin
The flow dynamics of rivers and streams play an essential role in the chemical and physical functions of aquatic ecosystems. In Maine, varying flows in the Penobscot River Basin have impacted the health of the ecosystem, water resource use, and habitat suitability for native species—topics of particular concern to the Penobscot Indian Nation , who have been protecting and managing the waterway for millennia. Parts of the Penobscot basin have been monitored by the USGS stream gage network, which covers larger streams and rivers but excludes many of the small streams found on tribal lands.
No Red Herrings: Data Driving the Largest Salt Marsh Restoration in the NE USA
The Herring River system encompasses around 1,000 acres in the Towns of Wellfleet and Truro, Massachusetts. In 1909, the Chequessett Neck Road dike was built at the river’s mouth, drastically limiting tidal flow. Today, it’s one of the most restricted estuaries in the northeastern United States. As a result, the area has suffered environmental decline, including poor water quality, hypoxia, lower pH, and salt marsh degradation. In 2023, the Town of Wellfleet received $14.7 million from NOAA’s Office of Habitat Conservation to fund the Herring River Restoration Project (HRRP). Francesco Peri, President and CEO at Charybdis Group LLC, uses a network of NexSens data loggers to monitor water level and water quality on the Herring River.
Monitoring Habitat Suitability and Water Quality in Northwest Arkansas Springs
Northwest Arkansas has seen an economic, industrial, and population boom in recent years as a result of expanding businesses, which have created thousands of jobs in the region and the mass migration of employees and construction companies. However, with this growth has come rapid urbanization and the degradation of the natural landscape, specifically the freshwater springs that can be found throughout the region. These springs are critical habitat centers for native wildlife, home to threatened and endangered fish, and those that have yet to be listed. Zach Moran, Assistant Professor of Fisheries Science at Arkansas Technical University, is working to help monitor these habitats and provide key data that will hopefully inform future development in the region.
