A Powerful Solution? Buoys Tracking the Potential of Ocean Alkalinity Enhancement
The climate is a complex network of interconnected systems. Halting the cascading impacts of climate change is not as straightforward as cutting anthropogenic greenhouse gas emissions. Even if these emissions ceased entirely today, it would take many thousands of years for carbon dioxide (CO2) to return to pre-industrial levels. Removal of CO2 from the atmosphere is also necessary to keep global warming within the 2°C limit stipulated in the 2015 Paris Agreement . The Ocean as a Carbon Sink The ocean is the world’s largest carbon sink–it absorbs 30% of all carbon dioxide emissions and captures 90% of the excess heat generated by these emissions.
Three Decades of Research at Acton Lake
A multi-disciplinary team at Miami University, Ohio, has been studying the environmental change at Acton Lake for over three decades. Using three different NexSens buoys over this time, the team has an incredible archive of data that is helping build a picture of Acton’s past, present, and future. Until recently, a NexSens CB-50 buoy was used alongside other environmental monitoring at Acton Lake. In May 2025, the Miami team deployed a new XB-200 buoy , future-proofing their ongoing monitoring using real-time buoy systems. Acton Lake, a small hypereutrophic reservoir in southwest Ohio, covers 2.4km² and has a maximum depth of about 8m. The dam was built in 1956, and the lake has a large agricultural watershed.
2025 Essential Water Monitoring Gear
Stay ahead of the curve with five of the top water monitoring products for 2025. Technological advancements and manufacturing innovations are leading to better quality data, improved price points, and enhanced user experience. And, while the ‘essentials’ list includes several new products, two tried-and-true measurement instruments continue to take a top spot for portable instrumentation. These five products were developed by industry-leading suppliers, and in addition to extensive manufacturer testing, our science team tested and verified each instrument’s performance at the Fondriest Center for Environmental Studies . NexSens X3 Data Logger The X3 is an all-in-one environmental data logger that makes remote data collection possible in a variety of applications.
Eyes on Ohio Waters: Water Quality Monitoring in the Huntington District
The world of water quality monitoring is vast and diverse, with environmental professionals working in the field in a variety of environments and applications. From watershed monitoring to source water management , a career in water quality provides opportunities worldwide. Thaddaeus Tuggle chose to pursue a career in water quality after attending Cedarville University and working closely with the environmental faculty, who instilled in him a passion for working in streams, improving water quality, and educating people about the overall importance of watershed stewardship. After graduating, Tuggle worked for the Knox Soil & Water Conservation District in central Ohio before eventually returning to Marshall University in West Virginia.
