A Study of New Hampshire Ecosystems and Society uses fDOM to Monitor Water Quality

A network of aquatic monitors in New Hampshire tracks the complex interaction between how land is being used and climate over time—creating opportunities to address upcoming challenges to the ecosystem.   NH EPSCoR (funded by the National Science Foundation and partnered with more than seven NH academic institutions) is using 10 EXO2 sondes from YSI (a […]

Field Tests Show Strong Agreement Between EXO and 6-Series Time-Series Data in South Carolina Estuary

In March 2012, YSI (a Xylem brand) released its next-generation water quality sonde, the EXO2, which represents a number of advances in sensor and anti-fouling technology. To ensure that a transition to the EXO2 would not introduce discontinuities into long-term data sets established with existing YSI 6-Series sondes, a field comparison of the two sonde […]
