Optimization of a fiber optic freshwater DOM sensing device
Fiber optical arrangements are useful for measurement of aquatic chemical species, especially in waters of high chemical concentrations. An optical fiber spectrofluorometer device known as the "Hammerhead" was developed in the Hemond lab in 2015 and improved in 2016 to measure concentrations of …

An improved in situ sensing device for freshwater DOM characterization
DOC characterization of freshwater is poorly understood at areas of harsh or difficult to access, especially areas like peatland rainforest. In order to figure out the level of DOC transport, an in situ instrument was previously designed to measure the DOC concentration at remote locations. …
