Cyanobacteria Assessment Network: Pilot study with Sentinel-2 derived chlorophyll data Cyanobacteria Assessment Network: Pilot study with Sentinel-2 derived chlorophyll data
Harmful algal blooms (HABs) affect global water quality, limiting uses like recreation and consumption because of excessive algal biomass and toxin production. These blooms cause surface scums, taste and odor issues, hypoxia, and negative health and socioeconomic impacts. The US Army Corps of Engineers (USACE) manages over 400 lakes and reservoirs and seeks to improve monitoring of HABs...
Deep learning models for mapping surficial geology in selected physiographic regions of New York Deep learning models for mapping surficial geology in selected physiographic regions of New York
Surficial geologic mapping is required for decisions including infrastructure and water-resource development and management. Deep learning, a type of machine learning that uses training data to self-learn and perform tasks, is explored as a tool to help increase efficiency of the labour- and time-intensive mapping process. Deep learning models were trained, and their potential to aid in...
Modeling legacy nitrogen transport under instantaneous, steady-state, and transient groundwater flow conditions Modeling legacy nitrogen transport under instantaneous, steady-state, and transient groundwater flow conditions
In hydrologic settings where groundwater discharge contributes substantially to surface waters, legacy nitrogen in groundwater can confound surface water nitrogen loads estimated exclusively from current terrestrial sources. Additionally, legacy nitrogen in groundwater can contribute to lagged responses to nitrogen management efforts. Some methods of estimating groundwater contributions...

Evaluating the Risks of Tire-Derived Compounds to Fish in the Chesapeake Bay Watershed
Tires contain a chemical known as 6PPD which prevents them from quickly breaking down. Microscopic tire particles, generated mainly from the friction of tires on roads, release 6PPD-quinone (6PPDQ) when they come into contact with oxygen. During precipitation events, 6PPDQ can be washed off roads, harming fish in nearby waterways. In response to requests from fishery managers, the USGS is studying...
Interactive Products to Assist with Geothermal Drilling
Geothermal energy is a clean and renewable source of heat derived from the Earth's natural thermal resources. Geothermal borefields are utilized to extract this thermal energy, providing heating for buildings in the winter and cooling in the summer. In New York, the adoption of geothermal energy at both residential and community scales is on the rise and is expected to see significant growth in...
