A spatial analysis of the groundwater emergence flood hazard in Long Island, New York, and coastal areas surrounding Long Island Sound in New York, Connecticut, and Rhode Island A spatial analysis of the groundwater emergence flood hazard in Long Island, New York, and coastal areas surrounding Long Island Sound in New York, Connecticut, and Rhode Island
Long Island, New York, and nearby coastal areas surrounding Long Island Sound are densely populated and, like other coastal areas, are susceptible to flooding from several potential sources, including stormwater from precipitation events, tidal flooding and storm surge, and groundwater emergence flooding. Groundwater emergence fooding refers to the intersection of a rising water table...
Multiple lines of evidence reveal rapid, seasonal watershed responses to enhanced weathering Multiple lines of evidence reveal rapid, seasonal watershed responses to enhanced weathering
Enhanced weathering accelerates carbon dioxide removal from the atmosphere through the rapid dissolution of land amendments of crushed, cation-rich rocks. The export of enhanced weathering dissolution products to drainage networks has important implications for carbon dioxide removal durability and measurement yet has received little attention. Here we observe rapid and pronounced...

Low-Streamflow Statistics for Unregulated Streams in Vermont
Below normal streamflows can intensify competing water demands and affect water quality, drinking-water supplies, and aquatic habitat. Estimating normal low-flow statistics is critical to support natural resource management. The current methods for estimating low-flow statistics at ungaged streams, particularly on small watersheds, are limited in Vermont. The USGS is computing low-flow statistics...
Predicting Cyanobacterial Harmful Algal Blooms at Lake Champlain Beaches
USGS, in cooperation with the Lake Champlain Basin Program, is evaluating machine learning models for predicting blooms of potentially harmful cyanobacteria, a damaging blue-green algae, at Lake Champlain beaches in Vermont and New York. Harmful cyanobacterial algal blooms (cyanoHABs) degrade the water quality of Lake Champlain and can threaten environmental and public health because the lake...
