Phytoplankton Data from Owasco, Seneca, and Skaneateles Lakes, Finger Lakes Region, New York, 2019–2020 (ver. 2.1, June 2023)

This U.S. Geological Survey (USGS) data release provides phytoplankton data collected as part of an advanced harmful algae bloom (HAB) monitoring study conducted in collaboration with the New York State Department of Environmental Conservation (NYSDEC). Samples were collected biweekly in association with continuous monitoring platforms in Owasco, Seneca, and Skaneateles Lakes, Finger Lakes Region, New York and one opportunistic bloom sample site at Emerson Park Boat Launch in Owasco Lake. The platforms were deployed from May-November in 2019 and June-October in 2020. This dataset includes all routine and quality assurance/quality control samples collected at the four sampling locations on the three lakes: three...

Delineation of the Freshwater-Saltwater Interface at Selected Public-Supply Wells Using Advanced Surface and Borehole Geophysical Techniques, in Eastern Suffolk County, New York

The combination of a complex hydrogeologic framework, narrow land masses surrounded by saltwater, and extensive ground-water public-supply pumpage has produced localized areas of elevated chloride concentrations in ground water. This project uses advanced surface and borehole geophysical methods to determine the extent of saltwater intrusion and road-salt plumes at selected sites in eastern Suffolk County, Long Island, NY. Two-dimensional resistivity sections have been integrated with borehole geophysical logs and water-quality data to produce cross-sections of road-salt plumes. Borehole geophysical logs are collected twice a year to determine variations in chloride concentration and thicknesses of intrusive...
