Summary

This data release contains phytoplankton data and vertical profile measurements of water quality and light in oligotrophic (low nutrient) lakes within the Adirondack Park, New York State. Data were collected between June and October 2021 at five lakes. Four lake locations (Nearshore, Open Water, Layer, Bloom) were sampled representing one of four sample types (Bottom Sediment, Surface Water, Bloom Material, Layer). Water-quality field parameters (water temperature, dissolved-oxygen concentration and percent saturation, pH, specific conductance, turbidity, chlorophyll fluorescence, phycocyanin fluorescence, and fluorescent dissolved organic material) were measured at each sampling location from the surface to the bottom of the water [...]

Summary

This data release contains phytoplankton data and vertical profile measurements of water quality and light in oligotrophic (low nutrient) lakes within the Adirondack Park, New York State. Data were collected between June and October 2021 at five lakes. Four lake locations (Nearshore, Open Water, Layer, Bloom) were sampled representing one of four sample types (Bottom Sediment, Surface Water, Bloom Material, Layer). Water-quality field parameters (water temperature, dissolved-oxygen concentration and percent saturation, pH, specific conductance, turbidity, chlorophyll fluorescence, phycocyanin fluorescence, and fluorescent dissolved organic material) were measured at each sampling location from the surface to the bottom of the water column. Photosynthetically Active Radiation (PAR) was measured at each Open Water site from the surface to the depth where PAR was less than 1 percent of the surface measurement. Bloom and Layer sample types were collected on an opportunistic basis, as observed. PhycoTech, Inc. identified and enumerated the phytoplankton in water and bottom sediments. Phytoplankton were identified to the lowest possible taxonomic level with abundance (reported as both natural units and cells) and biovolume reported.

Purpose

These data were collected to understand cyanobacterial occurrence and bloom development in oligotrophic (low nutrient) lakes within the Adirondack Park, New York. These data provide information about how physical, chemical, and biological conditions, including the cyanobacterial community changed through the algal growing season and among lakes with and without previously reported cyanobacteria harmful algal bloom conditions. This data release was produced in compliance with the open data requirements to make scientific data associated with USGS research efforts and publications available to the public.
