These data include: depth, velocity magnitude, velocity direction, navigational data, ADCP temperature, and channel profile. Water-Quality and Velocity data were obtained to address nearshore nutrient transport. 20150602 20180921 ground condition Complete None planned -79.024722 -76.199694 43.597444 43.245 USGS Thesaurus Water Quality Water Velocity ADCP Bathymetry USGS Metadata Identifier USGS:5ee128d382ce3bd58d7be788 United States Lake Ontario New York USGS Metadata Identifier USGS:5ee128d382ce3bd58d7be788 none none Benjamin N Fisher Northeast Region: NEW YORK WATER SCI CTR Hydrologic Technician mailing and physical
