Geospatial datasets of AUV observations including bottom dissolved oxygen in Great South Bay, Long Island, New York, August 2016 This dataset provides locations and values of water quality parameters from a four-day survey conducted between August 23, 2016 and August 26, 2016 using an Autonomous Underwater Vehicle (AUV) in Great South Bay, New York. Measured parameters include bottom dissolved oxygen (DO), salinity, specific conductance, water temperature, and pH. During the four day period, data was collected along 15 transects of the Great South Bay, totaling 60,480 observation points. From these point data, rasters showing the spatial distribution of bottom dissolved oxygen were generated using an interpolator in a GIS. A unique raster is provided for each day of the survey. All data files for download are available within 'Child...

Many of the densely populated areas along the East Coast (i.e. Long Island, New York) are served by OWDS. Approximately 75 percent of Suffolk County, New York, residents rely on simple OWDS such as a series of cesspools (ground pits lined with cement blocks or rings without a sealed bottom) and septic systems. Cesspools provide minimal wastewater treatment, typically...
