Geospatial datasets of AUV observations including bottom dissolved oxygen in Great South Bay, Long Island, New York, August 2016

This data provides an interpolated raster surface of dissolved oxygen values across a region covered by an August 26, 2016 AUV survey. The raster was generated by using a natural neighbors interpolator within a GIS on the empirical data set. This interpolator was chosen due to the non-normal distribution observed among the data, and its ability to produce smoother approximations than alternative interpolation methods. During the August 26 survey, 10,577 data points were collected in Patchogue Bay. A subset of 2644 (25%) random points were removed prior to interpolation to check for the accuracy of the interpolated surface.
