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 23, 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 23 survey, 13,910 data points were collected. A subset of 3477 (25%) random points were removed prior to interpolation. The interpolated raster values were compared with the subset to diagnose the accuracy of interplotion. 3076 out of 3477 (88.45) of the points were within 97.5% of the raster value.
