    dct:description "This data provides an estimated raster surface of dissolved oxygen values across a region covered by an August 24, 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 24 survey, 13,910 data points were collected. A subset of 4452 (25%) random points were removed prior to interpolation to check for the accuracy of the interpolated surface." ;
