This data provides an estimated 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 interplator 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. There are three files available for download in the 'Attached Files' section below. There is a zip file which contains the interpolated dissolved oxygen surface, an xml file which contains metadata, and a layer file which can be used to import the layer's symbology.

Mono Lake is a hypersaline (~85 ppt), alkaline (pH 9.8), closed-basin lake located in the eastern Sierra Nevada Mountains of California, USA (38°N, 119°W). Water enters the lake primarily from snowmelt and exits by evaporation (~1 m/yr). This hydrological condition, plus weathering reactions in the lake’s tributaries, produce the uniquely high salinity and pH characteristic of Mono Lake (Garrels & MacKenzie, 1967). These properties also tightly tie lake levels and water chemistry to climate, with modern and Pleistocene high stands correlated with wet Sierra Nevada conditions (Benson et al. 1998). Mono Lake is typically monomictic, with thermal-driven summer stratification that is disrupted by winter, wind-driven...

Groundwater data were collected in the spring and fall of 2008 from three sites representing different geological settings and biogeochemical conditions within the surficial glacial aquifer of Long Island, NY. Investigations were designed to examine the extent to which average vadose zone thickness in contributing watersheds controlled biogeochemical conditions and processes, including dissolved oxygen concentration (DO), oxidation-reduction potential (Eh), dissolved organic carbon concentration (DOC), and microbial dinitrogen (N2) production. Greatest N2 production was observed at the south shore of Long Island, which is characterized by a thin vadose zone, low DO and Eh, and relatively high DOC. Limited N2 production...

In a crude-oil-contaminated sandy aquifer at the Bemidji site in northern Minnesota, biodegradation of petroleum hydrocarbons resulted in transient increases in magnetic susceptibility under high water table conditions. The magnetic susceptibility subsequently decreased again when the water table dropped. This data set was assembled to illustrate the cause of the magnetic susceptibility changes. These data show that alkalinity is high and dissolved oxygen is low in the area where the increased magnetic susceptibility is found. The decrease in the magnetic susceptibility can be attributed to the long term decline in sediment Fe(III) concentrations with time. The decrease is caused by iron reducing bacteria converting...
