Kentucky Karst Dye Trace Database, Sarah M. Arpin, Benjamin W. Tobin, Maaz Fareedi, Adam Link, James C. Currens
Kentucky Karst Dye Trace Database, Sarah M. Arpin, Benjamin W. Tobin, Maaz Fareedi, Adam Link, James C. Currens
Research Data--KGS
This dataset provides the geographical locations of karst groundwater basins, groundwater flowpaths, and dye injection/recovery points in Kentucky. Dye tracing is a common method used for understanding groundwater movement. Dye is poured (or injected) into a sinking stream, well, sinkhole, or body of water, where it is carried down-gradient by flowing water. The locations at which dye is recovered (typically at artesian springs) indicates a connection from injection to recovery site. This connection is refered to as a groundwater flowpath. Conducting multiple dye traces across an area allows for the interpretation of regional groundwater flow by assessing where flowpaths either …

New Surficial Geologic Mapping In Kentucky (2021-2022), Matthew Massey, Antonia Bottoms, Max Hammond Iii, Ann Hislop, Meredith Swallom, Michele M. Mchugh
Research Data--KGS
New surficial geologic mapping was performed in nine new 7.5-minute quadrangles in Hardin, Meade, Breckinridge, Grayson, Hart, and Larue Counties, Kentucky.
Quadrangles include Big Clifty, Big Spring (Hardin county only), Custer (Hardin County only), Flaherty, Madrid (Hardin county only), Millerstown, Summit, Tonieville (Hardin county only), and Upton.
Mapping data for each of the nine quadrangles is captured in a ZIP file that contains an ESRI geodatabase and associated FGDC-compliant metadata files (.xml).
The geodatabase is a relational geodatabase of spatial and non-spatial data that conforms to "GeMS (Geologic Map Schema)--a standard format for digital publication of geologic maps", available at …
Kentucky Geological Survey Landslide Inventory [2023-03], Matthew M. Crawford
Kentucky Geological Survey Landslide Inventory [2023-03], Matthew M. Crawford
Research Data--KGS
The KGS landslide inventory provides the locations of known landslides and areas susceptible to debris flows. Various types of landslides are represented including slides, flows, rockfalls, and creep. The data are available as ArcGIS geodatabase feature classes. Landslide locations and associated attributes are compiled from Kentucky Geological Survey research, published maps, state and local government agencies, the public, and media reports. A confidence ranking system assigns a value to each feature. A description of the feature classes is here: https://kgs.uky.edu/kgsmap/helpfiles/landslide_help.shtm
The inventory viewed in a GIS with geology, soils, slope or other terrain-based data can serve as a basis for …

Civil Engineering Research Data
These data are the geomorphologic and land information system-based soil moisture estimates from assimilation of NASA SMAP satellite-based observations and NOAH 3.6 Land Surface Model estimates over known landslides in Eastern Kentucky. Additionally Long Short-Term Memory Recurrent Neural Network and logistic regression machine learning codes, as well as an Application programming interface code are included. Finally, in-situ data from Eastern Kentucky is included.

Elastic Thickness And Crust-Mantle Interface Models Of Tharsis Bulge On Mars And Surrounding Areas, R. T. Ratheesh-Kumar, Dhananjay Ravat, Paul Morgan
Elastic Thickness And Crust-Mantle Interface Models Of Tharsis Bulge On Mars And Surrounding Areas, R. T. Ratheesh-Kumar, Dhananjay Ravat, Paul Morgan
Earth and Environmental Sciences Research Data
The datasets contain the final models of spatial variation of elastic thickness (Te) and the depth to Moho or the Crust-Mantle Interface (CMI) of the Tharsis Bulge and the surrounding regions derived from the software package LithoFLEX. The models are based on the crustal density of 2900 kg/m3, which was selected from analyzing results of a range of densities, and other standard lithospheric parameters. The models are useful for understanding the nature and evolution of the Tharsis Bulge and the surrounding regions.

New Magnetic Field Models Of The Moon, Dhananjay Ravat, Michael E. Purucker, Nils Olsen
Earth and Environmental Sciences Research Data
We use L1-norm model regularization of |Br| component at the surface on magnetic monopoles bases and along-track magnetic field differences alone (without vector observations) to derive high quality global magnetic field models at the surface of the Moon. The practical advantages to this strategy are: monopoles are more stable at closer spacing in comparison to dipoles, improving spatial resolution; L1-norm model regularization leads to sparse models which may be appropriate for the Moon which has regions of localized magnetic field features; and along-track differences reduce the need for ad-hoc external field noise reduction strategies. We examine also the …
Crustal Density Variation Of The Eastern U.S., Henglei Zhang, Dhananjay Ravat, Anthony R. Lowry
Crustal Density Variation Of The Eastern U.S., Henglei Zhang, Dhananjay Ravat, Anthony R. Lowry
Earth and Environmental Sciences Research Data
EarthScope’s USArray Transportable Array (TA) has shortcomings for the purpose of interpreting geologic features of wavelengths less than the 70 km TA station spacing, but these can be overcome by using higher spatial resolution gravity data. In this study, we exploit USArray receiver functions to reduce non-uniqueness in the interpretation of gravity anomalies. We model gravity anomalies from previously-derived density variations of sedimentary basins, crustal Vp/Vs variation, Moho variation, and upper mantle density variation derived from body-wave imaging informed by surface wave tomography to estimate Vp/Vs. Although average densities and density contrasts for these seismic variations can be derived, …
Kentucky Structural Contours From Digitally Vectorized Geologic Quadrangles, Kentucky Geological Survey
Kentucky Structural Contours From Digitally Vectorized Geologic Quadrangles, Kentucky Geological Survey
Research Data--KGS
This dataset includes geologic stuctural contours of varying datums across Kentucky in shapefile format. These structural contours are compiled from structural contour layers published as a part of the individual Digitally Vectorized Geologic Quadrangles (DVGQ) datasets (by the Kentucky Geologic Survey: https://kgs.uky.edu/kygeode/services/pubs/?pubtype=DVGQ&searchtype=pubcategory). The original structural contours were mapped on the 7.5-minute (1:24,000 scale) series geologic maps published during the Kentucky geologic mapping program (Kentucky Geological Survey - U.S. Geological Survey from 1960 to 1989: https://kgs.uky.edu/kygeode/services/pubs/?pubtype=GQ&searchtype=pubcategory). The digital contours were subsequently digitized as a part of the DVGQ datasets during the geologic digital mapping program at KGS (1996 – 2007). Contoured …
