Gavel, M.M.Hubbard, T.D.2021Digital data addendum: Analytical data and field observations from surficial geology and morphology of the Alaskan central Arctic Coastal Plain, 1981-1987tableReport of InvestigationRI 93-1AFairbanks, Alaska, United StatesAlaska Division of Geological & Geophysical Surveys6 p.https://doi.org/10.14509/30670Report of Investigation 93-1A, Digital data addendum: Analytical data and field observations from surficial geology and morphology of the Alaskan central Arctic Coastal Plain, 1981-1987, presents digitized station and sample locations and identifiers, and analytical data tables for grain size, amino acid, thermoluminescence, carbon-14, palynology, microfossil, and wood identification from 1980-1987 surficial geologic field investigations along Alaska's North Slope. This data release also provides the project's scanned field notes, measured section diagrams, and laboratory observations. The study area encompassed twenty-five 1:63,360-scale quadrangles between the Colville and Hulahula rivers. The geologic mapping, analytical data, interpretations, and measured sections resulting from these investigations were published in 1993 (Rawlinson, 1993). All files are available from the DGGS website: http://doi.org/10.14509/30670.In 2018, DGGS joined the Department of Natural Resources and the North Slope Borough Arctic Strategic Transportation and Resources (ASTAR) project. DGGS initiated significant work to use historic and newly acquired geologic and geospatial data to evaluate sand and gravel resources across the North Slope. To support this research, we scanned the 1980-1987 project field notes and reformatted published source data into digital files optimized for visualization and data analysis using ArcGIS software.>age: Carbon 14 and thermoluminescence data >animo_acid: Age group data and acid ratios >grain_size: Mechanical sieve data, depth of collection >field-notebook-scans: Collection of scanned field notes >microfossil: Fossil species identification >pollen: Samples with pollen species identification >samples: Sample Numbers, type of analyses, depth of collection >stations: Station numbers and locations >wood_identification: Wood sample species identification19811993ground conditioncompleteNone planned-151.822780-144.03333070.55802069.240280ISO 19115 Topic CategorygeoscientificInformationAlaska Division of Geological & Geophysical SurveysAge DatesAnalyses and SamplingCoastalDepositional EnvironmentEolianFluvialGeochemistryGeochronologyGeologicGeologyGeomorphologyGlacial ProcessesGravelHazardsLacustrineMarine TransgressionsMeasured Stratigraphic SectionPaleontologyPalynologyPermafrostPermafrost and PeriglacialPingosPlant ChemistryResourcesSandSand and GravelSea Level ChangesSedimentationSize AnalysisSortingSurficialThaw LakesAlaska Division of Geological & Geophysical SurveysBack PointBeechey PointBodfish IslandCamden BayCanning RiverCarter CreekColville RiverColville River DeltaFawn CreekFoggy Island BayHarrison BayHulahila RiverIgnek CreekItkillik RiverItkilyariak CreekKachemach RiverKadleroshilik RiverKalubik CreekKatakturuk RiverKavearak PointKavik RiverKuparuk RiverMarsh CreekMiluveach RiverNanook CreekPoint StorkersenPrudhoe BayPutuligayuk RiverRed HillSadlerochit RiverSagavanirktok RiverSagavanirktok River DeltaSakonowyak RiverShaviovik RiverSimpson LagooonStaines RiverTamayariak RiverUblutuoch RiverUgnuravik RiverWeller CreekThis report, map, and/or dataset is available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (see contact information below).Any hard copies or published datasets utilizing these datasets shall clearly indicate their source.

Please contact us using the e-mail address provided above when possible.The State of Alaska funded this work as a component of the ASTAR project. We appreciate the hours of work conducted by our intern, Alex Terry, sorting and scanning the original field documents. The collective DGGS ASTAR work supports a collaborative effort between the North Slope Borough and the Department of Natural Resources to strengthen community infrastructure and facilitate access to arctic resources while enhancing the quality of life and economic opportunities for North Slope communities. It also provides valuable information for land-use management and planning decisions. Concurrent work to identify and catalog corresponding geologic materials samples was funded by the USGS National Geological and Geophysical Data Preservation Program (NGGDPP) awards G15AP00147 and G17AP00063.Analytical data and field station locations were auto-read from the appendices using optical character recognition converted into tabular data files. When possible, we used the lab correspondence, field notebooks, and other loose papers associated with Rawlinson's 1993 publication to augment or clarify the published summary data and to verify each sample's field station and sample numbering. For the most part, we were able to correlate field station numbers, sample numbers, map numbers, and reported depth to visualize and organize the data using a relational database hierarchy. However, achieving full referential integrity throughout the entire dataset would require discarding non-compliant data or assumptions unsupported by the field notes or published documentation. Due to these limitations, we decided to eliminate cross-table data dependencies and provide root sample metadata in each table.Not applicableThis publication is a digital data addendum to allow for visualization and data analysis using ArcGIS or other software. Users must consult the originating DGGS Report of Investigations (Rawlinson, 1993) for geologic context and supporting documentation. This data release is complete.Field station locations were auto-read from the appendices using optical character recognition converted into tabular data files. We converted field station locations (Rawlinson, 1993, app. C) from degree-minute-second to decimal-degree notation. We then quality controlled the exported field station locations using ArcGIS to visually compare them to corresponding plotted locality in scanned and georeferenced geologic maps. Offsets between the plotted and calculated points were generally in the range of 50-200 meters. In cases of larger offsets, we provide coordinates digitized from the scanned maps.Rawlinson, S.E.1986Surficial-geologic map of the Beechey Point A-3 Quadrangle, AlaskaReport of InvestigationRI 86-8Fairbanks, Alaska, United StatesAlaska Division of Geological & Geophysical Surveys1 sheet, scale 1:63,360https://doi.org/10.14509/240763360paper1986publication dateRawlinson, S.E., 1986scanning and optical character recognitionRawlinson, S.E.1986Surficial-geologic map of the Beechey Point A-4 Quadrangle, AlaskaReport of InvestigationRI 86-9Fairbanks, Alaska, United StatesAlaska Division of Geological & Geophysical Surveys1 sheet, scale 1:63,360https://doi.org/10.14509/240863360paper1986publication dateRawlinson, S.E., 1986scanning and optical character recognitionRawlinson, S.E.1986Surficial-geologic map of the Beechey Point B-2 Quadrangle, AlaskaReport of InvestigationRI 86-10Fairbanks, Alaska, United StatesAlaska Division of Geological & Geophysical Surveys1 sheet, scale 1:63,360https://doi.org/10.14509/240963360paper1986publication dateRawlinson, S.E., 1986scanning and optical character recognitionRawlinson, S.E.1986Surficial-geologic map of the Beechey Point B-3 Quadrangle, AlaskaReport of InvestigationRI 86-11Fairbanks, Alaska, United StatesAlaska Division of Geological & Geophysical Surveys1 sheet, scale 1:63,360https://doi.org/10.14509/241063360paper1986publication dateRawlinson, S.E., 1986scanning and optical character recognitionRawlinson, S.E.1986Surficial-geologic map of the Beechey Point B-4 Quadrangle, AlaskaReport of InvestigationRI 86-12Fairbanks, Alaska, United StatesAlaska Division of Geological & Geophysical Surveys1 sheet, scale 1:63,360https://doi.org/10.14509/241163360paper1986publication dateRawlinson, S.E., 1986scanning and optical character recognitionRawlinson, S.E.1990Surficial geology and morphology of the Alaskan central Arctic Coastal PlainPublic Data FilePDF 90-27Fairbanks, Alaska, United StatesAlaska Division of Geological & Geophysical Surveys326 p., 6 sheets, scale 1:63,360https://doi.org/10.14509/146163360paper1990publication dateRawlinson, S.E., 1990scanning and optical character recognitionRawlinson, S.E.1993Surficial geology and morphology of the Alaskan central Arctic Coastal PlainReport of InvestigationRI 93-1Fairbanks, Alaska, United StatesAlaska Division of Geological & Geophysical Surveys172 p., 6 sheets, scale 1:63,360https://doi.org/10.14509/248463360paper1993publication dateRawlinson, S.E., 1993scanning and optical character recognitionScanning and optical character recognition - Analytical data and field station locations were auto-read from the appendices using optical character recognition converted into tabular data files.
