Photogrammetric digital surface models and orthoimagery for the continuous coastline, Wales to Platinum, Alaska, segment A: Wales to Teller

Aerial photographs of the coastline from Wales to Teller were collected on August 27, 2015 - August 28, 2015. The photographs were processed using Structure-from-Motion (SfM) photogrammetric techniques. Global Positioning System (GPS) checkpoints were collected via a Global Navigation Satellite System (GNSS) survey conducted between August 15 and September 14, 2015. For the purposes of open access to elevation and orthoimagery datasets in coastal regions of Alaska, this collection is being released as a Raw Data File with an open end-user license. This file is a single-band, 32-bit float DSM (digital surface model) which represents surface elevations of buildings, vegetation, and uncovered ground surfaces in meters with 20 cm GSD. The No Data value is set to -32767. The file employs LZW compression.

Lidar-derived elevation data for land near Grewingk Glacier and Halibut Cove Lagoon, Southcentral Alaska, collected October 12-13, 2021

Lidar-derived elevation data for land near Grewingk Glacier and Halibut Cove Lagoon, Southcentral Alaska, collected October 12-13, 2021, Raw Data File 2023-2, uses aerial lidar to produce a classified point cloud, digital surface model (DSM), digital terrain models (DTM), and intensity model of land near Grewingk Glacier and Halibut Cove Lagoon, located in Southcentral Alaska (cover figure). Aerial data were collected October 12-13, 2021, and subsequently processed in a suite of geospatial processing software. Ground control data were collected on October 12, 2021. This data supports a paraglacial rock slope destabilization study at Grewingk Glacier and Grewingk Lake and will be used to assess and characterize an ongoing landslide hazard. All files can be downloaded from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/30958).

High-resolution lidar data for infrastructure corridors, Gulkana Quadrangle, Alaska

In advance of design, permitting, and construction of a pipeline to deliver North Slope natural gas to out-of-state customers and Alaska communities, the Division of Geological & Geophysical Surveys (DGGS) has acquired lidar (light detection and ranging) data along proposed pipeline routes, nearby areas of infrastructure, and regions where significant geologic hazards have been identified. Lidar data will serve multiple purposes, but have primarily been collected to (1) evaluate active faulting, slope instability, thaw settlement, erosion, and other engineering constraints along proposed pipeline routes, and (2) provide a base layer for the state-federal GIS database that will be used to evaluate permit applications and construction plans. Hillshade (shaded relief) images, produced from bare-earth DEMs provide a visual representation of topographic relief.

Alaska Coastal Profile Tool (ACPT)

Elevation profiles are a type of temporal data that can be used to understand coastal environments, document change and assess vulnerability. The value of these shore-normal measurements increases when sites are revisited seasonally and/or interannually due to the dynamic range of coastal landforms. These static measurements of the shoreface have been collected by a number of stakeholders in Alaska since the 1960s, but, have not historically been published or readily accessible. In cooperation with the Alaska Ocean Observing System, the Alaska Division of Geological & Geophysical Surveys (DGGS) has designed a universal repository to house these coastal measurements. This new database has an interactive map interface that enables easy access to existing profile locations to encourage repeat observations. The database has been designed to accommodate data sets collected with differing techniques, including differential leveling, survey-grade GPS or extraction from digital elevation models. Non-DGGS profile measurements, including community-led efforts, and data sets from state, federal and academic partners have also been incorporated into the database. Contributions from other entities are welcomed. The readily-accessible nature of this database is intended to promote partner and local involvement in community-based coastal monitoring.

Geology of Kasatochi volcano, Aleutian Islands, Alaska

Kasatochi is a small, isolated island volcano in the center of the Aleutian Island chain. It consists of a roughly circular cone approximately 3 km in diameter with a lake-filled central crater that is 1.2 km in diameter and extends from the highest point on the island to sea level. The oldest unit recognized is a thick series of mid-Pleistocene glaciovolcanic deposits consisting of autobrecciated lava, lahars, and volumetrically minor lava masses that we believe to have been emplaced underneath a regional ice cap. This unit is unconformably overlain by several massive Holocene lavas, above which lies a thick sequence of latest-Holocene pyroclastic deposits likely deposited during the crater-forming eruption. The 2008 eruption enlarged the preexisting crater, and produced pyroclastic density currents, surges, and fall that blanketed the entire island except for the crater wall and steep, seaward-facing cliffs on the flanks. 2008 deposits initially extended the shoreline seaward by up to 500 m. A multidisciplinary effort to document recovery of the ecosystem was initiated, and this study of the geology of the island was undertaken as part of that effort. This collection of electronic data is a supplement to the Geology of Kasatochi volcano, Aleutian Islands report and geologic map. It provides spreadsheets of sample metadata and major and trace element XRF and ICP/MS data which are included in the appendices; electron microprobe mineral analyses which are discussed in the report, but not tabulated elsewhere; and high resolution versions of panoramic photographs (appendix 1) and photomicrographs (appendix 7).

Shoreline change at Alaska coastal communities, Goodnews Bay, Alaska

The Division of Geological & Geophysical Surveys has analyzed long-term shoreline change at 48 Alaska communities. Shoreline datasets were compiled from previously published U.S. Geological Survey assessments and created from historical and recent aerial images by the Alaska Division of Geological & Geophysical Surveys. Shorelines were analyzed to calculate shoreline change rates every 25 meters along coastlines and tidally influenced riverbanks using the Digital Shoreline Analysis System (DSAS; Himmelstoss and others, 2018). The geodatabase for each community includes shoreline positions, the alongshore baseline used to cast transects, and transects that include shoreline change rates and statistics. All files can be downloaded free of charge from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/30552).

Acute Ozone-Induced Transcriptional Changes in Markers of Oxidative Stress and Glucocorticoid Signaling in the Rat Hippocampus and Hypothalamus are Sex-Specific

The dataset is comprised of multiple data-frames. Our focus is on sex and brain region specific responses to ozone in a rat model. The PCR data describes the gene expression from listed brain regions resulting from ozone exposure. Complex enzymes were also assayed due to their sensitivity to oxidative stress using biochemical colorimetric assays. And finally, we collected data for oxidative stress artifacts such as protein carbonyl productions, total antioxidants, and enzyme activity.
