A: Result -GEOLOGIC DATA COLLECTION AND INTERPRETATION: Continually gather and interpret new geologic field data in emerging areas of interest related to energy supply, mineral deposits, and geologic hazards.

Target #1: Publish new geologic mapping to address the state`s needs for evaluating energy resources, mineral resources, and geologic hazards. Methodology: Square miles of new, peer-reviewed geologic mapping published during the fiscal year to meet the state`s needs for evaluating energy resources, mineral resources, and geologic hazards. Square Miles of Published New Geologic Mapping Fiscal Year Square Miles Target FY 2025 4,068 4,000 FY 2024 366 3,000 FY 2023 190 2,000 FY 2022 2,603 2,000 FY 2021 4,230 1,500 FY 2020 2,015 1,500 FY 2019 1,311 1,500 FY 2018 606 1,500 FY 2017 1,846 1,500 FY 2016 15,927 1,500 FY 2015 2,645 1,500 FY 2014 665 500 FY 2013 1,203 520 FY 2012 1,533 800 FY 2011 1,078 2,702 FY 2010 1,546 3,086 Analysis of results and challenges: Detailed, reliable, and publicly available geologic maps and analytical data are critical for attracting new exploration investment in minerals and energy resources; identifying geologic hazards that pose risks to public safety, infrastructure, and the environment; and providing detailed information for state resource and land-use management. Detailed geological and geophysical maps of Alaska at scales needed for resource exploration, land-use management, and geologic-hazards assessment are scattered geographically and currently are available for only about 22 percent of the state, but Division of Geological & Geophysical Surveys field programs are increasing this coverage gradually each year. The division prioritizes the selection of new mapping areas in consultation with other state agencies, appropriate state boards and commissions, its Geologic Mapping Advisory Board, industry resource-interest groups, and other stakeholders. The division is committed to delivering the results of our extensive field mapping programs to the public in a timely manner. The division met its ambitious goal, publishing 4,068 square miles of new geologic mapping. Also, 17 previously published paper geologic maps, covering over 11,000 sq. mi., were converted into modern digital data, making this valuable resource more accessible to the public. The division currently has 10 new geologic map projects in production, and we expect at least 4,000 sq. mi. of published geologic mapping in FY2026.

A1: Core Service - Energy-related geologic information is produced in areas of poor geologic understanding and high energy-resource potential.

Target #1: Publish reports on energy-related geology that assist the energy industry and state agencies in exploring for and managing energy resources on state-interest lands. Methodology: Number of new reports published on energy-related geology during the fiscal year. New Reports Published on Energy-Related Geology Fiscal Year Fiscal Year Total Target FY 2025 5 5 FY 2024 3 5 FY 2023 3 8 FY 2022 10 6 FY 2021 6 6 FY 2020 4 6 FY 2019 11 7 FY 2018 4 7 FY 2017 4 8 FY 2016 16 12 FY 2015 17 11 FY 2014 9 9 FY 2013 9 5 FY 2012 6 7 FY 2011 2 1 FY 2010 9 7 Analysis of results and challenges: During FY2025, the Division of Geological & Geophysical Surveys (DGGS) published five reports providing new geologic data to assist energy exploration throughout Alaska. One paper provided new information on the age of the highly prospective Nanushuk Formation, a unit that hosts several recent, giant oil discoveries. This work extends DGGS` decades-long leadership in providing vital data on the Nanushuk and drawing attention to an important, but under-explored play. Three publications provided new mapping and age constraints on the geology that bounds the east side of Cook Inlet basin. The fifth paper released new data from the older parts of the Cook Inlet petroleum system, providing new information on the potential of these deeper rocks to serve as a seal to trap oil and gas. These data are also vital for potential carbon storage projects where seal integrity must be demonstrated prior to the injection of carbon dioxide. The section also submitted the final CORE-CM report to the U.S. Department of Energy (DOE), including uploading all new geochemical data to their database as required by the grant. DGGS successfully met the target number of energy reports, despite challenges with delays and federal funding. DGGS was selected for a major DOE critical minerals grant (CORE CM Phase 2) with funding scheduled for January 2025, but the award has yet to be distributed; thus, staff dedicated extensive time in preparation for work that did not occur. A DOE carbon storage grant proposal (Alaska Railbelt Carbon Capture & Storage [ARCCS]) required significant staff contributions and was awarded, but the grant has been terminated. The Energy section made significant progress standing up the new geothermal energy program, although many planned activities await permission to hire technical staff.

Target #2: Collect new geologic field data to support resource evaluations of areas prospective for oil, gas, and coal. Methodology: Square miles of sedimentary basins prospective for hydrocarbon resources evaluated with collection of new geologic field data during the calendar year. Square Miles of Prospective Hydrocarbon Resource Areas Evaluated with New Geologic Field Data Year Total Target 2025 9,000 8,500 2024 10,000 8,500 2023 13,500 10,000 2022 10,500 10,000 2021 9,000 7,500 2020 9,500 9,000 2019 10,000 9,000 2018 10,000 8,000 2017 9,000 8,000 2016 10,000 10,000 2015 16,000 18,000 2014 17,352 18,000 2013 17,436 40,000 2012 35,022 35,000 Analysis of results and challenges: The evaluation of new geologic field data in areas of high energy- resource potential is critical for attracting new industry players and providing detailed information for government, academia, and exploration companies. The Alaska Division of Geological & Geophysical Surveys met the FY2025 target of evaluating at least 8,500 square miles of hydrocarbon resource areas by conducting work on the Cretaceous stratigraphy and petroleum systems on the east-central North Slope. Additional evaluations were conducted in Cenozoic exposures in Matanuska Valley and the lower Kenai Peninsula which are relevant to the oil and gas geology of the Susitna and Cook Inlet basins. The FY2026 target is 9,500 square miles, reflecting anticipated resumption of field studies in Cook Inlet, focused on carbon storage potential. We are also planning to continue targeted stratigraphic studies and geologic mapping evaluating prospective regions on the east-central North Slope as part of the Arctic Strategic Transportation and Resources (ASTAR) program.

A2: Core Service - Minerals-related geological and geophysical information is produced in areas of limited information and high mineral-resource potential.

Target #1: Publish airborne geophysical survey data for Alaska`s minerals-interest lands. Methodology: Number of square miles of new airborne geophysical surveys of minerals-interest lands published during the fiscal year. Square Miles of Published Minerals-Related Airborne Geophysical Data Fiscal Year Square Miles Target FY 2025 2,761 4,000 FY 2024 14,389 13,000 FY 2023 12,725 4,741 FY 2022 9,141 5,800 FY 2021 1,000 7,800 FY 2020 0 4,200 FY 2019 5,477 5,566 FY 2018 0 5,500 FY 2017 0 3,430 FY 2016 4,552 4,500 FY 2015 2,318 2,300 FY 2014 2,176 2,500 FY 2013 1,267 1,200 FY 2012 850 800 FY 2011 742 700 FY 2010 653 640 Analysis of results and challenges: Much of Alaska`s lands with high mineral-resource potential have poorly exposed geology due to vegetation and soil cover. Airborne geophysical surveys measure physical properties of the earth; these properties correspond to various geologic features, and measurements are not affected by vegetation. Airborne geophysical survey data are invaluable for guiding subsequent ground-based geologic mapping, sampling, and associated mineral-assessment work. Only about 30 percent of prioritized mineral-bearing state lands have been geophysically surveyed, and the Division of Geological & Geophysical Surveys (DGGS) is committed to acquiring data in remaining areas of the state that have high mineral-resource potential, subject to available funding. The federal Earth MRI critical-minerals program was funded by the U.S. Congress in FY2020 (federal fiscal year 2019) to acquire airborne geophysical surveys, geologic mapping, and lidar over areas of the nation with critical mineral potential. Additional funds were added through the federal Infrastructure Investment and Jobs Act (IIJA) in FY2023, elevating federal funding levels through FY2027. DGGS has been engaged by the USGS to manage geophysical surveying contracts covering large portions of Alaska`s mineral districts. In FY2025 DGGS released 2,646 square miles of helicopter-flown electromagnetic data in the Kaiyuh Hills on the Seward Peninsula, and 115 sq. mi. of helicopter magnetic and radiometric data in the Tofty area, Interior Alaska. In late FY2025 and early FY2026, DGGS continued acquisition of fixed-wing and helicopter magnetic and radiometric data in the Kuskokwim mountains area of Southwest Alaska; new survey data blocks are scheduled for publication in FY2026.

Target #2: Publish reports and/or digital data sets on mineral-resource geology and mineral-industry exploration activity. Methodology: Number of reports published and/or digital datasets released during the fiscal year providing information on mineral-resource geology and mineral-industry exploration activity in Alaska. Published Reports and Datasets on Mineral-Resource Geology and Mineral-Industry Exploration Fiscal Year Fiscal Year Total Target FY 2025 14 10 FY 2024 11 10 FY 2023 9 15 FY 2022 34 10 FY 2021 15 20 FY 2020 48 14 FY 2019 17 10 FY 2018 11 8 FY 2017 10 8 FY 2016 22 12 FY 2015 25 17 FY 2014 17 5 FY 2013 4 4 FY 2012 3 4 FY 2011 5 4 Analysis of results and challenges: The Division of Geological & Geophysical Surveys` minerals-related geologic reports and digital datasets provide important statewide, up-to-date geologic information for mineral exploration companies and state land managers regarding the potential of Alaska land for hosting mineral resources. This contribution has been shown to directly influence industry investment decisions and exploration success in Alaska, and to increase state revenue. Additionally, the annual Alaska`s Mineral Industry report provides an accurate record of industry activity and economic statistics relevant to a broad user base including legislators, industry, and investors. The sharp increase in the number of mineral-resource geology reports and datasets in FY2014-16 reflects strong state investment in Critical Minerals Capital Improvement Project appropriations. Output again increased in FY2019 with implementation of the federal Earth MRI program for statewide critical-minerals-related geophysical and geologic mapping. Mineral Resources Section publications in FY2025 included three geophysical surveys, six Raw Data Files, a set of two geologic maps, and an updated map of mineral resource locations in Alaska. A future challenge for this section may include a decrease in Earth MRI funding expected with the expiration of the Infrastructure Investment and Jobs Act (IIJA) in FY2027 (federal fiscal year 2026).

Target #3: Attract maximum industry investment in mineral exploration in Alaska for each state dollar spent on mineral resource assessment. Methodology: Mineral industry exploration investment for the calendar year divided by the division`s expenditure on mineral resource assessment during the previous fiscal year. This measure lags behind by one year because it relies on data for the full calendar year. Industry Exploration Dollars Spent per State Dollar Spent on Mineral Resource Assessment Year Industry Exploration $M DGGS Minerals Spent $M Industry $ per State $ Target 2025 215.0 1.548 138.9 100 2024 220.0 0.984 223.6 100 2023 305.8 1.525 200.5 100 2022 273.1 1.370 199.3 100 2021 145.9 1.217 119.9 100 2020 171.0 0.707 241.9 100 2019 140.1 1.185 118.2 100 2018 120.8 0.735 164.35 100 2017 58.9 1.152 51.13 100 2016 58.3 1.907 30.57 100 2015 96.0 1.858 51.67 50 2014 96.2 4.999 19.2 100 2013 175.5 3.454 50.81 100 2012 355.1 4.002 88.73 100 2011 365.1 2.346 155.63 100 2010 264.4 1.596 165.66 100 Analysis of results and challenges: A primary goal of the Division of Geological & Geophysical Surveys` (DGGS) Airborne Geophysical/Geological Mineral Inventory program is to attract private exploration investment to Alaska. Although many factors influence industry investment decisions, public availability of detailed, reliable geological and geophysical data is an enormous attraction, as these data help to accelerate exploration and significantly reduce exploration risk. Comparison of industry exploration expenditures to state investment in mineral-assessment and knowledge transfer provide a means to evaluate the effectiveness of DGGS minerals work. Based on DGGS` annual mineral industry reports, return on investment has exceeded our target of 100 industry exploration dollars for every state dollar spent since 2017, corresponding with significant progress in data coverage due to Earth MRI funding. Future federal Earth MRI funding may be reduced due to expiration of temporary program increases from the Infrastructure Investment and Jobs Act (IIJA).

A3: Core Service - Geologic hazards information is produced in areas at risk of casualties, economic losses, and infrastructure failure from natural disasters.

Target #1: Publish reports or maps providing improved assessment of geologic hazards that could pose significant risks to public safety or infrastructure. Methodology: Number of peer-reviewed reports or maps published during the fiscal year assessing geologic hazards that pose significant risks to public safety. Published New Reports on Geologic Hazards that Pose Significant Risks to Public Safety Fiscal Year Fiscal Year Total Target FY 2025 44 25 FY 2024 41 25 FY 2023 18 34 FY 2022 30 34 FY 2021 32 34 FY 2020 40 34 FY 2019 31 18 FY 2018 32 12 FY 2017 16 12 FY 2016 18 16 FY 2015 18 12 FY 2014 12 16 FY 2013 13 18 FY 2012 12 12 FY 2011 9 5 FY 2010 4 4 Analysis of results and challenges: Preventing economic losses and reducing threats to public safety from natural disasters is closely tied to our understanding of the risks presented by Alaska`s geology. Mitigation of these risks can only come about through detailed geologic investigations that increase our understanding of natural hazards, and timely distribution of that information. Growing population and increasing development in Alaska create significant demands for acquiring new geologic data and distributing it in a timely fashion. The Division of Geological & Geophysical Surveys` (DGGS) Geologic Hazards Section published 30 hazards-related reports and datasets in FY2025, including nine lidar datasets, eight ortho-images with an accompanying photogrammetry-derived elevation dataset, two coastal hazards flood impact assessments (for the communities of Deering and Kwigillingok), one tsunami inundation report (False Pass), nine landslide hazard studies, and one information circular on landslide hazards. The Hydrology and Surficial Geology Section published 11 hazards-related reports in FY2025, including one poster and one report on debris flow assessment of the Sitka area, two reports from Arctic Strategic Transportation and Resources project work (including data from field investigations in the eastern NPRA southwest of Nuiqsut and geophysical data along a portion of the proposed Triangle Road near Utqiagvik), and four reports associated with geologic mapping and debris flow investigations in Haines. The section also published two surficial geologic maps near Kivalina and the Council Bluff area on the Seward Peninsula, as well as a report on paleoecology (Tofty mining district). The Volcanology Section, working in conjunction with federal U.S. Geological Survey (USGS) and University of Alaska Fairbanks partners, published three volcano-hazard related reports and datasets in FY2025, including a dataset of previously unpublished whole-rock analyses from Alaska volcanoes, an information circular about Mount Spurr, and a techniques and methods paper for glass laser-ablation-inductively coupled plasma-mass spectrometry analysis methods for tephra studies.

Mitigation of these risks can only come about through detailed field mapping and understanding of the natural hazards and processes, and timely distribution of that information to emergency planners, the government, and the public. The survey`s capacity to conduct geologic hazards assessments continues to be greatly enhanced by its ability to collect, process, and interpret high-resolution Light Detection and Ranging (lidar) elevation data. During FY2025, Division of Geological & Geophysical Surveys` (DGGS) Geologic Hazards Section staff responded to more than 175 agency and community requests for assessment of geologic hazards. Some of the most significant activities included continued multi-agency fieldwork at the Barry Arm landslide for environmental monitoring, characterization, and assessment; coordinated support for Shishmaref bathymetric data collection; and continued landslide and surficial mapping for Wrangell debris-flow studies. Most requested assessments were over smaller, targeted areas prone to landslides, eroding bluffs, and flooding, or related to tsunami inundation concerns. During FY2025, Hydrology and Surficial Geology Section staff responded to over 50 requests from agencies and communities for surficial geologic hazards and hydrologic information. Highlights of some of the critical work conducted by the section include collecting, compiling, and evaluating data in a 508 sq. mi. area as part of the West Susitna STATEMAP geologic mapping project, which included 14 days of helicopter-supported fieldwork. The field area encompasses portions of a critical proposed access corridor on the north side of Cook Inlet west of the Parks Highway. Members of the Arctic Strategic Transportation and Resources (ASTAR) team conducted maintenance and downloaded hydrologic data, generally between Utqiagvik and Atqasuk, in close proximity to the ~770 sq. mi. proposed Triangle Road corridor. The section processed an additional 200 sq. mi. of lidar data across the state, supporting many of the division`s geologic hazards investigations. In response to widespread community concerns, the Volcanology Section published an Information Circular about Mount Spurr volcano, covering its monitoring, recent eruptive history, and hazards. This circular was a widely distributed resource to Alaskans as the Alaska Volcano Observatory worked to educate and inform southcentral Alaska residents about unrest at Mount Spurr, possible hazards, and mitigation steps. The Volcanology Section also published hundreds of whole-rock analyses from 16 volcanoes in support of facilitating ongoing research to better understand and characterize Alaska volcano processes and eruptive hazards.

Target #1: Store and distribute digital geologic information that effectively and efficiently meets the needs of industry, government, academia, and the public. Methodology: Volume (in terabytes) of digital geologic data and information distributed. Volume (in terabytes) of Digital Geologic Data Distributed Fiscal Year Fiscal Year Total Target FY 2026 35.0 FY 2025 38.05 30.0 FY 2024 36.49 25.0 FY 2023 25.97 25.0 FY 2022 21.1 25.0 FY 2021 29.51 22.5 FY 2020 32.71 20.0 FY 2019 20.17 17.5 FY 2018 23.87 15.0 FY 2017 7.59 5.0 FY 2016 2.08 4.0 FY 2015 4.85 3.0 Analysis of results and challenges: The Division of Geological & Geophysical Surveys` (DGGS) Geologic Information Center (GIC) maintains and archives more than 1 petabyte (1 PB = 1,000 terabytes, TB) of digital geologic data. The GIC`s IT, GIS, and publication services support the division`s staff in collecting, analyzing, and creating geologic products and web services such as technical reports, geological maps and datasets, geophysical surveys, elevation, and imagery data, as well as other informational publications. This wide range of geologic information is shared as interactive web pages, digital file downloads, geospatial data services, and interactive web applications, all of which are accessible from the division`s website and/or on one of our geoportals (DGGS Geoportal, Elevation Portal, and Imagery Portal). The Alaska Geospatial Office (AGO) administers the State Open Data Geoportal and leads strategic coordination of statewide imagery and lidar (elevation data) acquisition in partnership with federal agencies. In FY2025, the Geoportal experienced a 9% increase in users, growing from 47,000 in FY2024 to 51,000 in FY2025, demonstrating the platform`s increasing value as Alaska`s central hub for authoritative geospatial data. AGO`s statewide imagery basemap had a slight increase in usage, receiving data requests from a total of 176,000 users in FY2025. AGO coordinated the acquisition of 22,000 square miles of lidar with 4,750 sq. mi. of data delivered during FY2025. During FY2025, the division distributed 38.05 terabytes of digital geologic data and information to industry, government, academia, and the public via our DGGS website and/or geoportals. Not counted in this statistic are more than 26,000 publications found by users in FY2025 from the search queries in the multi-agency Alaska Volcano Observatory`s online bibliographic database.

Regardless of the amount of information gathered, the distribution of that knowledge to those who need it is key to providing the desired outcome. The Energy group fielded a normal number of requests for information on conventional oil and gas geology data; however, there was increased interest in carbon sequestration and geologic hydrogen as these industries draw commercial interest. There was notable growth in requests for information about geothermal energy potential in Alaska, reflecting DGGS` new program in this area. The Mineral Resources Section continued to receive numerous requests for Alaska geophysical, geological, and mineral-resource-potential guidance. The Hydrology and Surficial Geology Section received a variety of inquiries, most commonly about the Arctic Strategic Transportation and Resources project, but with the hiring of two Hydrology staff there have been more requests for information about hydrology and hydropower-related issues, especially in the Bristol Bay region. The continued large numbers of requests in FY2025 were driven by increased interest in and division response to geologic hazards, requests for publications and online datasets, and inquiries to the Geologic Materials Center about available samples, tax credit seismic data, and donation offers. The Alaska Volcano Observatory routinely responds to questions from the public regarding volcanic activity, with frequent emails and social media requests asking questions about the substantial volcanic unrest at Mount Spurr during late 2024 through spring 2025. The Geologic Hazards Section received numerous requests for hazards-related information regarding recent landslides, bluff stability, coastal and outburst flooding, tsunami inundation, and 900 requests for radon information and/or radon test kit distribution. The Alaska Division of Geological & Geophysical Surveys is committed to providing a timely response to all requests for geologic information.

Target #2: Deliver public presentations about geologic resources and hazards in Alaska, including technical talks and information displays at conferences, speaking at or teaching classes, and speaking at public meetings. Methodology: Number presentations by division staff during the fiscal year about geologic resources and hazards in Alaska, at technical conferences, classes, public forums, or preparing and being present at public displays. Public Presentations on Geologic Resources and Hazards in Alaska Fiscal Year Fiscal Year Total Target FY 2026 175 FY 2025 197 150 FY 2024 198 100 FY 2023 136 100 FY 2022 91 100 FY 2021 86 125 FY 2020 141 125 FY 2019 163 100 FY 2018 146 100 FY 2017 152 40 FY 2016 53 40 FY 2015 69 40 FY 2014 82 40 FY 2013 45 40 FY 2012 78 20 FY 2011 63 20 FY 2010 49 20 Analysis of results and challenges: Public awareness and knowledge of the Alaska Division of Geological & Geophysical Surveys` (DGGS) geologic work and data archive are paramount to success of the organization`s mission. Although the website and distribution of hard-copy publications are important, the power of staff presence at public forums cannot be underestimated. Local and national technical conferences and public forums often provide the most cost-effective and timely method of disseminating new geologic findings about geologic resources and hazards in Alaska to the broadest audience of end-users. The division dedicates significant effort to this method of knowledge transfer, which is followed up by formal publication of data and interpretations. The division presents geologic knowledge in a wide range of other important public venues, including schools, trade shows, and community meetings. Likely due to rekindled industry activity and public meeting opportunities after the COVID-19 pandemic, the survey provided much greater numbers of public presentations in FY2023 through FY2025. In support of the Governor`s focus on community resilience, DGGS continued to emphasize public awareness of geologic hazards through targeted outreach to support mitigation planning and resilience to earthquakes, tsunamis, avalanches, volcanic eruptions, landslides, coastal erosion and inundation, permafrost, snow and ice, and mineral-related hazards. Several presentations and core workshops, well attended by the oil and gas industry, were led by the DGGS Energy Resources Section. The new geothermal energy program actively engaged in outreach, including hosting an information booth at a national meeting and participating in a public radio special. The new renewable hydropower program also engaged with the community and presented a new analysis from the Tanana River at a national water resources meeting. The Hydrology and Surficial Geology Section presented information about our Sitka debris flow runout assessment at the American Geophysical Union Conference. Highlights include 128 public presentations by the Geologic Hazards Section, 20 presentations by the Mineral Resources Section, and 31 public tours at the Geologic Materials Center in Anchorage, including industry, academic, legislative, and other visitors. The Volcanology Section recorded 41 AVO Radio episodes that were broadcast on 10 public radio stations across Alaska, and they co-hosted a booth at the Alaska Federation of Natives where they had more than 1,000 conversations with Alaskans about Alaska`s volcanism.

C: Result -MAINTAIN ALASKA`S GEOLOGIC SAMPLE REPOSITORY: Maintain and provide public access to Alaska`s invaluable archive of representative geologic samples from across the state.

Target #1: Accommodate and encourage client visits to the Geologic Materials Center for the purpose of studying rock or sediment samples in the interest of resource exploration or geologic-hazard evaluation. Methodology: Number of user visits to the Geologic Materials Center. Client Visits to the Geologic Materials Center Fiscal Year User Visits Target FY 2026 700 FY 2025 818 700 FY 2024 542 1,000 FY 2023 1,199 700 FY 2022 585 500 FY 2021 402 1,200 FY 2020 1,112 1,200 FY 2019 1,475 1,000 FY 2018 1,358 1,000 FY 2017 1,204 600 FY 2016 768 500 FY 2015 279 300 FY 2014 340 300 FY 2013 315 450 FY 2012 467 450 FY 2011 511 450 FY 2010 424 450 Analysis of results and challenges: A significant amount of effort and capital has been spent over the past 60 years to obtain rock and mineral samples from locations throughout Alaska. Most of these samples are irreplaceable or would be extremely difficult and expensive to re-acquire. There were 818 visits to the Geologic Materials Center (GMC) in FY2025, which exceeded the target of 700. Slight client gains were seen across all energy, minerals, state, federal, and public sectors. GMC staff expect visitation levels to dip to 700 visits for FY2026. Visits associated with critical minerals may increase; however, low oil prices and broader institutional uncertainties could lower visitation levels. Current smaller GMC client service staffing levels may also adversely affect the level of support available to clients.

C1: Core Service - Valuable geologic materials from across the state are archived and preserved in the non-proprietary sample inventory for improved public access in support of resource exploration, land management, and geologic education.

Target #1: Provide efficient, user-friendly online access to the Geologic Materials Center`s sample inventory. Methodology: Unique users accessing the GMC`s online inventory system divided by 10. Public Search Queries Using the GMC Online Inventory Interface Fiscal Year Search Queries Target FY 2026 40,000 FY 2025 48,538 14,000 FY 2024 16,518 12,000 FY 2023 13,687 12,000 FY 2022 11,237 9,000 FY 2021 8,970 8,000 FY 2020 11,878 12,000 FY 2019 14,290 5,000 FY 2018 3,130 50,000 FY 2017 51,602 8,800 FY 2016 5,042 5,000 Analysis of results and challenges: During FY2016, there was a drastic shift in tracking client access to the Geologic Materials Center (GMC) inventory, enabled by the transition from the former, static, file-based inventory and online search to a more modern browser-based inventory search interface. The new database-driven search engine allows users to view real-time details of the nearly 800,000 sample inventory items quickly and easily before visiting the facility. This innovative and complex database and online search engine was developed in-house by Division of Geological & Geophysical Surveys staff and continues to serve user needs and receive positive feedback from industry. The second stage of extensive database and web application enhancements during CY2025 are complete and in use. As a consequence of these updates, user metrics for FY2025 and forward are being collected as "Unique Visitors" instead of "User Sessions." There were 485,385 unique visitors to the online GMC inventory interface in FY2025. Similar counts are expected for FY2026, while the GMC also focuses efforts on improved client usability and integration of hyperspectral core scanning datasets into the GMC inventory system.

Target #2: Track demand for viewing the Geologic Materials Center`s sample collection. Methodology: Count the number of sample boxes pulled and viewed by GMC visitors. Sample Boxes Viewed by Visitors Year Boxes Viewed Target 2026 3,750 2025 4,396 3,500 2024 3,729 3,500 2023 3,562 5,000 2022 4,928 2,000 2020 4,001 2,250 2019 2,898 2,000 2018 2,019 2,100 2017 2,088 2,250 2016 2,457 2,500 Analysis of results and challenges: One goal of the Geologic Materials Center (GMC) is to encourage and support industry, government, and academia in their efforts to expand the framework of geologic knowledge of Alaska. To gauge direct client interest in the GMC inventory, the division started tracking sample boxes pulled for client viewing or sampling in 2015. GMC staff reported 4,396 sample boxes were requested by clients in FY2025. Energy industry geologists returned to examine and sample legacy core and held multiple large core workshops. This year`s sample box request is the second highest in ten years of operation at the Anchorage facility. Current smaller GMC client service staffing levels, lower petroleum prices, and other uncertainties may adversely affect sample requests over the next fiscal year. Target Last Modified: 10/10/2025
