  • Army engineers promote sustainable construction practices on Last Frontier

    Each year, the U.S. Army Corps of Engineers – Alaska District constructs projects for the military valued in the millions of dollars to support readiness, training and quality-of-life initiatives for service members in the Far North. For each of these endeavors, the agency works to meet sustainability goals by ensuring the construction practices and new facilities are as energy efficient as possible.

  • Sitka woman finds STEM career with Army engineers

    Everyone pursues a career in the fields of science, technology, engineering and math (STEM) for a different reason. Danielle Perkins, Department of the Army apprentice at the U.S. Army Corps of Engineers – Alaska District, followed the footsteps of her dad and grandpas into that sector.

  • Engineers tackle Army Combat Fitness Test in Alaska

    Soldiers with the U.S. Army Corps of Engineers – Alaska District partnered with the 6th Brigade Engineer Battalion to assess their strength and stamina during the Army Combat Fitness Test on Aug. 17 at Joint Base Elmendorf-Richardson, Alaska.

  • Engineers help to improve educational opportunities in Mongolia

    In a country experiencing a shortage of critical educational facilities, the U.S. Army Corps of Engineers – Alaska District is overseeing the design and construction of kindergartens to better the lives of children in Mongolia. Over the last three years, the district has partnered with the U.S. Embassy and U.S. Indo-Pacific Command to improve educational opportunities for more than 300 students throughout Mongolia.

  • Machine Learning Analyses of Remote Sensing Measurements Establish Strong Relationships Between Vegetation and Snow Depth in the Boreal Forest of Interior Alaska

    Abstract: The seasonal snowpack plays a critical role in Arctic and boreal hydrologic and ecologic processes. Though snow depth can be different from one season to another there are repeated relationships between ecotype and snowpack depth. Alterations to the seasonal snowpack, which plays a critical role in regulating wintertime soil thermal conditions, have major ramifications for near-surface permafrost. Therefore, relationships between vegetation and snowpack depth are critical for identifying how present and projected future changes in winter season processes or land cover will affect permafrost. Vegetation and snow cover areal extent can be assessed rapidly over large spatial scales with remote sensing methods, however, measuring snow depth remotely has proven difficult. This makes snow depth–vegetation relationships a potential means of assessing snowpack characteristics. In this study, we combined airborne hyperspectral and LiDAR data with machine learning methods to characterize relationships between ecotype and the end of winter snowpack depth. Our results show hyperspectral measurements account for two thirds or more of the variance in the relationship between ecotype and snow depth. An ensemble analysis of model outputs using hyperspectral and LiDAR measurements yields the strongest relationships between ecotype and snow depth. Our results can be applied across the boreal biome to model the coupling effects between vegetation and snowpack depth.

  • USACE employee celebrates 50 years of federal service

    A member of the U.S. Army Corps of Engineers – Alaska District achieved a unique milestone as a government employee recently. Amy Burke, workforce management specialist, celebrated 50 years of federal service in a ceremony hosted by Col. Damon Delarosa, district commander, at the agency’s headquarters on June 24.

  • Corps approves plan to upgrade Lowell Creek flood diversion project in Seward

    The U.S. Army Corps of Engineers’ Director of Civil Works, Alvin Lee, signed the director’s report that recommends improvements to the Lowell Creek flood diversion project on May 19 in Washington, D.C. This action marks the completion of the Alaska District’s feasibility study and advances the proposed project to Congress for funding consideration.

  • Alaska District wins Army Environmental Award for Second Consecutive Year

    Climbing up the hillside of a remote Alaskan island, an old tramway rusts into the ground beneath it. With gnarled rails, the 2,400-foot structure is a remanent of an abandoned radar facility that provided early warning of approaching enemy aircraft during World War II. The tramway is part of a formerly used defense site that the U.S. Army Corps of Engineers – Alaska District worked to clean up the past two summers.

  • Army engineers celebrate 75 years on the Last Frontier

    Seventy-five years ago today, the Chief of Engineers ordered the establishment of the U.S. Army Corps of Engineers – Alaska District. With the stroke of a pen on General Order No. 6, the agency was born.
