Introduction<\/p>\n
The NASA Arctic\u2013Boreal Vulnerability Experiment<\/a> (ABoVE) is a large-scale ecological study in the northern regions of North America (Alaska and western Canada) that was developed to understand environmental changes in the region and the implications of those changes for society. Funded primarily by the NASA Terrestrial Ecology Program, this 10-year campaign has included field, airborne, and satellite remote sensing research to address its overarching scientific question of how environmental change in the Arctic and boreal region of western North America will affect vulnerable ecosystems and society.<\/p>\n ABoVE deployed in three phases: 1) ecosystem dynamics (2015\u20132018); 2) ecosystem services (2017\u20132022); and 3) analysis and synthesis (2023\u2013present). Now in the last year of the third phase, the Science Team (ST) consists of 67 active NASA-funded projects with more than 1000 individuals participating. The ABoVE ST has met yearly to discuss the progress of individual teams, plan joint field work, and discuss synthesis activities. ABoVE was featured in a 2019 The Earth Observer article, titled \u201cSummary of the 2019 ABoVE Science Team Meeting<\/a>\u201d [July\u2013August 2019, Volume 31, Issue 4, pp. 19\u201322], as well as a 2022 The Earth Observer article, titled \u201cSummary of the Eighth ABoVE Science Team Meeting<\/a>\u201d [September\u2013October 2022, Volume 34, Issue 5, pp. 28\u201333].<\/p>\n Meeting Overview<\/p>\n The 11th \u2013 and final \u2013 ABoVE Science Team Meeting (ASTM11) was held May 12\u201315, 2025, with 96 registered in-person attendees meeting at the University of Alaska, Fairbanks (UAF) and 67 registered virtual attendees \u2013 see Photo 1. The meeting included presentations from Phase 3 projects and synthesis reports from thematic working groups (WGs). ABoVE partners, including collaborators [e.g., the Department of Energy\u2019s Next Generation Ecosystem Experiment-Arctic<\/a> (NGEE-Arctic), Polar Knowledge Canada<\/a> (POLAR), the Canadian Forest Service (CFS), and the Government of the Northwest Territories (GNWT)] and representatives from upcoming NASA campaigns focusing on the Arctic, shared updates on their activities. Additionally, the meeting featured sessions highlighting cross-project activities, e.g., ABoVE\u2019s participation in regional fire workshops. The meeting also focused on collaborations with the Scotty Creek Research Station<\/a> in Canada, the many types of science communication activities during ABoVE, and projects conducting collaborative research with community or regional partners.<\/p>\n The meeting included additional team activities designed to encourage collaboration and understanding between team members. There were opportunities for multiple field trips for in-person attendees, including visits to the Alaska Satellite Facility<\/a> (ASF) at the Geophysical Institute, the Permafrost Tunnel operated by the Cold Regions Research and Engineering Laboratory<\/a> (CRREL), the Yankovich Road Fire Interpretive Trail<\/a>, and the Arctic Research Open House at UAF \u2013 see ABove Field Trips section to learn more. The meeting offered early career researchers a chance to receive feedback on their posters and participate in an Early Career lunch event. The meeting even hosted an ABoVE bingo competition, which encouraged attendees to make new scientific and social connections \u2013 see Photo 2.<\/p>\n Meeting Opening <\/p>\n The first day of the meeting began with a series of opening remarks from the ABoVE leadership team. Peter Griffith [NASA\u2019s Goddard Space Flight Center (GSFC)\/Science Systems and Applications, Inc. (SSAI)\u2014Chief Scientist, Carbon Cycle and Ecosystems Office (CCEO)], Scott Goetz [Northern Arizona University (NAU)\u2014ABoVE ST Lead], and Ryan Pavlick [NASA Headquarters (HQ)\u2014ABoVE Program Manager] all noted the significance of this final meeting and discussed the major scientific advances of ABoVE made possible through the dedication of ST members, WG leads, planning committees, and contributors who have made ABoVE a success. Goetz reviewed the meeting goals and objectives:<\/p>\n receive updates about currently funded projects;<\/p>\n receive reports on Thematic WG advances with an emphasis on multiple WG and cross-phase synthesis activities;<\/p>\n receive updates on research connections with partners and collaborators;<\/p>\n discuss, reflect, and document the history of ABoVE, including major advances, lessons learned, and items to accomplish in the time remaining; and<\/p>\n celebrate ABoVE success stories, with advice for potential future NASA large-scale coordinated campaigns.<\/p>\n Working Group Presentations and Breakouts<\/p>\n Throughout the first few days of the meeting, leads for the thematic working groups (WG) presented synthetic overviews of the research efforts of their group members, identified current gaps in planned or completed research, and discussed potential future work. Following these presentations, breakout groups convened to discuss future activities of the WGs. Short summaries of each presentation are available below. Together, these presentations demonstrate the highly interconnected nature of carbon cycles, hydrology, permafrost dynamics, and disturbance regimes in Arctic\u2013boreal ecosystems. The presentations also showcase the substantial ongoing WG efforts to synthesize findings and identify critical knowledge gaps for future research priorities.<\/p>\n Vegetation Dynamics Working Group<\/p>\n WG Leads: Matthew Macander [Alaska Biological Research, Inc. (ABR)] and Paul Montesano [GSFC\/ADNET Systems Inc.]<\/p>\n The Vegetation Dynamics WG discussed new advances in understanding Arctic\u2013boreal vegetation structure and function that have been made over the past 10 years through comprehensive biomass maps and multidecadal trend analyses. ABoVE research revealed a critical boreal forest biome shift with greening in nitrogen-rich northern forests and browning in drought-stressed southern forests. The group has identified key knowledge gaps in predicting post-fire vegetation recovery and detecting pervasive declines in vegetation resilience across southern boreal forests. The results suggest higher vulnerability to abrupt forest loss that could dampen the expected increase in carbon sequestration under future climate scenarios.<\/p>\n Spectral Imaging Working Group<\/p>\n WG Leads: Fred Huemmrich [GSFC\/University of Maryland Baltimore County] and Peter Nelson [Laboratory of Ecological Spectroscopy<\/a> (LECOSPEC)]<\/p>\n Over the past year, the Spectral Imaging WG focused on the fundamental scale problem in Arctic ecology, which refers to the mismatch between observation scales and ecological process scales, which span spatial scales from leaf level to larger study areas and temporal scales from minutes to decades. The Airborne Visible\/Infrared Imaging Spectrometer – Next Generation <\/a>(AVIRIS-NG) and AVIRIS-3<\/a> datasets provide the first broad-area and high-spatial and spectral resolution coverage of high-latitude terrestrial ecosystems. The WG is now completing a scaling synthesis paper and preparing for the new era of data-rich spectral imaging with improved capabilities in data management, machine learning, and modeling applications for high-latitude research.<\/p>\n Modeling Working Group<\/p>\n WG Lead: Josh Fisher [Chapman University]<\/p>\n The Modeling WG aims to reduce model uncertainties in simulations and projections in the Arctic\u2013boreal region across all ABoVE ecosystem indicators. The WG had polled the ST to determine the variables most needed for their Earth system models and is now using the field, airborne, and satellite datasets to better constrain these models. This WG discussed the benefits to the modeling community of transforming the more than 100 ABoVE datasets into a common grid and projection format used by modelers.<\/p>\n Carbon Dynamics Working Group<\/p>\n WG Leads: Jonathan Wang [University of Utah] and Jennifer Watts [Woodwell Climate Research Center<\/a> (WCRC)]<\/p>\n The Carbon Dynamics WG has focused its recent work on three areas: decadal syntheses of carbon dioxide (CO2) fluxes from eddy covariance towers, machine learning approaches to upscaling wetland and lake methane (CH4) emissions, and carbon flux modeling across the Arctic\u2013boreal zone. The research integrated atmospheric CO2 observations to improve carbon flux estimates and examined wildfire impacts on both carbon emissions and albedo changes. A significant component of the work involved comparing top-down versus bottom-up carbon flux models, with particular attention to permafrost and peatland regions.<\/p>\n Hydrology-Permafrost-Wetlands Working Group<\/p>\n WG Leads: Laura Bourgeau-Chavez [Michigan Technological University], David Butman [University of Washington], John Kimball [University of Montana], and Melissa Schwab [University of California, Irvine]<\/p>\n The Hydrology\u2013Permafrost\u2013Wetlands WG focused on the processes controlling changes in permafrost distribution and properties and their impacts. There was discussion about the nature, causes, and consequences of hydrologic change (e.g. water storage, mobility, and distribution) and about ecosystem water, energy, and carbon cycle linkages. The presenters mentioned integration of ABoVE datasets with NASA satellite missions [e.g., NASA\u2013Indian Space Research Organisation (ISRO) Synthetic Aperture Radar<\/a> (NISAR) and Surface Water and Ocean Topography <\/a>(SWOT)]. WG members discussed the connections between ABoVE research and several crosscutting initiatives, including two NASA Arctic coastlines efforts [e.g., Frontlines Of Rapidly Transforming Ecosystems Earth Venture Suborbital<\/a> (FORTE EVS) campaign and NASA\u2019s Arctic-COastal Land Ocean inteRactionS <\/a>(COLORS)] and the WCRC\u2019s Permafrost Pathways<\/a>.<\/p>\n Disturbance Working Group<\/p>\n WG Leads: Dong Chen [University of Maryland, College Park] and Jinhyuk Kim [University of California, Irvine]<\/p>\n The Disturbance WG leads presented their decade-long perspective on disturbance-related research in the ABoVE domain. The presentation incorporated artificial intelligence (AI)-generated summaries of ABoVE-affiliated research across multiple disturbance types, including boreal wildfires, tundra wildfires, and thermokarst\/permafrost degradation processes. Chen and Kim acknowledged the extensive contributions from researchers and WG members while outlining future directions for disturbance research.<\/p>\n Success Stories<\/p>\n Four \u201cSuccess Story\u201d presentations and panels took place during ASTM11, which showcased efforts of ABoVE ST members and the leadership team to create and coordinate engagement efforts that spanned individual projects.<\/p>\n Success Story 1: ABoVE Participation in Regional Fire Workshops<\/p>\n A substantial portion of ABoVE research has focused on wildfire, and many members of the ST have participated in domestic and international wildfire efforts, connecting researchers with land managers across Alaska and Canada. Randi Jandt [UAF] discussed the Alaska Fire Science Consortium<\/a> workshops (held in 2017<\/a> and 2022<\/a>). Jenn Baltzer [Wilfred Laurier University (WLU), Canada] discussed Northwest Territories workshops (held in 2014<\/a> and 2025<\/a>), both of which occurred in response to extreme fire seasons in the region. Laura Bourgeau-Chavez outlined ABoVE\u2019s participation in all of these workshops. The workshops facilitated knowledge exchange and collaboration on critical wildfire management priorities, including fire risk assessment, real-time modeling, post-fire effects, and climate change impacts on fire regimes. Key features included small focus groups, field trips to command centers and fire-affected areas, and integration of Indigenous knowledge with new technologies to inform management practices and climate preparedness strategies.<\/p>\n Success Story 2: Collaborations with Scotty Creek Research Station (SCRS)<\/p>\n ASTM11 participants watched the film, \u201cScotty Creek Research Community – The Spirit of Collaboration<\/a>,\u201d about the SCRS, Canada\u2019s first and only Indigenous-led research station. Following the film, station team members participated in a panel discussion. Ramona Pearson [Ramona Pearson Consulting, Canada], Maude Auclair [WLU], Mason Dominico [WLU], Michael McPhee [Sambaa K’e First Nation, Canada], and William \u201cBill\u201d Quinton [WLU] discussed their decade-long collaboration with ABoVE. The partnership involved ABoVE collecting airborne hyperspectral, lidar, and radar imagery, while SCRS researchers provided field data for calibration and validation. In 2022, management of the station transitioned to \u0141\u0131\u0301\u0131\u0301dl\u0131\u0328\u0131\u0328 K\u0173\u0301\u0119\u0301 First Nation (LKFN, Canada), and ABoVE continued collaborating through knowledge exchange, including with early-career researchers and interns. When a 2022 fire destroyed the field station and surrounding area, ABoVE flew additional flights to capture airborne imagery observations to allow comparison of pre- and post-fire conditions.<\/p>\n Success Story 3: Science Communication<\/p>\n During the ABoVE field campaign, ST members and CCEO staff engaged in multiple strategies to communicate research results to the public. The activities included interactive engagement through airborne open houses and guest flights, ST member narratives in the \u201cNotes from the Field<\/a>\u201d blog posts on the NASA Earth Observatory<\/a> website, and professional multimedia production, including Earth Observatory content and award-winning videos<\/a>. This multifaceted strategy demonstrates effective scientific communication through direct public engagement and high-quality, multimedia storytelling, making complex research accessible to diverse audiences.<\/p>\n Success Story 4: Engagement Activities<\/p>\n This session highlighted several examples of community engagement across the ABoVE domain. Gerald \u201cJ.J.\u201d Frost [ABR] discussed synthesizing ecosystem responses and elder observations in western Alaska for his ABoVE project. In another example, ABoVE researchers from Michigan Tech Research Institute<\/a> (MTRI) partnered with Ducks Unlimited Canada<\/a> (DUC) and local organizations. Dana Redhuis [MTRI] and Rebecca Edwards [DUC] described their on-the-land camps<\/a> that provide hands-on training for Northwest Territories youth in wetlands education and ecological monitoring. Kevin Turner [Brock University, Canada] showcased his work with members of the Vuntut Gwitchin First Nation in Old Crow Flats, Yukon, evaluating how climate and land cover change influence water dynamics and carbon balance. These activities demonstrate collaborative research that integrates Indigenous and Western knowledge approaches to address climate change impacts.<\/p>\n ABoVE Phase 3 Project Presentations<\/p>\n Project leads of the 20 NASA-funded ABoVE Phase 3 projects presented updates that were organized by scientific theme.
