Communities, resource managers, and decision makers in Arctic Alaska are in need of scientific information to base important decisions related to anticipating and adapting to changes in temperature and precipitation. Since its inception in 2011, the Alaska Climate Science Center (AK CSC) and its partners have produced a variety of scientific products and datasets aimed at supporting this need and increasing climate change resilience in the Arctic. However, much of the information related to these activities is dispersed across many technical publications, and is often not readily accessible to those outside the research community. In an effort to make this science more available and accessible, the AK CSC is working...

Communities, state and federal agencies, resource managers, and decision makers throughout Alaska need sound scientific information to better understand our changing world to make informed, science-based decisions that will shape the future. Scientists also need information from these stakeholders to understand what science questions need to be answered, develop research priorities, and gain important insight about the landscape based on personal experiences and generational knowledge. However, effective two-way conversations between scientists and stakeholders are often limited, due to resource constraints, a lack of necessary communication skills and tools, and other factors. A mechanism for better communication...

As temperature and precipitation patterns change in Alaska, the need for scientific information to inform decision making related to the management of our natural resources becomes ever more important. However, the research being conducted to understand potential future impacts of climate change in Alaska frequently results in output and products that, in their raw forms, are not easily used by stakeholders and partners or are somewhat removed from the direct information needs of natural resource decision makers. This project broadly aims to evaluate the information needs of regional stakeholders and partners; conduct “translational” activities to make archived historical data, modeled output, and future projections...
How do glaciers impact Alaska’s coastal ecosystems, and what do glacier changes mean for the future of this ecologically and economically valuable system?
Abstract (from http://onlinelibrary.wiley.com/doi/10.1002/2015JF003539/abstract): A quantitative understanding of snow thickness and snow water equivalent (SWE) on glaciers is essential to a wide range of scientific and resource management topics. However, robust SWE estimates are observationally challenging, in part because SWE can vary abruptly over short distances in complex terrain due to interactions between topography and meteorological processes. In spring 2013, we measured snow accumulation on several glaciers around the Gulf of Alaska using both ground- and helicopter-based ground-penetrating radar surveys, complemented by extensive ground truth observations. We found that SWE can be highly variable (40%...

Permanently frozen ground, known as permafrost, is a critical feature of the Arctic landscape. As temperatures warm, permafrost is thawing, with potentially adverse impacts to infrastructure, communities, and the structure and function of Arctic ecosystems. However, the processes leading to changes in permafrost are not well understood, and there is a need to better understand the vulnerability of permafrost to thaw. Addressing these gaps in information regarding permafrost characteristics and dynamics, and what these changes will mean for human communities and ecosystems, will support management and planning efforts. This project seeks to address these gaps through several mechanisms. First researchers have synthesized...

Changing climate conditions (e.g. changes to air temperature, surface temperature, snowpack duration, and soil temperature) are affecting where trees are able to successfully grow and are bringing changes to the structure of forests throughout many parts of Alaska. In order to understand and project future vegetation changes, scientists use computer models to establish the relationships between climate variables, such as those mentioned above, and ecological responses such as the presence or absence of a tree species, tree growth and establishment, changes in sap flow, and other demographic and physiological responses. These computer models, however, frequently do not account for Alaska’s extreme topography and...
