How We Do It

The ACGL applies high-resolution topographical, geospatial, and sedimentary tools to research coastal processes and hazards occurring over multiple spatial and temporal scales. We develop paleo-proxy records of long-term environmental changes using sediment cores and other geological methods. This provides the necessary context to assess present and future coastal hazard risks. The ACGL also guides an active community based erosion monitoring program that partners with Alaska Native coastal and riverine communities and other local, state, and federal organizations. Data obtained at these sites contributes to coastal hazard assessments and data products that enable local planners to make informed decisions on future development.


We utilize a variety of computer-based geospatial tools to process, interpret, and produce data products and visualizations from field and remotely sensed data. Software packages include ArcGIS, Photoscan, Adobe Illustrator, and Trimble Business Center.


Sediment coring in remote areas of Alaska can be tricky business. Here we are collecting a core from an inflatable raft from a coastal pond along the Chukchi coastline.




We travel to remote field sites on some incredibly small airplanes making every trip a real adventure.


At each field site we collect a variety of baseline geospatial data sets such as high resolution topographic data using a real-time kinematic GPS system. These data provide a precision baseline in which to measure future changes.
