This project entails the design of an interactive workshop to share erosion monitoring strategies with participants from at least seven Bristol Bay communities. The training opportunity will heighten the scientific capacity of the Bristol Bay region by enabling residents to use low-cost time-lapse camera systems in conjunction with survey stakes to collect quantitative measurements of coastal, river, and/or lake erosion. This technique combines existing methodologies of erosion monitoring in a new and innovative way to transform anecdotal reports of erosion into rigorous measurements that will create a quantitative record of shoreline change.


The issue

Despite the need for information to fuel decision-making in a changing environment, Alaska’s extensive
shorelines are inconsistently monitored and under-instrumented for the evaluation of coastal erosion. Alaska's local residents have the necessary local knowledge, motivation, and ability to help quantify rates of erosion in remote areas.

Why is this an Alaska Sea Grant project?

Alaska Sea Grant is dedicated to building resilient communities and economies through science extension that educates, engages, and supports residents. This project embraces the Sea Grant mission to enhance the wise use of Alaska's coastal resources by employing education and outreach to enable community residents to lead local, scientifically sound erosion monitoring efforts that will improve Alaska's ability to adapt to coastal hazards and environmental change.
