Alaska Pipeline

Prudhoe Bay to Fairbanks, Alaska

Alaska Pipeline

Hart Crowser assessed potential effects of a proposed natural gas pipeline on anadromous and resident fish, wetlands, streambank stability, and water quality along a 500-mile route from Prudhoe Bay to Fairbanks. Work along the pipeline right-of-way included habitat surveys, electrofishing, stream geomorphology assessment, and water measurements. Extensive field work in remote locations was necessary in order to access the right of way. The work was compiled into an interactive database for use by the design team and for submission to state and federal regulators. Our biologists used a van Veen grab sampler, CTD profiler, otter trawl, and vibracore sampler in order to characterize sediment chemistry and geotechnical qualities, water quality, benthic infauna, and demersal fish and invertebrate assemblages along the proposed dredging corridor and inwater docking facilities.
