dc.descriptionAbstract: Hubbard Glacier, near Yakutat, Alaska, is the largest non-polar tidewater glacier in the world. In contrast to most glaciers in southeast Alaska, Hubbard Glacier continues to advance and has thickened at an average rate of 35 m yr⁻¹. Twice since 1986 Hubbard Glacier has advanced enough to cause a temporary closure of Russell Fiord. If Hubbard Glacier continues to advance, a permanent closure of Russell Fiord would ultimately cause significant damage to the town of Yakutat and the economic fisheries that sustain it. This report presents the results of a first-of-its-kind survey of the submarine and terrestrial environment of the Hubbard Glacier tidewater terminus and the area surrounding Gilbert Point. High-resolution, multibeam bathymetry and current velocity profiles, combined with simultaneously acquired high-resolution LiDAR topography, provide a detailed look at the section of the glacier where ice damming of Russell Fiord is likely to occur.-
