... are restricted to one depositional package on the entrance sill. Volumes of LIA retreat sediments were calculated within basins. An average annual sediment flux was calculated by modeling the duration of sediment contributed from Muir Glacier and from tributary glaciers and side-entry sources. The annual...

... sediments, and the history of terminus retreat of Muir Glacier, Glacier Bay, Alaska, we calculate the sediment flux as a function of time from this glacier between 1900 and 1979, and conclude that sediment flux scales with retreat rate. The corresponding basin-wide erosion rate during this 79 yr period...

Magnetic susceptibility values are highest for the sediment accumulating in Muir Inlet, Glacier Bay, exceeding χ values from Disenchantment...

The problems for road construction imposed by difficulties of access and remoteness have been compounded by rockslope instability, debris flows, river and meltwater surges, and fluctuating glacier snouts. As a consequence, the employment of sophisticated engineering techniques...

We recognised that inputs of organic particulates might be important for sustaining the subglacial ecosystem because...

.... In this paleovalley, the glacio-eustatic rise probably caused floating and consequent rapid melting of the valley glacier. This resulted in a paleovalley-wide turbidite event that is up to 5 m thick and indicates an overall waning character. The rapid sediment emplacement in this event and resulting loading...
