Sedimentary Processes in the Fjord-like Embayments of the Vestfold and Larsemann Hills
Progress Code: completed Ellis Fjord is a small, fjord-like marine embayment in the vestfold Hills, eastern Antarctica. Modern sediment input is dominated by a biogenic diatom rain, although aeolian, fluvial, ice-rafted, slumped and tidal sediments also make a minor contribution. In areas where biot...

Progress Code: completed Ellis Fjord is a small, fjord-like marine embayment in the vestfold Hills, eastern Antarctica.

In areas where bioturbation is significant relict glaciogenic sediments are reworked into the fine-grained diatomaceous sediments to produce poorly sorted fine sands and silts.
