摘要

How is sediment transported to the seafloor along coastlines where the sea ice rarely melts? Are there distinctive characteristics of the resulting deposits that label them as accumulating in this setting that is so sensitive to climate change? Our project-aimed at determining the sedimentary, bioturbation, and taphomomic (fossilization) processes in Explorers Cove, Antarctica (Figure 1), and characterizing the resulting sedimentary record-depends on material collected by divers who descend through holes melted through the sea ice.
