New Marine Sediment Core Data Support Holocene Stability of the Larsen B Ice Shelf
Summary Multi-proxy data (sedimentologic, geochemical and micropaleontologic) from 10 kasten cores collected from within the Larsen B embayment during two research cruises, LMG0502 and NBP0603, support earlier data indicating that the March 2002 collapse of the Larsen B Ice Shelf was a unique event...

| Summary: | Summary Multi-proxy data (sedimentologic, geochemical and micropaleontologic) from 10 kasten cores collected from within the Larsen B embayment during two research cruises, LMG0502 and NBP0603, support earlier data indicating that the March 2002 collapse of the Larsen B Ice Shelf was a unique event and that the ice shelf had been present since its formation at the end of the last glacial period. Chronologies for these cores have been developed through a combination of radiocarbon and 210Pb analyses. In general, the sediment core data illustrate the transition from grounded ice to a sub-ice shelf setting, followed by the open marine environment present today. More details regarding processes associated with ice shelf collapse are recorded as well, including rapid deposition in sites |
