Evidence from the Ross embayment, Antarctica, suggests an abrupt cooling and a concomitant increase in sea-ice cover at about 6000 BP (6 ka). Stable-isotope (tSD) concentrations in the Taylor Dome ice core, at the western edge of the Ross embay­ment, decline rapidly after 6 ka, and continue to decli...
