| Summary: | One current hypothesis for the Pleistocene peopling of the Americas invokes a dispersal by European hunter-gatherers along a biologically productive "corridor" situated on the edge of the sea-ice that filled the Atlantic Ocean during the Last Glacial Maximum (LGM). In this paper, we assert that critical palaeoceanographic data underpinning this hypothesis has not yet been examined in sufficient detail. To this end, we present data which show that the corridor may not have existed, and that, if it did, its suitability as a migration route is highly questionable. In addition to demonstrating that the hypothesized migration was unlikely, this highlights the importance of integrating palaeoceanographic and archaeological data in studies of palaeo-coastal societies.
