Significance of Labrador Sea and Baffin Bay Waters for growth of the Laurentide Ice Sheet
Global ice-sheet growth from interglacial stage 5e to last glacial maximum stage 2 occurred in two major steps, at the isotope stage 5e/5d and 5a/4 transitions (e.g., Ruddiman et al. 1980). Although we do not know where ice accumulated during these times of increasing oceanic 8’0, one likely locatio...
