The late Quaternary environmental evolution of the Northwest Passage: a marine perspective

Abstract

Here we present direct marine data from three long (piston and trigger weight) sediment cores from the central Northwest Passage (Lancaster Sound/Barrow Strait: core 86027-154; southeastern Barrow Strait: 86027-144; western Barrow Strait: 9722-004), investigated in a multiproxy approach for sedimentological characteristics, microfossils (dinocysts, non-pollen palynomorphs, benthic and planktonic foraminifera, ostracods), and stable isotope ratios.
