An 8500cal. year multi-proxy climate record from a bog in eastern Newfoundland: contributions of meltwater discharge and solar forcing
Analyses of plant macrofossils, testate amoebae and the degree of peat humification have been combined into a single composite reconstruction of bog surface wetness (BSW) on a coastal plateau bog in eastern Newfoundland. The reconstruction reveals 14 distinctive phases of near-surface water tables c...
