Thule Inuit environmental impacts on Kangeq, southwest Greenland

摘要

Palaeoecological investigations of a rapidly eroding coastal midden and an adjacent peat bog on the island of Kangeq in southwest Greenland have provided new information on environmental change and human impact associated with Thule Inuit occupation. Palynological and palaeoentomological datasets have been produced through the 14th to the 17th centuries AD. The pollen and sedimentary data provide evidence for peat formation, increased frequency of the northern annual herb Koenigia islandica (Iceland purslane) from the end of the 15th century AD, and a decline in shrub pollen over the same period. These changes are interpreted as local responses to Little Ice Age cooling. No clear signal for human impact on the vegetation was revealed in the pollen record, and there was little macroscopic charcoal recovered from either of the sedimentary contexts that were examined; microscopic charcoal evident in the peat column is probably evidence for domestic fires. The insect remains suggest periodic patterns of disposal on the midden and provide information on natural environments in the vicinity. Fossil fly puparia (Diptera) are associated with decaying animal materials and perhaps indicate waste produced from the skinning of marine mammals and birds as opposed to butchering. The faunas contrast with results from the Saqqaq site of Qeqertasussuk and several Norse farms.
