  • Palaeoclimate reconstruction on Big Lyakhovsky Island, North Siberia - hydrogen and oxygen isotopes in ice wedges
  • Asian part of Russia ; Deuterium ; Holocene ; Ice wedge ; Isotope analysis ; Oxygen 18 ; Palaeo-environment ; Palaeoclimate ; Periglacial features ; Pleistocene ; Quaternary ; Siberia
  • isotope analyses are presented for 6 different generations of ice wedges as well as for recent ice wedges and precipitation. An age of about 200 ka BP was determined for an autochtonous peat layer in ice-rich deposits by U/Th method, containing the oldest
  • ice wedges ever analysed for hydrogen and oxygen isotopes.

  • Stable isotopes in pocket gopher teeth as evidence of a Late Matuyama climate shift in the southern Rocky Mountains
  • Climatic cycle ; Colorado ; Fossil fauna ; Glaciation ; Isotope analysis ; Palaeo-environment ; Palaeoclimate ; Pleistocene ; Rocky Mountains ; United States of America
  • In this paper, carbon and oxygen stable isotope data of herbivorous rodent teeth are used as indicators of change in the predominance of C3, C4, and CAM plants and of changes in temperature and precipitation. Taken together with other previously

  • C 14 dating ; Carbon ; Holocene ; Isotope analysis ; Lacustrine sediment ; Lake ; Lake level ; Meltwater ; Michigan ; Oxygen 18 ; Palaeo-ecology ; Palaeo-environment ; Pollen diagram ; Precipitation ; United States of America
  • Holocene sediments from Nelson Lake, on Michigan's eastern Upper Peninsula, provide isotopic, pollen, and charcoal evidence for a two-step sequence of changes in moisture source and increased lake-effect precipitation during the late Holocene
