Marine Isotope Stage - Stages

Stages

The following are the start dates of the most recent MIS, in kya (thousands of years ago). The first figures are derived by Aitken & Stokes from Bassinot et al. (1994), with the figures in parentheses alternative estimates from Martinson et al. for stage 4 and for the others the SPECMAP figures in Imbrie et al. (1984). For stages 1–16 the SPECMAP figures are within 5 kya of the figures given here. All figures up to MIS 21 are taken from Aitken & Stokes, Table 1.4, except for the sub-stages of MIS 5, which are from Wright's Table 1.1.

  • MIS 1 - 11 kya, end of the Younger Dryas marks the start of the Holocene, continuing to the present
  • MIS 2 - 24 near Last Glacial Maximum
  • MIS 3 - 60
  • MIS 4 - 71 (74)
  • MIS 5 - 130, includes the Eemian; usually sub-divided into a to e:
    • MIS 5a - 84.74
    • MIS 5b - 92.84
    • MIS 5c - 105.92
    • MIS 5d - 115.105
    • MIS 5e - 130.115
  • MIS 6 - 190
  • MIS 7 - 244
  • MIS 8 - 301
  • MIS 9 - 334
  • MIS 10 - 364
  • MIS 11 427, the most similar to MIS 1.
  • MIS 12 - 474
  • MIS 13 - 528
  • MIS 14 - 568
  • MIS 15 - 621
  • MIS 16 - 659
  • MIS 17 - 712 (689)
  • MIS 18 - 760 (726)
  • MIS 19 - 787 (736)
  • MIS 20 - 810 (763)
  • MIS 21 - 865 (790)

Some older stages, in mya (millions of years ago):

  • MIS 22 - 1.03 mya, marking the end of the Bavelian period in Europe
  • MIS 62 - 1.75, end of the Tiglian
  • MIS 103 - 2.588, end of the Pliocene and start of the Pleistocene, on the INQUA time scale (older definitions put this change at 1.806 mya - the MIS date is unaffected)

Famous quotes containing the word stages:

    “America is a country that seems forever to be toddler or teenager, at those two stages of human development characterized by conflict between autonomy and security.”
    —Anna Quindlen (b. 1952)

    “But parents can be understanding and accept the more difficult stages as necessary times of growth for the child. Parents can appreciate the fact that these phases are not easy for the child to live through either; rapid growth times are hard on a child. Perhaps it’s a small comfort to know that the harder-to-live-with stages do alternate with the calmer times,so parents can count on getting periodic breaks.”
    —Saf Lerman (20th century)

    “Whoe’er has travelled life’s dull round,
    Where’er his stages may have been,
    May sigh to think he still has found
    The warmest welcome, at an inn.”
    —William Shenstone (1714–1763)
