Quaternary global chronostratigraphical correlation table for the last million years. The timescale is based on the internationally-recognised subdivisions of Phanerozoic Eon, Cenozoic Era, Quaternary System or Period; Pleistocene and Holocene Epochs or Series, and finally the Early/Lower, Middle, Late/Upper Pleistocene Subseries, stages or ages, which curerntly are not formalised.

    Union for Quaternary Research (INQUA) recommends that the Quaternary remain formally defined as a Period within the Geologic Time Scale, the base of which should be placed at Ma. Unique in Earth History, the Quaternary is an interval of frequent measurable and dramatic changes in climate, environment, and human physical and cultural Size: KB. A reconstruction of the paleoceanography based on the results of the above analyses indicates that during the last glacial maximum (18, yrs BP): 1) sea surface temperatures were slightly lower than today; 2) the areal extent of warm Pacific Equatorial water and Tropical Surface water was diminished; 3) the California Current, North Cited by: 3.

    High‐resolution textural, carbonate, microfossil, and oxygen (δ 18 O) and carbon (δ 13 C) stable isotopic analyses are presented for the late Quaternary (isotopic stages 1 to 6) interval of a core at Deep Sea Drilling Project site , situated just south of the present Subtropical Convergence in northernmost Subantarctic surface waters on the southern flank of Chatham Rise in the Cited by: Paleoceanography, scientific study of Earth’s oceanographic history involving the analysis of the ocean’s sedimentary record, the history of tectonic plate motions, glacial changes, and established relationships between present sedimentation patterns and environmental factors.. Prior to the breakup of Pangea, one enormous ocean, Panthalassa, existed on Earth.
