A Paleosol-Derived Environmental Perspective on MIS 3 in the Central Great Plains
The Marine Isotope Stage (MIS) 3 Gilman Canyon Formation (GCF) is a unique stratigraphic unit prevalent throughout the Central Great Plains of North America and serves as an important underutilized archive of paleoenvironmental data. This study focuses on the GCF in central Kansas where it contains …

Laurentide ice sheet meltwater influences and millennial-scale climate oscillations on the northwestern slope of the Gulf of Mexico during Marine Isotope Stage 6 and Termination II
… the Gulf of Mexico during Marine Isotope Stage (MIS) 3 and Termination I, however very little is known about equivalent events during older time intervals. Basin 4 is located on the northwest slope of the Gulf of Mexico and has provided a detailed record of late MIS 6 and Termination II. The …

A multiproxy paleoenvironmental reconstruction of Late Quaternary marine sediments: Sunda Shelf, Southern South China Sea
… and possibly older) during marine isotope stage (MIS) 3 (ca. 60,000 - 30,000 yrs BP) within the late Pleistocene. Elemental and BMS data agree well within both cores, except Pleistocene sediments exhibit higher BMS (ca. 1x10-4 si) and higher calcium content (ca. 2%) than Holocene sediments. These …

A 210,000-year reconstruction of subtropical climates from Fern Gully Lagoon, North Stradbroke Island (Minjerribah), Australia
… data from 40 Australian marine isotope stage 3 (MIS 3; 57 – 29 ka) records, allowing a continental record of moisture availability to be created, and moisture availability during peak Australian megafauna extinction to be identified (Chapter 2). • A chronology for a new wetland sediment record …

Late Quaternary landscape evolution and environmental change in Charwell Basin, South Island, New Zealand
… terrain analysis, loess stratigraphy, soil chemistry and paleoecological data. The study contributes new understanding of New Zealand landscape and ecosystem responses to regional and global climatic change extending to Marine Isotope Stage (MIS) 6, and shows that climatically-forced shifts in …

NEW INSIGHTS INTO THE PALEOVEGETATION OF THE ANCIENT UNDERWATER FOREST LOCATED IN THE NORTHERN GULF OF MEXICO
… of Mexico. This forest existed around 41-72 yBP (MIS 3-5) according to the existing dating methods applied on previous studies. As the climate conditions and sea levels changed, the vegetation of this glacial refuge shifted from bald cypress forests to open marshes, altering the vegetation …

Analysis of Fossil Pollen from a Pleistocene Cypress Forest Preserved on the Northern Gulf of Mexico Continental Shelf
… a BP placing the core in Marine Isotopic Stage (MIS) 3. An extrapolated optically-stimulated luminescence (OSL) date from a sister core to 15DF3B, revealed an age of 72,000 years (early MIS 4 or 5). However, the pollen results from both cores indicate that the peat sections have recorded the same …

Distribuição de mercúrio no Atlântico Sudoeste ao longo dos últimos 40 mil anos
… mais elevados registrados nos períodos glaciais (MIS 2, MIS 3 - Marine Isotope Stages) e os mais baixos no interglacial (MIS 1). O que reflete as condições glaciais, caracterizada por maior aporte de poeira atmosférica, menor nível do mar, maior exposição da plataforma continental e aumento da …

An investigation of the tufa deposits at Ga-Mohana Hill in the Northern Cape, South Africa: palaeoenvironmental context for Late pleistocene and holocene human occupation in the Southern Kalahari
… to indicate water availability during MIS 5d (~114 - 100 ka), MIS 4 (~73-57 ka), two stages during MIS 3 (~57-48 ka, and ~44-32 ka), and two stages during the Holocene (~15 - 6 ka, and ~4-2 ka). This timing supports the notion that conditions for tufa formation are not restricted to …

The use of 10Be surface exposure dating of erratic boulders in the reconstruction of the late Pleistocene glaciation history of mountainous regions, with examples from Nepal and Central Asia
… than the westerly circulation. Only in the MIS 2, the westerly jetstream appears to have shifted as far south as to affect glaciation all over the Himalaya. During the Younger Dryas, the eastern limit of the influence of the westerly circulation on Himalaya glaciation may have been situated …
