    Pronghorn (Antilocapra americana) enamel phosphate δ18O values reflect climate seasonality: Implications for paleoclimate reconstruction by Danielle Fraser, Sora L. Kim, Jeffrey M. Welker, Mark T. Clementz

    Published 2021-12-01
    “…Abstract Stable oxygen isotope (δ18O) compositions from vertebrate tooth enamel are widely used as biogeochemical proxies for paleoclimate. However, the utility of enamel oxygen isotope values for environmental reconstruction varies among species. …”

    Middle-Late Quaternary paleoclimate of northern margins of the Saharan-Arabian Desert: reconstruction from speleothems of Negev Desert, Israel by Vaks, A, Bar-Matthews, M, Matthews, A, Ayalon, A, Frumkin, A

    Published 2010
    “…Speleothems in arid and hyper-arid areas of Negev Desert, Israel, are used in paleoclimate reconstruction of northern margins of Saharan-Arabian Desert, focused on the following objectives: 1) precise U-Th dating of the timing of speleothem growth as an indicator of periods of humid climate, i.e. positive effective precipitation; 2) the origin of rainfall using the speleothem δ18O and changes in spatial pattern of speleothem deposition and speleothem thickness along a north-south transect; 3) changes of vegetation cover based on speleothem δ13C variations.During the last 350ka major humid periods, referred to herein as Negev Humid Periods (NHP), occurred in the central and southern Negev Desert at 350-310ka (NHP-4), 310-290ka (NHP-3), 220-190ka (NHP-2), and 142-109ka (NHP-1). …”

    Ocean carbon cycling during the past 130,000 years - a pilot study on inverse paleoclimate record modelling by Heinze, C, Hoogakker, B, Winguth, A

    Published 2016
    “…The overall fit of modelled paleoclimate tracers to observations, however, remains quite weak, indicating the potential of more detailed modelling studies to fully exploit the information stored in the paleo-climatic archive. …”

    Reconstruction of Paleoenvironment and Paleoclimate of the Neogene Guantao Formation in the Liaodong Sub-Uplift of Bohai Bay Basin in China by Sedimentary Geochemistry Methods by Maolin Wang, Yuanhua Qing, Zheyuan Liao, Yuefeng Li, Sheng Li, Zhengxiang Lv, Shijun Ni, Jin Fang, Song Tang, Yawen Yang

    Published 2022-12-01
    “…Based on the evaluation of whether the elements and isotopes can effectively record paleosedimentary environment and paleoclimate information or not, the paleoclimate (temperature and humidity), paleoenvironment (salinity, water depth, redox conditions), and evolution of the paleoenvironment and paleoclimate are studied by analyzing the trace elements, carbon and oxygen isotopes, strontium isotopes, whole-rock mineral compositions, and clay minerals of mudstones of the Guantao Formation in the Liaodong sub-uplift, Bohai Bay Basin. …”
