Abstract

Studies of the Last Interglacial (ca. 129 to 116 ka BP) provide an opportunity to study the impact of high-latitude warm temperatures on the Earth system. To build an accurate spatio-temporal picture of climate and environmental variability during the Last Interglacial, building robust chronologies, through which the patchwork of terrestrial, marine, and ice core archives can be correlated, is paramount. In this review, we briefly evaluate the most common approaches used to date climate and environmental archives from the Last Interglacial, as well as the chronostratigraphic tools available for direct correlation between sequences, with a focus on terrestrial archives. We then present a case study on the use of pollen biostratigraphy for correlating sequences in NW Europe, highlighting its strength as a local correlation tool, and the challenges this approach presents in comparing sequences to global records of climate and environmental change. A move towards consistently dated sequences will improve our understanding of environmental responses to Last Interglacial climate variability across different elements of the global climate system and the rates at which different elements of the climate system respond to changes in global temperatures.

末次冰期序列的年代学进展
对末次冰期(约公元前 129 至 116 ka 年)的研究为研究高纬度暖温对地球系统的影响提供了机会。要准确描述末次冰期气候和环境变异的时空图景,最重要的是建立健全的年代学,通过这些年代学可以将陆地、海洋和冰芯档案联系起来。在这篇综述中,我们简要评估了用于确定末次冰期气候和环境档案日期的最常用方法,以及用于序列间直接关联的年代地层学工具,重点是陆地档案。然后,我们介绍了利用花粉生物地层学对西北欧序列进行关联的案例研究,强调了花粉生物地层学作为地方关联工具的优势,以及这种方法在将序列与全球气候和环境变化记录进行比较时所面临的挑战。采用年代一致的序列将使我们更好地了解全球气候系统不同要素对末次冰期气候变异的环境反应,以及气候系统不同要素对全球温度变化的反应速度。

期刊介绍: The Journal of Quaternary Science publishes original papers on any field of Quaternary research, and aims to promote a wider appreciation and deeper understanding of the earth''s history during the last 2.58 million years. Papers from a wide range of disciplines appear in JQS including, for example, Archaeology, Botany, Climatology, Geochemistry, Geochronology, Geology, Geomorphology, Geophysics, Glaciology, Limnology, Oceanography, Palaeoceanography, Palaeoclimatology, Palaeoecology, Palaeontology, Soil Science and Zoology. The journal particularly welcomes papers reporting the results of interdisciplinary or multidisciplinary research which are of wide international interest to Quaternary scientists. Short communications and correspondence relating to views and information contained in JQS may also be considered for publication.
