Chironomid-based temperature reconstruction for the Eemian Interglacial (MIS 5e) at Sokli, northeast Finland [PDF]

, 2019
The Last Interglacial (Eemian, MIS 5e) can be considered a test-bed for climate dynamics under a warmer-than-present climate. In this study we present a chironomid record from the high latitude Sokli site (N Finland), where a long continuous sediment ...

Amplified bioproductivity during Transition IV (332 000–342 000 yr ago): evidence from the geochemical record of Lake El'gygytgyn [PDF]

, 2013
To date, terrestrial archives of long-term climatic change within the Arctic have widely been restricted to ice cores from Greenland and, more recently, sediments from Lake El'gygytgyn in northeast Arctic Russia.

Halophytes Dispersion Patterns and Soil Salinity Concentration Across the Egyptian North-Western Mediterranean Coast [PDF]

International Journal of Environmental Studies and Researches, 2023
Global climate change is considered the largest threat to the natural environment. To understand Earth's fundamental climate changes. We must look back for millions of years, without humans, climate altered between glacial and interglacial periods, and ...

Ice-proximal sea ice reconstruction in the Powell Basin, Antarctica, since the Last Interglacial [PDF]

Climate of the Past
In Antarctica, the presence of sea ice not only plays a critical role in the climate system but also contributes to enhancing the stability of the floating ice shelves.

Low Florida coral calcification rates in the Plio-Pleistocene [PDF]

Biogeosciences, 2016
In geological outcrops and drill cores from reef frameworks, the skeletons of scleractinian corals are usually leached and more or less completely transformed into sparry calcite because the highly porous skeletons formed of metastable aragonite (CaCO3 ...

MIGRATION OF HOMININS WITH MEGAHERBIVORES INTO EUROPE VIA THE DANUBE-PO GATEWAY IN THE LATE MATUYAMA CLIMATE REVOLUTION

Rivista Italiana di Paleontologia e Stratigrafia, 2014
We update critical reviews of sites bearing hominin remains and/or tools from Europe (including the Balkans and Greece) and conclude that the only compelling evidence of hominin presence in these regions was after ~0.9 Ma (million-years-ago), bracketed ...

Potential seaways across West Antarctica [PDF]

, 2011
The West Antarctic ice sheet (WAIS) has long been considered vulnerable to rapid retreat and today parts are rapidly losing ice. Projection of future change in WAIS is, however, hampered by our poor understanding of past changes, especially during ...

Late Quaternary palaeoenvironmental changes documented by microfaunas and shell stable isotopes in the southern Pearl River Delta plain, South China

Journal of Palaeogeography, 2013
A high resolution study of sediments, microfaunas (ostracods and foraminifers), and stable isotopes of ostracod shells from core PRD05, sampled from the Da'ao plain of the Pearl River Delta, provides new data about palaeoenvironmental changes during the ...

Benthic Foraminiferal Oxygen Isotope Offsets Over The Last Glacial-Interglacial Cycle

, 2010
The oxygen isotope (?18O) offset between contemporaneous benthic foraminiferal species is often assumed constant with time and geographic location. We present an inventory of benthic foraminiferal species ?18O offsets from the major ocean basins covering
