Northern Hemisphere Glaciation during the Globally Warm Early Late Pliocene [PDF]
, 2013 The early Late Pliocene (3.6 to ~3.0 million years ago) is the last extended interval in Earth's history when atmospheric CO2 concentrations were comparable to today's and global climate was warmer.

Trophic Changes off Southwest Greenland During the Holocene and Their Influence on Carbon Burial
Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract Organic carbon (OC) burial in sediments is partly controlled by catabolic biodegradation and remineralization by heterotrophic bacteria, but long‐term records of these bacterially‐mediated processes have not been available. Here, we use stable hydrogen isotope ratio of the saturated C16 fatty acid (δ2HC16:0) as a proxy of the prevalence of ...

Biostratigraphy, facies and sequence stratigraphy of the Sarvak Formation in the Ahwaz Oil Field, North Dezful Embayment Zone [PDF]
Journal of Stratigraphy and Sedimentology Researches, 2016 Paleontological studies lead to recognition of 21 genera and 16 species of benthic foraminifera, 5 genera and 6 species of planktonic foraminifera and 3 genera and 3 species of oligosteginids.

New insight into the Pleistocene deposits of Monte delle Piche, Rome, and remarks on the biochronology of Hippopotamus (Mammalia, Hippopotamidae) and Stephanorhinus etruscus (Mammalia, Rhinocerotidae) in Italy [PDF]
, 2015 Several large mammal assemblages have been collected in the Roman basin since the XIX century, but they usually lack any stratigraphic datum or details about the fossiliferous localities. In this work, the stratigraphic provenance of large mammal remains

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract In contrast to previous approaches, new reconstructions of changes in global mean surface temperature and global mean sea level (GMSL) include large variability in GMSL throughout the Pleistocene. Here we assess these reconstructions from an energy balance perspective by using them to force a global carbon cycle model in different scenarios ...

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.Abstract Evaluating the state of activity of Deep‐Seated Gravitational Slope Deformation (DSGSD) is a challenge that requires multidisciplinary analytical approaches. This research focuses on the slope‐scale gravitational process, framing the role of the Quaternary morphodynamics of a river valley where multiple DSGSDs coexist, to reconstruct the ...

Late Holocene hydrographic settings of the northern Red Sea
Egyptian Journal of Aquatic Research, 2016 Temporal variability of the paleo-oceanographic setting of the northern Red Sea during the last 6 Ky was deduced from high-resolution faunal results and stable isotope records of planktonic foraminifera in three short cores sediment obtained by the ...

New Zealand Geological Timescale 2025
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.New Zealand Geological Timescale 2025 (NZGT 2025) is the first comprehensive update and revision of the New Zealand Geological Timescale in a decade. The criteria used to establish age ranges of New Zealand Stages within the NZGT have been reviewed, calibrated, and revised where required against the 2023/04 International Chronostratigraphic Chart and ...

Oxygen isotopic paleotemperatures across the Runangan-Whaingaroan (Eocene-Oligocene) boundary in a New Zealand shelf sequence [PDF]
, 1981 Oxygen isotopic compositions of the tests of mainly benthic foraminifera, from sections of conformable Late Eocene (Runangan) to Early Oligocene (Whaingaroan) shelf mudstones, at both Cape Foulwind and Port Elizabeth, western South Island, indicate that ...

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.Abstract This study presents a high‐resolution reconstruction of the Antarctic Intermediate Water (AAIW) transport variability on the southeastern Brazilian continental margin over the last 16,000 years BP, based on grain‐size analysis. Variations of sortable silt (SS¯$$ \overline{SS} $$) are interpreted as changes in flow speed of the Intermediate ...
