A conceptual model of multi-scale formation processes of open-air Middle Paleolithic sites in the arid Negev desert, Israel Quat. Res. (IF 2.3) Pub Date : 2023-07-12 Maya Oron, Joel Roskin, Yoav Avni, Naomi Porat, Emil Aladjem, Dmitry Yegorov, Jacob Vardi, Erella Hovers
Open-air surface accumulations and scatters of material cultural remains often are perceived as less-reliable archaeological archives, where it is difficult to distinguish anthropogenic versus geogenic formation processes or to assess their specific effects on the integrity of archaeological records. Here we analyze the depositional histories of three Middle Paleolithic open-air sites in the Negev

A ca. 39,000-year record of vegetation and climate change from the margin of the Namib Sand Sea Quat. Res. (IF 2.3) Pub Date : 2023-07-11 Brian M. Chase, Arnoud Boom, Andrew S. Carr, Michael E. Meadows, Sophak Lim
This paper presents the first continuous multi-proxy record of climate and vegetation change from the central Namib Desert extending over much of the last ca. 39,000 years. Derived from rock hyrax middens, evidence from stable carbon and nitrogen isotopes, pollen, and microcharcoal reveals significant differences between glacial-age and Holocene climates and vegetation types. Although still arid to

Climate variability in the northern Levant from the highly resolved Qadisha record (Lebanon) during the Holocene optimum Quat. Res. (IF 2.3) Pub Date : 2023-07-03 Carole Nehme, Sophie Verheyden, Tobias Kluge, Fadi H. Nader, R. Lawrence Edwards, Hai Cheng, Elisabeth Eiche, Philippe Claeys
New stalagmites from Qadisha Cave (Lebanon) located at 1720 m above sea level provide a high-resolution and well-dated record for northern Mount Lebanon. The stalagmites grew discontinuously from 9.2 to 5.7 and at 3.5 ka, and they show a tendency to move from a more negative oxygen isotope signal at ~9.1 ka to a more positive signal at ~5.8 ka. Such a trend reflects a change from a wetter to a drier

A Holocene pollen-inferred climate reconstruction for Vermont, USA Quat. Res. (IF 2.3) Pub Date : 2023-07-03 Laurie D. Grigg, Ioana C. Stefanescu, Bryan N. Shuman, W. Wyatt Oswald
A 13.0 cal ka BP pollen record from Twin Ponds, Vermont, provides new insights into the climate history of the northeastern United States. Modern analogs were used to produce qualitative and quantitative climate reconstructions for Twin Ponds. The Twin Ponds record was compared with nearby Knob Hill Pond to develop a Vermont reconstruction that was compared with reconstructions from two sites at a

A Late Holocene climate reconstruction from the high-altitude Lake Gölcük sedimentary records, Isparta (SW Anatolia) Quat. Res. (IF 2.3) Pub Date : 2023-06-26 Iliya Bauchi Danladi, Sena Akçer-Ön, Thomas Litt, Z. Bora Ön, Lukas Wacker
A high-resolution multiproxy lake sediment dataset, comprising lithology, radiography, μXRF elemental, magnetic susceptibility (MS), δ13C, and δ18O measurements since ca. AD 400 is presented in this study. Changes in lithology, radiography, magnetic susceptibility (MS), δ13C, and δ18O reflect wet/dry climate periods, whereas variability in log(Ca/K) can reflect warm/cold climate periods. Analyses of

Massive ground ice of glacial meltwater origin in raised marine-deltaic sediments, Fosheim Peninsula, high Arctic Canada Quat. Res. (IF 2.3) Pub Date : 2023-06-22 Cameron Roy, Kethra Campbell-Heaton, Denis Lacelle, Wayne Pollard
In the Canadian high Arctic, tabular massive ground ice is found extensively throughout the Eureka Sound Lowlands (ESL). This study evaluates the development of tabular massive ice in raised marine-deltaic sediments of the ESL based on new cryostratigraphic data from sites found between the coastline and the Holocene marine limit. At all sites, massive ice is found below laminated fine-grained marine

Implications of submonthly oxygen and carbon isotope variations in late Pleistocene Melanopsis shells for regional and local hydroclimate in the upper Jordan River valley Quat. Res. (IF 2.3) Pub Date : 2023-06-20 Addison Rice, Elizabeth Bunin, Birgit Plessen, Gonen Sharon, Steffen Mischke
Many water-stressed regions of the globe have a highly seasonal precipitation regime. However, seasonality in the past and under changing climates is little studied. Submonthly records of sclerochronological δ18O and δ13C values of Melanopsis shells from the Jordan River Dureijat archaeological site (JRD) in the upper Jordan River valley presented here document the hydrology of paleo-Lake Hula. These

Onset of dune construction based on archaeological evidence, White Sands, New Mexico Quat. Res. (IF 2.3) Pub Date : 2023-06-19 Vance T. Holliday, Matthew Cuba, Wayne Lee, Jason Windingstad, Brendan Fenerty, David Bustos
The White Sands dune field is the largest gypsum dune system in the world, derived from deflation of paleo-Lake Otero deposits. Understanding the timing of initial dune construction, and therefore lake deflation, is critical for understanding regional landscape evolution, including the history of lake desiccation. The onset of dune construction is currently estimated at ~8000 to 6500 cal yr BP, but

Climate change intensified violence in the south-central Andean highlands from 1.5 to 0.5 ka Quat. Res. (IF 2.3) Pub Date : 2023-06-05 Thomas J. Snyder, Randall Haas
The archaeology of the pre-contact Andes provides an ideal study of human responses to climate change given the region's extreme climatic variability, excellent archaeological preservation, and robust paleoclimate records. We evaluate the effects of climate change on the frequency of interpersonal violence in the south-central Andes from ca. 1.5–0.5 ka (AD 470–1540) by comparing incidents of skeletal

Pliocene–Pleistocene hydrology and pluvial lake during Marine Isotope Stages 5a and 4, Deep Springs Valley, western Great Basin, Inyo County, California Quat. Res. (IF 2.3) Pub Date : 2023-06-01 Jeffrey R. Knott, Shannon A. Mahan, Jordon Bright, Lindsey Langer, Adam Ramirez, Kyle McCarty, Anna L. Garcia
Deep Springs Valley (DSV) is a hydrologically isolated valley between the White and Inyo mountains that is commonly excluded from regional paleohydrology and paleoclimatology. Previous studies showed that uplift of Deep Springs ridge (informal name) by the Deep Springs fault defeated streams crossing DSV and hydrologically isolated the valley sometime after eruption of the Pleistocene Bishop Tuff (0

The role of lithology and climate on bedrock river incision and terrace development along the Buffalo National River, Arkansas Quat. Res. (IF 2.3) Pub Date : 2023-05-26 Kathleen Rodrigues, Amanda Keen-Zebert, Stephanie Shepherd, Mark R. Hudson, Charles J. Bitting, Bradley G. Johnson, Abigail Langston
The Buffalo National River in northwest Arkansas preserves an extensive Quaternary record of fluvial bedrock incision and aggradation across lithologies of variable resistance. In this work, we apply optically stimulated luminescence (OSL) dating to strath and fill terraces along the Buffalo River to elucidate the role of lithology and climate on the development of the two youngest terrace units (Qtm

Interrelation of radiocarbon ages from bone fractions in the Brazilian Intertropical Region Quat. Res. (IF 2.3) Pub Date : 2023-05-17 Mário André Trindade Dantas, Alexander Cherkinsky
There is a consensus in the literature that radiocarbon dating performed on bioapatite often produces ages younger than dating performed on collagen. We propose a general regression that could be used to convert the bioapatite radiocarbon ages to the simulated ages on collagen in fossil samples worldwide. This general regression presents several good indices of quality, high correlation (R2 = 0.98)
