Contrasting conditions preceding MIS3 and MIS2 Heinrich events

Global and Planetary Change, 2006
This paper presents an integrated multi-tracer study performed on piston cores recovered in the glacial ice-rafted detritus belt, stretching from Newfoundland to the Irish margin across the North Atlantic (40–55°N), in order to compare in detail the internal structure of each Heinrich event (HE). These tracers are IRD counts (quartz, dolomite, volcanic

Dansgaard-Oeschger events in climate models: A PMIP baseline MIS3 protocol

2022
<p>Frequent well documented Dansgaard-Oeschger (D-O) events occurred throughout the MIS3 period. This study lays the ground-work for a MIS3 D-O protocol for CMIP-class models. We consider the over-arching question: Are our models too stable?

Millennial variability, hydrological and limnological changes during MIS3-2 in Lake Petén Itzá, Guatemala

2021
Heinrich Stadials and Greenland Interstadials are abrupt climate variations that are observed in the Northern Hemisphere throughout Marine Isotopic Stages (MIS) 3-2. Lake Petén Itzá, northern Guatemala, is a key site for paleoclimate investigations due to its sensitivity to changes in climate forcing such as the Intertropical Convergence Zone (ITCZ ...

Mid‐MIS3 climate inferred from reconstructing the Dalijia Shan ice cap, north‐eastern Tibetan Plateau

Journal of Quaternary Science, 2015
ABSTRACTThe local last glacial maximum (LGML) on Dalijia Shan occurred during mid‐marine isotope stage 3 (MIS3), which is consistent with some Tibetan Plateau records, but asynchronous with the MIS2 global Last Glacial Maximum (LGMG). Paleoclimatic reconstructions are key to advancing understanding such spatial and temporal patterns of paleoglaciation.

Environmental and climatic context of Neanderthal occupation in southwestern Europe during MIS3 inferred from the small-vertebrate assemblages

Quaternary International, 2014
Abstract According to pollen analysis, Marine Isotope Stage 3 (MIS3, ca. 60–30 ka) is characterized in southern Europe by dynamic alternations of forest vs. semi-arid area expansion in accordance with the warming and cooling, respectively, of the sea-surface temperatures.

Avian remains from the Upper Pleistocene (MIS3) site of Aguilón P-7, south of the Ebro River, Spain

Historical Biology, 2015
Aves are represented by abundant fossil remains in Quaternary sites. Birds are well adapted to the environment they inhabit, so they make very good paleoenvironmental indicators for Quaternary sites. Here we analyse the avian remains from the Late Pleistocene (probably MIS3) site of Aguilon P-7 (AGP-7). The Pleistocene sediments fill up a shallow cave,

The Upper Val Seriana (north-western Italy, Bergamo) during MIS3: small mammals as proxy data

Bollettino della Società Paleontologica Italiana
The Büs di Tri Fradèi cave is located in the municipality of Oltre il Colle (Bergamo province) in north-western Italy. In the cave five main stratigraphic levels occur, of which only one is fossiliferous, corresponding to the Marine Isotope Stage 3 (MIS3). The cave is believed to have served as a nursery for cave bears (Ursus spelaeus), as many remains
