Assessing the statistical uniqueness of the Younger Dryas: a robust multivariate analysis [PDF]

open access: yesClimate of the Past, 2021
During the last glacial period (ca. 120–11 kyr BP), dramatic temperature swings, known as Dansgaard–Oeschger (D–O) events, are clearly manifest in high-resolution oxygen isotope records from the Greenland Ice Sheet.

The state of knowledge on the deglaciation of America in 2017

open access: yesCuadernos de Investigación Geográfica, 2017
This work presents a summary of all contributions included in this Special Issue on the deglaciation of America. It analyses the differences and coincidences between the phases of glacial evolution and their chronology in each of the regions studied, and

Arctic drainage of Laurentide Ice Sheet meltwater throughout the past 14,700 years

open access: yesCommunications Earth & Environment, 2022
A strong outflow event from Lake Agassiz at the end of the Bølling-Allerød plausibly caused the Younger Dryas cold period by an abrupt Arctic freshening, according to geochemical investigation of sediment cores from the Canadian Arctic.

Revisiting the andean tropical glacier behavior during the Antarctic cold reversal

open access: yesCuadernos de Investigación Geográfica, 2017
The sensitivity of tropical glaciers to paleoclimatic conditions that prevailed during the Antarctic cold reversal (ACR, ca. 14.5-12.9 ka) has been the subject of a wide debate.

Organic carbon isotope record since the Late Glacial period from peat in the North Bank of the Yangtze River, China

open access: yesEuropean Journal of Remote Sensing, 2020
Detailed organic carbon isotope (δ13Corg) measurements were conducted on two peat sequences recovered from the north bank of the Yangtze River, East China. Seven radiocarbon dates provided firm age control of this δ13Corg record and reveal palaeoclimatic

Glacial geomorphology in the Wicklow Mountains, Ireland

open access: yesJournal of Maps, 2023
We present a detailed 1:50,000-scale glacial geomorphological map covering ∼450 km2 of the Wicklow Mountains, eastern Ireland. The region was glaciated at the Last Glacial Maximum, but little is known about the timing and pattern of deglaciation during ...

The Distal and Local Volcanic Ash in the Late Pleistocene Sediments of the Termination I Interval at the Reykjanes Ridge, North Atlantic, Based on the Study of the Core AMK-340

open access: yesGeosciences, 2019
We made the geochemical analysis of the volcanic material from the sediment core AMK-340 (the Russian research vessel “Akademik Mstislav Keldysh” station 340), the central zone of the Reykjanes Ridge. Two ash-bearing sediment units within the

Glacial geomorphology of the Republic of Karelia, northwest Russia: the Younger Dryas-early Holocene ice marginal zone

open access: yesJournal of Maps, 2023
At present, there remains uncertainty surrounding the Younger Dryas-early Holocene glacial history of the Fennoscandian Ice Sheet in northwest Arctic Russia.

Global Younger Dryas?

open access: yesEos, Transactions American Geophysical Union, 1993
Researchers examining the Younger Dryas (YD) paleoclimatic oscillation were brought together at an international, interdisciplinary workshop sponsored by PAGES (Past Global Climate Changes) and the Lamont‐ GISS (Goddard Institute for Space Studies) Climate Center and organized by D. Peteet.

The magnetic record of the Late Glacial-Holocene transition in sediments from Grandfather Lake (Southwest Alaska) [PDF]

open access: yesGeofísica Internacional, 1999
Preliminary rock magnetic measurements on a 8.5 m long sediment core from Grandfather Lake, southwest Alaska, indicate that the remanence in these sediments is carried by large multi-domain magnetite grains. This suggests a detrital magnetic signal.
