ICEland-1: a geochronological database for reconstructing Late Quaternary glacier, relative sea level, and paleoclimate patterns in Iceland [PDF]

open access: yesEarth System Science Data
We present a detailed and quality-controlled chronological database for past glacier, relative sea level, and paleoclimate changes in Iceland during the Late Quaternary (∼60 ka): ICEland-1. The curated database includes 1744 data points and metadata from

Cryptotephras in European Arctic: extending tephrochronology to northern Finland and Russia

open access: yes, 2020
Tephrochronology is a powerful method for correlating geological and archeological sequences by utilizing geochemically fingerprinted tephra layers (volcanic ash).

Icelandic tephrochronology - matching the provenance of proximal and distal volcanic glasses using La-ICPMS trace element data

open access: green, 2010
Thorarinsson (1944) pioneered the use of tephrochronology and its application in NW Europe. The basis of this chronological tool is the use of time-parallel marker tephra (i.e., ash

High-resolution Holocene record based on detailed tephrochronology from Torfdalsvatn, north Iceland, reveals natural and anthropogenic impacts on terrestrial and aquatic environments [PDF]

open access: yesClimate of the Past
Open questions remain around the Holocene variability of climate in Iceland, including the relative impacts of natural and anthropogenic factors on Late Holocene vegetation change and soil erosion.

Historical and paleo-tsunami deposits on Kamchatka, Russia: long-term chronologies and long-distance correlations [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2001
Along the eastern coast of Kamchatka, at a number of localities, we have identified and attempted to assign ages to deposits of both historic and prehistoric (paleo-) tsunamis.

Tephra studies in New Zealand: an historical review.

open access: yes, 1990
The development of tephra studies in New Zealand may be divided into four main periods: Period 1, late 19th century to late 1920s; Period 2, late 1920s to early 1950s; Period 3, early 1950s to 1973; Period 4, 1973 to late 1980s.

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
