High-resolution analyses of ice cores from Antarctica and Greenland reveal an explosive volcanic eruption in the tropics in A.D. 1809 which is not reflected in the historical record. A comparison in the same ice cores of the sulfate flux from the A.D. 1809 eruption to that from the Tambora eruption (A.D. 1815) indicates a near-equatorial location and a magnitude roughly half that of Tambora. Thus this event should be considered comparable to other eruptions producing large volumes ofsulfur-rich…

Ice core evidence for a second volcanic eruption around 1809 in the Northern Hemisphere
A volcanic signal observed in ice cores from both polar regions six years prior to Tambora is attributed to an unknown tropical eruption in 1809. Recovery of dacitic tephra from the 1809 horizon in a
A 780-year record of explosive volcanism from DT263 ice core in east Antarctica
Ice cores recovered from polar ice sheet received and preserved sulfuric acid fallout from explosive volcanic eruptions. DT263 ice core was retrieved from an east Antarctic location. The ice core is
Ice core and palaeoclimatic evidence for the timing and nature of the great mid‐13th century volcanic eruption
Ice cores from both the Arctic and Antarctic record a massive volcanic eruption in around AD 1258. The inter‐hemispheric transport of ash and sulphate aerosol suggests a low‐latitude explosive
A 12,000 Year Record of Explosive Volcanism in the Siple Dome Ice Core, West Antarctica
[1] Air mass trajectories in the Southern Hemisphere provide a mechanism for transport to and deposition of volcanic products on the Antarctic ice sheet from local volcanoes and from tropical and
A 2680 year volcanic record from the DT-401 East Antarctic ice core
[1] Volcanic signals recorded in the Antarctic and Greenland ice cores can provide useful information on past explosive volcanism and its impact. In this study, we carried out a continuous sulfate
A detailed 2840 year record of explosive volcanism in a shallow ice core from Dome A, East Antarctica
Abstract A detailed history of volcanism covering the last 2840 years is reconstructed from the top 100.42 m of a 109.91 m ice core from Dome A (DA2005 ice core), East Antarctica. Using two known
The unidentified volcanic eruption of 1809: why it remains a climatic cold case
Abstract. The 1809 eruption is one of the most recent unidentified volcanic eruptions with a global climate impact. Even though the eruption ranks as the 3rd largest since 1500 with an eruption
Two closely-spaced peaks of electrical conductivity were foundat depths between 45 and 50 m of the 120-m long ice core drilled at site H15 in Antarctica by the 32nd Japanese Antarctic Research
The unidentified eruption of 1809: a climatic cold case
Abstract. The “1809 eruption” is one of the most recent unidentified volcanic eruptions with a global climate impact. Even though the eruption ranks as the third largest since 1500 with a sulfur
Volcanic markers for dating the onset of the Anthropocene
Abstract Volcanic ash is dispersed over thousands of kilometres during large-scale eruptions, forming sedimentary layers. These ash (tephra) deposits are increasingly being used as unique marker


Acidity of polar ice cores in relation to absolute dating, past volcanism, and radio-echoes
' A simple method is described for detecting annual stratification of ice cores, and layers of high acidity due to violent volcanic eruptions in the past. The method is based on a relationship
An Inter-Hemispheric Volcanic Time-Marker in Ice Cores from Greenland and Antarctica
A strong volcanic-acid signal is clearly registered, using an acidity-measuring technique, in the A.D. 1259 ice layer in four different Greenland ice cores (Camp Century, Milcent, Crête and Dye 3).
The Laki and Tambora eruptions as revealed in Greenland ice cores from 11 locations
Major volcanic eruptions deposit large amounts of strong acids in polar ice. Two such volcanic eruptions are Laki, A.D. 1783, at high latitude (64 oN), and Tambora, A.D. 1815, close to the Equator (8
Little Ice Age (Neoglacial) Paleoenvironmental Conditions At Siple Station, Antarctica
The 550-year records of δ 18O and dust concentrations from Siple Station, Antarctica suggest warmer and less dusty atmospheric conditions from 1600 to 1830 A.D. which encompasses much of the northern
Climatic impact of explosive volcanic eruptions
Major explosive volcanic eruptions inject ash and gas into the upper atmosphere, producing aerosol layers which can affect the global energy balance and climate1. Empirical studies have shown that
The explosive volcanic eruption signal in northern hemisphere continental temperature records
Several catalogs of explosive volcanic eruptions are reviewed and their limitations assessed. A new, homogeneous set of high quality gridded temperature data for continental regions of the northern
Volcanic deposits in Antarctic snow and ice
Major volcanic eruptions are able to spread large amounts of sulfuric acid all over the world. Acid layers of volcanic origin were detected for the first time a few years ago by Hammer in Greenland
Surface Temperature Changes Following the Six Major Volcanic Episodes between 1780 and 1980
Abstract Examined is the effect on surface temperature of the volcanic eruptions of Asama and Laki in 1783, Tambora in 1815, Coseguina in 1835, Krakatoa in 1883, Santa Maria, Soufriere and Pelee in
