5. Characteristics of tephra in Holocene lake sediments on King George Island, West Antarctica [KPDC-MD-2006-011]
Several reworked tephra layers in gravity-flow deposits are present in lacustrine core sediments collected from Hotel and Rudy lakes on King George Island, South Shetland Islands, W. Antarctica. The ...


6. Collaborative Research: Microparticle/tephra analysis of the WAIS Divide ice core [dunbar_0636767]
Visible tephra layers were found in the Byrd Station ice core, the first deep core drilled in Antarctica. Since then, tephra have been found in many other Antarctic ice cores. Tephra layers in ice ...


7. Collaborative Research: Refining a 500-kyr Climate Record From the Mt. Moulton Blue Ice Field in West Antarctica [dunbar_NSF0230348]
There is intense scientific interest in the history, dynamics and future of the West Antarctic Ice Sheet because it is the world's only remaining marine ice sheet and is considered by ...


8. Crystalline rocks of the Antarctic Peninsula [dlb_APgeothermochron]
This dataset consists of: (1) a suite of crystalline rocks (primarily granitoids & quartzites, with subordinate gneisses, schists, volcanic rocks, and mafic intrusive rocks) collected from the Antarctic ...


9. Erebus hydrogen emissions, oxidation state, phase equilibria, and anorthoclase megacrystals [Y.Moussallam_Erebus_emissions_equilibria_convection_1]   PARENT METADATA
The continuous measurement of molecular hydrogen (H2) emissions from passively degassing volcanoes has recently been made possible using a new generation of low-cost electrochemical sensors. We have ...


10. Erebus source to surface degassing, thermodynamics, solubilities, and magma storage and evolution (2013-2016) [K.Iacovino_papers_ErebusRI_degassing_solubility_evolution_1]   PARENT METADATA
We present new equilibrium mixed-volatile (H2O–CO2) solubility data for a phonotephrite from Erebus volcano, Antarctica. H2O–CO2-saturated experiments were conducted at 400–700 MPa, ...


11. Eruptive history and magmatic stability of Erebus volcano, Antarctica: Insights from englacial tephra [N.Iverson_eruptive_magmatic_englacial_tephra_Erebus_1]   PARENT METADATA
A tephrostratigraphy of the active Antarctic Erebus volcano was determined from englacial tephra on the ice-covered flanks of Erebus and an adjacent volcano. The tephra are used to reconstruct the ...


12. Geochemical analyses and images of tephra and other particulate samples from the Law Dome Ice Core [Law_Dome_Tephra]
This data set contains geochemical information and backscattered electron images of particulate material sampled from the Law Dome ice core. Some of this material is volcanic ash, and ...


13. Geology of Seymour Island, Antarctica [CDA_AR_GEO_SEYMOUR_SEDIMENTOL]
Currently, the data set is comprised of approximately 450 granulometric analyses of 70 loose grain mineralogical preparations from 30 geological sections of Seymour Island, Antarctica. The data set ...


14. Micrometeorites from the South Pole Water Well [NSIDC-0113]
Micrometeorites dated between 1100 A.D. to 1500 A.D. were collected from the bottom of the South Pole Water Well in December 1995. Element analyses of 181 cosmic glass spherule and micrometeorite ...


15. Rheology of phonolitic magmas - the case of the Erebus lava lake [C.LeLosq_phonolite_magma_rheology_1]   PARENT METADATA
Long-lived active lava lakes are comparatively rare and are typically associated with low-viscosity basaltic magmas. Erebus volcano, Antarctica, is unique today in hosting a phonolitic lava lake. ...
