Dunbar, N., Zielinski, G. and Voisins, D., 2002, Tephra layers in the Siple and Taylor Dome Ice Cores, Antarctica: Correlations and Sources: submitted to Quaternary Research.
This data set is the result of a study of volcanic ash and rock fragment (tephra) layers in exposed blue ice areas on Brimstone Peak (75.888S 158.55E) in East Antarctica. Tephra samples were collected between 15 November 1996 and 15 January 1997.
The Antarctic ice sheets preserve a record of the volcanic ash layers and chemical aerosol signatures of local and distant volcanic eruptions. Correlation of individual tephra layers, or sets of layers, in blue ice areas will allow a better understanding of the geometry of ice flow in these areas. Tephra layers in deep ice cores can also provide unique time-stratigraphic markers in cores that are difficult to date.
Data include the following information for each sample site: a general description, electron microprobe analysis, GPS location, neutron activation analysis, and a visual description of the petrography.Data are provided as Excel 97 data files, JPG map files, and GIF-formatted BSE images.VIEW RELATED INFORMATIONhttps://doi.org/10.7265/N5MG7MDKDocumentationGET DATAhttp://www.usap-dc.org/view/dataset/609114Get External DataCEOS IDN DIFVERSION 9.92003-02-182023-05-23NSIDCVersion SummaryNSIDCMinor VersionNSIDCCurrent Version1NSIDCFull Dataset CitationDunbar, N. 2003. <i>Blue Ice Tephra II - Brimstone Peak.</i> [indicate subset used].
