Mapping Stratigraphic Discontinuities in West Candor Layered Deposits and the Potential for Sequence Stratigraphic

Introduction: Other than the few Martian meteorites that have been found on Earth and the data being collected by the Mars Exploration Rovers, all data from Mars is remotely sensed which lends it to be developed and analyzed within a Geographic Information System (GIS) platform. This study is being accomplished by bringing together multiple datasets from the Mars Orbiter Camera (MOC), Mars Orbi...

In Cedar Creek Bog, Minnesota Stratigraphic Distribution of Lipoid Substances

The lake and bog deposits of Cedar Creek Forest, Isanti and Anoka counties, Minnesota, consist of a multiple-facies accumulation of marl, peat, copropel, and sapropel. Chromatographic analyses of the lipoid extracts of samples of the sediments show measurable amounts of saturated and aromatic hydrocarbons as well as large proportions of asphalts and polar lipoid compounds. In general compositio...

Probabilistic sequence alignment of stratigraphic records

The assessment of age uncertainty in stratigraphically aligned records is a pressing need in paleoceanographic research. The alignment of ocean sediment cores is used to develop mutually consistent age models for climate proxies and is often based on the δO of calcite from benthic foraminifera, which records a global ice volume and deep water temperature signal. To date, δO alignment has been p...
