Abstract

Abstract : Our long-term goals are to use mass physical properties measured in a suite of Arctic Ocean sediments cores combined with the sediments' mineralogical and chemical compositions to obtain insight into present and past sedimentary processes in high latitude deep-sea (200 m depth) depositional environments. Over the longer term we will use mass physical properties of sediment to conduct ground truth studies of seismic stratigraphic records of glacial marine facies from a variety of high latitude, cold climate environments. We will also use the chemical attributes of the sediment cores to assess the health of the environmentally sensitive Arctic region studied with respect to potentially toxic metals/metalloids.
