Controls on the global distribution of contourite drifts: Insights from an eddy-resolving ocean model
Tharn, Amanda C; Dutkiewicz, Adriana; Spence, Paul Spence; Müller, Dietmar R.Published 2018-05-01Contourite drifts are anomalously high sediment accumulations that form due to reworking by bottom currents. Due to the lack of a comprehensive contourite database, the link between vigorous bottom water activity and drift ...Open AccessArticle -
The GPlates Portal: Cloud-Based Interactive 3D Visualization of Global Geophysical and Geological Data in a Web Browser
Muller, R. Dietmar; Qin, Xiaodong; Sandwell, David T; Dutkiewicz, Adriana; Williams, Simon E; Flament, Nicolas; Maus, Stefan; Seton, MariaPublished 2016-03-03The pace of scientific discovery is being transformed by the availability of 'big data' and open access, open source software tools. These innovations open up new avenues for how scientists communicate and share data and ...Open AccessArticle -
In search of early life: Carbonate veins in Archean metamorphic rocks as potential hosts of biomarkers
Peters, Carl A.; Piazolo, Sandra; Webb, Gregory E.; Dutkiewicz, Adriana; George, Simon C.Published 2016-11-01The detection of early life signatures using hydrocarbon biomarkers in Precambrian rocks struggles with contamination issues, unspecific biomarkers and the lack of suitable sedimentary rocks due to extensive thermal ...Open AccessArticle -
Oceanic crustal carbon cycle drives 26-million-year atmospheric carbon dioxide periodicities
Muller, R. Dietmar; Dutkiewicz, AdrianaPublished 2018-02-02Atmospheric carbon dioxide (CO2) data for the last 420 million years (My) show long-term fluctuations related to supercontinent cycles as well as shorter cycles at 26 to 32 My whose origin is unknown. Periodicities of 26 ...Open AccessArticle -
Sequestration and subduction of deep-sea carbonate in the global ocean since the Early Cretaceous
Dutkiewicz, Adriana; Cannon, John S.; Müller, Dietmar R.; Vaughan, Sioned; Zahirovic, SabinPublished 2019-01-01Deep-sea carbonate represents Earth's largest carbon sink and one of the least-known components of the long-term carbon cycle that is intimately linked to climate. By coupling the deep-sea carbonate sedimentation history ...Open AccessArticle
