Site 502: Colombia Basin, Western Caribbean [PDF]

open access: yes, 1982
Our specific objective at Site 502 was to recover an undisturbed, complete section that could be used as a Neogene and Quaternary reference section. A complete record such as this would allow intercorrelations between (1) paleomagnetic stratigraphy, (2 ...

Organic Carbon Burial following the Middle Eocene Climatic Optimum (MECO) in the central - western Tethys

open access: yes, 2010
We present trace metal geochemistry and stable isotope records for the middle Eocene Alano di Piave section, NE Italy, deposited during magnetochron C18n in the marginal Tethys Ocean. We identify a $\sim$ 500 kyr long carbon isotope perturbation event we

Reconstruction of a latest Paleocene shallow-marine eutrophic paleoenvironment at Sidi Nasseur (Central Tunisia) based on foraminifera, ostracoda, calcareous nannofossils and stable isotopes (delta13C delta18O) [PDF]

open access: yes, 2009
In order to unravel faunal and paleoenvironmental parameters in shallow marine settings prior to the Paleocene-Eocene thermal maximum, we investigated the Sidi Nasseur section (NAS) in Central Tunisia.
