A revised mid-Pliocene composite section centered on the M2 glacial event for ODP Site 846

چکیده

Abstract. The composite section from ODP Site 846 has provided key data sets for Pliocene stable isotope and paleoclimatic time series. We document here apparent outliers in previously published isotopes alkenone-derived sea surface temperature (SST) estimates the interval containing M2 glaciation (ca. 3.290–3.3 Ma) by tying high-resolution core measurements to a continuous downhole conductivity log. generate revised sequence of new isotopic alkenone across event that correlate well splices color reflectance gamma ray attenuation porosity evaluator 846, produced at equatorial Pacific 850. A splice is proposed, along with series should be integrated into stacks.

The Event Processing ODP

In this abstract we present a model for representing heterogeneous event objects in RDF, building on pre-existing work and focusing on structural aspects, which have not been addressed before, such as composite event objects encapsulating other event objects. The model extends the SSN and Event-F ontologies, and is available for download in the ODP portal.

Eocene-Pliocene deep sea ostracodes from ODP site 744A, Southern Indian Ocean.

The Eocene-Pliocene deep sea ostracodes from the ODP site 744A (Kerguelen Plateau) are herein studied under the taxonomic and paleoecologic aspects. 28 species are identified, being the genera Krithe, Cytherella and Dutoitella the most diversified. A faunal threshold was recorded in the Early Oligocene, which is tentatively explained under the knowledge of the paleoceanographical studies carrie...

Specification of composite objects based on the ODP Reference Model

In this paper, we describe our experience in using the RM-ODP to specify composite objects. The concept of a composite object as defined in RM-ODP does not take into account its dynamic structure as well as the classification of its properties into inherent, aggregate and emergent properties. To make this possible, we have to complement the description of composite objects with explicit contrac...
