Sites 759 through 764 were drilled during Ocean Drilling Program Leg 122 on the Exmouth and Wombat plateaus off northwest Australia, eastern Indian Ocean. Radiolarian recovery...

Low-diversity calcareous dinoflagellate cysts were studied by SEM in 10 samples from the Lower Cretaceous of Hole 761C (256-235 mbsf). The ?late Aptian/Albian age interval can...

The middle Miocene is an important analogue for potential future warm climates. Unfortunately, relatively few independent deep ocean temperature records exist, though these are...

The data are measurements of leaf wax n-alkane compound abundance and associated metrics of compound distribution, leaf wax n-alkane compound specific carbon isotope...

The iterative evolutionary radiation of planktic foraminifers is a well-documented macroevolutionary process. Here we document the accompanying size changes in entire planktic...

The disappearance at ~10 Ma of the deep dwelling planktonic foraminifer Globoquadrina dehiscens from the western Pacific including the South China Sea was about 3 Myr earlier...

The evolution of planktonic foraminifera during the Late Cretaceous is marked in the Santonian by the disappearance of complex morphotypes (the marginotruncanids), and the...

A taxonomic and biostratigraphic investigation has been carried out on Upper Triassic (Carnian-Rhaetian) nannofossils from Sites 759, 760, 761 and 764 drilled on the Wombat...

The morphological variability (coiling properties, size and shape) of the planktic foraminifer Contusortuncana contusa (Cushman) in the terminal Cretaceous ocean was examined at...

A 100-m-thick Paleocene sequence of mainly pelagic sediments at ODP Site 1121, on the eastern flanks of the Campbell Plateau, contains few to common radiolarians of relatively...

Global shallow sediment diagenesis survey results based on all available IODP sediment core images.
