Assessing the ability of the 14C projection-age method to constrain the circulation of the past in a 3-D ocean model [PDF]

, 2008
Radiocarbon differences between benthic and planktonic foraminifera (B-P ages) and radiocarbon projection ages are both used to determine changes of the past ocean circulation rate.

Paleoenvironmental Stasis for the Bioturbating Community During the Paleocene‐Eocene Thermal Maximum at the Southern Iberian Margin

Geobiology, Volume 24, Issue 3, May/June 2026.
ABSTRACT During the Paleocene‐Eocene Thermal Maximum (PETM), there was an increase in global temperatures and emissions of isotopically depleted carbon, resulting in a negative carbon isotope excursion (CIE). This climatic event caused a widespread ocean deoxygenation, leading to substantial biotic turnover.

The sedimentary legacy of a palaeo-ice stream on the shelf of the southern Bellingshausen Sea: Clues to West Antarctic glacial history during the Late Quaternary [PDF]

, 2010
A major trough ("Belgica Trough") eroded by a palaeo-ice stream crosses the continental shelf of the southern Bellingshausen Sea (West Antarctica) and is associated with a trough mouth fan ("Belgica TMF") on the adjacent continental slope.

Variability of the Deep‐Water Inputs From the Adriatic and Aegean Seas Over the Period of Sapropel S1 Deposition Based on Foraminiferal Nd Isotopes

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Deep‐water of the eastern Mediterranean basins mainly forms in the Adriatic Sea and episodically in the Aegean Sea. However, past and future variability under changing temperature and freshwater inputs remains unclear. We reconstruct seawater εNd from Northern Ionian Sea cores to trace intermediate‐ and deep‐water provenance during the ...

History of oceanic front development in the New Zealand sector of the Southern Ocean during the Cenozoic--a synthesis [PDF]

, 2001
The New Zealand sector of the Southern Ocean (NZSSO) has opened about the Indian-Pacific spreading ridge throughout the Cenozoic. Today the NZSSO is characterised by broad zonal belts of antarctic (cold), subantarctic (cool), and subtropical (warm ...

Shelf-Ocean material exchange influencing the Atlantic chemical composition off NW Iberian margin since the last glaciation [PDF]

, 2010
Rivers are the main conduit of sediment to the shelf. The basin geology, the drainage area and the discharge rate are the major factors that determine their sediment load (Milliman and Syvistski, 1992).

X-raying planktonic foraminifera [PDF]

Journal of Micropalaeontology, 1988
Abstract. X-raying planktonic foraminifera provides a rapid, efficient and cost-effective method of recording many specimens for biometric analysis. A new approach is here proposed which replaces previous complicated techniques.

Reduced sediment accumulation rate enhances early marine diagenesis of periplatform sediments

The Depositional Record, Volume 12, Issue 2, April 2026.
The influence of reduced sediment accumulation rate on early marine burial diagenesis was investigated in sediments collected by ODP Leg 133. Results show that low sediment accumulation rates can produce substantial and asynchronous shifts in stable carbon isotope ratios across a slope transect without the development of sedimentological indicators of ...

Biostratigraphy, facies and sequence stratigraphy of the Sarvak Formation in the Ahwaz Oil Field, North Dezful Embayment Zone [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2016
Paleontological studies lead to recognition of 21 genera and 16 species of benthic foraminifera, 5 genera and 6 species of planktonic foraminifera and 3 genera and 3 species of oligosteginids.
