Glacial‐Interglacial Shifts in Export Productivity and Iron Flux in the Indian Sector of the Southern Ocean

Paleoceanography and Paleoclimatology, Volume 41, Issue 8, August 2026.
Abstract Greater ocean export productivity fueled by enhanced delivery of iron to the Sub‐Antarctic Zone (SAZ) of the Southern Ocean is hypothesized to play an important role in reducing atmospheric CO2 during Pleistocene glaciations. However, spatial variability in iron input and nutrient availability complicates quantifying the integrated impact of ...

Neogene Changes in Caribbean Paleoproductivity and the Diversity and Paleobiogeography of Deep-sea Benthic Foraminifera [PDF]

, 2016
The Neogene history of Caribbean deep-sea benthic foraminifera was investigated by calculating changes in paleoproductivity, diversity and paleobiogeography ~26 to 2 Ma, which includes the progressive closure of the Central American Seaway.

Tracking via Coccolith Assemblages the East Asian Monsoon and Carbonate Production in the South China Sea During Termination II and Marine Isotope Stage 5e

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract Coccolith assemblages from the last 158 kyr, encompassing Marine Isotope Stage (MIS) 5e (130–116 kyr) and preceding deglaciation (Termination II; T‐II), offer important insights about current and future climate changes. The South China Sea (SCS) represents a perfect area for reconstructing past East Asian Monsoon (EAM) dynamics thanks to its ...

Late Miocene carbon isotope and paleoproductivity record

, 2006
We examine whether or not a relationship exists between the late Miocene carbon isotope shift (~7.6-6.6 Ma) and marine productivity at four sites from the Indian and Pacific Oceans (Ocean Drilling Program Sites 721, 1146, 1172, and 846).

CHANGES OF THERMOCLINE DEPTH AT THE SUMBA ISLAND OFFSHORE BASED ON PLANKTONIC FORAMINIFERAL ASSEMBLAGES AND ITS IMPLICATION TO EUTROPHICATION SINCE THE LAST DEGLACIATION (~18 ka BP): A PRELIMINARY STUDY

Rudarsko-geološko-naftni Zbornik, 2021
Changes of the thermocline depth (DOT) at the Sumba Island offshore are not well-known compared to the DOT changes in the Timor Sea, the main exit passage of the Indonesian Through-flow (ITF).

Seismic Stratigraphy of the Peruvian Forearc Drifts from 3° to 7°S: Identification and Influence of Lower Layers of the Humboldt Current System

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract The seafloor morphology and subsurface geometry of a late Neogene contourite drift located along the Peru margin is documented for the first time using multibeam bathymetry, two‐dimensional and three‐dimensional seismic data. Along the margin several submarine canyons incise the shelf and slope.

Paleoproductivity in the SW Pacific Ocean During the Early Holocene Climatic Optimum [PDF]

Paleoceanography and Paleoclimatology, 2019
AbstractThe oceans are warming, but it is unclear how marine productivity will be affected under future climate change. In this study we examined a wide range of paleoproductivity proxies along a latitudinal transect (36–58°S) in the SW Pacific during the early Holocene climatic optimum, to explore regional patterns of productivity in a slightly warmer‐

Tectonic Impact on Organic Matter Enrichment in Paleozoic Marine Shales from the Yangtze Block, SW China

Journal of Marine Science and Engineering
The enrichment of organic matter in marine shale is a complex process involving tectonic–sedimentary interactions. The tectonic setting exerts critical control over sediment provenance, marine biota, and subaqueous environmental conditions in shale ...
