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

open access: yes, 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).

Shallow water foraminifera from Niue and Beveridge Reef (South Pacific): insights into ecological significance and ecosystem integrity

open access: yesRoyal Society Open Science
Niue represents one of many important steppingstones facilitating the dispersal of marine organisms across the tropical Pacific Ocean. This study is part of a collaborative expedition involving National Geographic Pristine Seas, the government of Niue ...

Ash grains of the 1991 Mt. Pinatubo eruption as a tracer in Rose Bengal stained deep sea agglutinated foraminifera: How old is Freddy? [PDF]

open access: yes, 2001
The use of volcanic ash particles (including dark-coloured grains) by agglutinated foraminifera that survived the 1991 eruption of Mt Pinatubo volcano provides a useful tracer to help determine growth rates and longevity in the deep sea. In the case of a

Radiocarbon Date List X: Baffin Bay, Baffin Island, Iceland, Labrador Sea, and the Northern North Atlantic

open access: yes, 2004
Date List X contains an annotated listing of 213 radiocarbon dates determined on samples from marine and terrestrial environments. The marine samples were collected from the East Greenland, Iceland, Spitzbergen, and Norwegian margins, Baffin Bay, and ...

Selknamella: a new agglutinated foraminiferal genus from the early Eocene southern high latitudes [PDF]

open access: yes, 2014
A new, unusual agglutinated foraminifera, Selknamella basketi n. gen., n. sp. is described from the Fuegian lower Eocene, Magallanes Basin, southernmost South America.

Foraminifera Fauna in the Core Sediments of the Ulleung Basin, East Sea (Sea of Japan) of Republic of Korea

open access: yesDiversity
Foraminifera are unicellular protists with external shells (tests) that may be calcareous (porcelaneous or hyaline), agglutinated, or organic-walled. Their test morphology and as-assemblage composition closely track environmental forcing, making them ...

Post Cretaceous/Paleogene boundary recovery of the deep marine ecosystem recorded by benthic foraminiferal morphogroups

open access: yesActa Palaeontologica Polonica
The uppermost 2 meters of the Maastrichtian Scaglia Rossa Fm. (Gubbio, Italy) record a notable change in the proportions of morphogroups of deep-water agglutinated foraminifera beginning about 1.4 m below the boundary, where we observe a gradual decrease

Response of deep-water agglutinated foraminifera to dysoxic conditions in the California Borderland basins [PDF]

open access: yes, 1995
Analysis of agglutinated benthic foraminifera from surface samples collected in the San Pedro and Santa Catalina Basins reveals a predictable relationship between the proportions of morphogroups with decreasing bottom water oxygen levels and with the ...

Tracking Agulhas Leakage in the South Atlantic Using Modern Planktic Foraminifera Nitrogen Isotopes

open access: yesGeochemistry, Geophysics, Geosystems
Seawater transported into the South Atlantic from the Indian Ocean via “Agulhas leakage” modulates global ocean circulation and has been linked to glacial‐interglacial climate cycles. However, constraining past Agulhas leakage has been a challenge.
