Northeastern Atlantic benthic foraminifera during the last 45,000 years: Changes in productivity seen from the bottom up [PDF]
, 1995 We studied benthic foraminifera from the last 45 kyr in the >63 mu m size fraction in Biogeochemical Ocean Flux Studies (BOFS) cores 5K (50 degrees 41.3'N, 21 degrees 51.9'W, depth 3547 m) and 14K (58 degrees 37.2'N, 19 degrees 26.2'W, depth 1756 m), at ...

Coccolithophore biodiversity controls carbonate export in the Southern Ocean [PDF]
, 2020 Southern Ocean waters are projected to undergo profound changes in their physical and chemical properties in the coming decades. Coccolithophore blooms in the Southern Ocean are thought to account for a major fraction of the global marine calcium ...

Sedimentation environment of the Cojimar Formation (Havana province) based on benthic foraminifera
Minería y Geología, 2022 Cojímar Formation, —Lower Miocene (upper part) to Middle Miocene (lower part)—, is a unit in Western Cuba well known for its extensive development and exposure outcrops. It has been widely used in bioestratigraphic studies.

Planktonic foraminifera assemblage composition and flux dynamics inferred from an annual sediment trap record in the central Mediterranean Sea [PDF]
BiogeosciencesThe Sicily Channel, located in the central Mediterranean Sea, represents a key point for the regional oceanographic circulation, as it is regarded as the sill that separates the western and eastern basins.

Chronology for climate change: Developing age models for the biogeochemical ocean flux study cores [PDF]
, 2004 We construct age models for a suite of cores from the northeast Atlantic Ocean by means of accelerator mass spectrometer dating of a key core, BOFS 5K, and correlation with the rest of the suite.

Early Aptian marine incursions in the interior of northeastern Brazil following the Gondwana breakup
Scientific Reports, 2023 This study reports a set of primeval marine incursions identified in two drill cores, 1PS-06-CE, and 1PS-10-CE, which recovered the Barbalha Formation, Araripe Basin, Brazil.

Planktonic foraminiferal assemblages reflect warming during two recent mid-latitude marine heatwaves
Frontiers in Marine Science, 2023 Under future climate scenarios, ocean temperatures that are presently extreme and qualify as marine heatwaves (MHW) are forecasted to increase in frequency and intensity, but little is known about the impact of these events on one of the most common ...

Testing the impact of diagenesis on the delta O-18 and delta C-13 of benthic foraminiferal calcite from a sediment burial depth transect in the equatorial Pacific [PDF]
, 2013 Stable oxygen and carbon isotope (δ18O and δ13C) values measured in foraminiferal calcite are one of the primary tools used in paleoceanography. Diagenetic recrystallisation of foraminiferal calcite can act to reset primary isotopic values but its ...

Upper ocean mixing controls the seasonality of planktonic foraminifer fluxes and associated strength of the carbonate pump in the oligotrophic North Atlantic [PDF]
Biogeosciences, 2015 Oligotrophic regions represent up to 75% of Earth's open-ocean environments. They are thus areas of major importance in understanding the plankton community dynamics and biogeochemical fluxes.

Pliocene and Pleistocene chronostratigraphy and paleoenvironment of the Central Arctic Ocean, using deep water agglutinated foraminifera [PDF]
, 1998 Deep-water agglutinated foraminifera (DWAF) were studied from Cores PS2177-5, PS2200-5, PS2212-3 and PS2185-6; from the R/V POLARSTERN ARK-VIII/3 Cruise in the central Arctic Ocean.
