Late Holocene Pollen Record of Environmental Changes in Karimata Strait, Sunda Shelf Region

Indonesian Journal on Geoscience, 2019
Pollen analysis has been conducted on a 90 cm gravity core taken from the Karimata Strait to reveal pollen facies in marine sediment and Late Holocene environmental changes in the central Sunda Shelf region.

Eocene to Miocene U‐Pb Geochronology Evolution of the Rio Grande Rise, Southwestern Atlantic: A Paleoceanographic Approach

Paleoceanography and Paleoclimatology, Volume 41, Issue 8, August 2026.
Abstract The Rio Grande Rise (RGR) is a major submarine feature in the South Atlantic that plays an important role in regional oceanographic dynamics. This study presents new U‐Pb geochronology of sedimentary rocks from the RGR, offering direct age constraints on carbonate and apatite embedded within Fe‐Mn crusts and associated foraminifera fossils ...

Event Deposits Recorded Over the Past 800 kyr in IODP Hole U1433A (South China Sea): Implications of a Revised Methodology for Chronology and Paleoclimate Reconstruction

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Instantaneous event deposits such as turbidites, debrites, and slumps are common and frequently occur in marginal seas. These instantaneous deposits represent seconds to days in duration, and can therefore significantly impact age‐depth models and interpretation of paleoclimate history based on thick sedimentary sequences recovered in deep ...

Marsh development and sea level changes in the Gernika Estuary (southern Bay of Biscay): foraminifers as tidal indicators

Scientia Marina, 2006
The ecological distribution of some species of Foraminifera living in estuaries can be used in the interpretation of former coastal lines. There is a close relationship between tide level and the distribution of particular benthic foraminifer species.

Early deglaciation history of the southeastern Baffin Island shelf (Eastern Canadian Arctic Archipelago)

Journal of Quaternary Science, Volume 41, Issue 5, Page 686-701, July 2026.
ABSTRACT During the last glacial period, the Laurentide Ice Sheet (LIS) was the largest terrestrial ice sheet on Earth. Its evolution since the Last Glacial Maximum profoundly influenced Earth's geodynamics and surface processes. Investigating the past dynamics of the LIS provides critical insights into how contemporary ice sheets may respond to ...

Revisiting the Age of Jurassic Coral Bioherms in the Pieniny Klippen Belt (Western Carpathians) on the Basis of Benthic Foraminifers

Geologica Carpathica, 2019
Coral bioherms of the Vršatec Limestone that formed massive, several tens of meters thick complexes during the Jurassic were important sources of carbonate production, with carbonate sediment exported to deeper parts of the Pieniny Klippen Basin (Western

Recording Kimmeridgian Palaeoclimate Changes Using Biofacial and Isotopic Analyses of Benthic Foraminifers From Normandy (Northwest France)

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract During the Kimmeridgian, the Wealdian Basin experienced several periodic disaerobic events, interpreted as the result of extensive rainfall patterns, high sea level and moderate stratification of the water column. These events are recorded in different regions of UK and France.

Tracing the Migration of Fronts in the Pacific Southern Ocean Across the Mid‐Pleistocene Transition

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract The Southern Ocean is a key driver of global climate variability, yet its dynamics during the Mid‐Pleistocene Transition (MPT; ∼1.25–0.7 Ma) remain poorly understood, especially in the South Pacific sector. The Polar Frontal Zone (PFZ) underwent significant latitudinal shifts during this critical period of climate reorganization.

Morphological abnormalities in benthic foraminifers of the Antalya coast

Micropaleontology, 2008
Many researchers report abnormal testmorphologies in benthic foraminifers and some suggest that anthropogenic pollutionmay be one of the causes for these anomalies. Some species are even used as bioindicators of anthropogenic pollution. However, environmental stress may be exerted by natural factors also, such as hypersalinity, periodical acidification

Rudist and foraminifer assemblages in the Santonian-Campanian sequence of Nanos Mountain (Western Slovenia)

Geologija, 2004
The Santonian-Campanian limestones of Nanos Mountain are mainly characterized by wackestone-packstone with benthic foraminifers, thaumatoporellaceans and rudists.
