Distribution of carbonate in surface sediments of the Pacific Ocean [PDF]

, 1976
The distribution of carbonate on the floor of the Pacific has been remapped on the basis of 1313 points from 80 references stored in the World Ocean Sediment Data Bank of Scripps Institution of Oceanography. Percent distribution maps and carbonate versus

Orbital Variability in Grazing Proportion: New Insights From Sedimentary Amino Acid δ15N Records of the Western Equatorial Pacific

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract The carbon sequestration capacity of the biological carbon pump (BCP) is determined by surface ocean carbon fixation and the transportation of fixed carbon to the ocean interior, which is closely linked to the trophic structure of planktonic ecosystem.

Remarks on the type locality and current status of the foraminiferal species Rzehakina epigona (Rzehak, 1895) [PDF]

, 2001
A likely topotype locality is proposed for Rzehakina epigona. As the type specimen of Silicina epigona Rzehak, 1895 is assumed to be lost, we undertook a search for new material in the type area, Zdounky village in Moravia. A single locality provided a

Temperature influence on the carbon isotopic composition of Orbulina universa and Globigerina bulloides (planktonic foraminifera) [PDF]

, 2000
Laboratory experiments with the planktonic foraminifera Orbulina universa (symbiotic) and Globigerina bulloides (nonsymbiotic) were used to examine the effects of temperature, irradiance (symbiont photosynthesis), [CO32-], [HPO42-], and ontogeny on shell

Revealing the Physiological Patterns of Dinoflagellates in North‐Eastern Adriatic Phytoplankton

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Using metatranscriptomics, we have described the annual taxonomic and functional succession of the phytoplankton community in the north‐eastern Adriatic Sea, taking into account the effects of environmental factors on succession. The results obtained in this way represent the first comprehensive physiological characterisation of the phytoplankton ...

Seasonal distribution of genetic types of planktonic foraminifer morphospecies in the Santa Barbara Channel and its paleoceanographic implications [PDF]

, 2003
We present data on the temporal distribution of planktonic foraminifer genotypes (small subunit (SSU) ribosomal (r) RNA gene) and morphospecies (sediment traps) collected during 1999 in the Santa Barbara Channel.

A Return to Chalosse Cherts: An Integrated Approach Based on Field Survey, Petrography and Geochemical Analysis to Understand a Palaeolithic Tracer

Geoarchaeology, Volume 41, Issue 1, January/February 2026.
ABSTRACT The Pyrenees have been considered a natural barrier for prehistoric populations. However, in recent years, Palaeolithic research has established connections between the two sides through the analysis of cherts. Among others, the presence of Chalosse cherts in sites on the southern slopes of the Pyrenees has proven the mobility of objects and ...
