Holocene reconstructions of the El Niño–Southern Oscillation (ENSO) provide valuable
perspective on its recent evolution and can be important for assessing its future. Optimal …

Dinoflagellate cysts and planktonic foraminifers have been studied from the
Cretaceous/Tertiary (K/T) boundary interval at El Haria (northwest Tunisia). A high-resolution …

Laboratory experiments with living planktic foraminifers show that the δ 13 C and δ 18 O
values of shell calcite decrease with increasing sea water pH and/or carbonate ion …

The South China Sea is the largest low‐latitude marginal sea on the globe. For a long time,
researchers from various fields have been curious about the sea. For instance, geologists …

Geochemical analyses of the carbonate tests calcified by foraminifera have provided much
of the foundation for reconstructions of past ocean and climate conditions, and for …

Distribution patterns of live planktic foraminifers are examined at two times of the year, late
summer and late winter, through horizontal plankton towing along a NW-SE transect across …

ANALYSES of gases trapped in continental ice sheets have shown that the concentration of
CO2 in the Earth's early atmosphere increased from 180 to 280 ppm during the most recent …

Abstract The Pliocene Epoch (∼ 5.3–2.6 million years ago, Ma) was characterized by a
warmer than present climate with smaller Northern Hemisphere ice sheets, and offers an …

In recent years it has become apparent that the “cool tropic paradox” of Paleogene and
Cretaceous “greenhouse” climates arises because of the diagenetic alteration of tropical …

Laboratory experiments conducted on the multichambered planktic
foraminiferaGlobigerinoides sacculifer are used to determine the effect of symbiont …
