A reconstruction of the last 2,000 years BP environmental and oceanographic changes on western margin Spitsbergen was performed using a multidisciplinary approach including fossil assemblages diatoms, planktic benthic foraminifera calcareous nannofossils use geochemistry (X-ray fluorescence spectroscopy, X-ray diffraction). We identified two warm periods (2,000–1,600 1,300–700 BP) that were ass...

HU93030-007 LCF (65o01.390N and 30o14.810W) is a 4.5 m long, giant (11 cm diameter) piston core from 1800 m water depth on the continental slope, south of the Denmark Strait sill. The core sampled acoustically stratified sediments at a site below the Kangerlussuaq Trough. Nine AMS C dates on planktic foraminifera indicate that the core spans 3⁄414 to 28 C ka. The sediments consists of two princ...

A new matrix-matched reference material has been developed – NFHS-2-NP (NIOZ Foraminifera House Standard-2-Nano-Pellet) with element mass fractions, and isotope ratios resembling that of natural foraminiferal calcium carbonate. 180–355 µm size fraction planktic foraminifera was milled to nano-particles pressed pellets. We report information values for fractions forty-six elements measured by si...

Earth’s climate cooled markedly during the late Miocene from 12 to 5 million years ago, with far-reaching consequences for global ecosystems. However, driving forces of these changes remain controversial. A major obstacle progress is uncertainty over role played by greenhouse gas radiative forcing. Here we present boron isotope compositions planktic foraminifera, which record carbon dioxide cha...

Abstract. During the early part of last glacial termination (17.2–15 ka) and coincident with a ∼35 ppm rise in atmospheric CO2, sharp 0.3‰–0.4‰ decline δ13CO2 occurred, potentially constraining key processes that account for deglacial CO2 rise. A comparable δ13C has also been documented numerous marine proxy records from surface thermocline-dwelling planktic foraminifera. The recorded foraminif...
