Multiproxy analyses (including benthic and planktonic foraminifera, δO and δC records, grain-size distribution, ice-rafted debris, XRF geochemistry and magnetic susceptibility) were performed on a C-dated marine sediment core from Storfjordrenna, located off of southern Svalbard. The sediments in the core cover the termination of Bølling–Allerød, the Younger Dryas and the Holocene and reflect g...

[1] Methyl chloride (CH3Cl) is a naturally occurring, ozone-depleting trace gas and one of the most abundant chlorinated compounds in the atmosphere. CH3Cl was measured in air from the Taylor Dome ice core in East Antarctica to reconstruct an atmospheric record for the Holocene (11–0 kyr B.P.) and part of the last glacial period (50–30 kyr B.P.). CH3Cl variability throughout the Holocene is str...

A continuous 48,000-year-long paleoecological record from Neotropical lower montane forest reveals a consistent forest presence and an ice-age cooling of approximately 5 degrees to 9 degrees C. After 30,000 years of compositional stability, a steady turnover of species marks the 8000-year-long transition from ice-age to Holocene conditions. Although the changes were directional, the rates of co...

The winter climate of Europe and the Mediterranean is dominated by the weather systems of the mid-latitude storm tracks. The behaviour of the storm tracks is highly variable, particularly in the eastern North Atlantic, and has a profound impact on the hydroclimate of the Mediterranean region. A deeper understanding of the storm tracks and the factors that drive them is therefore crucial for int...

Abstract. The Northeast Greenland shelf is highly sensitive to climate and ocean variability because it swept by the East Current, which, through western Fram Strait, forms main pathway of export sea ice cold water masses from Arctic Ocean into North Atlantic Ocean. In order reconstruct Current general palaeoceanographic conditions in area during Holocene, we carried out benthic foraminiferal a...

[1] Magnesium/calcium ratios in benthic foraminifera (Cibicidoides pachyderma) from a sediment core on the Laurentian Slope (1854 m) exhibit strong millennial-scale fluctuations during the past 4000 years. We convert these data to seawater paleotemperatures using a new monospecific linear equation. Results suggest that the temperature of upper North Atlantic Deep Water (dominated by Labrador Se...

Understanding the interaction of ocean eddies with tropical cyclones is critical for improving the understanding and prediction of the tropical cyclone intensity change. Here an investigation is presented of the interaction between Supertyphoon Maemi, the most intense tropical cyclone in 2003, and a warm ocean eddy in the western North Pacific. In September 2003, Maemi passed directly over a pr...

[1] Global upper ocean evolution in the Holocene is studied in two coupled ocean-atmosphere models under orbital forcing conditions at 3, 6, 8, and 11 ka. The annual mean sea surface temperature (SST) changes in the early to mid-Holocene are found to be forced mainly by the annual mean insolation forcing with an overall symmetric response of colder equator (<0.5 C)/warmer high latitudes (<0.4 C...

Pollen analyses have been carried out on the infilling deposits of Grotta Romanelli (Apulia, Italy), a reference site for Middle and Upper Palaeolithic Italy. The analysis focused Terre rosse, fine unit till now ascribed to an interstadial phase following Würm acme, uppermost (Terre brune), recently dated latest Late Pleistocene-Early Holocene. Despite diffuse barrenness low pollen concentratio...
