Environmental changes of the last three centuries indicated by siliceous microfossil records from the southwestern Baltic Sea

Autor: Tim Brand, Elinor Andrén, Graham Shimmield

Publikováno v: The Holocene. 9:25-38

Four short sediment cores from the southwestern Baltic Sea were analysed with respect to their content of siliceous microfossils. The aim was to detect and date changes in the composition of the diatom flora and to link these changes to variations in

Heavy-metal enrichment in surficial sediments in the Oder River discharge area: source or sink for heavy metals?

Autor: Graham Shimmield, Thomas Leipe, Thomas Neumann

Publikováno v: Applied Geochemistry. 13:329-337

The Oder river drains a highly polluted industrial area and enters the Baltic Sea through a system of shallow lagoons. Surficial sediments in the discharge area of the Oder are highly enriched in heavy metals compared to their preindustrial backgroun

Recent changes in climate in the far western equatorial Pacific and their relationship to the Southern Oscillation; oxygen isotope records from massive corals, Papua New Guinea

Autor: Graham Shimmield, Anthony E. Fallick, Colin P. Chilcott, A. N. Dalgleish, Alexander W. Tudhope, Matthew Jebb

Publikováno v: Earth and Planetary Science Letters. 136:575-590

The western equatorial Pacific warm pool is believed to be the source region of a substantial proportion of the world's inter-annual climate variability, including the globally significant El Nin˜o-Southern Oscillation. Here new data are presented o

The benthic geochemical record of late Holocene carbon flux in the northeast Atlantic

Autor: Tim Brand, George D. Ritchie, Graham Shimmield

Publikováno v: Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences. 348:221-227

This study centered around a transect of high-resolution (multi) cores from the 20° W meridian, 60-18° N in the northeast Atlantic. It spans a range of primary productivity zones, and was used to quantify and examine the vertical flux of organic ca

The impact of marginal ice zone processes on the distribution of 21OPb, 21OPo and 234Th and implications for new production in the Bellingshausen Sea, Antarctica

Autor: T.W. Fileman, George D. Ritchie, Graham Shimmield

Publikováno v: Deep Sea Research Part II: Topical Studies in Oceanography. 42:1313-1335

The vertical distributions of 21OPb, 210Po and 234Th in both dissolved and particulate phases of seawater were measured at five stations along the 85°W meridian in the Bellingshausen Sea, Antarctica. Sea-ice conditions during the expedition ranged f

Lack of enhanced preservation of organic matter in sediments under the oxygen minimum on the Oman Margin

Autor: Graham Shimmield, N.B. Price, Thomas F. Pedersen

Publikováno v: Geochimica et Cosmochimica Acta. 56:545-551

The impingement of oxygen minima on continental margins is widely thought to promote the accumulation of sedimentary facies enriched in well-preserved organic matter. It is shown here, however, that such a relationship does not clearly apply to the p

Forcing mechanisms of the Indian Ocean monsoon

Autor: David W Murray, Graham Shimmield, Warren L. Prell, Steven C. Clemens, Graham P. Weedon

Publikováno v: Nature. 353:720-725

Sediments in the Arabian Sea provide biological, biogeochemical and lithogenic evidence of past changes in the Indian Ocean summer monsoon winds. For the past 350,000 years, this system has been externally forced by cyclical changes in solar radiatio

A 350 ka history of the Indian Southwest Monsoon—evidence from deep-sea cores, northwest Arabian Sea

Autor: Graham Shimmield, Stephen R. Mowbray, Graham P. Weedon

Publikováno v: Transactions of the Royal Society of Edinburgh: Earth Sciences. 81:289-299

The Indian summer Southwest Monsoon plays an important part in influencing, and regulating, the productivity and sedimentation in the northwest Arabian Sea at the present day, by driving coastal upwelling. This leaves permanent sedimentological and g
