Atmospheric CO2 concentration is hypothesized to influence vegetation distribution via tree–grass competition, with higher CO2 concentrations favouring trees. The stable carbon isotope (δ13C) signature of vegetation is influenced by the relative i

We present data for North Atlantic core Biogeochemical Ocean Flux Study (BOFS) 16K (59°N, 23°W, water depth 2370 m) including coccolith flora, ∂18O, planktonic foraminiferal sea surface temperatures (SSTs) by FA20 and SIMMAX methods, and alkenone

Dumping into the open ocean is considered a viable political option to cope with the rapidly increasing global production of municipal sewage sludge. However, before such an option can be justified, the impact of mega-scale dumping upon the marine en

Two techniques for estimating past variations in sea surface temperature (SST) have been used to investigate climatic change in Biogeochemical Oceanic Flux Study (BOFS) core 31K (19°N, 20°W) from the eastern subtropical Atlantic. High-resolution SS

Isotope ratio monitoring gas chromatography–mass spectrometry (irm GC–MS) was used to determine the δ13C values of individual compounds present in organic residues preserved in archaeological potsherds. The lipid fractions of the preserved organ
