The Atlantic Meridional Overturning Circulation as productivity regulator of the North Atlantic Subtropical Gyre
Spatially extensive and intense phytoplankton blooms observed off Iberia, in satellite pictures, are driven by significant nutrient supply by upper-ocean vertical mesoscale activity rather than by horizontal advection by coastal upwelling. Productivity of oligotrophic regions is still poorly depicted by discrete instrumental and model data sets. The paleoproductivity reconstructions of these areas represent the mean productivity over long periods…
Radiocarbon Measurements of Small-Size Foraminiferal Samples with the Mini Carbon Dating System (Micadas) at the University of Bern
Radiocarbon ( 14 C) measurements of foraminifera often provide the only absolute age constraints in marine sediments. However, they are often challenging as their reliability and accuracy can be compromised by reduced availability of adequate sample material. New analytical advances using the MIni CArbon DAting System (MICADAS) allow 14 C dating of very small samples, circumventing size limitations inherent to conventional 14 C measurements with …
Impact of lateral transport on organic proxies in the Southern Ocean
Lateral transport of fine-grained organic carbon particles can complicate the interpretation of paleoclimate records based on organic proxies. Here we investigated the effect of lateral transport on newly developed temperature and soil organic matter proxies, TEX 86 and BIT index, respectively, in core MD88–769 recovered from the South East Indian Ridge. Our results show that TEX 86 and BIT records in comparison to diatom and foraminifera records…
Sea-level and deep water temperature changes derived from benthic foraminifera isotopic records
A 1000-year high precision record of δ 13 C in atmospheric CO 2
We present measurements of the stable carbon isotope ratio in air extracted from Antarctic ice core and firn samples. The same samples were previously used by Etheridge and co-workers to construct a high precision 1000-year record of atmospheric CO 2 concentration, featuring a close link between the ice and modern records and high-time resolution. Here, we start by confirming the trend in the Cape Grim in situ δ 13 C record from 1982 to 1996, and…
