In this work we present a new phosphate–water oxygen isotope fractionation equation based on oxygen isotopes determined on fish raised in aquariums at controlled temperature and with monitored water oxygen isotope composition.

The new equation reveals a similar slope, but an offset of about 2‰ to the earlier published equations.

The Faculty of Mathematics and Natural Sciences is divided into eight departments, namely Mathematics, Physics, Chemistry, Pharmacy, Biology, Geography, Geosciences, and Marine Sciences.

Strong discrimination of unwanted ions results in low background count rates in the detector, equivalent to an apparent age of 75000 years at present, in spite of the open architecture.

Routine measurements since late January 1996 (to late May 1996) have dated 127 unknown samples, mostly foraminifera.

The Department of Physics Education is situated at the Leibniz Institute for Science and Mathematics Education (IPN).

Please refer to the department’s website (in German) for further information.

This paper presents high precision paired C age determinations on pristine coral samples that enable us to extend the radiocarbon calibration curve from 12,000 to 50,000 years before present.

We developed a statistical model to properly estimate sample age conversion from radiocarbon years to calendar years, taking full account of combined errors in input ages and calibration uncertainties.

Radiocarbon dating is the most widely used dating technique in the world.

Recent advances in Accelerator Mass Spectrometry (AMS) and sample preparation techniques have reduced the sample-size requirements by a factor of 1000 and decreased the measurement time from weeks to minutes.

Slightly warmer conditions existed in the Early Bathonian (~ 27.0 °C), while the Kimmeridgian shows the lowest temperatures (~ 24.3 °C).
