BP using coral samples from our offshore coral reef core collections from Barbados (13.10°N; 59.32°W) in the western tropical Atlantic and Kiritimati Atoll (1.99°N, 157.78°W) in the central equatorial Pacific, and from the uplifted reefs of Araki Island (15.63°S; 166.93°E) in the western Pacific.

Arguably, few research topics engage so many different fields of science and have such a profound impact on our understanding of Earth and Solar science as the history of C in the Earth's atmosphere and the surface and deep oceans.
Over the past decade we have witnessed a remarkable development and proliferation of accelerator mass spectrometers; these instruments have reduced the counting time by a factor of 100 and reduced the sample size by a factor of 1000 compared to the classic B-counting systems.
It is estimated that nearly 90% of all measurements made at the more than 50 active accelerator mass spectrometry laboratories are radiocarbon dates.
This dramatic increase in the number of radiocarbon dates is driving the demand for a radiocarbon calibration program that spans the entire radiocarbon timescale from the present to 55,000 years BP.
Of practical importance to a wide range of scientific disciplines is the radiocarbon calibration, which is used for converting radiocarbon ages to calendar years; essential for measuring time and rates of change for numerous scientific fields.
