Radiocarbon dating sample processed rules consolidating subsidiaries
This field trial is one of the oldest continuous agronomic experiments in the world, which has been running under the same management since 1870 and will therefore allow for the modelling of decades of organic pollutants behavior and soil carbon cycling.
Originally associated with a NERC standard grant (Neotropics 1K) led by Professor Jonathan Holmes at the University College London, this project aims to reconstruct a record of effective moisture by using several elemental and stable isotope analyses of lake sediments and dating techniques including radiocarbon.

Susan Trumbore on the use of radiocarbon as a tracer for carbon cycling in a temperate forest.
This field work took place at the Oak Ridge Reservation of the Oak Ridge National Laboratory in Tennessee, USA. During my Postdoctoral tenure (2006-2009), I continued to apply radiocarbon measurements to the study of carbon cycling, this time in agricultural fields in Montana, and I expanded my training to Paleoclimate research working on projects that involved applying elemental (C, N, Pb) and stable isotope proxies (-alkanoic acids) to the study of regional climate of the Holocene and Late Pleistocene.
In 2006, I joined the Earth and Environmental Sciences Division at Los Alamos National Laboratory in New Mexico, USA as a Postdoctoral Researcher working with Dr. These Paleoclimate projects utilized bog sediments and lacustrine sediments collected in northern New Mexico.
Graphitization of samples (reduction of COcan be a cost-effective and relatively easier and faster method to make graphite targets, with minimal resources and time needed.

This has been a significant advance in the NRCF capability eliminating the need to reject samples due to “small size”.
