| What do we do? - Training |
This training workshop, was held at the University of Cambridge on 28th to 30th September 2009, focused on the foraminiferal proxies available to reconstruct past variability of ocean chemistry. It aimed at non-specialists in order to develop understanding between scientists dealing with oceanographic proxies, experimental and mesocosm systems and modelling.
The workshop consisted of a mixture of lectures, demonstrations and "hands on" experience in the treatment and sampling of sediment cores, the development of age models, identification and sampling of foraminifera and procedures involved in the determination of stable isotope and trace metal proxies. It demonstrated the fundamentals of proxies and proxy calibrations, the features and limitations of available proxies such as δ18O, δ13C, δ11B, size normalised weight and trace element/Ca ratios (B/Ca, Mg/Ca, Cd/Ca etc.).
