1. How does the ocean move? How did it move in the past? What are the main sources and sinks of elements? What are the processes controlling the distribution of elements in the ocean? How is studying new elements/isotope changing what we know? Themes: Climate, ocean circulation, biogeochemistry, pollution DTP - Oxford1November 26 th, 2015 Oceanography - Key questions

2. Techniques: Modelling ~ groundhog day? DTP - Oxford2November 26 th, 2015 physics biogeochemistry data
