Palaeoceanographic proxies as the key to palaeoenvironmentDuring the last decades it became evident that the ocean
forms a major influential factor reacting to global change. The variability
of the thermohaline ocean circulation and of the global carbon cycle,
for instance, largely affect the world's climate. The character and interaction
of processes leading to these climate changes are, however, mostly unknown.
To obtain this information, detailed knowledge of the physical and chemical
characteristics of the different water masses as well as biotic and a-biotic
processes that influence these characteristics is essential.

Alteration of primary proxy signals
by diagenesisThe initial signal of proxies may be altered by secondary
processes such as diagenesis. How to recognise these effects and to obtain
insight as to how diagenesis alters an initial signal, is the central
theme of Part B. The projects belonging to this part focus on the development,
refinement, comparison and testing of different methods that give insight
in the eventual alternation of the proxies studied in projects of Part
A and C.

Development and application of
proxies in earth historyProxies might not always give exact information about
(environmental) parameters. This can, for instance, be due to the incapability
of a proxy to function in a non-analogous situation. Furthermore, studying
long time intervals requires the development of proxy indicators for processes
covering longer time spans. The main subject of the projects mentioned
in Part C is to test and adjust the applicability of several proxies developed
in Part A and Part B to
pre-Quaternary times and to develop new proxies required to study long-term
processes.
