Eemian climate change and validation 
of environmental magnetic methods
The acceptance of environmental magnetism critically depends on how well the magnetic proxy parameters are understood and quantified.  Moreover, the considerable analytical merits of mineral magnetic parameters can only be fully exploited when they are calibrated versus more classical analytical tools.
back to top of page Quantification of environmental magnetic methods and inter- pretational procedures is a prominent network goal, and subject of the Utrecht group. 

This MAG-NET project aims at the design, optimisation and validation of environmental magnetism protocols, in close consultance with appropriate network partners. 

The results will be applied to Eemian sediments from Holland and Belgium
 
The Project
The project involves making an inventory of existing environmental magnetic methods and procedures, and selecting the most appropriate ones. It is desirable to design and carry out experiments for further optimization. Close interaction with other network partners is foreseen. The aim is to develop procedures – to be published in scientific journals and on the MAG-NET website – which serve as the future reference for environmental magnetic methods.

The Eemian
The Eemian occurs within the last interglacial, in isotope stage 5e or 5.5, and represents the nearest geological equivalent to present-day climate and environment. The project aims to study how the climate change is magnetically reflected along a marine to continental gradient in a geographically restricted – and thus climatically very similar  – area (Netherlands and immediate surroundings). Samples are already partially available, because the Netherlands Geological Survey Eemian Project has cored lacustrine and shallow marine sediments and plans to take additional cores in the North Sea in the near future. The fully continental equivalent is represented by a loess section just across the Belgian/Dutch border, with a remarkabe completeness claimed to be unique in NW Europe. Currently, a detailed archeological (Neanderthaler) excavation is carried out. Preliminary sampling has been done, additional sampling and high-resolution sampling (where needed) will be done by the postdoc.

A considerable high-resolution data base of geochemical, mineralogical and other geological parameters is already available as well and will be completed in the framework of the Netherlands Geological Survey project. Therefore, this large mineral-magnetic and non-magnetic data base constitutes an ideal case study to cross-calibrate environmental magnetism methodology with other, more conventional methods. This will involve extensive use of multivariate statistical methods.
