On these pages the laboratory methods used by the marine geochemistry group of the Department of Geosciences in the University of Bremen are described. These pages are currently in their juvenile stage, so please do not hesitate to mail alternative methods, errors, references or useful links.

The main objective of the current marine investigations are both porewater and solid phase analysis of sediment material recovered during several cruises with the research vessel METEOR. Published data from these cruises may be accessed through the PANGAEA database system.

In our group, modelling of porewater and sediment interactions and diffusive processes is performed using CoTReM a computer software created for the simulation of one-dimensional transport of solutes and solid phases and their interactions driven by bio-geochemical reactions and thermodynamic equilibria occurring in natural environments.

The second edition of "Marine Geochemistry" edited by Horst D.Schulz and Matthias Zabel has just been published. This book contains all different aspects associated with our marine investigations.

As an addition to brief descriptions of both laboratory and on-board methods in this book, we set up these webpages, which are meant to be subject to discussion and continuous updating.
