After WW1 a considerable amount of war material has been dumped on a shallow sand flat, called "Paardenmarkt", offshore Heist, a few kilometres east of the port of Zeebrugge. The dump site extends over 3 km²; on hydrographic maps it is indicated with a pentagon where neither fishing nor anchoring is allowed by law. The Paardenmarkt has been for years a point of major concern, questions and incertitudes and calls for a detailed and thorough evaluation.
In the past, geophysical "remote-sensing" techniques have been applied to evaluate the extent of the dumped material, with encouraging results. However, the complexity of the question requires an integrated, multi-disciplinary approach blending geophysical, geochemical, biochemical, biological, civil engineering, ecological and economical expertise. Such integrated approach will yield an improved insight in the site, its ecosystem and its potential risks for the shoreline population and the users of the sea.


- Detailed synthesis, analysis and scientific evaluation of all available data related to the study area, in order to make a correct evaluation of the actual dimension of the encountered problems.

- Analysis of possible strategies of scientific research, not only with respect to the characterisation of the buried objects but also to the natural setting of the site (more specific the occurrence of gases, biogenic and/or toxic), and the possible perspectives for continuous monitoring of the area.

- Re-evaluation of the present-day ‘status quo’ policy and the evaluation of different options for possible engineering solutions, which includes the possibility to turn the waste disposal site into a nature conservation area.

- Evaluation of possible strategies related to communication and information transfer in order to meet public concern, in due consultation with the authorities.

- Dissemination and integration into a wider European expertise through project proposals, workshops, and the exchange of logistical, technical and scientific expertise at international level.

Main deliverables expected

- Historical / scientific database of the dump site.
- Strategy for geological, sedimentological, geochemical and biological research and monitoring.
- Estimation of the possible environmental effects of the present situation.
- A list of possible engineering and management options (including rehabilitation into nature conservation area).
- Information brochure for the general public stating the general problem.

Project Partners

A wide expertise has been gathered in the following project group : Renard Centre of Marine Geology (RCMG) - UG (co-ordinator); consulting office Magelas; consulting office G-Tec; TNO Prins Maurits Laboratory (TNO-PML); CEREGE - Université Aix-Marseille III; Marine Biology - UG; Civil Engineering - UG; Institute for Nature Conservation (INC). The participation of the foreign partners (The Netherlands, France) supports an early international approach for such border-transgressing problem.
RCMG, Magelas and G-Tec co-operate closely in the evaluation of optimal strategies for geophysical and geochemical research and monitoring programmes. The Marine Biology group and INC focus on the analysis of different monitoring options for benthos, sea birds and mammals in the study area. CEREGE and TNO-PML are involved in the evaluation and simulation of the migration of gas and pollutants at the site. The Civil Engineering group, RCMG, TNO-PML and INC work together closely on the different aspects of risk evaluation and rehabilitation of the study site.

- The project co-ordinator, the Renard Centre of Marine Geology (RCMG) (Department of Geology and Soil Sciences) of the University of Gent, has 20 years experience in reflection seismic and geophysic surveying. RGMG has built an international reputation in the design and application of original very high-resolution seismic techniques in the marine environment.
