BENTHATRON - Sediment incubation facilities

BENTHATRON -a facility currently under construction- follows the general approach of established ‘cosm’ studies to analyze processes operating in larger natural systems, but is distinguished by the following specific aims:

  • to elucidate the interaction between (natural) chemical and physical conditions of soft sediments and benthic biota,
  • to compare the response of single species of benthic biota and (synthetic) multi-species communities
  • to analyze the role of sediment nutritional value and toxicants sequestered in sediments in structuring benthic community composition

BENTHATRON support the following research lines:

  • Life strategies of benthic invertebrate species in contaminated and disturbed  sediments
  • Structure and function of multi-species associations of attached micro-algae
  • Spatial ecology of soft-bottom communities

A list of completed and running contracts indicates the perspective for a BENTHATRON in commissioned research. A demand for benthic studies is likely since the management of polluted sediments in The Netherlands and abroad is a major issue, especially under the new EU regulations. The availability of BENTHATRON is also likely to strengthen the growing network with fundamental science via the Centre for Wetland Ecology
