Benthos monitoring in the marine environment

The seafloor is a very suitable indicator of stresses on the marine environment and can act as an early warning system. These stresses can originate from natural and/or anthropogenic sources. The condition of the seafloor (physical, chemical and biological) has been shown to modify in response to external influences. For example, organic matter falling to the seafloor may increase oxygen demand in the vicinity and stress and/or kill organisms located therein. Surveys using a variety of tools have been used to assess natural conditions prior to development or to assess the conservation status of an area. The Marine Environment and Food Safety Services Benthic Monitoring Unit is responsible for the review and assessment of existing and proposed activities that may have an influence on the marine environment.
