Disposal Area Monitoring System (DAMOS)Entry ID: gomc_70
Abstract: To date, extensive monitoring has demonstrated that effects of dredged
material disposal are generally only short-term. When monitoring data suggest
unacceptable contamination, management actions can be taken to contain the
sediment. Contaminated sediment can be effectively isolated from the marine
environment by capping with clean sediment and/or placing it in the center of
planned depressions or ... by burying it in-place (Confined Aquatic Disposal [CAD]
cells). We continue to use monitoring data to refine these techniques and
develop new techniques.
To effectively manage disposal events and disposal sites to ensure minimal
environmental impact. We will continue to monitor disposal events and disposal
sites and to develop new techniques for safely disposing of dredged material
unsuitable for unconfined ocean disposal. More effective methods to collect and
measure field bioaccumulation in small benthic organisms. Studies executed by
DAMOS contractors and shared with general public. DAMOS is always ready to
discuss collaboration with others on scheduled Program surveys.
Waterbody or Watershed Names: New England coast, from Long Island Sound to
Purpose: The DAMOS program monitors dredged material disposal sites using an
interdisciplinary approach to understand the interactions between physical,
chemical, and biological parameters that occur following disposal operations
and to assess the impact of disposal on the ambient environment. Questions
addressed include distribution and behavior of dredged material, relation and
recovery process to ... biological succession, how much disturbance to permit at
any one time, quantification of short- and long-term effects, capping issues,
the identification of abnormal events, and others. This information is used to
manage disposal events and the disposal sites to help ensure minimal
