Project at a Glance Contents on the CD ROM
  • Marine aggregates are playing  an important role in the provision of high quality raw materials in construction industry and also for coastal protection.
  • Aggregates are nothing but  the colloidal fraction, which typically contains particles sized between 1 nm and several micrometers.
  • Sand and gravel are the most generally taken aggregates from the seabed.
  • By trailer suction hopper dredgers that are capable of transporting cargoes of up to 9,000 tonnes from offshore.
  • The Aggregates are delivered  into coastal towns and cities direct from the dredge site by ship.
  • It reduces the need for road transport and also confers some environmental advantages.
  • Marine Aggregate dredging for marine minerals has mainly occurred in UK waters for many years.
  • In response to the need the sand and gravel aggregates are used as construction aggregate and for beach replenishment.
  • Existing marine aggregates are licensed in these areas and they would permit removal of about 4.5 million tonnes per year.
  • Nash Bank is one of the main source of marine dredged sand supplier  in the Bristol Channel, and they are supplying up to 900,000 tonnes per year.
  • The small aggregates are then collide and aggregate with other aggregates.
  • An ecosystem approach to management, assigns value to sub zones that drive ecological processes and is one way to achieve preservation of the larger marine ecosystem.
  • Ecosystem management forces us to adopt a holistic view of the components as parts of the system, rather than the reductionist view of single-species management.
  • Data are lacking and qualitative information exists on certain areas.
  • Where species aggregate (wintering, resting, feeding, spawning, breeding, nursery, rearing area or migration routes), this information should be used as an alternative or addition to broad-scale quantitative abundance data.
  • It is difficult to identify the boundaries of such aggregation areas, highly in  mobile species.
