Considerable research on the physics and biology of the physical boundaries defining these discontinues has been accomplished (see [I D. The interface between water and sediment is the largest physical boundary in the ocean, but has not received a proportionate degree of attention. The purpose of the Nato Advanced Research Workshop (ARW) was to focus on soft-sediment systems by identifying deficiencies in our knowledge of these systems and defining key issues in the management of coastal sedimentary habitats. Marine sediments play important roles in the marine ecosystem and the biosphere. They provide food and habitat for many marine organisms, some of which are commercially important. More importantly from a global perspective, marine sediments also provide "ecosystem goods and services" [2J. Organic matter from primary production in the water column and contaminants scavenged by particles accumulate in sediments where their fate is determined by sediment processes such as bioturbation and biogeochemical cycling. Nutrients are regenerated and contaminants degraded in sediments. Under some conditions, carbon accumulates in coastal and shelf sediments and may by removed from the carbon cycle for millions of years, having a potentially significant impact on global climate change. Sediments also protect coasts. The economic value of services provided by coastal areas has recently been estimated to be on the order of $12,568 9 10 y" [3J, far in excess of the global GNP. 410 0$aNato Science Partnership Subseries: 2, Environmental Security,$x1389-1839 ;$v59 606 $aLife sciences 606 $aEnvironmental sciences 606 $aAquatic ecology  606 $aOceanography 606 $aGeochemistry 606 $aEcology  606 $aLife Sciences, general$3https://scigraph.springernature.com/ontologies/product-market-codes/L00004 606 $aEnvironmental Science and Engineering$3https://scigraph.springernature.com/ontologies/product-market-codes/G37000 606 $aFreshwater & Marine Ecology$3https://scigraph.springernature.com/ontologies/product-market-codes/L19066 606 $aOceanography$3https://scigraph.springernature.com/ontologies/product-market-codes/G25005 606 $aGeochemistry$3https://scigraph.springernature.com/ontologies/product-market-codes/G14003 606 $aEcology$3https://scigraph.springernature.com/ontologies/product-market-codes/L19007 615 0$aLife sciences. 615 0$aEnvironmental sciences. 615 0$aAquatic ecology . 615 0$aOceanography. 615 0$aGeochemistry. 615 0$aEcology . 615 14$aLife Sciences, general. 615 24$aEnvironmental Science and Engineering. 615 24$aFreshwater & Marine Ecology. 615 24$aOceanography. 615 24$aGeochemistry. 615 24$aEcology. 676 $a570 702 $aGray$b J$4edt$4http://id.loc.gov/vocabulary/relators/edt 702 $aAmbrose Jr$b William$4edt$4http://id.loc.gov/vocabulary/relators/edt 702 $aSzaniawska$b Anna$4edt$4http://id.loc.gov/vocabulary/relators/edt 712 12$aNATO Advanced Research Workshop on Biogeochemical Cycling in Marine Sediments$f(1997 :$eHel, Poland) 906 $aBOOK 912 $a9910479992403321 996 $aBiogeochemical Cycling and Sediment Ecology$92058287 997 $aUNINA
