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.Nato Science Partnership Subseries: 2, Environmental Security,1389-1839 ;59Life sciencesEnvironmental sciencesAquatic ecology OceanographyGeochemistryEcology Life Sciences, generalhttps://scigraph.springernature.com/ontologies/product-market-codes/L00004Environmental Science and Engineeringhttps://scigraph.springernature.com/ontologies/product-market-codes/G37000Freshwater & Marine Ecologyhttps://scigraph.springernature.com/ontologies/product-market-codes/L19066Oceanographyhttps://scigraph.springernature.com/ontologies/product-market-codes/G25005Geochemistryhttps://scigraph.springernature.com/ontologies/product-market-codes/G14003Ecologyhttps://scigraph.springernature.com/ontologies/product-market-codes/L19007Life sciences.Environmental sciences.Aquatic ecology .Oceanography.Geochemistry.Ecology .Life Sciences, general.Environmental Science and Engineering.Freshwater & Marine Ecology.Oceanography.Geochemistry.Ecology.570Gray Jedthttp://id.loc.gov/vocabulary/relators/edtAmbrose Jr Williamedthttp://id.loc.gov/vocabulary/relators/edtSzaniawska Annaedthttp://id.loc.gov/vocabulary/relators/edtNATO Advanced Research Workshop on Biogeochemical Cycling in Marine Sediments(1997 :Hel, Poland)BOOK9910479992403321Biogeochemical Cycling and Sediment Ecology2058287UNINA01041nam a2200301 i 450099100317550970753620021205143530.0020130s1996 it b 000 0 ita d8826311137b11765719-39ule_instPARLA221138ExLDip.to Scienze Pedagogicheitaitafre155.334David, Christian155840La bisexualité psychiqueItalianoLa bisessualità psichica /Christian DavidRoma :Borla,c1996389 p. ;21 cmTit. orig.: La bisexualité psychique : essais psychanalytiquesInclude bibliografiaSessoPsicologia.b1176571902-04-1409-12-02991003175509707536LE022 155 DAV01.0112022000015783le022gE30.99-l- 01010.i1201146009-12-02Bisexualité psychique45882UNISALENTOle02201-01-02ma -itait 31
