“…The scavenged character of Mn was pronounced at all the stations of the N. Aegean, with elevated surface values down to about 100 m depth, a rapid decrease in the intermediate layer and then an increase with depth, probably due to Mn remobilization from sediments. Surface values (44.98 nM) of one order of magnitude higher than those of the intermediate and bottom layers (4.80 nM) were recorded, especially during September (period of increased BSW inflow), suggesting the influence of Black Sea Water that is enriched with Mn (Zeri et al, 2000). Manganese values in the S. Aegean are considerably lower compared with N. Aegean ones, showing relatively enhanced surface values which decrease with depth.…”

The main outputs of a multidisciplinary and integrated studies are summarised. The results incorporate the latest biogeochemical researches, at basin scale, in the Aegean Sea (including thermohaline circulation studies, SPM dynamics, mass and energy fluxes, acknowledge biochemical processes in the euphotic and the benthic layer and benthic response to downward fluxes). The data were acquired within five (seasonal) research cruises, during 1997-1998. Data analysis and evaluation hence provided important new information on the functional processes of the Aegean ecosystem. In terms of water circulation, no new deep water formation in the Aegean Sea was observed, during 1997-1998, but rather intermediate water, due mainly to the mild winter conditions. All the biochemical parameters of the euphotic zone (nutrients, Particulate Organic Carbon (POC), chlorophyll-a, phytoplankton, primary and bacterial production), although high in the N. Aegean Sea reflect clearly the highly oligotrophic character of the Aegean Sea. In the N. Aegean, microbial food web was the main pathway of carbon, whereas in the S. Aegean, the food web could be classified as multivorous. An important Black Sea Water (BSW) signal was observed in the dissolved phase; this was especially pronounced in the Dissolved Organic Carbon (DOC), Mn and to a lesser degree to Cd, Cu and Ni concentrations. The downward material fluxes are higher in the N. Aegean, relative to the S. Aegean. Substantially higher values of near-bottom mass fluxes were measured in the deep basins of the N. Aegean, implying significant deep lateral fluxes of POM. The N. Aegean could be classified as a ''continental margin'' ecosystem, whilst the S. Aegean is a typical ''oceanic margin'' environment. There is a close relationship and, consequently, coupling between the near-bottom mass fluxes and the accumulation rates of organic matter (OM), with the near-bottom mineralisation, bioturbation, redox potential, oxygen consumption rates, the sediment microbiological and enzymatic activity and the meio-macro-and mega fauna abundances in the

“…peak and a box core (SL78BC) from a station in the North Aegean with a high Mn content (up to 326 mol Mn g Ϫ1 ) were collected during the 1999 Smilable cruise in the Mediterranean Sea on the RV Prof. Logachev. The high Mn concentrations in the sediment, more pronounced at the North Aegean than at the Rhodes site, indicate the influence of Black Sea water that is enriched in Mn and enters the North Aegean through the strait of Dardanelles (Zeri et al 2000;Lykousis et al, 2002). The Rhodes site is located at 35.…”

“…This pycnocline limits exchanges between surface and deep water, but is the most active zone of the sea in terms of oceanographic characteristics. Pollutant loadings to the Black Sea have been described by Zeri et al (2000), and Tuncer et al (1998). Rivers and industries along the Turkish coastline were identified as significant sources of Cu and Zn (SUMAE, 1990).…”

Increasing amount of solid waste and wastewaters arising from municipalities and other sources and their consequent disposal has been the source of major environmental problems in Turkey. Geological and geographical formations of the eastern Black Sea coasts of Turkey do not permit appropriate and economical solutions to be found easily for the removal of solid wastes and wastewaters. All of the municipal and industrial solid wastes mixed with hospital and hazardous wastes are dumped to the nearest lowlands and river valleys or directly into the sea. Although major cities have outfalls, most of the settlements in this area dispose of their wastewaters directly into the shallow coastal sea waters. Existing heavy industry in this area dispose of their wastewaters and inorganic toxic materials, either directly into coastal waters or deep anoxic strata, via their outfalls and submarine tailings placements. Solid wastes with their high organic and inorganic strength and quantities are the major polluting substances in comparison with the wastewaters. In this study suitability of an applied solid waste planning system for 22 villages and two major cities along the southeastern Black Sea coastline and environmental problems related to the solid waste and wastewater disposal in this region were discussed.
