| Abstract: | Evros River is the most important river flowing into the North Aegean Sea (eastern Mediterranean) in terms of freshwater discharge,
and the second largest one of Eastern Europe after the Danube River. Salinity and temperature measurements, together with
suspended particulate matter concentrations were obtained in various depths at 14 stations in the adjacent Alexandroupolis
Gulf during four seasons (June 1998, September 1998, February 1999 and March 2000) in order to investigate the particle dynamics
and distributions in the northern Aegean Sea. Analysis of the collected data, together with particle observations under the
scanning electron microscope and study of satellite images showed that, under certain circumstances driven by the hydrological
and wind regime of the area, the Evros River particulate matter, with the associated pollutants, can be transferred far away
from the estuary and implicitly comprise a hazardous factor for the environmental status of the northern Aegean Sea. This
fact, combined with the future construction of the Burgas-Alexandroupolis pipeline, may cause a negative impact on the studied
natural ecosystem. |
