Spatial and temporal distribution patterns of suspended particulate matter and particulate organic carbon in the Saronikos Gulf (eastern Mediterranean, Greece)

POC and particulate 234Th export fluxes estimated using 234Th/238U disequilibrium in an enclosed Eastern Mediterranean region (Saronikos Gulf and Elefsis Bay, Greece) in seasonal scale

“…3). These values are comparable with those observed in similar marine environments of the Mediterranean, such as Thermaikos Gulf (Greece) where TSM was between 100 and 1700 lg L À1 in summer (Muir et al, 2005), whereas another work in Saronikos Gulf showed values between 50 and 1410 lg L À1 for the same period (Krasakopoulou and Karageorgis, 2005). During autumn TSM concentrations varied between 331 and 974 lg L À1 .…”

“…In the area of study we can assume that resuspension is insignificant as particulate 234 Th increased slightly. Moreover, the circulation patterns correspond to domination of wind-driven surface currents (Laskaratos and Kaltsounidis, 1989) with velocities ranging from 0.45 up to 7 cm s À1 (Krasakopoulou and Karageorgis, 2005;Kontoyannis, 2010). Therefore, steady state conditions could be assumed as the net effect of advective and diffusive transports of 234 Th are small compared to uptake of 234 Th on particles and radioactive decay.…”

A preliminary study of particle dynamics in the water column of Saronikos Gulf, Greece, by using Th-234/U-238 disequilibrium approach

“…3). The values are equal to those reported by Krasakopoulou and Karageorgis [35] for the same area. in coastal stations.…”

Trace metal variability, background levels and pollution status assessment in line with the water framework and Marine Strategy Framework EU Directives in the waters of a heavily impacted Mediterranean Gulf

“…10 for the case of Pb. This could be related to the presence of a considerable benthic nepheloid layer (BNL) in these two shallower areas as reported by Krasakopoulou and Karageorgis (2005) and Evangeliou et al (2011) due to sediment resuspension taking place throughout the year. In addition, the sediments of these areas have been severely polluted in the past and extremely high metal content has been reported (Papakostidis et al, 1975;Voutsinou-Taliadouri, 1981;Scoullos, 1981;Angelidis and Grimanis, 1989;Grimanis et al, 1994).…”
