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

Global deposition and transport efficiencies of radioactive species with respect to modelling credibility after Fukushima (Japan, 2011)

“…This is expected, as gamma measurements are usually biased when concentrations are close to the respective detection limits (e.g. Evangeliou et al, 2011). The NMB in all four stations ranged between 7 and 40% for 137 Cs and between À11 and 25% for 134 Cs (Table 2) with more than 90% of the values to be within a factor of two (F2) from the observations.…”

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).…”

Vertical and horizontal particle transport in the coastal waters of a large lake: An assessment by sediment trap and thorium-234 measurements

“…In shallow waters, the integration depth is less obvious [Moran et al, 2003]. However, most shallow water studies include the entire water column with the implicit understanding that 234 Th is removed by both newly formed downward settling particles and resuspended particles [e.g., McKee et al, 1984;Waples and Orlandini, 2010;Evangeliou et al, 2011].…”
