Mathematical Model of 125Sb Transport and Dispersion in the Channelling technique is described and the results discussed. A permanent and average wind-tide situation is used to determine mean trajectories and time scales of retention and evacuation to the North Sea. Comparison with . measurements are satisfactory..Two additional simulations in the case of no wind a

The present study extends this simulation up to 1988 and includes atmospheric deposition following the Chernobyl accident in April 1986. These model simulations are compared with annual observational surveys carried out in the North Sea from 1978 to 1988..Atmospheric models have estimated a dep

Gas Exchange at the Air-Sea Interface: A Technique for Radon Measurements in Seawatere water column..Radon profiles were measured in 4 stations in the NW Adriatic Sea, in September 1990, using solvent extraction and liquid scintillation counting techniques, directly on board the ship. The radiochemical procedure is described in detail. The lower limit of detection is approximately 0

Kinetic models of oceanic trace metal scavenging rely heavily on the information gained from the application of Th nuclides as tracers of oceanic scavenging. The scavenging model of Honeyman and Santschi [1] links the f

234Th: An Ambiguous Tracer of Biogenic Particle Export from Northwestern Mediterranean Surface Waterrom February 1988 through 1989. This site, situated in the central zone of the Ligurian sea, was chosen so that advective inputs from the coast would be minimal. Each sediment trap sample integrated a collection period of 9 to 15 days and was analyzed for radionuclides by non-destructive gamma ray s

Study of the Scavenging of Trace Metals in Marine Systems Using Radionuclidesd using water samples collected in various marine environments. The method consists of measuring the transfer of the corresponding radioactive trace metals from the dissolved to the particulate phase simultaneously with measurements of the uptake of labeled .C bicarbonate, as classically performed f

Lead-210 Balance and Implications for Particle Transport on The Continental Shelf, Mid-Atlantic Bighural radionuclide Pb-210 (half-life 22 years) can provide important insights concerning the fate of fine particulate matter on the continental shelf. This is because (1) the supply of Pb-210 is dominated by the well-known input from the atmosphere and (2) the removal is dominated by scavenging and p
