These canyons induce perturbations in the slope current circulation, causing deviations of its flow coastwards the coast (Maso el al.
Buoy D2 followed the main trajectory of the slope current while Buoy D4 derived toward offshore areas.
Highest organism concentration was at the eastern margin of the slope current, which coincided with the most intense salinity gradient detected in the study (Fig.
Physical data showed that the slope current was influenced by the Rhone River runoffs because of the fresh water that characterized this current.
The intrusions of the western branch of the slope current into the canyon, have been explained in terms of the conservation of potential vorticity by Maso er al.
The highest abundances of copepod nauplii were recorded in the eastern margin of the slope current, close to the shallow salinity gradient, influenced by the Rhone river runoffs over the slope current water during the study period.
