View source for Example: Maximum Increase of Salinity in the Ems Estuary

[[de: Beispiel: Maximale Zunahme des Salzgehalts in der Außenems]]
The figure shows maximum increase of salinity for a vertical section along the cross profile Ostfriesisches Gatje Nord (in the area of the Außenems). The vertical is superelevated by a factor of 200. The [[period of data analysis]] is two days.

Extreme values for increase of salinity (more than 5 PSU per hour) have been calculated for the deep [[channel]] in the left part of the figure. Increase of salinity in one place is influenced by several processes: horizontal and vertical advection of salinity as well as vertical and horizontal turbulent mixing. Actual rates of change are mainly caused by local horizontal gradients of salinity in combination with strong current velocities.

The spatial variation for the maximum increase of salinity differs significantly from the variations found for the [[Example: Maximum Decrease of Salinity in the Ems Estuary|maximum decrease of salinity]]. This is mainly due to different ebb- and [[flood]] flow-profiles (in horizontal as well as vertical direction) as well as to the path taken by the outflow of less saline fresh water from the [[estuary]].
