- NIVA-rapport 
A one month measurement series of ADP data with some additional hydrographic data, including historical observations from 1972, are presented. The current measurements were performed in November 2003, near the main process water discharge at the Mongstad refinery. The bottom-mounted ADP measured currents from about 50 m depth and upwards to the surface in 1 m depth bins, at a sampling rate of 15 minutes. The main feature of the results is a dominating flow towards W-SW that only intermittently switches direction towards NE. This was most predominant in the upper layers as the stability factor increased from ca. 0.15 near bottom to 0.53 at 5 m depth. Average current speed increased from ca 6 cm/s near bottom to ca. 10 cm/s near the surface. The data are being further used in dispersion studies by Statoil.
