it should be driven towards the eastern side of the fjord by the Earth's 

 rotation, as we found it. If we assume that the velocities of this outward 

 motion were greatest near the bottom, it would also explain the inclination 

 of the isopycnals, at the higher levels between Stat. 29 and Stat. 28 

 (Fig. 28), but the distribution of density near the bottom does not indicate 

 any such rapid motion in the deep layers. If we assume that there was 

 lateral equilibrium in our section (Fig. 28), and we compute the velocities 

 by the simple method described by me [1913, p. 49], we find the following 

 differences of velocity (along the components perpendicular to the section): 

 between 130 metres and 



the Surface 18.9 cm. per second 



20 metres 23.0 



50 8.3 



100 0.4 



The components of these relative movements were directed south- 

 eastwards. As the component at 100 metres, though small, also was direc- 

 ted south-eastwards, according to these computations, it does not indicate 

 that there could have been any rapid northward movement at that depth. 



If there really was lateral equilibrium in the section, the vertical di- 

 stribution of density would rather indicate that between Stats. 29 and 28 

 the water was running southwards with a velocity at the surface of about 

 19 cm. per second, and at 20 metres with a velocity of about 23 cm. per 

 second, while along the western side of the fjord, between Stats. 27 and 

 28 it was chiefly running in the opposite direction with the following velo- 

 cities, provided that the motion at 130 metres was negligible: 



At the Surface 46.4 cm. per second 



20 metres 25.0 



50 4.4 



80 2.5

These values do not seem probable, especially not the high velocity 

 of the outward flowing current at the surface, although at that hour (Aug. 

 10, 3.50 p. m.) the tidal current was probably running out of the fjord. 

 If we assume that the difference between high-water at this place and the 

 transit of the moon across the Greenwich meridian, is about i hour and 30 

 minutes, there should have been high-water about 12.14 a. m. (central 

 European time) on August loth, and the water would be running out at 

 3 50 p. m. But this would not explain that the water was running in at 

 Stat. 29, at 6.10 p. m., as low-water would not occur before about 6.30 p. m.
