(Danish).3 It was, however, ascertained that there is a great difference between the velocities of the glaciers in winter and in summer.
The empirical data on which the hydrodynamical investigations are based are: (I) observed velocities and directions of oceanic currents and drifts; (2) salinity; (3) density; (4) temperature of the sea water in situ; (5) oceanic soundings.
The velocities in air and water being respectively 1090 and 4700 ft.
The velocities in unit field-he takes to be 1 3 X300 for the positive, and I.
The result has been that wind velocities published in many official publications have of ten been in error by nearly 5 0%.
