The northeasterly trend of the shore line of Peary Land beyond Robeson Channel and the deflecting force due to the earth's rotation tend to preserve, far to the northeastward and partly in the form of a free wave of transmission, the disturbance resulting from the stationary oscillation in the straits.

The tide observations indicate that this disturbance is felt as far as Cape Morris Jesup, where the semidaily range of tide is only 0.38 foot.

At Cape Bryant, northeast of Robeson Channel, the range is 1.07 feet.

These values, taken in connection with the Robeson Channel disturbance, indicate that the time of tide along the coast of Peary Land becomes later as one travels eastward from Cape Bryant.
Owing to the comparatively short distance between Cape Bryant and Cape Morris Jesup, it is probable that at the latter point the crest of the wave transmitted from the southwest will appear to arrive much earlier than will the crest of the wave passing between Spitzbergen Islands and Greenland.

In this way the small size of the semidaily tide at Cape Morris Jesup, as well as its time of occurrence, can be partially explained.
A no-tide point doubtless exists in Lincoln Sea, off Peary Land.
The semidiurnal tidal forces vanish at the Pole and are very small over the entire Arctic Ocean.
