TLDR
In this article, the effect of oceanic tides on earth rotation has been investigated and it was shown that the effect is not limited to the North Sea and the 10°-world ocean.Abstract:
The problem of tidal friction as a cause of the secular deceleration of earth rotation was higherto approached on the basis of estimating the kinetic energy dissipated by bottom friction. It would appear however, that in any analysis of the influence of oceanic tides on earth rotation the varying directions of the torques due to tidal streams and acting on the solid earth, must be taken into account. As examples for this, the torques due to tidal friction are calculated for the North Sea and for the 10°-world ocean, applying hydrodynamical-numerical methods. The results show that earth rotation is not retarded at all points of the world ocean, but that tidal areas exist exerting either decelerating or accelerating forces.read more

Tidal Friction in the Irish Sea
TL;DR: In this paper, it is assumed that the energy is dissipated by the viscous drag of layers of water which move parallel to the bottom of the sea, which can in fact be seen marking the surface of the Irish Sea in places where the current runs exceptionally strongly, or over a particularly uneven bottom.

Tidal Friction in Shallow Seas
TL;DR: In this paper, the authors discuss what regions are capable of producing notable parts of the secular acceleration; to estimate as accurately as possible from the data available the dissipation in these regions; and to compare this with that calculated from the mass acceleration, so as to find out whether it is necessary to assume the existence of any other important cause to account for the latter.
