Title | Paper, 'On the harmonic analysis of tidal observations of high and low water' by G H [George Howard] Darwin |
Date | 1890 |
Description | Darwin writes: 'Extensive use of the tide-gauge has only been made in recent years, and by far the largest number of tidal records consist only of observations of high and low water (H. and L. W.). Such observations have usually been reduced by determining the law governing the relationship between the times and heights of H. and L. W. and the positions of the moon and sun. This method is satisfactory so long as the diurnal inequalities are small, but it becomes both complex and unsatisfactory when the diurnal inequality is large. In such cases the harmonic notation for the tide is advantageous, and as, except in the North, Atlantic Ocean, the diurnal inequality is generally considerable, a proper method of evaluating the harmonic constants from H. and L. W. observations is desirable.'
