Short summary

30 years of BPR data at Drake Passage are used to investigate the Mf, Mm and Mt long-period tides. Amplitudes of Mf and Mt, and all phase lags, vary over the nodal cycle as in the equilibrium tide. Mm amplitude is almost constant, and so inconsistent at 3σ from anticipation due to energetic non-tidal variability. Most findings agree with a modern ocean tide model. BPR records are superior to conventional tide gauge data in this work due to lower proportion of non-tidal variability.
