Pelorus Sound is typical of New Zealand coastal locations, i.e. there is a semi-diurnal tide modulated on a spring-neap cycle, generated by the superposition of M2 (lunar, semi-diurnal) and S2 (solar, semi-diurnal) tidal constituents. Other tidal constituents, notably N2 (semi-diurnal, generated by the ellipticity of the moon’s orbit), introduce further modulation, meaning that the spring-neap cycle is not exactly repeated. The tidal range varies between at neap and at spring. (These values are calculated from a sea level time series, July 1997 – February 1998, at Pelorus Sound entrance.) The propagation of this tidal signal into Pelorus Sound has not been well
The Way to the Sea The Way to the Sea The Way to the Sea is a 1936 documentary film about the London to Portsmouth railway line (what is now known as the Portsmouth Direct Line) and its recent electrification. This is prefaced with an historical representation of Portsmouth and the London to Portsmouth road (known in the Roman era as Ermin Street and Stane Street). It was produced by the Strand Film Company. Its music was written by Benjamin Britten and its commentary by W. H. Auden, who also wrote the music and words respectively for the similarly themed "Night Mail" that year. The
