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
Protocol relating to the status of refugees (1967) Protocol relating to the status of refugees (1967) The protocol relating to the status of refugees of 1967 broadens the definition of the Convention Relating to the Status of Refugees of 1951. The main point of the protocol was to "grant all refugees the same status irrespective of the effective date of the 1st of January 1951." The protocol was completed on the 31st of January 1967 in New York City. Switzerland ratified the protocol on the 20th of May 1968. Germany ratified it on the 5th of November, 1969, and Austria ratified it on the 5th of September 1973.
