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
Convention Relating to the Distribution of Programme-Carrying Signals Transmitted by Satellite Convention Relating to the Distribution of Programme-Carrying Signals Transmitted by Satellite The Convention Relating to the Distribution of Programme-Carrying Signals Transmitted by Satellite was opened for signature on 21 May 1974 in Brussels and entered into force on 25 August 1979. It is overseen by the United Nations Committee on the Peaceful Uses of Outer Space. Convention provides for the obligation of each Contracting State to take adequate measures to prevent the unauthorized distribution on or from its territory of any programme-carrying signal transmitted by satellite. As of 2014, the convention has been ratified by 37 states; there are 10
