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 Old Man and the Sea marlin in "On the Blue Water: A Gulf Stream Letter" ("Esquire", April 1936). Joseph Waldmeir's essay ""Confiteor Hominem": Ernest Hemingway's Religion of Man" is a favorable critical reading of the novel—and one which has defined analytical considerations since. Perhaps the most memorable claim is Waldmeir's answer to the question—What is the book's message? The answer assumes a third level on which "The Old Man and the Sea" must be read—as a sort of allegorical commentary on all his previous work, by means of which it may be established that the religious overtones of "The Old Man and the Sea" are
