Clearly the need exists for detailed, site-specific studies of the trace of 

 the P.M.T. in eastern Australia. Mangroves and related vegetational envi- 

 ronments provide potentially useful depositional facies for this purpose as 

 they bear a definable relationship to mean tide level. They are also likely 

 to contain fossil material which is distinctive and suitable for radiocarbon 

 dating. Facies samples collected by drilling and shown by palynological tech- 

 niques to be of intertidal origin provide the basis for the reconstruction of 

 Holocene transgressive sea-level at Missionary Bay. (Authors).

 Level Weather," Review of Geophysics . Vol 6, No. 2, pp 129-174. 



Analysis of sea- level and weather records by frequency is done by the 

 usual methods of spectrum analysis, whereupon a regression analysis is per- 

 formed in each frequency band. The very complete array of existing statisti- 

 cal procedures, for testing hypotheses and allocating confidence intervals, is 

 then available, suitably modified to take account of the fact that the regres- 

 sion coefficients are complex numbers. Associated statistics, such as partial 

 and multiple coherences and residual spectral matrices, may be treated simi- 

 larly. The combination of estimates from neighboring frequency bands is also 

 discussed. 



These methods are used to study records of sea-level, surface atmo- 

 spheric pressure, and wind components at Kwajalein and Eniwetok in the 

 Marshall Islands. An 8 x 8 spectral matrix of these variables covering the 

 frequency range of to 0.85 cycles per day is the starting point for the 

 study. The spectra are characteristic of other sea- level and weather spectra 

 at islands in low latitudes. There is good coherence between the two islands, 

 especially in sea- level and atmospheric pressure. At each island there is the 

 usual strong coherence between sea- level and pressure, with moderate coherence 

 between sea-level and wind at each island. Several regression models of sea- 

 level on the weather records are considered in order to study oceanic influ- 

 ences on the sea- level records free from local weather noise. However, the 

 spatial coherence of the residual sea- level is less than that of the original 

 sea-level records, apparently because most of the original spatial coherence 

 results from coherent weather patterns and not from coherent water motions. 

 If the computed statistical relations are taken as the true relations, the re- 

 sults are not compatible with a simplified theory of free planetary barotropic 

 waves on the surface of an ocean of constant depth. Because of statistical 

 uncertainty, however, little can be deduced regarding the presence or absence 

 of planetary waves. (Authors).

Geohistory reconstructions based on well data provide a direct and quan- 

 titative method of estimating basement subsidence. Geohistories , in addition 

 to responding to rates of sediment accumulation and to local and regional 

 subsidence mechanisms, also reflect eustatic sea-level changes. We have
