Is it a Northern or Southern Island site? I looked at it in the NZ webcam site (www.wn.co.nz). I guess Spring is just around the corner...Sept 22 or so...right? We are gonna get out Fall soon and the temps will drop to 24C or so now. There is a threat of rain in the forecast..but it won't ever rain her again I feel. We have some big fires burning up the areas around me again...near Julian and near Big Bear Lake (again). In fact, the Big Bear fire is the highest priority on the US Federal fire control boards right now.	SurferJoe46 (51)

GLASBY New Zealand Oceanographic Institute Division of Water Sciences Department of Scientific and Industrial Research Private Bag, Kilbimie, Wellington, New Zealand R. L. MOSS Wellington Regional Council P.O. Box 11-646, Wellington, New Zealand P. STOFFERS Geologisch-Palaontologisches Institut University Kiel Olshausenstr. 40/60, D-2300 Kiel Federal Republic of Germany Abstract The <20 urn fractions of 72 sediment samples from Pauatahanui and Porirua Inlets of Porirua Harbour have been analysed for eight elements and the results compared between the two inlets. Co, Ni.Fe, and Mn occur in similar abundances in sediments from the two inlets and show no evidence of contamination. Cr concentration is somewhat higher in sediments from Pauatahanui Inlet and again shows no evidence of contamination. Cu concentration is significantly higher in sediments of Porirua Inlet and two samples taken in the vicinity of Porirua City are in the class uncontaminated to moderately contaminated. Pb and Zn show significantly higher concentrations in sediments from Porirua Inlet. Sediments in the vicinity of Porirua City attain the category moderately to strongly contaminated for Pb and moderately contaminated for Zn. No evidence of heavy-metal contamination is seen in sediments in the vicinity of State Highway 1. Heavy-metal pollution in Porirua Harbour therefore appears to be restricted to Pb, Zn, and, to a lesser extent, Cu, and occurs in Porirua Inlet in the vicinity of Porirua City.

Art. XVII.—Porirua Harbour : a Study of its Shore-line and other Physiographic Features. By G. Leslie Adkin.

The inlet known as Porirua Harbour, a landlocked arm of the sea, is a unique geographical feature of the western coast of south-western Wellington (fig. 1). Along this coast all other indentations are the result of marine abrasion acting more effectively than elsewhere on the weaker sections of the coast, the more resistant portions, which are receding less rapidly under wave-attack, being left to form the intervening promontories and headlands. Marine abrasion has played only a minor part in the shaping of Porirua Harbour—a part, however, that was important in connection with the evolution of the shore-line of that inlet. The outline of Porirua Harbour is characteristic of a drowned area where the sea has penetrated a branching valley-system of somewhat mature topographic development. Two of the principal branches of this valley-system are now occupied by tide-water and constitute the present harbour or inlet, while other former indentations have been reclaimed from the sea by the infilling accomplished by local streams. One of the first to touch on the physiography of the Porirua area and to correlate it with that of Port Nicholson was Dr. J. M. Bell (1910), who expressed the opinion (loc. cit., p. 539) that the surface of a tilted earth-block dips from near the crest of the scarp of the Wellington fault in the direction of Porirua and forms the slope which originally determined the course of the Porirua as a consequent stream. The validity of the first part of this statement is borne out by the existence of a peneplane surface —evidently referable to the Kaukau cycle of Cotton (1912)—which surmounts the valley of the Porirua Stream and slopes towards sea-level in a northerly direction. In the same paper Bell also referred to certain historical proof that the small uplift which affected the district round Wellington City during the 1855 earthquake extended into the Porirua area, inasmuch as the Pahautanui Stream became noticeably less navigable than formerly. – 145 – Thumbnail: [Volume 53, 1921 page 145] View Image Dr. C. A. Cotton in a detailed paper on Wellington physiography (1912) referred to the Porirua area at rather greater length. He dissented from the view held by Bell that the Porirua Stream flows down the back slope of a tilted block, on the grounds that the Porirua occupied its present Picture icon Fig. 1.—Locality map of south-western Wellington, showing places mentioned in text; also the area at Porirua Harbour shown in figs. 4, 5, and 6. valley before the faulting and tilting took place. It does not necessarily follow, however, that the excavation of the Porirua Valley has been accomplished since the faulting and tilting, and that it was not in existence prior to those events. The drowning of the lower reach of the Porirua Stream – 146 – Thumbnail: [Volume 53, 1921 page 146] View Image to form one arm of the present inlet is ascribed by Cotton (loc. cit.' p. 257) to a downward movement of 30 ft. or 40 ft. subsequent to the general movement of elevation of the Wellington Peninsula, but no precise cause of the subsidence is proffered. Cotton also states that “at Porirua there appears to have been little or no movement either up or down in 1855. Raised rock platforms similar to those at Wellington are not found.” I shall be able to show, however, that raised shore-platforms of wave-planed rock do occur along a very considerable part of the Porirua shore-line, and form one of its most conspicuous features. The present writer had occasion to refer to the Porirua area in connection with an apparent deformation of the southern end of the Horowhenua coastal plain (Adkin, 1919, pp. 110–12). The deformation of the coastal plain was ascribed to its intersection by the subsiding, or downward tilting, of the earth-block, bounded east and west probably by flexures, which extends from Port Nicholson to Porirua Harbour, and thence northward past Pukerua inside the Island of Kapiti After a detailed examination of a large portion of the Porirua area the writer sees no reason for any modification of this solution of the problems involved. The Land. Since the present paper has for its main theme the description and interpretation of shore-line features, only the relevant elements of the land-surface of the Porirua district will be discussed, under two headings, as follow: (1.) Topography and Drainage; (2) Influence of Deformation on the Relief. (1.) Topography and Drainage. The country surrounding Porirua Harbour is one of moderate elevation but of high relief. This moderately elevated tract rises to a greater height inland, especially in a north-easterly direction, and consists of a series of fairly even-crested hill-ridges, which for the most part have a N.E. by N.—S.W. by S. trend, though a few of them are orientated more nearly north and south. The ridge-tops are commonly broad and undulating, and the ridges themselves are flanked on either hand by long branching lateral spurs that taper off as they descend to the bottoms of the intervening longitudinal valleys. The principal valleys have flood-plains in their lower portions, and graded bottoms extend practically to their heads. In their upper reaches, however, overlapping spurs are still a prominent feature. The valley-sides are well dissected by the numerous lateral gullies, but this dissection has not everywhere extended to the main ridge-crests, where what seems to be a more mature relict topography still prevails. There is some evidence, in the form of a high-level bench, notably at the head of Taupo Creek and in the valley of the Kahao Stream, of an intermediate partial erosion-cycle, probably corresponding to the Tongue Point cycle of Wellington Peninsula, and in addition to this there are areas of rejuvenation due to coastal recession and other causes. A full consideration of these matters is beyond the scope of this paper, but it may be remarked that, while the topography is undoubtedly composite, indications of the intermediate erosion cycle or cycles have been practically obliterated except in the instances cited above. Broadly speaking, therefore, the topography of the Porirua area may be described as being just past early maturity—that is, in the stage when maximum relief is giving place to more subdued forms. ....and so on....but I can't find where it actually is.....is there something wrong with Google?
