A soil chronosequence near Cox Bay, on the west coast of Vancouver Island, British Columbia was investigated. Soils in the sequence have developed on sandy beach deposits, which are advancing toward the ocean at a rate of 0.26 m per year. Dendrochronology and geomorphology established surface ages ranging from 127 to 550 yr for seven selected pedons across these deposits. With soil age, there was progressive deepening and differentiation of genetic horizons, resulting in soil classification that ranged from an Orthic Dystric Brunisol at the youngest site (site 1) to an Orthic Humo Ferric Podzol at the oldest site (site 7). Organic matter increased from a maximum value for mineral horizons of 1.1% in the Bm of site 1 to 4.7% in the Ae of site 7. Oxalate-extractable Al in the uppermost B horizons of the soils increased from 0.12% at site 1 to 0.30% at site 6. Available Mg and K from the lowermost horizons sampled decreased from 35 and 25 mg kg−1 to 4 and 5 mg kg−1, respectively, when moving from sites 1 to 6. Accumulations of organic matter, Fe and Al, and losses of available Mg were plotted against soil age and yielded chronofunctions with exponential solutions.

Thin indurated horizons (placic) were found in coarse textured deposits in the humid west coastal region of Vancouver Island in British Columbia. Four soils representing the range of pan development were studied. The soils were classified as Placic Ferro-Humic, Mini Humo-Ferric, Placic Humo-Ferric, and Gleyed Placic Mini Ferro-Humic Podzols. The soils supported a rather luxuriant vegetative association, with one site exhibiting a bog type of vegetative cover. It was found that the indurated horizons were of two types, namely, those that had high amounts of Fe and those that seemed to concentrate Al. The role of organic matter in the formation of placic horizons is still obscure, although organic matter concentrations were largest in indurated horizons of high aluminum content. The kind of pan should be considered in classifying these soils, as existing criteria do not distinguish between different kinds of pans. In addition, the relatively large amounts of oxalate-extractable Fe and Al to depths up to 300 cm require further study.

Soil Chronosequence

Phosphorus fractionation and analyses for free oxides of Fe, Al and Si were carried out on depth interval samples taken from a sandy soil chronosequence on the west coast of Vancouver Island, British Columbia. The seven profiles sampled ranged in age from 127 yr at Site 1 to 550 yr at Site 7. Calcium-bound phosphate (PCa) decreased in the 0- to 5-cm depth interval samples from 105 mg kg−1 at Site 1 to 2 mg kg−1 at Site 7 and similar but less-pronounced decreases were noted for lower depths. Profile averages of PCa exhibited a linear function with time, whereas exponential trends were noted for the surface 10-cm samples.

AbstractNootka is an historical fur-trading centre in Yuquot, on the west coast of Vancouver Island, British Columbia, Canada. In 1788, the Spanish king Charles III sent an expedition to Nootka commanded by Ignacio Arteaga (1731-1783). A year later, Spain established a military post, San Lorenzo de Nutka, at Yuquot in 1789 which existed until 1795. The missionaries who arrived with the sailors were urged to learn the vernacular languages in order to evangelize. In chapter 5 of the

Oceanographic data collected in a line of stations extending seaward of the west coast of Vancouver Island, British Columbia, were reviewed and analyzed. On the basis of these data and the large-scale meteorological processes of wind, insolation, and precipitation, the characteristic structure of temperature and salinity in the coastal region was denned in five temporal stages throughout the year. These stages are presented as vertical sections along the line with characteristic ranges of values to be found in each of the structural elements.

Twenty-five species of Polychaeta recently collected off the coast of British Columbia are discussed. Most were taken in waters of considerable depth off the west coast of Vancouver Island. Sixteen are new to British Columbia. Most of these are known from farther south on the west coast of North America, but some from much shallower depths than those from which they are now recorded; two of them are new to the northeast Pacific; one is a new subspecies. The other nine have been previously known from British Columbia, but they are now recorded from much greater depths than hitherto, or in new geographical locations.

A New Species

Lampetra macrostoma n.sp., a freshwater parasitic lamprey, is distinguished from related species L. tridentata, L. lethophaga, L. folletti, L. minima, and L. similis by its parasitic habit and very large disc. Other characters distinguishing the species from L. tridentata are its longer prebranchial length, large eye, weakly pigmented velar tentacles, and its ability to remain in freshwater. The recently metamorphosed form readily survives in freshwater and probably is non-anadromous even though it can survive in salt water. The new species has been discovered in two lakes on Vancouver Island, British Columbia, Canada, where it attacks large numbers of resident salmonids. Because of its ability to survive and feed in freshwater, it poses a definite threat to freshwater fishes.Key words: lamprey, new species, non-anadromous lamprey, salmonid parasitism

The presence of larval Anisakis in British Columbia herring was examined during the winter fisheries of 1950–51 and 1951–52. In the commercial catches in the Strait of Georgia the incidence was found to be between 80 and 90%. In Hecate Strait, on the west coast of Vancouver Island and in the mainland coastal area of Queen Charlotte Sound it was between 90 and 100%. The intensity of infection varied greatly in different fishing areas (i.e. in different herring populations). Generally, the maximum level of infection occurred in the Queen Charlotte Sound coastal regions, and decreased both north and south of this area. Fish on the west coast of Vancouver Island were more heavily infected than those on the east coast (Strait of Georgia). The level of infection increased with age, I-year fish (i.e. fish in their first year of life) being uninfected. The intensity of infection remained constant throughout the winter for any particular age and area and was the same for both sexes. In most areas the level of infection was a little lower in 1951–52 than in 1950–51.

Metamorphic Facies

The metamorphic history of the volcanic sequence of the Metchosin Igneous Complex (MIC), an Eocene ophiolite exposed on southern Vancouver Island, British Columbia, Canada, was studied to examine the roles of seafloor and accretion-related processes. Metamorphic facies in the volcanics vary from prehnite–actinolite assemblages in the east to greenschist and amphibolite assemblages in the west. In the east, metamorphism is typified by chlorite ± prehnite ± epidote ± actinolite assemblages that fill vesicles and replace interstitial material; plagioclase is variably albitized, and clinopyroxene is relatively fresh. In the west, the common groundmass assemblage is amphibole + epidote ± chlorite. These assemblages and chlorite geothermometry show a regional east–west gradient of ∼5–10 °C/km that is oblique to the volcanic stratigraphy. The regional metamorphic facies distribution for the MIC volcanics is not consistent with seafloor hydrothermal metamorphism documented for ocean crust from mid-ocean ridges, ocean islands, or island arcs. We speculate that underthrusting of the MIC beneath the Pacific Rim Terrane led to the regional metamorphism of the MIC, and that the change in metamorphic grade from east to west results from regional tilting of the complex, perhaps by orographic effects, during or after accretion.
