Pollen diagrams from sites in southwest Nova Scotia and close to the New Brunswick – Nova Scotia border show that after retreat of the Wisconsin ice sheets, most tree taxa arrived in the extreme southwest of Nova Scotia earlier than anywhere else in the province. For most tree taxa, arrival times at sites in maritime Canada and in northeastern New England are consistent with very early dispersal of individuals along the coastal strip via the exposed coastal shelf and with their entering Nova Scotia from the southwest. These scattered pioneer populations acted as centres for major population expansions, which followed much later in some cases. Local environments, fire, and interspecies competition appear to have been more important than propagule dispersal rates as factors limiting the spread of most taxa.

Vertical Crustal Movements

A surface depicting linear vertical movements in Maritime Canada was computed from sea-level data recorded by 8 tide guages and 308 mostly disjoint, relevelled segments of the first-order Canadian levelling network. Owing to the sparsity of the available data and their distribution, the velocity surface must be regarded as indicative of the crude features only. The indications are that there is a west-northwest trending belt of faster subsidence across the eastern end of the Bay of Fundy, and that there may be an area of uplift in northeastern New Brunswick. Although the faster subsidence around the eastern Bay of Fundy seems to be well established now, more data are needed to prove or dispel the existence of the indicated uplift.

Age Range

We report single-grain ages for detrital muscovite separated from sandstone samples from five localities in southern New Brunswick and southeastern Cape Breton Island, Nova Scotia, and from two quartzite clasts from a quartzite-pebble conglomerate that underlies the sampled sandstone units in New Brunswick. The oldest detrital grains were found in one of the quartzite clasts; their age range, ca. 650−630 Ma, is defined not only by the single-grain analyses but also by spot dating (using a UV laser) within a single large grain, suggesting that these grains came from a single source. The second quartzite clast has a blastomylonitic fabric with muscovite “fish,” and most of the muscovite ages have been partially reset (at ca. 550 Ma) from the original ca. 650–630 Ma ages. The age distribution plots obtained for the sandstone samples suggest the presence of muscovite that still retains the original source age, but most of the grains have been partially reset by the same ca. 550 Ma event that reset muscovite ages in the second quartzite clast. We suggest that the quartzite source that produced the two clasts was also the source of muscovite in the Avalonian Cambrian rocks of Maritime Canada. The original source rock was likely a metamorphic or perhaps granitic rock unit situated relatively proximal to the site of deposition of the quartzite protolith, but the actual source is not known, and locally, no potential candidates are exposed. The resetting event at ca. 550 Ma may be linked to initial stages of regional transtension associated with rifting of Avalonia from Gondwana.

Vegetation And Climate

ABSTRACT Environmental conditions (vegetation and climate) of Maritime Canada are reconstructed as a regional contribution to a national synthesis on the paleoenvironment of Canada 6000 yr BP. Ten new sites, including three complete sequences and seven short sequences bracketing the 6 ka period, are added to the existing pollen dataset for this region. The vegetation prevalent 6000 yr BP in New Brunswick was a mixed coniferous-deciduous forest with pine, mostly white pine (Pinus strobus) in the northwest, and a mixed coniferous-deciduous forest with hemlock (Tsuga canadensis) in the south and southeast. In the northwest, fir (Abies) replaced pine at high elevations and a boreal forest grew on the New Brunswick Highlands. The dominant vegetation at 6000 yr BP in Prince Edward Island and Nova Scotia was a mixed coniferous-deciduous forest with hemlock dominating. Cape Breton Island was covered by a mixed coniferous-deciduous forest with pine and/or fir, except for the southern part of the Island where hemlock was probably present. Analysis of the fossil sites indicate that a warm-dry period influenced the composition of the vegetation 6000 yr BP.

Horse Fly

Fifty-seven species of Tabanidae are recorded from maritime Canada. Thirty-one species have been collected during the period 1973–1976 in the Maritime Provinces, particularly in the Nova Scotia–New Brunswick border region. Larval and pupal habitats were not determined. Feeding habits of 20 species of tabanids were determined; 15 species were collected feeding on man, and 9 species feeding on cattle. Chrysops mitis was the most abundant deer fly and accounted for 14.5% of the tabanid population, 37.1% of the deer flies collected, and 52.6% of the deer flies feeding on man. Hybomitra epistates was the most abundant tabanid; it comprised 19.7% of the tabanids collected and 32.6% of the Hybomitra population. Hybomitra frontalis was the most abundant horse fly feeding on man, and comprised 74.2% of this group. Chrysops frigidus accounted for 42.9% of the deer flies feeding on cattle, while H. typhus Form A accounted for 50% of the horse flies feeding on cattle. Hybomitra illota was the most abundant tabanid collected in tabanid traps. Generally, species of Chrysops were more annoying to man while species of Hybomitra were more of a pest of cattle. Specimens of Tabanus were uncommon.

The Right

In Canada’s Maritime Provinces, lobster is the food of tourism. Featured in countless guidebooks, cookbooks and restaurant ads, lobster beckons visitors to the region. Later, represented in as many forms as souvenirs, it signifies their trip, offering tangible proof that they have experienced–and tasted–the “real” place. However, as George Lewis (1989) argues is the case in Maine, residents of Prince Edward Island, Nova Scotia and New Brunswick have their own understandings. Here I explore two generalized narratives widespread in Maritime oral tradition: that lobster was used by farmers as fertilizer on fields and that its consumption once was associated with shame, signaling as it did that a family had nothing else to eat. In considering the contested meanings surrounding lobster’s recontextualization from a food of poverty to a regional delicacy, I suggest that Maritimers’ knowledge of lobster’s earlier working class associations, as well as of the “right” way to cook and eat lobster, acts not only as a marker of socio-economic difference but as an indicator of Pierre Bourdieu’s notion of distinction (1984) that is intricately linked to constructions of regional identity.

Cultural Regeneration

This essay analyses visitor attitudes to industrial heritage at a variety of former industrial sites, ranging from former coal mines, shipbuilding yards and steampowered mills to a reconstructed waterfront. In addition, a comprehensive industrial museum provided a venue for further critique of the means by which the industrial past contributes to a regeneration of cultural identity in Maritime Canada. The range of former industrial sites reflects the multiple narratives of deindustrialisation affecting the Canadian provinces of Nova Scotia, New Brunswick and Prince Edward Island for much of the twentieth century while visitor responses to a detailed survey indicate that a focus on industrial heritage is a highly-valued component of respondents’ understanding of the region’s cultural identity. The essay notes, however, that this representation of cultural identity is highly problematic and replete with contradictions, most notably between respondents’ desires for authenticity and the necessarily sanitised landscapes required for cultural tourism. Similarly, designers and managers of industrial heritage may be motivated to construct heritage landscapes which prioritise entertainment and spectacle and down play significant environmental, social and political elements of the former industry. From these examples in Maritime Canada, it is clear that visitors encounter significant complexity in their experience of the industrial past. This complexity provides both opportunity and challenge in the use of the industrial past as a means of cultural regeneration in the region.

Heat-flow values have been obtained at six new sites in Nova Scotia and New Brunswick. These values and six previously reported for Maritime Canada range from 45 to 79 mW m−2 (1.07 to 1.89 μcal cm−2 s−1) after correction for Pleistocene glaciation. The mean 62 ± 3 mW m−2 (1.48 ± 0.06 μcal cm−2 s−1) after a glacial correction and 54 ± 3 mW m−2 (1.29 ± 0.06 μcal cm−2 s−1) without the correction are in general agreement with the average for Paleozoic orogenic belts. High heat flows in New Brunswick are probably associated with acidic or felsic volcanics with high radioactive heat production. Low heat-flow values are associated with the deep Carboniferous sedimentary basin of Prince Edward Island and northwestern Nova Scotia. Probably the region was uplifted and the surface crystalline rocks with high radioactive heat production were eroded prior to Carboniferous time. During subsequent slow subsidence, low heat production sediments were deposited in the resulting basin. High heat flows in Nova Scotia are associated with the Devonian granites and the older Meguma sediments and metasediments, which have high radioactive heat production. The heat-flow data from Nova Scotia, together with estimates of the radioactive heat production of basement rocks, are consistent with the heat-flow–heat-production relations for the eastern United States, the Canadian Shield, and for other stable areas. The temperature at the base of the crust at 35 km depth is estimated to average about 750 °C.
