Abstract Walrus fossils are occasionally recovered during scallop dragging in the Bay of Fundy and from sand and gravel deposits along the coastline of New Brunswick in eastern Canada. Six new fossils and four new AMS radiocarbon dates significantly increase the information concerning late-glacial to postglacial walrus in New Brunswick. Dates range from about 12 800 BP to 2 900 BP, almost half falling between 9 000 and 10 000 BP. Temporal distribution of walrus, compared to estimates of past summer sea surface temperature, suggest that in the Bay of Fundy walrus occurred in waters ranging from 12 to 15° C.

From May to October 2017 seaweeds were identified in the field and laboratory from 20 sites around Brier Island, Nova Scotia. While most sites were intertidal rocky shores, there were one small salt marsh and one eelgrass bed included in the study, and some subtidal sampling was conducted utilizing SCUBA and snorkeling. The Brier Island seaweeds comprised 152 species and varieties of which 62 were Rhodophyta, 44 were Chlorophyta, 44 were Phaeophyceae, and two species were Xanthophyceae. Three species were new records for eastern Canada: Colaconema bonne- maisoniae, C. endophyticum, and Elachista stellaris, all were pre- viously recorded from New England. The flora included eight non- native species of which Colpomenia peregrina and Bonnemaisonia hami- fera (both gametophytic and tetrasporophytic stages) were abundant at two or more sites, and the invasive Codium fragile subsp. fragile was recorded based on a single drift specimen. With 150 species and varieties of seaweeds, Brier Island has the highest species richness of a limited area of eastern Canada. The Cheney floristic index at 2.4 is higher than comparable areas, and suggests that many additional brown algae remain to be found.Keywords: Chlorophyta, Colaconema, Bay of Fundy, Brier Island, Phaeophyceae, Rhodophyta, seaweeds

Copepods and cladocerans were collected, mainly in August, from the top 0.25 m of the water column in the outer Bay of Fundy, off Brier Island, Nova Scotia (ca. 44°15′N, 66°23′W) in 1975–1978, Deer Island, New Brunswick (ca. 45°00′N, 67°00′W) in 1977–1978, and Grand Manan Island, New Brunswick (ca. 44°40′N, 66°43′W) in 1981. In 1975–1977, the dominant species at the surface off Brier Island were stage CIV-I Calanus finmarchicus and CVI-V Pseudocalanus sp. The copepods Acartia spp., Anomalocera pattersonii, Centropages sp., Eurytemora spp., and Oithonia similis and the cladocerans Evadne sp. and Podon sp. also occurred regularly. The relative abundance of Calanus finmarchicus declined during the period July–October 1976, though the proportion of stages CVI-V increased. The relative proportions of Pseudocalanus sp., and of its stages CVI-V, both declined during the same period. The community at the surface was similar to that collected in other studies from subsurface tows in the Bay of Fundy as a whole, including Brier, Deer, and Grand Manan islands. This was not true of Brier Island in 1978: CVI-V Calanus finmarchicus predominated, and other species were scarce. Our samples from Deer and Grand Manan islands resembled those from Brier Island in 1978, though CVI-V Calanus finmarchicus predominated even more strongly. We discuss the differences between our samples from Brier Island in 1978 and 1975–1977, and between the latter and our New Brunswick data. However, there is no obvious explanation for most of these anomalies.

Examination of driftwood, intertidal wood, and submerged panels from the New Brunswick coast of the Bay of Fundy yielded 34 species of marine fungi. With four exceptions, all are first reports for New Brunswick. Five are first reports for the Bay of Fundy and a further four species are first reports for Eastern Canada. Differences were observed between the species found by the various methods.

The millipede Craspedosoma raulinsii (Craspedosomatidae) is widespread in Central Europe from Belarus and southern Scandinavia west to Britain and Ireland. Although the species is often not common and rarely encountered (Blower 1985, Hoffman 1999, Lee 2006), Kime (2004) reports C. raulinsii as the third most widespread millipede in Belgium. Shelley (1990) reported C. raulinsii (as C. rawlinsii) for the first time from North America (from Gatineau Park, Quebec, Canada) and noted the occurrence is the first introduction of a representative of the order Chordeumatida in the New World. Here we report new records that suggest widespread occurrence of this introduced millipede in eastern Canada and comment on the commonly-applied spelling of the specific epithet of the species. Vouchers have been deposited in the collections of the New Brunswick Museum (NBM).

Passamaquoddy Bay

Bathymetric images of linear and circular pockmark depressions on the Bay of Fundy seafloor, offshore eastern Canada, are interpreted to have been caused by escaping gas from underlying sediment or bedrock. Shallow interstitial gas within marine sediments restricts seismic reflection imaging (acoustic masking) of sub-bottom units resulting in obscured reflections within seismic profiles, confirming that interstitial gas is present in the underlying units. Pockmark fields are frequent in several bays and shallow coastal areas along the northern coast of the Bay of Fundy. The largest field containing over 10 000 pockmarks occurs in Passamaquoddy Bay, an estuary underlain by igneous and metamorphic bedrock. These features are interpreted to be caused by generation of biogenic methane from the microbial breakdown of organic matter buried within Holocene-age sediments and along the underlying Pleistocene/Holocene unconformity. The unconformity is recorded as a distinctive horizon that represents a time when glacier recession resulted in exposure of parts of the bay to sub-aerial erosion and growth of terrestrial vegetation at locations subsequently submerged by post-glacial transgression. Three areas of potential thermogenic gas occurrence were identified in seismic profiles collected south and east of The Wolves islands, New Brunswick. The underlying bedrock has not yet been precisely mapped, although outliers of Carboniferous-age bedrock that is the major petroleum source in New Brunswick may extend into this area of the Bay of Fundy.

Cliona celata occurs in Prince Edward Island; C. lobata in Prince Edward Island and on the Gulf shore of New Brunswick; C. vastifica in the Bay of Fundy, off Sable Island, off Prince Edward Island, and off Newfoundland. Intraspecies grafts of C. celata and C. lobata succeeded, but interspecies grafts failed. This should remove doubt about the taxonomic distinctness of these two species.
