A glacial dispersal train of erratics derived from Paleozoic bedrock has been delineated stretching east-northeast–west-southwest across central Baffin Island. The lithologies of these erratics suggest a derivation from strata of member B of the Ordovician Ship Point Formation to the west, which are presently either submerged or covered by Quaternary sediment in the eastern part of Foxe Basin. These Paleozoic erratics were carried from Foxe Basin onto the Baffin Upland and the western edge of the Davis Highlands. They can be inferred to have reached at least Ekalugad Fiord and the eastern part of Home Bay.

Bernhard Hantzsch was a German zoologist and explorer, born in 1875, whose first work in Canada was in northernmost Labrador in 1906. He returned to the north in 1909 with the object of exploring the then unknown Foxe Basin coast of Baffin Island. His plan was to set off from Cumberland Sound and travel with Eskimos across Baffin Island by way of Nettilling Lake and the Koukdjuak River, follow the coast north and west to Fury and Hecla Strait, and then make his way to Pond Inlet. Unfortunately, the ship that was taking him to Kerketen sank in Cumberland Sound; although all aboard made their way safely to Blacklead Island, most of his supplies were lost. Nevertheless he set off, ill-equipped, in the spring of 1910 with a group of Eskimos. By the end of the year he had established winter quarters at the mouth of what is now 245 Sylvan called the Hantzsch River, with two families, Aggakdjuk, his wife Arnga and their children, and Ittusakdjuak and his wife Sirkinirk.

The addition of over 1000 earthquakes to the northern Canadian data file during the past 3 years provides sufficient data to delineate distinctive patterns of seismicity, although the short history of low level earthquake monitoring and the temporal and spatial clustering of earthquakes suggests that not all potentially active areas may yet have been identified. The data indicate areas of activity near the larger earthquakes located teleseismically prior to the post-1960 northern expansion of the Canadian Seismograph Network and additional clusters and trends that were not previously apparent. Correlations to seismicity with major deformational trends in the Yukon – Mackenzie Valley, the northern continental margin, the Arctic archipelago and encircling much of the Baffin Island – Foxe Basin area show that structures formed or reactivated by Palaeozoic and later orogenic phases are continuing activity in response to the contemporary stress field.Possible zones of Cenozoic movement show pockets of high seismic activity but important gaps in the trends remain off Banks Island, along Nares Strait, and in Davis Strait. Tectonic forces characteristic of plate margins do not appear to be acting in the Canadian Arctic, and contemporary movement of Greenland with respect to Baffin Island does not need to be invoked to explain the seismicity in the Baffin region.Epicentre clusters in the Beaufort Sea and offshore of Ellef Ringnes Island are distributed mainly over the seaward gradient of elliptically shaped free air anomalies, indicating seismic adjustment in basement structures to uncompensated wedges of Recent–Tertiary sediments. Seismicity around much of the Baffin Island – Foxe Basin block shows a significant correlation with the interval of isostatic equilibrium between broad areas of current postglacial uplift. If northeastern Baffin Island is a hinge zone in the rebound process, and the zone from Hudson Strait to northeastern Keewatin a line of inflection in the rate of uplift contours, the reactivation of structures is occurring along zones of high differential stress.

Multibeam Mapping

This study investigates the postglacial sea-level history of eastern Cumberland Peninsula, a region of Baffin Island, Nunavut where submerged terraces were documented in the 1970s. The gradient in elevation of emerged postglacial marine-limit deltas and fiord-head moraines led Dyke (1979) to propose a conceptual model for continuous postglacial submergence of the eastern peninsula. Multibeam mapping over the past decade has revealed eight unequivocal submerged deltas at 19-45 m below [present] sea level (bsl) and other relict shore-zone landforms (boulder barricade, spits, and sill platform) at 16-51 m bsl. Over a distance of 115 km from Qikiqtarjuaq to Cape Dyer, the submerged coastal features increase in depth toward the east, with a slope (0.36 m/km), somewhat less than that of the marine-limit shoreline previously documented (0.58-0.62 m/km). The submerged ice-proximal deltas, deglacial ice limits, and radiocarbon ages constrain the postglacial lowstand between 9.9 and 1.4 ka cal BP. The glacial-isostatic model ICE-7G_NA (VM7) (Peltier 2020) computes a lowstand relative sea level at 8.0 ka, the depth of which increases eastward at 0.28 m/km. The difference between observed and model-derived lowstand depths ranges from 1 m in the west to 10 m in the east and the predicted tilt is significantly less than observed (p=0.0008). The model results, emerging data on Holocene glacial re-advances on eastern Baffin Island, and evidence for proglacial delta formation point to a Cockburn (9.5-8.2 ka) age for the lowstand, most likely later in this range. This study confirms the 1970s conceptual model of postglacial submergence in outer Cumberland Peninsula and provides field evidence for further refinement of glacial-isostatic adjustment models.

Stratigraphic Position

Graptolites recovered from the organic-rich intervals, previously named the Boas River Formation in the Upper Ordovician succession on Southampton, Akpatok, and southern Baffin islands provide a reliable age assessment for the Upper Ordovician petroleum source rocks in the northern Hudson Bay, Hudson Strait, and Foxe basins. They are characterised by Anticostia lata and Anticostia hudsoni in the lower Red Head Rapids Formation on Southampton Island; Anticostia decipiens and Rectograptus socialis in the lower Foster Bay Formation on Akpatok Island; and Diplacanthograptus spiniferus and Amplexograptus praetypicalis in the lower Amadjuak Formation on southern Baffin Island. These data suggest that the organic-rich intervals in the northern Hudson Bay and Hudson Strait basins can be correlated to the Dicellograptus anceps and Paraorthograptus pacificus zones of the upper Katian, and the horizon in the Foxe Basin to the Diplacanthograptus spiniferus Zone of the lower Katian. The Boas River Formation is not deemed appropriate to use as it occurs as an organic-rich interbed in different stratigraphic units in different basins; therefore, it is suggested to abandon it as a stratigraphic term.
