“…For example, Ringuette et al (2002) report that increased availability of chl in the NOW triggered the recruitment of Calanus copepod species, and the abundance of C. hyperboreus Stage CI peaked in the eastern sector in mid-May, corresponding to the peak phytoplankton bloom. Also, Karnovsky & Hunt (2002) estimated that the dominant seabird (dovekies Alle alle) in the polynya consumed ca. 5 to 14% of new phytoplankton production during spring-summer of 1998.…”

“…The North Water Polynya is host to high numbers of migrating seabirds in spring and marine mammals during winter and spring. Near Greenland, it supports an early phytoplankton bloom (Mei et al, 2002), and zooplankton are available to seabirds there in early spring (Karnovsky and Hunt, 2002;Tremblay et al, 2006aTremblay et al, , 2006b). Millions of little auks nest on the Greenland side of the North Water (Boertman and Mosbech, 1998).…”

a b s t r a c tWe compare and contrast the ecological impacts of atmospheric and oceanic circulation patterns on polar and sub-polar marine ecosystems. Circulation patterns differ strikingly between the north and south. Meridional circulation in the north provides connections between the sub-Arctic and Arctic despite the presence of encircling continental landmasses, whereas annular circulation patterns in the south tend to isolate Antarctic surface waters from those in the north. These differences influence fundamental aspects of the polar ecosystems from the amount, thickness and duration of sea ice, to the types of organisms, and the ecology of zooplankton, fish, seabirds and marine mammals. Meridional flows in both the North Pacific and the North Atlantic oceans transport heat, nutrients, and plankton northward into the Chukchi Sea, the Barents Sea, and the seas off the west coast of Greenland. In the North Atlantic, the advected heat warms the waters of the southern Barents Sea and, with advected nutrients and plankton, supports immense biomasses of fish, seabirds and marine mammals. On the Pacific side of the Arctic, cold waters flowing northward across the northern Bering and Chukchi seas during winter and spring limit the ability of boreal fish species to take advantage of high seasonal production there. Southward flow of cold Arctic waters into sub-Arctic regions of the North Atlantic occurs mainly through Fram Strait with less through the Barents Sea and the Canadian Archipelago. In the Pacific, the transport of Arctic waters and plankton southward through Bering Strait is minimal.In the Southern Ocean, the Antarctic Circumpolar Current and its associated fronts are barriers to the southward dispersal of plankton and pelagic fishes from sub-Antarctic waters, with the consequent evolution of Antarctic zooplankton and fish species largely occurring in isolation from those to the north. The Antarctic Circumpolar Current also disperses biota throughout the Southern Ocean, and as a result, the biota tends to be similar within a given broad latitudinal band. South of the Southern Boundary of the ACC, there is a large-scale divergence that brings nutrient-rich water to the surface. This divergence, along with more localized upwelling regions and deep vertical convection in winter, generates elevated nutrient levels throughout the Antarctic at the end of austral winter. However, such elevated nutrient levels do not support elevated phytoplankton productivity through the entire Southern Ocean, as iron concentrations are rapidly removed to limiting levels by spring blooms in deep waters.

“…Birds are abundant in the region, different species of ducks and geese nest on the island (Schledermann 1980), and various jaeger species, gull species, ravens, and loons are common (Godfrey 1966). In addition, the North Water Polynya is host to the largest number of seabirds known in the Arctic (Karnovsky and Hunt 2002), and marine fish are plentiful. Across Skraeling Island are the remains of settlements belonging to early PalaeoEskimo peoples and Thule Inuit (Schledermann 1990).…”

This paper presents the faunal material excavated from an Early Thule Inuit semi-subterranean house, house 15, from the Skraeling Island site (SfFk-4). In an effort to understand how the occupants of the house interacted with animals, a fine-grained zooarchaeological analysis is employed. Patterning in taxonomic and bone modification frequencies, skeletal element distributions, and prey demography are discussed. Inuit oral histories, mythology, and ethnographic sources are used to help interpret the results of the analysis and reconstruct the group’s subsistence economy.Cet article présente le matériel faunique provenant d’une habitation semi-souterraine datant du Thuléen ancien, l’habitation 15, située sur l’île Skraeling (SfFk-4). Afin de comprendre l’interaction entre les occupants de l’habitation et les animaux, une analyse détaillée des données zooarchéologiques a été produite. La répartition taxonomique, les fréquences des modifications des os, la répartition des éléments du squelette et la démographie des proies sont discutées. L’histoire orale inuit ainsi que les sources mythologiques et ethnographiques ont été utilisées pour contribuer à l’interprétation des résultats de l’analyse et pour reconstruire l’économie de subsistance du groupe
