The Arctic Ocean is at once a remote undersea world and a connected human landscape: its depths resist ordinary perception, its currents carry pollution from far beyond the region, and its changing waters become central to the novel’s search for the Yrr. It is also the homeland of Inuit communities whose experience of the Arctic is inseparable from displacement and cultural continuity.

Geography and the unseen ocean

The novel places the Arctic within a wider contrast between the shallow continental shelves, long familiar to human activity, and the deep ocean beyond them, an environment described as more mysterious to science than outer space. In polar waters, that difference becomes perceptual as well as geographical. Below the surface, blue water darkens toward black; without reliable visual cues or a felt sense of gravity, a diver cannot tell by sight or inner ear whether the submersible is rising or falling and must rely on its depth gauge. The ocean is not merely distant terrain: it alters the conditions by which people know where they are.

A dream experienced by Leon Anawak gives this vastness a route through particular places. He imagines climbing an iceberg formed by a glacier in Greenland, carried east by the current to the coast of Bylot Island, then freed by wind and waves and sent south. At its summit lies a meltwater lake; in the dream, the iceberg will eventually dissolve and carry him down toward the calm water and a puzzle at the source of life. The image joins the Arctic’s moving ice to the deep-sea mystery Anawak is trying to understand, while remaining explicitly a dream rather than a map of an actual descent.

Pollution and the connected food web

The Arctic’s apparent remoteness offers no protection from industrial activity elsewhere. Anawak understands that chemicals including DDT and highly toxic PCBs travel by wind and currents from Asia, North America, and Europe into the Arctic Ocean. They accumulate in the fatty tissue of whales, seals, and walruses, then pass to polar bears and people who eat them. The resulting exposure reaches Inuit communities through the food web: breast milk from Inuit women is described as containing PCB levels twenty times the amount identified as harmful by the World Health Organization, and Inuit children suffer neurological impairments.

This chain of movement gives the ocean a consequence that is both ecological and political. The damage is distributed through water, air, animals, and human bodies, while its burdens fall especially on people whose lives and food practices are rooted in the Arctic. Anawak’s reflection connects that contamination to the wider novel’s question of whether an intelligence in the deep ocean might respond to the harms humans have spread. The question is posed as a possibility, not established as the Yrr’s motive.

Homeland, relocation, and cultural continuity

For Anawak and his uncle Ijitsineq Akesuk, the Arctic is not an abstract wilderness but an inhabited homeland marked by a history of government decisions. Akesuk describes the Cold War relocation of nomadic Inuit from their traditional territory in the southern Arctic to Resolute and Grise Fjord, near the North Pole. Officials presented the move as relocation and claimed the new hunting grounds were better; Akesuk describes the result as expulsion to places distant from caribou trails and summer breeding grounds. Inuit were also moved as military radar stations were established on traditional hunting lands. He tells Anawak that he, Anawak’s parents, and others were among those relocated.

The upheaval had deeper roots. Akesuk traces hardship to the arrival of white trappers in the 1920s, the decimation of seal and caribou populations, and the move from the land into settlements amid outbreaks of polio, tuberculosis, measles, and diphtheria. By the end of the 1950s, he says, Inuit were dying from starvation and infectious disease while the government did nothing. The history makes the Arctic a site where state power, resource use, and environmental change reshape everyday survival rather than merely a distant frontier.

Akesuk also describes what followed: years of campaigning and court proceedings for compensation, in which Anawak’s father took part, and the creation of Nunavut in 1999. Political self-government could not restore the former nomadic way of life or erase the trauma. Yet traditions are being revived: people again use dog sleds, and young people learn to build igloos and light fires with flints. Akesuk also describes a changed form of mobility, in which young people roam through digital networks and tell friends in other countries about Nunavut. The account holds cultural renewal and lasting loss together, without treating either as a simple return to the past.

Deep-water change and the Yrr hypothesis

The Arctic Ocean becomes a decisive location in the scientific search for the Yrr when the cold water in the Greenland Sea stops sinking into the depths and the Gulf Stream halts. The scientists consider two possible explanations: warming water or an influx of fresh water from the Arctic that dilutes the salt-laden current until it can no longer sink. Either explanation implies intense activity at the site of the convective chimneys. Sigur Johanson concludes that the Yrr are providing an impetus for radical changes in the sea somewhere in the Arctic Ocean, not far from the vessel.

The scientists do not claim to know exactly where the Yrr live. Their possible habitats include the deepest benthic zones, abyssal plains, and deep-sea oases; Johanson argues that the investigation should focus instead on places where the Yrr must be present. This shift makes altered ocean circulation evidence of activity as well as a physical crisis. The Arctic’s water movement, ordinarily difficult to observe directly, becomes a clue that connects deep-sea life to planetary-scale change.

Narrative significance

The Arctic Ocean binds together processes that human institutions and disciplines might otherwise keep separate: circulation in the Greenland Sea, contaminants transported across continents, animals and people linked by a food web, and Indigenous histories attached to particular lands and hunting grounds. Its scale repeatedly unsettles the idea that distance means isolation. A pollutant released elsewhere can arrive in Arctic bodies; a change in deep water can alter global circulation; an ocean that seems empty from its surface can contain a form of life whose presence is inferred through its effects.

For Anawak, the region also brings scientific inquiry into contact with personal and historical belonging. The iceberg dream turns the journey toward the ocean’s depths into an image of movement, descent, and a puzzle still awaiting solution, while Akesuk’s account makes clear that the Arctic’s history cannot be reduced to a scientific field site. The ocean is both a frontier of incomplete knowledge and a lived homeland whose inhabitants have already borne the consequences of decisions made elsewhere.
