Abnormal migration and disappearance of whales

Abnormal migration and disappearance of whales disrupts a seasonal pattern that normally makes the waters off Vancouver Island a reliable place to see migrating whales. On 12 March, Leon Anawak takes a full Zodiac out from the Blue Shark, but the passengers see no flukes or flippers. The empty water is more than a failed tourist outing: the expected animals are late or absent, and Anawak cannot account for their whereabouts.

The expected migration

The absence matters because the whales’ seasonal movements are presented in unusually concrete terms. Grey whales and humpbacks travel through British Columbia twice a year on a long round trip between wintering and feeding areas. The route described for the tour runs about sixteen thousand kilometres through the Pacific Ocean and the Bering Sea to the Chukchi Sea. In February, grey whales leave the lagoons of Baja California, while humpbacks leave the warm waters of Hawaii; both head toward Arctic summer feeding grounds. As the days shorten, they return toward Mexico, where they give birth beyond the reach of their principal predator, the orca.

For the tourists aboard the Blue Shark, the routine has commercial as well as ecological force. Davie's Whaling Station ordinarily offers a free repeat trip if a tour finds no whales. A few hours without a sighting can happen, but an entire day without one is described as seriously unusual; a whole week would be cause for concern, and had not happened before. On this outing, the group has waited more than an hour and a half, put away its cameras, and glimpsed little beyond a rocky coastline obscured by rain. Anawak has filled the wait with explanations about the region, but the familiar commentary cannot disguise the absence.

Missing animals and incomplete records

The evidence does not establish a single, complete census of the missing animals. Susan Stringer reports that a few bottlenose dolphins and sea-lions were tagged in January, but their tracking trail ends at the beginning of migration: all the tags stopped transmitting, and there has been no further signal. These records do not directly track the absent grey whales or humpbacks, so they cannot explain where those species have gone. They do, however, make the wider loss of contact harder to dismiss as merely a bad day at sea.

Stringer initially responds with reassurance, reasoning that thousands of whales cannot simply disappear and suggesting that they will turn up. Anawak answers that, evidently, they can. Her light joke about whales being stuck in traffic near Seattle briefly turns the possibility into something ordinary and local; his reply restores the unresolved seriousness of the question. Neither response supplies an explanation. The exchange instead marks a difference between the comfort of trusting a familiar migration and the unease of facing evidence that the pattern may have failed.

A disrupted ecological chain

Anawak distinguishes among the missing animals rather than treating all whales and orcas as one population. He says that the transient and offshore orcas have not appeared, while large numbers of resident orcas remain. Those residents do not favor the western side of Vancouver Island, although conditions in Johnstone Strait are becoming uncomfortable. He links that pressure to vessel traffic—ferries, cargo ships, liners, and sport-fishing boats—and to timber extraction. When forests are removed, rivers fill with silt, salmon lose spawning grounds, and resident orcas lose a food source. This is an account of strain on the resident orcas’ habitat, not a demonstrated cause of the missing grey whales and humpbacks.

The migratory whales face a separate feeding constraint. They usually reach the Vancouver area at the beginning of March after months without food. In Baja California, grey whales live on stored blubber through winter, but cannot depend on it indefinitely; they feed again after reaching these waters. Anawak rejects the suggestion that they may simply have moved farther offshore, because he believes there is not enough food there either. In Wickaninnish Bay, sandy habitat supports Onuphis elegans, a long, thin worm that grey whales eat. Such local food is part of what enables the whales to continue north toward the Arctic. The missing passage therefore puts a specific feeding place, a prey species, and the whales’ longer migration within the same concern, without proving that any one of them caused the disruption.

The scale of the concern is sharpened by the history of grey whales. In the mid-1980s, they failed to stop in the area when their numbers had been driven close to extinction by hunting. Their numbers later recovered, but the world population is still only about twenty thousand, most of whom Anawak expects to find in these waters. The present absence recalls that earlier failure of the seasonal stop while remaining distinct from it: the earlier explanation was severe depletion, whereas the current cause is not identified.

An absence that resists easy explanation

The episode places observation at the boundary of what the characters can know. Anawak watches a still ocean beneath rain and cloud, but the weather and empty horizon do not reveal whether the whales have changed course, lost their feeding grounds, or disappeared for some other reason. Elsewhere, the continental shelf is described as the comparatively familiar margin of a much less understood deep ocean; at sea, rain and cloud can erase the distinction between water and sky. These descriptions do not explain the migration anomaly. They give it a setting in which distance and limited visibility make absence difficult to interpret.

Anawak’s attention also extends beyond instruments and immediate sightings. In considering where to look for knowledge, he is directed toward Indigenous elders; the related discussion describes oral traditions disrupted by the Indian Act of 1885 and presents a teaching of interdependence: a change in a river affects people, animals, and the sea. That teaching offers an ecological frame for thinking about connected systems, not a specific traditional account of these missing whales or a solution to their disappearance. The distinction matters: the inquiry widens to include different forms of knowledge without pretending that any available source has yet identified the cause.

The whales’ absence thus remains unresolved in the supplied account. Its significance lies in the break between an expected migration and what observers can actually find, compounded by interrupted tracking and pressure on the habitats and food sources that make migration possible. The tour’s empty cameras register the visible symptom; Anawak’s worry points toward the harder question of what linked changes in the ocean may lie beyond the sightline.
