Whale tracking tag

The Whale tracking tag is a device for gathering information from a whale that cannot safely or reliably be observed at close range. In Leon Anawak’s investigation, it becomes a practical answer to a pressing uncertainty: the whales remain in the grip of whatever has affected them, and researchers need to learn what they are doing. The eventual record from Lucy shows the tag’s value most clearly when its measurements are combined with video and the tracking capabilities of the URA underwater robot.

Purpose and practical constraints

Anawak considers tagging a whale while lying awake in his Vancouver apartment. The idea is to fit one of the rampaging animals with a transmitter and a camera, allowing its movements to provide answers that observation from a boat cannot. Yet the plan immediately encounters the animal’s physical independence: even calm whales seldom remain still, and a whale behaving aggressively would be harder still to approach. Anawak also recognizes that the skin itself presents a problem for attachment.

Existing methods offer no easy solution. Scientists have used suction cups to attach tags and time-depth recorders, sometimes placing them with a long pole from a boat. Such cups, however, hold against the force of the water for only a few hours. Another approach bolts a tag to the dorsal fin, but that still requires someone to get close to the whale. The issue is therefore not simply how to collect data; it is how to keep an instrument attached long enough to be useful without making the attempt dangerously dependent on proximity.

Anawak considers whether the whale could be stunned, then rejects the option as too complicated. A tag by itself would also be insufficient. The investigation needs both satellite telemetry and pictures, so the proposed observation system joins location data to visual evidence. Anawak’s next thought is that the attachment method will require a good marksman. He then searches for information about a technique he has read about and finds the Underwater Robotics and Application Laboratory in Tokyo. The passage establishes his search for a workable method, but does not describe the precise procedure used to attach the tag.

From tag to combined observation

The later tracking of Lucy demonstrates why the tag is only one part of the system. John Ford monitors the URA’s footage of Lucy and a pod of grey whales on one screen, while another displays their positions in a three-dimensional grid. The robot identifies Lucy by matching the pattern of her tail flukes to the sounds she makes. Once it has identified her, her position appears on the grid; even a dive into the darkest depths would not cause the robot to lose track of her.

Alongside this acoustic and visual tracking, data continue to arrive from the tag embedded in Lucy’s blubber. The tag supplies her heart rate, dive depth, position, temperature, pressure, and light readings. The different streams of evidence answer different questions: the URA follows and records the whale, while the tag reports conditions associated with her body and dives. Together they produce a detailed account of Lucy’s activity rather than an isolated sighting or a location plotted on a map.

Lucy’s twenty-four-hour record

The combined observations provide a picture of what Lucy has been doing over a full twenty-four hours. The duration matters because her behavior is not represented as a single dramatic moment: changes in position and formation can be followed alongside the tag’s successive readings. In the control room, Ford and two assistants monitor the information through the night; illness has reduced the observation team from four people to three. The sustained, demanding work of watching the output is part of how the instrument’s raw measurements become usable evidence.

That evidence also changes the scale of the inquiry. Anawak’s original proposal responds to the difficulty of approaching a whale and the insufficiency of seeing only what happens at the surface. Lucy’s tagged movements and the URA’s ability to follow her make it possible to assemble a much more continuous record of an animal’s behavior. The resulting account is explicitly framed as a day in the life of a rampaging whale, placing the abnormal behavior within a measured sequence rather than leaving it as a frightening, unexplained encounter.

Significance and limits

The tag’s importance rests on cooperation between animal-borne measurement and external observation. Its readings alone would not show everything Lucy did; the URA’s footage and tracking alone would not supply the tag’s physiological and environmental measurements. By bringing the two together, the researchers can compare where Lucy is, how deeply she dives, and what the tag registers during her movements. The resulting evidence is richer than either instrument could provide on its own.

At the same time, the account keeps the technology’s practical limits in view. Suction-mounted instruments may remain attached for only hours, and any method that requires approaching a whale risks failure before the data can be collected. The system does not make the whales predictable or explain the force behind their aggression by itself. Rather, the Whale tracking tag helps turn an elusive, dangerous animal into an observable subject over time—one whose actions can be followed closely enough to support the wider investigation.
