What kind of figure this source publishes
The BLS category is a relative rank, not an absolute level, and it is not a first-hand measurement: it groups an occupation's percentile ranks across several published studies into four bands. It is not an employment or wage forecast, not a probability of adoption, and it does not separate automation from augmentation.
Task-level exposure

Values in this tab are predicted labels, not observations. Eloundou et al. (2023) published two rating regimes — human raters and GPT-4 — and the β shown here is derived from the GPT-4 rater basis alone; the same task can take a different value under the other regime. The unit and the meaning differ from the observed shares (%) in the other tabs, so do not place them on the same axis.

The definition, tasks and examples below are the ILO's description of that unit group, not of this occupation.
Underwater divers work under the surface of water, with or without the aid of underwater breathing apparatus, to inspect, install, repair and remove equipment and structures, conduct tests or experiments, rig explosives, photograph structures or marine life, collect various forms of aquatic life for commercial or research purposes, and find and recover missing items and persons.
Tasks
- (a) taking safety precautions, such as monitoring dive lengths and depths, and registering with authorities before diving expeditions begin;
- (b) checking and maintaining diving equipment such as helmets, masks, air tanks, diving suits, harnesses and gauges;
- (c) descending into water with the aid of diver helpers, using scuba gear or diving suits;
- (d) working under water to lay and repair bridges, piers and harbour-wall foundations;
- (e) inspecting for suspected damage and making minor repairs to ships' hulls and underwater installations;
- (f) reporting on condition of wrecked ships;
- (g) removing underwater obstructions;
- (h) drilling holes for underwater blasting;
- (i) performing various underwater tasks connected with salvage work or recovering dead bodies;
- (j) gathering shellfish, sponges and other aquatic life forms
- (j) communicating with workers on the surface while under water, using signal lines or telephones;
- (k) obtaining information about diving tasks and environmental conditions.

- construction commercial diverESCO 7541.1This occupation is broader
Commercial divers work below the surface of the water to install equipment, such as hydraulic structures, waterways and marine facilities. They also inspect, remove and repair the structures.
- harvest diverESCO 7541.2This occupation is broader
Harvest divers perform extraction and collection of marine resources, such as algae, coral, razor shells, sea urchins and sponges, in a safe, competent and responsible manner to a depth of 12 metres, using apnoea diving techniques as well as air supply equipment from the surface, open-circuit.
- rescue diverESCO 7541.3This occupation is broader
Rescue divers are divers that manage underwater emergencies. They prevent and manage problems underwater, handle dive emergencies and operate rescue equipment. Rescue divers manage diving operations in seas or waterways. They work under demanding physical conditions to rescue and retrieve people or objects.
- underwater construction supervisorESCO 3123.2Overlapping, not the same
Underwater construction supervisors monitor underwater construction projects such as tunnels, canal locks and bridge pillars. They guide and instruct construction commercial divers and make sure they adhere to safety regulations.
