The domain

You cannot download the ocean.

Below the waterline: no GPS, no radio, no light. The water column cannot be scraped or sensed from orbit. Cables, ports, wind farms and reservoirs are monitored blind, with years between inspections. The data must be collected in the water, by something that lives there.

The loop

Dive. Survey. Surface. Sync.

1

Dive

Silent ballast pulls it under. No thruster noise, no wake, no splash.

2

Survey

Camera and sonar transects along cables, foundations and walls.

3

Surface

Pops up positively buoyant and grabs a fresh GPS fix.

4

Sync

Position, health and alerts go out. New waypoints come in. It dives again.

No tether. No boat. No pilot. If anything fails, it surfaces by physics, not by code.

The namesake

Pottwal [ˈpɔtval]

German for sperm whale: the deepest-diving predator on Earth. It hunts in total darkness, by sonar.

2 000 M

Routine hunting depth. Two hundred times the pressure at the surface.

230 dB

The loudest biological signal on Earth. Its clicks carry for kilometres.

90 MIN

Underwater on a single breath, dive after dive, around the clock.

Astronomy calls them telescopes.
We call ours whales.
