Part One — The Field Projects

Three open dossiers

Everything the Society runs is kept like a field record: numbered, dated, signed, and open. These are the three dossiers currently on the station table.

PLATES II — VII
Dossier №1

FIG. 1 — The deep-water VR & AR submersible, drawn at the station. Two seats, one lagoon, every classroom invited.
Plate II. Descent trial, outer reef wall — honu escort, unscripted.

Honu XR carries a pilot, a researcher, and everyone else. Every dive is captured as live VR and AR and streamed to classrooms ashore — so the deep water off Tetiaroa is no longer a rumor, it's a field trip.

Dossier №2

The sanctuaries — turtle & lemon shark

PROTECTED WATERS

Nesting beaches on the north motu, a shark nursery in the southern lagoon — the sanctuaries are kept the way the rest of the atlas is kept: every individual logged, every return celebrated in ink.

Dossier №3

Digital Twin + Biocode — the appendix

IN SYNC · LIVE

Every observation in this atlas — every nest, sounding, sequence, and sensor ping — lands in one living model of the atoll. The Digital Twin is the page that updates itself; the Biocode is its index of life.

Part Two — Education & Kids

The Junior Naturalist's pages

Ora Hoa classes, snorkel school, and night patrols with the turtle team — Polynesian students do real science here, and these are their pages of the atlas.

PLATE VIII

STICKER SHEET №3 — “design your own submersible” studies, as voted on by the junior cohort. One of these grows up to be Honu XR.

Part Three — Provenance

Correspondence, 1967—

How a film set became a field station: one actor, twelve motu, and a promise that outlived him.

PLATE IX
TETIAROA — VIA TAHITIc. 1971

— Marlon Brando

From the founding correspondence. Brando came to Polynesia in 1960 to film Mutiny on the Bounty, bought the atoll in 1967, and held it whole. The Tetiaroa Society exists to keep his word for him.
