The Tidewright Journal
Encyclopedia entries, coastal atlas guides, science explainers, farming know-how and recipes — written by Tidewright’s scientists, engineers, chefs and field crews, and open to everyone.
Discurria insessa, the kelp limpet, lives its whole life on a single stipe of feather boa kelp — one of the coast's strictest partnerships.

Every kelp blade carries a living film of microbes that shapes its growth, defence and disease. Inside the kelp microbiome — and what warming does to it.

After dark the kelp forest changes shifts — octopus hunt, lobsters walk, plankton glows. How to night-snorkel kelp beds safely: torches, exits, buddies and limits.

The blue economy needs engineers as much as biologists — AUVs, satellites, eDNA and ocean data. A map of ocean-tech careers and how to enter them.

Meet the ochre sea star, the purple tidepool predator whose removal in a famous 1960s experiment coined the keystone species concept.
Dr. Theo Nakamura ·
Porichthys notatus hums for hours to woo mates, glows with borrowed light and survives hours out of water. Meet the kelp coast's oddest neighbour.

Langebaan Lagoon runs warm and shallow while the Atlantic outside stays cold and kelp-lined. A guide to South Africa's surprising West Coast shores.

Before Tidewright's second Lofoten winter, the crew trained for sea ice, four-hour twilight and frozen shackles. Field notes from the course we built.

DNA barcoding reads a short, standard gene to name a seaweed. How it works, what it has revealed about kelp's cryptic species — and where it struggles.

From umami-rich kombu water to kelp tea and seaweed-washed spirits, here's how to drink the sea responsibly — infusions, temperature rules and three cocktails.
Sofia Andersson ·
A working guide to hazard analysis and critical control points for seaweed farms and small processors — the real hazards, the paperwork, and audit day.
Naomi Reyes ·
A guide to the Sulu Archipelago's seaweed coast — eucheumatoid farms, village economies, ice-ice disease, and how reef and farm share the shallows.

Master sunomono, Japan's vinegared seaweed salad: the awase-zu dressing formula, properly salted cucumber, silky wakame and five smart variations.

Urchin barrens can persist for decades even when kelp conditions return. Why barrens behave as an alternative stable state — and how reefs flip back.

Why Tidewright crews seed Holdfast lines at forty degrees to the prevailing swell — the fieldcraft, physics and early failures behind a deceptively simple rule.

Winged kelp (alaria) is the Atlantic answer to wakame — silky, mild and quick to cook. A prep guide, three recipes and sourcing advice for this cold-water kelp.

Meet the bay pipefish, the Pacific coast's eelgrass mimic — a seahorse relative that hunts like a drifting grass blade from Alaska to Baja.
Dr. Theo Nakamura ·
A September swell off Hokkaido took one Holdfast line whole. What losing Line Seven taught us about anchors, graceful failure and honest reporting.
Jack Callum ·
A Coastal Atlas guide to Hokkaido: Rishiri, Rausu and Hidaka kombu beds, the beach-drying harvest culture, and the kelp road that fed Kyoto for centuries.
Dr. Theo Nakamura ·
Every kelp species has a temperature window. Learn the physiology of heat stress, why gametophytes are weakest, and how scientists measure and breed thermal tolerance.
Dr. Lena Fischer ·
How nori farming actually works — the shell-grown conchocelis stage, net seeding, the winter crop cycle and the repeated harvests that built an industry.
Naomi Reyes ·
Winter is when a seaweed farm earns its keep: crop checks between gales, fouling pulses, gear inspections and the growth surge fed by cold, rich water.

Make seaweed pasta three ways: a kelp-flour dough that stays tender, a dulse-butter pan sauce, and a crisped-nori topping. Ratios, technique, timing.
