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.
Suspended sediment has quietly shrunk some of the world's kelp forests. How turbidity works, how sedimentation smothers recruits, and how clarity returns.

Turf-forming algae are the low, weedy mats that move in when kelp forests fall — and can hold a reef in place. A group profile of the kelp forest's most stubborn rival.

The mesopelagic twilight zone holds more fish than any other habitat on Earth and quietly moves carbon to the deep sea. Here's what lives there — and why it matters.

Octopus bimaculoides is a small den-dwelling octopus of California's rocky kelp reefs, named for the blue-ringed ocelli behind its eyes. Habits and habitat.

Ulva grows faster than almost any farmed seaweed and cleans up nutrient pollution — but it sporulates, frays and defies handling. A practical farming guide.

Every blue carbon number carries error bars. Here is how uncertainty is measured, discounted and buffered — and how to read a carbon account like an analyst.

Underwater, sound is the only sense that travels. How sound speed works in seawater, what the SOFAR channel is, and why the ocean is far noisier than it seems.

Underwater photo gear without the hype: how housings, ports, domes, strobes and trays actually work, what to buy first, and how to keep salt water out.

Kelp forests make navigation both easier (vertical landmarks) and harder (featureless canopy walls). Learn compass discipline plus natural navigation by light and surge.

Careers in underwater robotics: the engineers and technicians who build, wire, waterproof and field-repair AUVs, ROVs and gliders — and how to get in.

A pencil, a slate and a slow drift through the canopy: how underwater sketching turns an ordinary kelp dive into serious observation practice.

Kelp forests eat daylight. How to choose a primary torch and backup light for kelp diving, read lumens honestly, and use light without harassing wildlife.

Where wind-driven upwelling stalls behind headlands, pockets of warm, retentive water form. These 'upwelling shadows' shape larvae, kelp and climate refuges.

How to make vegetarian dashi from kombu and dried shiitake: cold-brew and hot methods, the glutamate-guanylate synergy, and what to cook with it.

Necora puber — red eyes, velvety shell, paddle legs and a famous temper — is the reef's feistiest crab from Norway to Iberia, and a quiet kelp-forest worker.

What happens when a third-party auditor arrives at a blue carbon project — the documents, the field visits, the math checks and the verdicts.

The vermilion rockfish is a deep-bodied red rockfish of the mid-water reef zone. Identification, biology, barotrauma and the fishery story.

The voluntary carbon market turns verified emissions cuts into tradable credits. How it is governed, what went wrong, and where ocean carbon fits.
Priya Raman ·
Voluntary and compliance carbon markets run on different rules, prices and claims. Where blue carbon credits fit today, and where the boundary is moving.

Wakame, kombu and nori do three different jobs in the kitchen. Flavour, texture, buying forms, substitutions and storage, side by side.
