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.
Mangroves, salt marshes, seagrasses and kelp all store coastal carbon — differently. An honest comparison of stocks, rates, permanence, MRV readiness and co-benefits.

Dulse is the red seaweed the North Atlantic has snacked on for a thousand years — protein-rich, bacon-savoury when fried, and stranger in its life cycle than you think.

Marine heatwaves are now a farm-planning reality. Triggers to watch, decision trees for warm years, and the seedstock and layout choices that hedge the heat.
Naomi Reyes ·
A production guide to fermenting seaweed commercially — microbes, brines, food-safety controls, and how fermentation turns a glut into a shelf-stable product.

Fish-eating anemone (Urticina piscivora) species profile: the big red anemone that catches fish under the kelp canopy and doubles as sea star prey.
Dr. Mara Ellison ·
Five-ribbed kelp (Costaria costata) is the wide, ripple-edged kelp of northeast Pacific reefs — biology, kitchen uses and how it differs from wakame.
Dr. Mara Ellison ·
A guide to the Gaspé Peninsula's kelp coast: cold green water, capelin runs on the beaches, the gannet cliffs of Percé, and the kelp forests of the St Lawrence.
Dr. Lena Fischer ·
Kelp bass — calico bass to the anglers who love them — are the signature sportfish of the kelp canopy. Biology, slow growth, sex change and sustainable fishing.
Dr. Mara Ellison ·
What carbon leakage is, how activity-shifting and market leakage affect kelp and blue carbon projects, and how credible accounting deals with it.
Priya Raman ·
Abalone are kelp-eaters by nature. How farms grow their own feed kelp, what fresh kelp does to growth and shell colour, and how to design an integrated abalone-kelp system.
Naomi Reyes ·
Kelp has no roots, yet builds the fastest-growing forests on Earth. How nitrogen, phosphorus and trace metals reach kelp blades — and how kelp recycles them back.
Dr. Theo Nakamura ·
Soft as jelly, clinging like a limpet: the kelp snailfish lives where the forest meets the rock. Identification, ecology and where to look for one.

How do you tell a real marine climate commitment from greenwash? A plain-language framework for reading net-zero ocean claims — and the questions that expose the gaps.
