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.
Diving and snorkelling where seals and sea lions live: keeping legal distances, reading their body language, what to do when one approaches — and why the animal decides.

Kelp forests, seagrass meadows and estuaries trade food, animals and larvae across the coastal mosaic. Why connectivity — not patch size — decides resilience.
Dr. Mara Ellison ·
Seasickness ruins more ocean days than weather does. The prevention playbook that genuinely works: positioning, horizon, medication timing, food and habits.
Tom Okafor ·
Why the sea is salty, why it's slightly alkaline, and why its pH is drifting. A gentle but rigorous introduction to the chemistry that rules marine life.
Dr. Lena Fischer ·
Seaweed belongs in the bread oven: it seasons dough from within. Recipes and ratios for kelp focaccia, nori crackers, dulse rolls and soda bread.
Sofia Andersson ·
An honest look at making biochar from seaweed — how pyrolysis handles wet, salty biomass, what the ash and salt do to soils, and where the carbon case holds up.
Priya Raman ·
The real production chain behind seaweed packaging — alginate extraction, film casting, the coatings that beat plastic, and the honest limits on scale and strength.
Naomi Reyes ·
A seaweed biorefinery cascades one harvest into several products — pigments, alginate, feed, biochar. How the fractionation order works, and the trade-offs.
Naomi Reyes ·
How kelp becomes a farm biostimulant: extraction choices, quality control, the regulatory rules in major markets, and what the field evidence actually supports.
Naomi Reyes ·
Nori eggs, miso soup, seaweed butter toast and more — seven practical, delicious ways to put seaweed on your breakfast table every week.
Sofia Andersson ·
Who is allowed to count seaweed carbon, under which rules? Mapping the standards landscape from the IPCC to registries to corporate inventories.
Priya Raman ·
How a lifecycle assessment of farmed seaweed actually works — functional units, system boundaries, allocation and the pitfalls that produce misleading footprints.
Priya Raman ·
How to build and verify a kelp cold chain: landing station design, chilling tech from slurry ice to blast chillers, handling rules and HACCP temperature validation.
Naomi Reyes ·
Green, brown or red: seaweed colour is chemistry plus ancestry. A guide to algal pigments, the three seaweed lineages, and what colour says about depth.
Dr. Theo Nakamura ·
Kelp fights back without moving. How phlorotannins, iodine bursts and acid vacuoles deter grazers and foulers — and why that chemistry shapes whole reefs.
Dr. Theo Nakamura ·
Kelp disease moves faster than most farm visits. How to build a farm-level surveillance protocol — baseline, triggers, sampling cadence — that catches trouble early.
Dr. Mara Ellison ·
Offtake contracts, pricing structures, quality specs and red flags — a practical guide for seaweed farms negotiating with buyers, from farm gate to signature.
Naomi Reyes ·
Consent gets the lines in; relations keep them there. The ongoing craft of being a good harbour neighbour: incidents, viewscape, shared gear, schools and winter check-ins.
Naomi Reyes ·
How seaweed farm cooperatives work — shared hatcheries, boats and marketing — the models that succeed, the governance that holds, and how to set one up.
Jack Callum ·
How small seaweed farms actually get funded: grants, loans, equity and pre-sales — plus what lenders ask before they say yes, and the mistakes that sink applications.
Naomi Reyes ·
Seaweed farm insurance explained: what aquaculture policies actually cover, where the gaps bite, and how to cut your premium by cutting your true risk.
Naomi Reyes ·
How seaweed farm licensing differs across the world's kelp-growing coasts — four permitting architectures, what each means for growers, and how to choose.

Working a kelp farm means cold water, lines under tension and small crews. The complete safety framework: PPE, man-overboard drills, weather limits and lift plans.
Naomi Reyes ·
A working-day guide to seaweed farm safety: the hazards that actually hurt people, vessel and line protocols, cold-water rules and the checklists crews should run every trip.
