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.
How nitrogen moves through coastal ecosystems — nitrate, ammonium, microbes and upwelling — and why the nitrogen cycle decides where kelp forests thrive.

From oyster-shell hatcheries to graded sheets at auction: the full nori production system — conchocelis biology, net seasons, freezing and processing.

How to toast nori over flame to revive aroma and crunch: the yaki-nori technique, gas-electric-electric hob workarounds, safety, and when to leave the sheet raw.

The pinto abalone is the small, iridescent grazer of the northeast Pacific — endangered since the 1990s and the focus of a careful hatchery recovery effort.

Northern anchovy (Engraulis mordax): the filter-feeding forage fish behind seabirds, salmon and sea lions all along the Pacific kelp coast.

Northern fur seals spend most of their lives far offshore, then crowd onto island beaches to breed. Range, deep diving, the fur trade's shadow and recovery.
Dr. Mara Ellison ·
Sandstone headlands, dolerite islands and big North Sea tides — England's northeast coast grows fine kelp forests beneath some of its oldest castles.
Tom Okafor ·
A guide to Nova Scotia's kelp beds of the North Atlantic — the species, the urchin wars, the invaders, the warming, and where to see kelp today.
Dr. Mara Ellison ·
How to design a nursery grow-out tank for kelp seedstock: flow patterns, turnover rates, lighting, aeration, materials, and scaling from bench tank to production.
Naomi Reyes ·
Rāpoka, the New Zealand sea lion, is one of the world's rarest sea lions — a subantarctic breeder slowly recolonising the mainland coast. Its biology and comeback story.
Dr. Mara Ellison ·
Rising CO₂ acidifies seawater — but it also fertilises algae. What ocean acidification really does to kelp growth, urchins and whole reef food webs.
Dr. Theo Nakamura ·
Ocean alkalinity enhancement removes CO2 by shifting seawater chemistry. Here is the drawdown chain, dose-by-dose: how much carbon, how fast, and where.
Dr. Lena Fischer ·
Ocean alkalinity enhancement removes carbon without planting anything. How is that measured? The chemistry, models and sensors behind OAE's proof problem.
Priya Raman ·
The biological carbon pump moves billions of tonnes of carbon from the sunlit surface into the deep ocean every year. Here's how the living conveyor works.
Priya Raman ·
No single body governs ocean carbon removal. From the London Protocol to national permits, here is the patchwork of rules taking shape — and the gaps.
Priya Raman ·
Why the sea turns green, turquoise or milky — and how ocean-colour satellites read chlorophyll from orbit to map blooms, currents and ocean life.
Dr. Mara Ellison ·
A full career guide to ocean science communication — writing, film, campaigns and interpretation — with pay realities, entry routes and a twelve-month plan.
Tom Okafor ·
How carbon registries issue, serialise, track and retire blue carbon credits — and what buyers should check before trusting a listing.
Priya Raman ·
A field guide to remote sensing and geospatial careers in ocean science: the daily work, a portfolio that gets interviews, and where the jobs hide.
Priya Raman ·
The ocean is losing oxygen — measurably and globally. How warming and nutrient stress squeeze marine life's air supply, and what that does to kelp forests.
Dr. Lena Fischer ·
Ocean engineering spans naval architecture, robotics, coastal and offshore work. A guide to the disciplines, degrees, tools and sectors hiring now.
Naomi Reyes ·
Ocean fronts — the sharp boundaries where different water masses collide — concentrate plankton, baitfish and predators into living lines. Here's why they matter.
Dr. Lena Fischer ·
Ocean gliders ride buoyancy, not propellers, for months at sea. How these slow torpedo-shaped robots survey storms, currents and kelp coasts on sips of power.
Dr. Mara Ellison ·
Five vast gyres turn like slow wheels in every ocean basin, shaping currents, climate and where plastic gathers. Here's how ocean gyres actually work.
