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.
Dried seaweed expands five to ten times and each species wants a different soak. Times, water ratios and the mistakes that turn wakame slimy — one guide.

Three crews keep an oceanographic ship alive — deck, engine and science. Here's what each actually does, the tickets to get aboard, and the life at sea.

The rhinoceros auklet: the puffin's burrowing cousin with a bill 'horn', night-time colony returns, and fish-laden commutes over kelp-rich shelf water.

Rhode Island's kelp beds were already at their warm limit when the water started heating. What remains — and what was lost — is a preview of New England's future.

Long brown streamers on the surf-struck low shore: how to identify ribbon kelp, follow its fierce seasonal cycle, and place it among its edible kin.

Rip currents are the surf zone's return plumbing — narrow, fast rivers of seawater leaving the beach. The physics behind them, and how to get out of one.
Dr. Lena Fischer ·
Rivers deliver iron, silica and nutrients that kelp need — and sediment, freshets and effluent that can bury them. How land–sea connectivity shapes kelp forests.
Dr. Lena Fischer ·
River plumes deliver nutrients that feed kelp forests — and floods that smother them in sediment and fresh water. The double-edged physics of the river mouth.

Why rocky reefs flip from kelp forest to urchin barren — and why flipping them back is so much harder. Alternate stable states and hysteresis, explained.

Some reefs are too deep, too cold or too dangerous for divers. Remotely operated vehicles take the instruments instead. How ROVs changed reef science.

Meet the saddleback gunnel — the saddle-marked, eel-shaped shore fish of Pacific kelp edges, and how to tell it from true eels and its gunnel relatives.

Sado Island in the Sea of Japan pairs warm-temperate kelp reefs with centuries of tub-boat fishing, rice-terraced hills and a storied gold-mining past.

Pollachius virens grows up inside the kelp and hunts beyond it — the dark gadoid whose juveniles fill northeast Atlantic kelp forests every autumn.
