About
The harbour, the tide table, the lamp at the end.
Sea Marker is an independent online magazine founded in 2025 to do one thing: long-form, careful reporting on the parts of life that move too slowly to make the daily wire feeds.
Sea Marker is a quarterly of coastal reporting — lighthouses, fisheries, shipping lanes, tides, and the towns that face the water.
The magazine is run by a small editorial collective, the Sea Marker Editorial Trust, constituted as a non-profit publisher. Decisions about coverage, accuracy, and editorial direction are taken independently of any commercial interest. We do not run display advertising.
We publish under five named contributors who together edit and write the magazine. You can read about each on the contributor pages. Pieces are commissioned, reported, edited, fact-checked, and published in roughly four-week cycles.
We hold ourselves to three standards. Our editorial policy, our style guide, our ethics statement.
