Field notes
The project uses five oceanographic depth bands as an information architecture: the Sunlight zone covers 0–200 metres, while the Hadal zone reaches 6,000–11,000 metres and concerns questions for which an answer may be hard to define. Its collection spans seven named subject oceans, including Mind, Reality, Faith, and Time. The homepage also describes a four-part evidence vocabulary—known, uncertain, unknown, and possible—and offers map, search, and random-dive routes through the material.
