I’ve got a short post up over at Travel + Leisure about a speculative proposal to build a “submarine hub” at San Francisco’s Aquarium of the Bay that could be used as a base for exploring local seamounts, canyons, reefs, and escarpments. The post simultaneously looks at the pioneering undersea work of Sylvia Earle, who is involved with the project, and the utopian maritime architectural projects of groups such as Ant Farm.
