Dive Trip and Travel Articles

Resurfacing Stories From the Deep: Some years ago, I began assembling images for a coffee-table book on diving; until the market for such books all but disappeared. Rather than shelve the idea, I’ve revisited those journeys, reworking field notes and unpublished drafts into a digital series that captures what drew me underwater in the first place: curiosity, wonder, and respect for fragile ecosystems.
