Field Notes: Deploying the Mariana Array at 6,000 m
Eleven days, fourteen moorings and one pressure hull that did not come back the way it left. The operational record of the deepest Bathys deployment to date.
Field Operations Director. Has deployed and recovered more than 300 moorings across the Pacific and Indian Ocean basins.
Aiko Tanaka runs field operations for Bathys: vessel charters, mooring deployment, recovery and the logistics that put a sensor array where the science needs it. She started her career as a deck officer on research vessels before moving into observatory operations, and has led deployments in the Mariana, Izu-Bonin and Java trench systems.
Her Field Notes are the operational record of the Bathys array — what was deployed, what was recovered, and what the ocean did in between.
