As much as Foley likes discovering shipwrecks—he's found or helped find 26 in the past 14 years—he doesn't much like spending time looking for them, at least not in the conventional ways. Rather than sending dive teams down to survey 1,000-foot transects one fin kick at a time, Foley prefers to use autonomous underwater vehicles (AUVs) to survey huge tracts of seafloor. Where the robots don't work well, Foley sends down divers armed with closed-circuit rebreathers and thrusters, allowing them to cover more ground. He wants to go faster, he says, because he needs a lot more information. Maritime archaeologists can spend years on just a few sites, but for Foley's purposes, a solitary wreck is statistically weak—nothing more than a few words from a greater conversation. To understand the entire conversation, maritime archaeologists must study many wrecks and identify patterns between them. Foley's model is not the soft science of digging and interpretation, but the hard science of high-throughput screening deployed by gene and drug researchers, who gather data at an industrial rate and analyze that data with powerful computers able to detect subtle patterns beyond the reach of ordinary analysis.
