An underwater robotics specialist is using remotely operated vehicles to examine nearly 100 sites in Seattle’s Lake Union, a central urban lake in Washington state. Multiple outlets report that Phil Parisi, described as an ROV and underwater robotics expert, is working to verify and document what he refers to as “shipwreck city,” suggesting the lake contains a dense concentration of hidden maritime remnants. The effort focuses on “targets” identified in the lake and aims to confirm their nature and preserve information about the underwater history. The reporting emphasizes the scale of the investigation—nearly 100 targets—rather than specific findings at individual sites. Overall, the articles describe a systematic exploration and documentation project intended to improve understanding of what lies beneath the lake, including potential shipwrecks and other historical objects. Both sources frame the work as an exploratory verification phase, highlighting ongoing documentation rather than final conclusions.
