Time For More Research
Even if they know where the Noonday Rock is, the people from the NOAA knew that there was still a lot of work to do. They continued to do more sonar scans of the area and found a structure that looks like a shipwreck. It just so happens that it was close to the Noonday Rock.
They deployed another ROV to search the area, and many were optimistic that they would find the significant shipwreck right away. Unfortunately, things didn’t go as planned, and it looks like they learned that great discoveries might take more time.
