During the Windows to the Deep 2019 expedition, we had identified several sonar anomalies to further explore as potential shipwreck sites. Finding wrecks on the seafloor is akin to searching for a needle in a haystack – historical research as to where, when, and why a ship may have sunk helps us to better target the search area and then follow-up seafloor mapping allows us to further pinpoint potential targets…but it isn’t until we can visually survey a site that we can know for sure if we’ve found something of archaeological significance.
