Read the following passage carefully:
Before Captain Tobias Finch successfully hoisted the bronze astrolabe from the wrecked merchant vessel The Wanderer in the autumn of 2019, his marine survey team spent six months mapping the seabed using side-scan sonar. However, the true breakthrough had occurred three years prior to that sonar survey, when archival researcher Clara Higgins uncovered a forgotten 1682 ship's log in a maritime museum detailing the reef's location. Following the 2019 extraction of the astrolabe, Finch’s team spent two years conserving the metal in a specialized chemical bath before finally displaying the artifact at the International Maritime Summit in 2022. Remarkably, preliminary timber sampling of the hull—conducted immediately after the sonar mapping was completed but prior to the astrolabe's extraction—had already confirmed the vessel’s identity.
