Researchers exploring the maritime archaeology of Attu, the most western part of the Aleutian Islands, where the Battle of Attu took place in 1943, used Groton-based ThayerMahan's advanced sonar imagery equipment to find two shipwrecks: the Japanese Kotohira Maru and the SS Dellwood of the United States.
 

ThayerMahan's technology provided underwater imagery of the waters around Attu, as what existed before were hand-drawn maps and lead line surveys from the 1940s, said Alexander Campbell, a hydrographer and survey technician who traveled to Alaska to work on the project.

This created a “snapshot” of the wrecks from the 1940s, said Connor Link, a hydrographer and survey technician who also traveled to Alaska.
