Exploring Attu’s Underwater Battlefield and Offshore Environment

Features

Expedition features provide reflections on experiences, science, technology, and other elements of Exploring Attu’s Underwater Battlefield and Offshore Environment.

The maritime history of Atux̂ (indigenous endonym for Attu) is not limited to World War II, as 3,000 years before the battle, ancestral Sasignan, likely from the Rat Islands to the east, came to the island via boats. They brought with them a several thousand year history of maritime focus and knowledge of seascapes that shaped individual and community identities for all Unangax̂ (indigenous endonym for Aleut) past and present in the Aleutian Islands.

In the offshore environment of the Aleutian Islands, where there can often be a paucity of hard bottom substrate for settling larvae, shipwrecks often become areas of high biological diversity. The artificial substrate these shipwrecks provide can be home to many species of fish and mobile fauna, but also to deep-sea or cold-water corals.

The destructive images of shipwrecks and the nearly frozen-in-time Massacre Bay seafloor bring a physical realness to Attu’s wartime past that may help bring awareness to this oft-forgotten chapter of history.

This project seeks to bring attention to the World War II Battle of Attu (1943) through ocean research and exploration. Surveys of the seafloor will be executed using synthetic aperture sonar (SAS), an emergent form of marine remote sensing technology.
