Souvenir is a collaborative project by Ohan Breiding and Shoghig Halajian that coalesces two seemingly disparate stories together—a family member's experience of surviving a tsunami while snorkeling and the longest transoceanic journey of marine organisms. It documents plastic debris that traveled from Tōhoku, Japan across the Pacific Ocean over the span of a decade and washed ashore on the Pacific Northwest coast of North America in 2022, covered with a diverse ecosystem of marine life. Presented as a video and photographic installation, Souvenir employs various image technologies—including an underwater camera, a cell phone, a drone camera—to build a visual vocabulary that can speak to the multi-scalar impacts of personal and ecological loss, and to speculate on how marine life can shed light on new strategies of survival across species and coasts.
