In her work, Rachel Lance, Ph.D., focuses on extreme environments, particularly the effects of explosions. “The human body is fascinating, especially when it fails,” she says. “We are not naturally equipped to survive in a deep underwater environment, so I am fascinated with the idea of finding ways to do so anyway.

Fotogrametri adalah proses mengumpulkan serangkaian gambar diam atau video dari suatu objek, seperti kapal karam, dan kemudian memasukkan gambar-gambar tersebut ke dalam perangkat lunak yang dapat melakukan triangulasi pada titik-titik yang difoto untuk membuat model 3D. Banyak aplikasi dunia nyata yang dapat menggunakan teknologi ini, termasuk arsitektur, teknik, forensik, arkeologi, pemetaan, dan permainan video. Becky Kagan Schott senang melihat bangkai kapal menjadi hidup dengan cara yang tidak akan pernah bisa dilakukan oleh sebuah foto.
