It’s been more than a year since many divers have traveled internationally and visited beloved or new dive destinations. Although it is unclear when and which international destinations will be fully accessible, it’s important to stay proactive about important travel documentation preparation.
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.
Manfaat melindungi lamun tidak dapat dilebih-lebihkan. Lamun memurnikan air, membantu melindungi dari erosi pantai, membantu mempertahankan perikanan skala kecil yang mendukung masyarakat, serta meningkatkan populasi ikan dan keanekaragaman hayati. Lamun menyerap lebih banyak karbon per area daripada hutan darat dan mengurangi pengasaman laut. Lamun yang sehat berarti laut yang lebih sehat.
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. Perhaps it’s my naturally rebellious side.”
Known for their striking colors, patterns and forms, nudibranchs are found in seas all over the world. Sculptor Gar Waterman’s fascination with these sea slugs extends beyond his aesthetic appreciation for their unique, organic form. Because most nudibranchs have a life span of less than a year and adapt rapidly to changes in their environment, they help scientists understand the impact of global warming on ocean health. With each nudibranch that he has cut, chiseled and polished from stone, Waterman hopes to communicate their quirky beauty and scientific role.
My buddy and I ascended to 20 feet for our safety stop. As soon as we surfaced I thought I saw the boat moving away from me but quickly realized I was disoriented. It felt like vertigo, but I managed to get on board the boat. I removed my gear and was talking to my buddy when I started involuntarily leaning forward until I lost my balance and collapsed face-down on the deck. I felt paralyzed and couldn’t get up.
