Audible cues and signals can get your buddy’s attention, signal a group of divers or indicate a problem you can help address. Even though we may dive to escape the noise of everyday life, we need to pay attention to the sounds around us. Doing so could make your dive even more special because your buddy got your attention to see something remarkable — or you may even save a life.
You are on the boat after a great dive when a buddy team surfaces, and one of them calls out for help. The boat crew helps get the distressed diver on board. Would you know what to do next? Whatever your level of dive training, or even if you are a nondiver dealing with an incident on land, DAN’s first aid training can help you know what to do and how to do it.
In 1995, when we first explored wunderpus territory, which overlies much of the Coral Triangle, the then-undescribed octopus’ fame had spread far and wide. The newly sensational creatures attained much of their acclaim for dancing like dandies across sandy seafloors on eight unimaginably limber arms — an eye-popping feat of acrobatic dexterity well worth traveling halfway around the world to see.
The required skills in a rescue scenario — which involved a surface swim while providing rescue breaths and removing dive gear from the victim and rescuer — were not coming easily, especially if my dive buddy was larger than me. Techniques for rescue diving seemed suited for people with a different body type and skill set — at 5 feet, 4 inches tall, I am a petite woman. Practicing rescues was challenging at best and near-impossible at worst until a course director taught me techniques and modifications that made rescuing more accessible.
Annie Crawley dan tim selamnya yang terdiri dari anak-anak dan remaja adalah beberapa penyelam yang sering mengunjungi kawasan lindung laut Edmonds Underwater Park di sebelah utara Seattle, Washington, di daerah Puget Sound, Laut Salish. Dengan pakaian selam dan kamera di tangan, para penjelajah samudra muda ini mendokumentasikan dunia bawah laut dengan Crawley sebagai mentor dan pemandu mereka. Misi mereka: menjadi suara bagi lautan.
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.
