The seven days in the Galápagos went by too quickly, and I was ready to come back before I had even left. The Galápagos National Park and the tour operators greatly respect the destination, and conservation is their primary goal. Even with all the protections in place, the fishing industry, climate change and ocean health pressure the archipelago. Every tourist dollar that goes into the Galápagos adds persuasive emphasis that this is a place that deserves ongoing and stringent protection.
Humpback whales feed in polar waters during the summer and then migrate to tropical or subtropical waters to breed during winter. Various locations offer seasonal whale-watching, but swimming with them is legal in only a few places — Tonga is one of them. Every year its warm and sheltered waters provide a nursery for the whales, which gather there between July and October after a long migration from Antarctica.
Calling a dive is not as easy as just giving the thumbs-up signal. There are steps to follow after the signal to cancel a dive. The dive briefing should cover these procedures, and the greater the dive’s potential risk, the more attention to detail the procedures and briefing should have to make calling the dive happen as safely as possible.
Más de 100 becarios a lo largo de 20 años han participado en los programas de prácticas de DAN, trabajando con mentores establecidos en investigación, mitigación de riesgos o medicina para adquirir conocimientos y una valiosa experiencia profesional a la vez que contribuyen a las operaciones de DAN. Este año cinco becarios viajaron a Durham, Carolina del Norte, para participar en el programa.
Estás en el barco después de una gran inmersión cuando un equipo de compañeros sale a la superficie y uno de ellos pide ayuda. La tripulación del barco ayuda a subir a bordo al buceador en apuros. ¿Sabrías qué hacer a continuación? Sea cual sea tu nivel de formación en buceo, o incluso si no eres buceador y te enfrentas a un incidente en tierra, la formación en primeros auxilios de DAN puede ayudarte a saber qué hacer y cómo hacerlo.
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.
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.
Los beneficios de proteger los pastos marinos no deben subestimarse. Los pastos marinos purifican el agua, ayudan a proteger contra la erosión costera, ayudan a mantener las pesquerías de pequeña escala que sustentan comunidades y aumentan las poblaciones de peces y la biodiversidad. Absorben mucho más carbono por área que los bosques terrestres y reducen la acidificación del océano. Tener pastos marinos saludables se traduce en un océano más próspero.
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.
Los pulpos se refugian en pequeñas guaridas, son excelentes para camuflarse y están mayormente activos durante la noche, por lo que no todos los buzos han visto uno en un buceo. Pero el biólogo marino Matthew Birk, que estudia los pulpos, sintió que nunca haber visto uno en estado salvaje era una mancha en su carrera y quiso remediar la situación en un viaje a la Isla Santa Catalina cerca del sur de California.
