If you like the idea of a liveaboard adventure with remote, open-ocean diving where your dive boat is likely the only one on the reef, you’ll love a trip to Flower Garden Banks. It remains one of the best-kept secrets for wilderness diving in the continental U.S., where you can expect rare encounters such as a longlure frogfish on a sponge, scalloped hammerhead sharks feeding or a whale shark swimming by.
Ubicada en las Islas de la Bahía de Honduras, Roatán es una joya tropical situada en las aguas turquesas del mar Caribe. La más grande de las Islas de la Bahía, Roatán, se encuentra a aproximadamente 48 km (30 millas) de la costa de Honduras, entre Útila y Guanaja. Su sistema arrecifal periférico conforma el borde más austral del Arrecife Mesoamericano (el segundo sistema arrecifal más grande del mundo) y es probablemente la principal atracción de Roatán.
A diver didn’t heed the divemaster’s warning and was lost at sea. Deploying his large surface marker buoy helped with his rescue. DAN recommends that divers always listen to the dive briefing and follow all directions and always carry an SMB and reel. If your breathing-gas supply is critically low, get to the surface at a safe ascent rate, and then monitor for signs of decompression illness. It is better to deal with DCI on the surface than to run out of breathing gas at depth.
In Fall 2013, my wife, Liv, and I were supervising 16 new divers who were experiencing low visibility for the first time. Our training site had a maximum depth of […]
La historia de la búsqueda del submarino japonés I-52 es uno de dos descubrimientos separados por el tiempo y el propósito. En 1944, en la oscuridad de la noche en el océano Atlántico, un grupo de buques antisubmarinos de la Marina de los Estados Unidos estaba en busca de una reunión clandestina entre tripulaciones navales alemanas y japonesas. Sobre la base de la información obtenida por los servicios de inteligencia, pretendían sorprender y hundir los dos submarinos que supuestamente intercambiarían información militar. Medio siglo más tarde, el I-52 aún yacía sobre el lecho marino sin haber sido descubierto, pero esta vez la búsqueda era en la oscuridad de la profundidad del océano en busca de una posibilidad, no destrucción.
Michael Aw’s early life while growing up in Singapore — he didn’t see the ocean until age 17 — gave few clues that he would one day become one of the most influential print journalists in destination diving and ocean conservation. The author of or major contributor to 43 books, Aw created Ocean Geographic magazine in 2007 and also leads expeditions, often to exotic regions. He now hopes to raise awareness of the folly of shark-finning and the overexploitation of our marine resources.
Our checkout dive was easy, with a maximum depth of 75 feet for 50 minutes. The current was slight, and the visibility was spectacular — an ideal first dive. It closed with a nice, slow ascent and a three-minute safety stop. When we returned to the boat, I felt a sudden tingling in my right foot followed by a dull ache in my knee. I assumed the worst, thinking I had decompression sickness (DCS). When I reviewed the dive in my mind, however, that seemed impossible.
Turbid water can be a challenging environment for underwater photographers, particularly when shooting wide angle. Turbid water may not appear brown or green from the surface — in many cases the water looks entirely different once we drop in and begin the dive. All water is turbid to some degree. Understanding what causes turbidity and knowing how to work around it can make a world of difference when shooting in those conditions. One of the best skills a photographer can develop, particularly for shooting wide angle, is learning how to read water quality.
A veces la vida se complica —por obligaciones familiares, lesiones imprevistas, responsabilidades laborales o eventos sociales— o quizás el mundo que conocemos deja de funcionar por un tiempo. Cuando estas cosas nos abruman, muchas personas tienden a sacrificar el ejercicio primero. Es posible que se pierda algunos entrenamientos y luego su rutina de ejercicios lentamente pasa de ser regular a inexistente. Esto le sucede a la mayoría de las personas —incluso a expertos en aptitud física y atletas profesionales— en algún momento de sus vidas. Si bien puede ser un desafío, reanudar su rutina de ejercicios es posible.
Interactions between different species, whether above or below water, typically revolve around confrontations between predators and prey. At the opposite and more harmonious end of the spectrum, a scattering of unrelated species coevolved to form lifelong alliances for their mutual security. These relatively rare go-along-to-get-along partnerships provide a net benefit for both parties, improving each species’ reproductive success. The close living arrangement between weak-eyed alpheid snapping shrimp and sharp-eyed partner gobies is a classic example of symbiosis in the sea.
