Embolismos arteriales gaseosos en aguas poco profundas

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 20 feet (6 meters) and protection from the currents that render many urban waterways challenging to shore divers. Two experienced rescue divers with excellent buoyancy […]

Operación “Sol naciente”

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.

La vida de una babosa

Ahora bien, hay mucho más que se puede apreciar sobre estas queridas babosas de mar. En el Acuario Marítimo de Norwalk (Maritime Aquarium in Norwalk), Connecticut, los nudibranquios se han convertido en narradores de un problema al que se enfrentan nuestros océanos que es difícil de comprender pero que es fundamental conocer: el cambio climático global. El acuario ha adoptado un enfoque único para educar al público sobre esta amenaza global. Su nueva exhibición,

La inspiración de Aw

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.

EDC en Cozumel

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.

Fotografía en un entorno turbio

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.

Diving in a Time Capsule

Thunder Bay National Marine Sanctuary in Lake Huron off the northeastern coast of Michigan has nearly 100 known shipwrecks, and others are still being discovered. The oldest shipwreck there sank in 1849, but many wrecks are from the mid- and late 1800s to the early 1900s. The location, history and variety of ships — from wooden schooners to freighters — make Thunder Bay special. The wrecks are at various depths, ranging from the snorkel zone to recreational and technical diving levels.
