Basking Shark vs. Whale Shark

Whale sharks are easy. Basking sharks are hard. Whale sharks usually inhabit warm, tropical waters, while baskers prefer cooler, temperate regions.

En busca del éxito como buceadora profesional

Young women beginning their careers as dive instructors regularly ask me how to be heard on a dive boat. Their experience is that guests don’t naturally listen to their directions. The dive industry has improved, and I don’t want to downplay the vast improvements that have already happened for women dive professionals. But this is a common question, so it remains relevant.

Vaya donde nadie ha ido antes

To pee or not to pee? That is not the question for technical divers, instructors, or others who spend long hours in the water. Proper hydration and comfort ensure that urine will flow. The question is, What’s the best way to handle it?

Fighting the European Green Crab Invasion 

One of the world’s most destructive invasive species is gaining new ground — or water — in Canada and up to Alaska. Carcinus maenas, which translates to “raving mad crab,” outcompetes many local crab species in devouring clams, oysters, and mussels, and they sometimes even eat other crabs and juvenile fish. They destroy seagrass, an essential habitat for juvenile salmon, herring, rockfish, and many other marine animals.

Le damos la bienvenida a la luz que se filtra desde la superficie

Imagine waking up in the early hours of the morning at your favorite dive site. The sun hasn’t quite peaked above the horizon, and light is minimal. You don your dive gear, grab your camera, and giant stride off the back of the boat to begin your descent into the dimly lit ocean.

Gerald Nowak: entornos extremos

Over the years I have often admired Gerald Nowak’s underwater photos. There is so little overlap between the markets available to European versus North American photographers, however, that I did not know the backstory of his career. A recent phone call rectified that.

Bucear después de un derrame ocular

P: Recientemente tuve un derrame ocular. ¿Podré seguir buceando una vez que se haya resuelto? R: Las principales preocupaciones con un derrame ocular (oclusión de la arteria central de la retina, o CRAO, por sus siglas en inglés) son la causa subyacente y los medicamentos que el médico le indique para su tratamiento. Antes de volver a bucear, converse con su oftalmólogo o médico para determinar la causa de origen del derrame ocular inicial, la probabilidad de que vuelva a ocurrir y su salud cardiovascular en general.

Aprendizaje a partir del incidente del Conception

On Sept. 2, 2019, the small passenger vessel Conception burned to the waterline off Santa Cruz Island, California, killing 34 people. This wasn’t the first liveaboard fire, but the fearful reactions to this deadly tragedy echoed throughout the scuba industry. Liveaboard fires that have occurred since this incident have further fueled industry concerns.

A safety drill, including what to do in case of fire or abandoning ship, should occur at the beginning of every cruise.

En un intento de rescate la capacitación es fundamental

Muchos buzos se enorgullecen de estar cómodos en el agua y a veces desafían sus límites respecto al consumo de aire, superan su tiempo de fondo o aprovechan una última oportunidad de capturar a un gran pez con una cámara o un arpón antes de ascender. Algunos de ellos desarrollan reputaciones en la comunidad de buceo por ser buzos competentes al verse geniales y experimentados sin asumir demasiados riesgos. Esto puede empezar de a poco, pero puede empeorar rápidamente y llevar a tomar malas decisiones, y el precio que se debe pagar no vale la pena.

Nutrición óptima para el buceo 

Scuba diving demands not only physical fitness but also proper nutritional preparation. Like with any activity, we expend energy while diving; surprisingly, the energy required for routine recreational diving is somewhat moderate. Under unusually strenuous recreational conditions, however, it’s possible to burn more than 500 calories. 

A healthy diet is an asset for safe scuba diving as well as a beneficial lifestyle
