Issue # 20 An ocean feast
It’s the greatest show on earth – the endless struggle underwater to find food and to avoid being eaten. On every dive we enjoy this life-and-death theatre – from bait balls being picked off one-by-one by rapacious sharks, to manta rays hoovering up copepods, from swirling shoals avoiding predators, to gobies darting away from hungry mouths. In this issue, Douglas David Seifert’s focuses on predation. Plus a look at the pressures on the Galápagos, the confounding science of nitrogen narcosis, the best images from the Philippines and a stunning glimpse of diving under the ice in Greenland.

We all love to dive under the water, and a few hardy souls love to dive underwater when it’s frozen, but for those that do, the breathtaking seascape more than compensates for the drop in temperature. Tobias Friedrich follows champion freediver, Anna von Boetticher, under Greenland’s ice for a photo shoot that takes place on the same planet as the rest of us, but in a completely different world.
All day, every day, aquatic animals engage in a life-or-death struggle for survival, trying to find food to feed themselves without becoming food for others. There are very few species that don’t participate in the never-ending battle not to be eaten – and there are no prizes for second place. Douglas David Seifert breaks down the complex relationship between predators and their prey, with his stunning photography capturing the incredible action.
If there is one predator that outstrips all the rest, then it is humans. We take away the prey from predators and we prey on the predators themselves; stripping the ocean of its natural resources. Steve Jones reports from the Galápagos, examining how human activity is rampaging through the Cradle of Evolution. Can even the fittest survive?
What do underwater photographers really need? Flying cameras, of course! These days, all the best scuba diving movies and photo albums provide elevated context to the dive experience, but you no longer need a private helicopter and professional camera to film it. Mark ‘Crowley’ Russell takes a look at some of the best drones available for the travelling diver.
Most people learn about narcosis with stories about divers offering their regulators to fish, or seeing pink elephants sauntering along the reef. Sadly few of us ever see the pink elephants, but pretty much everybody will get narc’d at some point in their diving career. So what causes it? Colin Munro takes a look at the science behind nitrogen narcosis.
For our third Big Shot photo competition in partnership with Aggressor Adventures, we asked entrants to submit their best underwater shots from the Philippines for the chance to win a Philippines Aggressor liveaboard trip and the chance to be published in DIVE. Check out the winning entries from the hundreds that were submitted, exclusively in our Autumn 2020 print issue.
