Is diving safe? This is a question as old as the sport itself and the potentially accurate answers fill an entire spectrum of responses. Over the past 17 years, I have studied this question intently, publishing numerous case studies and articles in addition to several books. In the last third of that period, this study was for the purposes of an academic paper in a degree program. Here is the definitive answer: It depends.

In January 2018, Barb Roy, our long-time associate editor and regular contributor, passed away after a long battle with illness. We celebrate her inspiring life and imagery in this memorial portfolio, highlighting some of the many beautiful and vivid underwater photographs Barb took during her frequent forays under the waves.

The current felt like the wind on a breezy day, and it was blowing me past the coral-covered sheer wall that disappeared over 60m (200ft) below me. Looking directly down, I noticed the color blue fading into slightly darker shades and finally into darkness, at the edge of how far I could see.

Until quite recently, the Red Sea was generally considered as the best place to see and photograph oceanic whitetip sharks—typically in remote locations such as the Brother Islands and Elphinstone Reef in Egypt or the isolated reefs of southern Sudan. Significantly though, these sightings are generally of lone individuals or very small groups and little is known about the overall population of oceanics in the Red Sea or their migration patterns.

In a previous article, I discussed some of the various definitions of learning, and focused on the following definition: Learning is a permanent, observable change in behaviour. Specifically, the article explored the second part of the definition and the learning outcomes that can be used to pin down the observable change in behaviour, which we are looking for. In this article, we will switch back to the first part of the definition: “a permanent change.”

Do we really need to go underwater at the other end of the world (and its challenges)? Lawson Wood poses this question while comparing the muck diving found in his home country of Scotland to that found in exotic locations in Asia and other regions of the world, renown for their muck diving sites.

Anemonefish are aptly referred to as "clownfish" because of their swimming behavior. It is interesting to note that the different varieties of clownfish exhibit very different characteristics. Some are shy homebodies, some can be very aggressive, and some even share their host anemones with other species.

During WWI, the mighty warship from the Austrian-Hungarian navy was attacked at an unexpected moment. The brave crew of two Italian torpedo boats did not falter and the Szent István was struck twice with deadly force.

There are many factors to consider when planning your dive trip, including the marine life, travel logistics, seasonal weather, ocean conditions and distance between dive sites. This is a lot to think about, and likely the reason so many of us, especially photographers, forget to consider one of the ocean’s most important processes when planning a trip—the tides.

Albert Einstein is quoted as saying, "as our circle of knowledge expands, so does the circumference of darkness surrounding it." In other words, in expanding our awareness, we just expose our ignorance. The more we come to know, the more we realise we do not know.

There are several ways to create dramatic images when you are shooting photos underwater: strong compositions, compelling behavior, exotic subject matter and of course lighting.
