Trekking Canada’s Sub-Arctic Region in Manitoba
Rob entered with a splash and we descended to 16 meters (55 feet) at the top of a flat pinnacle in Button Bay not far from the town of Churchill. Visibility gradually increased with depth, unlike the water temperature, which decreased to 2.7°C (37°F).
So, where do we start? And what type of camera do we buy? Should we go for the DSLR (Digital Single Lens Reflex)—basically a digital version of the old single lens reflex (SLR) camera where you compose your photograph through the lens of the camera—or should we go for a compact point-and-shoot camera, which has live-view screening.
The other type of camera, which comes in two different versions, is the manufactured PHD cameras (Press Here Dummy). These are essentially point-and-shoot cameras with a large continuous viewing screen on the back, so you are actually composing your photograph by use of the movie screen.
Diving is an activity that appeals to a huge selection of people, and within diving, there are almost as many ways to enjoy the sport as there are participants. During the 1990’s scuba diving became a mass participation sport.
While the barriers to this underwater world were gradually being broken down, a small group of experienced divers were starting to push the limits of traditional recreational scuba diving. This movement, which has been christened ‘technical diving’, started off with just a few dedicated individuals. Over the last few years, this area has seen a huge increase in interest, and now a significant number of divers are moving towards technical diving.
You wonder, sometimes, how things link up. For example, how is a scuba diving suit connected to the likes of household names such as Dr Who, Casino Royale, Trainspotting, Star Wars Episode I: The Phantom Menace, Basic Instinct II, Atonement and the latest Ridley Scott/Russell Crowe epic, Robin Hood?
It’s been more than 20 years since film director, Nicolas Roeg, gave Mike Valentine his first break filming Oliver Reed and Amanda Donohoe in Castaway. “I was in the Seychelles for almost two months, shooting and directing all the underwater sequences from a script that contained only two lines of description. The result was more than six minutes of screen time, something I still feel lucky to have achieved at that time” Valentine grinned.
From a marine archeology and scientific standpoint, the Baltic Sea is a paradise. There could be as many as 100,000 shipwrecks dating back centuries in this dark and mysterious sea—Viking ships, trading ships and warships to name a few. No other place in the world is comparable to the Baltic Sea.
The wrecks, and structures found in the sea are veritable time capsules lying in wait for us to explore and expand our understanding of the past. It is also a comparatively quite shallow sea.
