Dieses bildreiche Sachbuch wendet sich auch an erfahrene Taucher, die neugierig auf Tauchen der anderen Art sind: Tauchen mit Haien, in Höhlen und Wracks, unter Eis und in starken Strömungen.
Part aspirational, part instructional, this book is for competent divers who wish to extend their horizons or push themselves to the limit.
Diving with Sharks and Other Adventure Dives covers diving with Great White, Hammerhead and other sharks, cave and wreck diving, and diving in strong currents and under ice.
Each chapter is a combination of specialised technical and environmentally aware diving advice, site information and stirring anecdote.
The dives featured range from established, accessible schemes such as dolphin dives in the Bahamas to exceptional expeditions such as an unrepeated cave-passage exploration.
Celebrating the diversity of diving as much as encouraging the pursuit of new challenges, this beautifully illustrated guide is a must for every qualified diver’s bookshelf.

Acknowledgments and Credits
Great Whites have long been hated and persecuted, but a new breed of eco-adventurer is fast realizing that this incredible predator is more than a simple killing machine; it is a great creation of nature. In 1991 South Africa became the first country to protect the Great White Shark and today, many people make a living from taking tourists, film crews and researchers to see this threatened species.
South Africa is thought to harbour the largest population of Great White Sharks in the world, with the highest concentrations occurring on the south and southwest coasts of the Western Cape, South Africa. The water here is usually between 13 and 19°C (55 and 66°F), creating the perfect temperate water conditions that this shark prefers.
The Great Whites spotted off the Cape typically measure around 3.5m (11.5ft), but every year a few intrepid adventurers may get to see the huge 5.5m-plus (18ft) females that are the reproductive future of the species.
For cage dives, the sharks are attracted using the chumming method. There are three prime viewing and dive sites in the Western Cape where, during the winter and early spring months (April through October), cage divers have an exceptionally good chance of seeing Great Whites, as they congregate in these locations each year to breed.
The first is Seal Island in False Bay, on the east coast of the Cape Peninsula, just a few kilometres from Cape Town. The sharks are attracted to its colony of 64,000 Cape Fur Seals and the abundant birdlife, while the surrounding mountain ranges create a scenic site for divers. The area was first opened for scientific study, and to a limited number of regular operators, in 1995.
It is unsurpassed for the observation of natural shark behaviour such as predation, due largely to the strict controls exercised over operators. Winter’s offshore winds clean and flatten the bay, and average visibility is around 8-10 m (26-33ft), reaching 15m-plus (50ft) on good days. Great Whites can be expected in varying numbers on a daily basis.
False Bay is home to a legendary shark, called the Submarine, estimated to be 7m-plus (23ft), and the more recently spotted Gin-plus (20ft) creature nicknamed Hercules.
The second site is Dyer Island, off Gansbaai, on the Cape’s south coast. This is the best-known site, due to the large number of operators working there (the first operators started up in 1991, with a major influx in 1996). Most of the diving takes place in a channel known as Shark Alley, with Dyer Island on the one side and Geyser Rock, supporting a seal colony, on the seaward side.
The shark-viewing season here is slightly longer, from March through November, and even in the summer months, sharks are sighted on a semi-regular basis by many of the charter operators. In this unprotected area, the winter winds whip up large mountainous seas, which first have to be negotiated to get to the site. On calm days, however, Dyer Island is a good dive site with visibility upwards of 10m (33ft) and sometimes 15m-plus (50ft).
A very select group of operators is based in Mossel Bay, 385km (240 miles) east of Cape Town. Cage diving takes place around a small seal colony based in a relatively sheltered bay that allows the running of expeditions on most days. Visibility here ranges from 5-20m (16-66ft), with water temperature the highest of the three sites. This year-round site peaks from April through October, while shark activity varies greatly in summer (November - March), although Great Whites are often spotted here out of season. (Dive operations close for the main summer holiday period in December.)
As divers enter through the door in the top of the steel cage tied alongside the boat, the bleating of the surrounding seal colonies fades once they enter the eerie silence of the Great White’s watery world. Waiting for that first glimpse of the untamed master of the ocean, the general feeling is one of excitement tinged with apprehension.
Then, unexpectedly, the broad, toothy smile of a shark glides effortlessly up towards the divers from the surrounding abyss, and the perpetual rocking motion of the cage is forgotten while awe holds them spellbound at the grace with which the huge animal moves. [...]
