Aircraft Wrecks of Gran Canaria

For over a year, I had been looking forward to a very special expedition that was planned for May 2014. But as you know, life does not always go the way you plan. The expedition was postponed, and once again, I had to find an alternative, at relatively short notice.

After getting some interesting offers in March 2014, I met a rebreather diver from Gran Canaria at the Dive and Travel Show in Madrid. He suggested that I come to Gran Canaria for wreck diving.

Black and White Underwater Photography

People like color. Is any photographer not familiar with the delighted exclamation of the viewer: "Oh, this is so colorful"? This point also applies to underwater photography; the task of creating colorful underwater pictures is the goal (and passion, in some cases) of many. But then there is also good ol' black and white photography. Yes, even underwater!

Some readers may surely be shaking their heads now, wondering what is the point of depicting a colorful underwater scene, or a sea creature, in black and white?

Christmas Island: Australia's Own Galapagos

So here we are. Five divers and I, hanging at a depth of 18m, about 80m from the reef edge over an unfathomably deep drop off, looking at each other. Did that just happen? Did we just have a rather intimate close encounter with the largest fish in the world? Apparently so.

We were alerted to this gentle giant’s approach by our dive guide Hama, who, hanging out in the blue, spotted the gentle giant approaching and alerted us with a crazy rattling of his tank-banger.

Diving Dumaguete in the Philippines

Dumaguete sits down close to the southern tip of Negros Island in the middle of Visayas Island group in the Philippines, approximately 500km south of Manila. A coastal province, it is bounded on the east by the Bohol Sea and the Tañon Strait, which serve as a natural border to the neighboring provinces of Cebu, Bohol and Siquijor.

Dumaguete seems to follow only two seasonal changes: dry and wet. June through September is the Philippines’ monsoon season, and as you might expect, conditions are warm and humid. April and May are actually the hottest time period, with average maximum temperatures that can reach 34.3°C.

Frank Walsh Portfolio

An avid scuba and free diver, American self-taught artist Frank Walsh has captured his intense fascination of the sea and its creatures in brilliant, dynamic marine life paintings and sculptures for over 30 years. X-Ray Mag interviewed the artist to gain insight into his art and creative process, and how the underwater world inspires his creations.

"I strive for accuracy and want to know all there is about the subject I paint. The best way to do that is to dive into that world."

— Frank Walsh

Japanese Giant Salamanders

The Japanese giant salamander is a quite unique, if rather mysterious, creature that lives in rivers across western and southwestern Japan.

As both its common and Latin names (Andrias japonicus) suggest, it is an endemic species of Japan that is both protected under federal legislation and formally nominated as a special natural monument because of its cultural and educational significance.

Macro in Mozambique

There’s a cartoon that pops up on social media every now and again of a diver photographing a tiny starfish on a rock as a beautiful shark glides above him. The diver continues to concentrate on the critter as his buddies try, without success, to catch his attention. Such is the life of a macro photographer, and such was my recent experience in Mozambique.

I have been diving in Ponta do Ouro, a small Mozambican coastal village 10km from the South African border, since 2002 and love its laid-back atmosphere, rustic village life, long sandy beaches and warm blue ocean, just waiting to be explored.

PFO: Not the “Hole” Story

Researchers took a close look at PFO and arterial bubbles and reached some quite startling conclusions. Most divers know that many people have a PFO and that having a PFO makes you more susceptible to decompression sickness (DCS), but that is far from being the “hole” story, (forgive the pun).

The Scuba Confidential column in this issue is again adapted from my book, Scuba Physiological: Think you know all about Scuba Medicine?

Scotland's Islands of Forth

The entrance to the Firth of Forth, an estuary in southeast Scotland, is guarded by a number of islands, the two largest and most popular for diving being the Isle of May or May Isle, 7km (4.5 miles) from Crail in Fife and the Bass Rock, or The Bass, located 2km (1.2 miles) offshore and 5km (3.1 miles) northeast of North Berwick in East Lothian.

Although May Isle is only 57 hectares, it has been a National Nature Reserve since 1956 and is internationally important for its seabird and seal colonies. This small island has over 200,000 breading seabirds, as well as over 90,000 puffins; the island is honeycombed with their burrows.

St Croix: Changing Tides on the Caribbean Isle

St. Croix is known for nesting leatherback sea turtles but has recently become known as one of the islands through which Hurricane Maria passed. However, life on this US Virgin Island reaches beyond the tales of these two stories.

St. Thomas, St. John and St. Croix comprise the US Virgin Islands on the northeastern side of the Caribbean Sea. St. Croix is isolated from the other two islands.

The Evolution of Dive Planning

“Plan the dive and dive the plan” has long been the mantra employed in all areas of diving. Technical divers in particular spend more time planning their dives than many recreational divers. This is due to a number of factors, including increased risks, greater depths, high gas usage at depth, increased decompression obligations, increased oxygen toxicity loading and a host of other reasons.

In the early days of technical diving, there were no PC planning tools or dive computers suitable for technical dive planning. The only option for planning a dive was to look up a decompression schedule using pre-generated tables.

Die Unterwasserwelt des Vierwaldstättersees entdecken, ohne nass zu werden: Ein Hergiswiler bietet neu einstündige Rundfahrten im einzigen U-Boot der Schweiz an.

Der Hergiswiler Franz Hattan (65) ist Berufstaucher und verdient damit seinen Lebensunterhalt. Doch jetzt möchte er sich mit U-Boot-Fahrten ein zweites Standbein aufbauen. Im vergangenen Jahr hat er sich dafür ein passendes Gefährt gekauft: ein U-Boot, das 6,8 Tonnen schwer, 5,8 Meter lang und 2,3 Meter breit ist. «Es gibt in der ganzen Schweiz kein zweites immatrikuliertes U-Boot», sagt er stolz.

Wracks, Fische und Felslandschaften

Ab August soll das U-Boot in den Vierwaldstättersee abtauchen. Es bietet Platz für vier Personen und soll ein einmaliges Erlebnis werden, schreibt die «Luzerner Zeitung». Auf der einstündigen Rundfahrt sind drei Passagiere an Bord. In einem Radius von 300 Metern möchte Hattan seinen Gästen die Unterwasserwelt näherbringen. Er wird bis auf den Grund abtauchen, dieser liegt an der tiefsten Stelle rund 215 Meter unter der Wasseroberfläche. «Bei guten Sichtverhältnissen sieht man alles bis zu einer Distanz von etwa 15 Metern, Wracks, Fische, aber auch interessante Felslandschaften», verspricht der Berufstaucher.

Fahrt kostet 200 Franken

Die Fahrten will er in den Monaten August und Oktober anbieten. «Dann ist die Sicht sehr gut und ich kann es beruflich einrichten», sagt er. Im Siebentagerhythmus können so zwölf Personen in die Unterwasserwelt eingeführt werden. Die einstündige Fahrt kostet 200 Franken. Die ersten Buchungen über seine Homepage sollen schon bald möglich sein.

Das U-Boot hat Hattan für einen sechsstelligen Betrag gekauft. Eingesetzt wurde es auf dem Bodensee und für Staudammkontrollen. Damit das Unterwasserboot auch für Passagierfahrten fahrtauglich ist, müssen noch mehrere Arbeiten ausgeführt werden. Es werden neue Batterien eingebaut sowie eine leistungsstarke LED-Beleuchtung und ein Positionierungssystem, das das Boot genau orten kann.

Rege Nachfrage

Hattan ist schon vor einigen Jahren mit einem kleinen U-Boot auf dem Vierwaldstättersee abgetaucht. «Die Passagiere stiegen jeweils begeistert aus, waren fasziniert von der Technik und überwältigt vom Anblick unter Wasser», erinnert er sich. Darum ist er überzeugt, dass das Angebot auf rege Nachfrage stossen wird.

Die Sicherheit stehte an erster Stelle: Ein Schiffsführer überwacht mit einem Boot oben die Fahrt des U-Boots. Ein Kommunikator bleibt mit dem U-Boot-Führer in Verbindung. Für den Fall einer Panne ist auch vorgesorgt. «Wir können auf verschiedene Systeme zurückgreifen, um im Notfall mit einem schnellen Auftrieb das U-Boot an die Oberfläche zu bringen», erklärt Franz Hattan. Sollte dies nicht klappen, so sind im U-Boot Lebensmittelvorräte eingelagert und reichlich Sauerstoff ist ebenfalls vorhanden. Um ein U-Boot zu steuern benötigt es eine spezielle Bootsprüfung.
