North Sea

Karlsruhe was a light cruiser which participated in Operation Weserübung, the invasion of Norway in 1940.

German WWII cruiser found between Norway and Denmark

Statnett, the Norwegian state-owned power grid operator, made the astounding discovery of the lost Karlsruhe cruiser around 488 meters (1,600 feet) below sea level off the Southern coast of Norway, some 13 nautical miles from the port of Kristiansand. Signs of wreckage were first detected three years ago during inspection work when sonar detected a shipwreck only 15 meters from an undersea power cable between Norway and Denmark.

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.

Ghost Fishing in the German North Sea

In May 2016, the dive team of the Dutch Ghost Fishing Foundation helped a German Greenpeace campaign, with the goal of drawing attention to the sizable problem of ghost nets in the North Sea. After almost two weeks of ideal weather conditions—with bizarrely bad visibility underwater—the deck of the Arctic Sunrise boasted five enormous BIG BAGs (the Swedish eco-friendly garbage bag brand) full of nets and fishing lines.

Battle of Jutland Centenary Expedition

It is hard to put into words what I was feeling at this stage. I was descending the shot line in approximately 15m visibility and an image started to appear. Not the random wreckage you often see, or even the straight lines of a cargo ship, instead these were two long barrels. This was no ordinary wreck—I was looking at the ‘X’ Turret of HMS Invincible.

A Story Of A Siebe Dive Knive

At exactly 03.00 on 22nd December 1986, oil production started on Gullfaks Alpha (A) in the North Sea. Gullfaks A is situated in the southwestern part of this oil field, and the first of three platforms to be installed. The idea was that Gullfaks A would primarily process the oil (separate water and sand out of the product) and then store it.

Just over one year later, there was an incident on a ship in this sector.

WW2 British sub HMS Tarpon found off Jutland

HMS Tarpon left Portsmouth on 5 April 1940 and ordered to Norway. On the 10th Tarpon was ordered to take up a new position but was never heard from again. Post War German records showed that Tarpon had attacked the Q-ship Schiff 40/Schürbek, but her first torpedoes had missed. A sustained counterattack that went on most of the morning finally brought wreckage to the surface and it became clear the submarine had been sunk.
