Questions & Answers

Q: What causes shipwreck graveyards in the Graveyard of the Atlantic?

The Graveyard of the Atlantic is formed by the meeting of the Labrador Current and the Gulf Stream, which creates treacherous currents that bring many ships to the area. Additionally, the shifting sandbars and complex shoreline of the region add to the navigational challenges.

Q: Why are shipwrecks common along the Skeleton Coast?

The Skeleton Coast, located in Namibia, experiences winds that blow from the south, which transport water away from the shoreline due to the Coriolis force. These winds, combined with upwelling of cold water and the formation of dense fog, make navigation difficult and increase the risk of shipwrecks.

Q: What factors contribute to shipwrecks on the Great Lakes?

The Great Lakes are prone to sudden weather changes, particularly fierce storms that develop when cold arctic air from Canada combines with moist low-pressure systems from the Gulf of Mexico. These storms, powered by the relatively warm water of the lakes, create dangerous conditions for ships.

Q: How was the problem of Ripple Rock, a notorious shipwreck spot, resolved?

To mitigate the danger caused by Ripple Rock off the coast of Canada, a tunnel was dug under the seabed and up into the core of the rock. Over 1300 tonnes of explosives were placed in the tunnel and detonated in 1958, removing the rock and creating a safer passage for ships.

Summary & Key Takeaways

  • Shipwreck graveyards, like the Graveyard of the Atlantic, are marked by treacherous currents caused by the meeting of the Labrador Current and the Gulf Stream, making it a high-risk area for ships.

  • Sable Island off the coast of Nova Scotia is another shipwreck graveyard due to its dense fog, which made navigation difficult before modern technology.

  • The Columbia River Bar, located at the border of Washington and Oregon, is a dangerous area where the Columbia River meets the ocean, causing unpredictable currents and shifting sandbars.

  • The Aral Sea in Kazakhstan and Uzbekistan experienced an ecological disaster due to the diversion of rivers for cotton farming, causing the lake to shrink, leaving behind abandoned boats and a contaminated desert landscape.
