Shipwreck Expeditions

Shipwreck Expedition Association

Our diving adventures have spanned many years.  We started at a time when diving equipment was a rarity and difficult to come by.  There were no dive centers and no one was offering dive trips. In the ensuing years the dive industry has expanded exponentially and there are dive shops in virtually every city.  Dive equipment and techniques are light-years ahead of what they were when we began.  Now you can go online and book a diving adventure in every corner of the globe.  The seas and oceans are open for us to explore!

Our website was created to pique your interest in underwater exploration and  history and show you where the two  meet. The history and exploration of shipwrecks are for us much more than a passion. For a long time people have looked at shipwrecks from a different point of view. Over the years this changed from looking at wrecks for what we could get from them to looking at them as living history to be photographed, video-taped and studied for their historical significance.  Many of the wrecks we survey are a mystery.  Often times we don’t know how they arrived at their resting places and often do not even know their names.

For divers who enjoy history and who have a desire to take it to the next level there is still an entirely new world waiting to be discovered. Diving as a detective is perhaps the most difficult type of diving because it takes a great deal of time and effort and does not guarantee success.  For those who simply love a mystery and what goes into solving it the reward can be very great.

We don’t see shipwrecks as steel or wooden debris littering the bottom of bodies of water, we view them with the respect they deserve and work towards their protection.  Every shipwreck is a living museum behind which is an amazing story that is waiting to be discovered.  We can all make a contribution to saving the white pages of history, and the inaccessibility of the environment in which we operate gives us an advantage and opens up amazing possibilities.  Let’s use it because there is still so much to discover.

We encourage you to take the plunge and explore the deeper history of shipwrecks and to document and publish your discoveries. Please contact us to share your findings today!
