Searching out shipwrecks

Earlier this month, a company called Odyssey Marine Explorations Inc. announced that it has discovered the sunken wreck of the S.S. Republic, a steamer that went down in a hurricane off Savannah, Georgia, on October 25, 1865, carrying $400,000 in $20 gold coins–worth $120 to $180 million today. There was a time when sending a …

The colossal squid

I don’t know how you feel about calamari, but it’s always been a little too rubber-band-like to be one of my favorites. However you feel about it, though, I’m pretty sure you can agree with me that it’s far better to eat calamari than to have the calamari eating you. That unsettling prospect was raised …

Sharks

It’s that time of the year again. The weather is turning cooler, the leaves are changing color, Canadians are leafing through travel brochures featuring sandy beaches, blue water, and warm sunshine. Except… …except, there’s been a lot of news about shark attacks coming from those very same sunny beaches. Some could be excused for wondering …

Submarines

  Submarines have been much in the news lately. Not only has world attention has been riveted on the tragic sinking of the Russian submarine Kursk, but Canada is in the process of getting new submarines and, in the U.S., the Civil War submarine that was the first to sink another ship has just been …

But most people don’t know about a third station designed to allow humans to live and work in a hostile environment–not space, but the sea. It’s called Aquarius, and recently a team of six “aquanauts” completed an eight-day …

Black smokers

Deep beneath the oceans, continental plates grind together. Sea water seeps into the ocean floor, contacts superheated rock and roars back out through hydrothermal vents. Surrounding those vents, darkness, pressure, poison gas and heavy metal, acidity and temperatures ranging from freezing to hot enough to melt lead create a zone that would instantly kill most …

Icebergs

They say that a movie is only as good as its villain, and the new movie Titanic, now packing people into theatres all over the world, has a whopper: a giant block of ice that tears open the “unsinkable” ship’s hull and, a couple of hours later, send it to the bottom. Icebergs have bedevilled ships …

Scuba diving

Now that winter has descended upon us in earnest, many Canadians are planning a trip south to Florida or the Caribbean, where they’ll bask in the warm sun, eat exotic foods–and maybe even try a little scuba diving. “Scuba” is a word in its own right now, but originally it was an acronym for “Self-Contained …

The ocean

I’ve always been fascinated by the ocean: the endless rolling of the waves, the water’s changing moods, the limitless horizon. Or maybe it’s just because, coming from the dry prairies, I’m amazed that anything can be that big and wet. How big and wet? The ocean covers 71 percent of the Earth’s surface: 361 million …
