10,000 Shipping Containers Lost At Sea Each Year
kkleiner writes "Right now, as you read this, there are five or six million shipping containers on enormous cargo ships sailing across the world's oceans. And about every hour, on average, one is falling overboard never to be seen again. It's estimated that 10,000 of these large containers are lost at sea each year. This month the Monterey Bay Aquarium Research Institute (MBARI) sent a robotic sub to investigate a shipping container that was lost in the Monterrey Bay National Marine Sanctuary in 2004. What's happened to the sunken shipment in the past seven years? It's become a warren for a variety of aquatic life on the ocean floor, providing a new habitat for species that might otherwise not be attracted to the area."
To add: If the Captain of any vessel orders it, (in an emergency) any containers they are carrying can be jettisoned to ensure the ship's safety.
Having worked helping customers move their personal possessions overseas, (mainly for oil & telecommunications companies) I can tell you we very rarely mention it. I have had many people as me if they can pack their kids in with their sofas though.
Reminds me of this story. Basically, 29,000 toy yellow ducks fell overboard as it was leaving China back in 1992.

Life is not for the lazy.
Many of these tend to float pretty much at surface level for days or even weeks. With surface waves, they are impossible to see from small craft but of course are massive and hard. They are a very well known hazard to cruising folk crossing oceans, and will readily hole and sink a fibreglass yacht, or even knock a keel off. Forward-looking sonar, if you've got it, can't see them because of waves.
There are thousands of people crossing oceans in smallish boats, and every year a few of them go missing due to shipping containers. They very thought of them makes a cruising yachtie's blood run cold.
