On March 25, 2012, filmmaker James Cameron became the first man to visit the deepest spot in the ocean since U.S. Navy Lieutenant Don Walsh and Swiss oceanographer Jacques Piccard reached the Challenger Deep of the Mariana Trench – 35,800 feet below the surface – in the bathyscaphe Trieste in 1960.
While Cameron’s dive only offered views of a few hundred square meters of the ocean bottom, it was truly another great symbolic leap for mankind. If the space program had received financial support at the low levels of ocean programs, we’d never have reached the moon, we wouldn’t have a space station, and there would not have been a space shuttle program period.
Cameron’s achievement, more than anything, points out the lack of interest in the ocean and in ocean funding by policy makers.
When it comes to understanding the ocean, humans are metaphorically in a position a lot deeper than the Mariana Trench. While you might have know about James Cameron’s adventure, you might not know these important facts:
- Ninety-five percent of the ocean is unknown or unexplored.
- Only five percent of the ocean floor has been charted and most ocean bathymetry is based on satellite observations of the sea’s surface, resulting in a margin of error of 600 meters.
- As big as the ocean looks to humans, if the earth was the size of an apple, the ocean would only be as deep as the skin. More so, the Earth is vulnerable to the activities of seven billion humans.
- The ocean contributes $223 billion to the nation’s gross domestic product and is a huge part of national economies around the world.
- The ocean is the most critical link to understanding the dynamics of global climate change because of the relationship between the ocean, the atmosphere, the carbon cycle and the water cycle. As Admiral David Titley, the Oceanographer of the Navy, said: “The ocean is the dog wagging climate’s tail.”
So what is at risk if we as people, don’t better grasp a better understanding of the ocean?
- The inability to adequately predict changes in weather patterns and extreme events and prepare for the potential of sea level rise, shifts in agricultural productivity, and the dislocation of millions of people.
- Unrecoverable impacts to the marine ecosystem and the loss of a source of protein for the more than one billion people who depend on fish for that protein.
- Loss of present and future economic benefits. The ocean supports nearly 1.5 million establishments, employing 2.6 million people.
