Journey to the Bottom of the Sea
|
The National Geographic Society recently named a group of leading explorers as its first group of "Explorers-in-Residence." Among them is oceanographer and underwater explorer, Dr. Robert Ballard. This past summer Ballard journeyed to the Black Sea to uncover secrets from ancient routes and more. What makes Ballard's latest mission so exciting?
Riverdeep Today interviewed Dr. Robert Ballard to learn about his expedition and his thoughts on exploration, education, and the JASON Project, which combines both. Ballard has over 65 underwater missions to his credit. From the Pacific Ocean to the Mediterranean, Ballard and his team of oceanographers, archaeologists, and marine archaeologists have uncovered some of the world's most fascinating hidden treasures from underwater volcanoes to sunken ships.
Preparations for investigating the Black Sea trade routes began in 1997 when Ballard led an expedition along the route between Carthage to Rome. He followed with another expedition in the Mediterranean along the coasts of Israel and Egypt.

what Ballard found along these ancient
trade routes.

Putting together an expedition of this magnitude involves cooperation between many fields of science, including oceanography, ocean engineering, archaeology, anthropology, maritime history, and marine archaeology. A group of experts in these fields accompanied Ballard.
Coordinating such an effort requires monthsmaybe even yearsof research, study, and preparation. Even when everything goes smoothly, obstacles still arise. For instance, Ballard explains, "wood bores [a specialized mollusk that eats wood] have removed and eaten all the exposed upper portions of these ships...they've sort of eaten a lot of history."
Hear
more details about this mollusk that
literally "eats away" at history.
What makes the Black
Sea unique, and what does Ballard believe
he'll find? Make a list of possible answers.
Listen to Ballard's explanation about
the Black Sea.
In October 2000,
Ballard and his team discovered a shipwreck that was almost
perfectly preserved. The wreck was found in about 1,000 feet
(300 m) of water. Ballard believes the ship sank approximately
1,500 years ago. In addition, the bottom of the Black Sea
revealed three other wrecks of trading vessels from between
the fourth and sixth centuries. The remains of terra-cotta
jars that were probably used for transporting wine or oil
were found on these ships.

Robert Ballard is a charter member of the National Geographic Society's new Explorers-in-Residence program. With the backing of the Society, the seven chosen explorers will continue their research and projects.
The first Explorers-in-Residence are historian/author Stephen Ambrose, ocean explorer Robert Ballard, anthropologist/botanist Wade Davis, marine biologist Sylvia Earle, naturalist Jane Goodall, high-altitude archaeologist Johan Reinhard, and paleontologist Paul Sereno.

The National Geographic Society asked Ballard to expand his mission to include searching for evidence of the great flood described in the Old Testament. The society's interest was heightened by the publication last year of Noah's Flood, a book written by two oceanographers. The authors claim that the area around the Black Sea may actually have been the site of that cataclysmic flood.
Last summer Ballard's team went 550 feet below the Black Sea to investigate. He found the ancient shoreline indicating the presence of a land bridge. But he found even more compelling evidence of a flood that may have occurred around 5000 B.C.
During last
summer's expedition, Ballard's team found
shells that turned out to have great significance.
Think of some reasons why shells might
be an important find. Now listen
to Ballard's response.

Columbus, Magellan, Byrd, Cortez, Lewis and Clark. Their names and discoveries are legendary. Why would the National Geographic Society want to "redefine exploration"?
When this same question was posed to Ballard, he remarked that he is often asked questions such as, "That's over with, isn't it?" "Didn't we do that in the eighteenth and nineteenth centuries?" "Aren't we done [exploring]?"
Ballard's hearty and enthusiastic reply: "We've only begun!"
Think about exploration in Ballard's terms. He points out that 71% of the planet is covered by water, and that most of our planet is unexplored. "Less than 1% of the world's oceans and seas have been explored!" While there have been "great discoveries made in this 1%," Ballard wants to know "what about the other 99%?" Ballard believes that the Southern Hemisphere, where most of the world's oceans are situated and which explorers have largely ignored, should be of great interest to explorers.
Can you think of
an amazing find that lies beneath the
deep sea, but provides "tremendous potential"
for future expeditions? Hear
Ballard's opinion.
Ballard concluded his remarks about exploring in today's world by saying: "There's a huge difference between exploration and science. Science comes after the explorer!"

Exploration and Education
|
|

When asked how education today can help prepare students to be explorers for tomorrow, Ballard replies that the goal is to "motivate and engage them, to excite them, to energize them, as well as their teachers." He believes that today's middle- and elementary-schoolers "are going to explore more of Earth and more of outer space than all previous generations combined."
Near the Galapagos Islands, Ballard discovered giant tube worms, some measuring over 4 feet long. Off the coast of California he found underwater volcanoes called "black smokers." He is credited with discovering numerous schooners and trade ships in waters from Lake Ontario to the Mediterranean Sea. Using a specially designed submersible and robot, Ballard and his team located and entered the wreck of the Titanic and photographed its interior.

Since its inception 12 years ago, Ballard's JASON Project has had "5 million children" accompany his missions to the depths of the world's waters and experience the thrill of underwater exploration.
Ballard notes that about 750,000 schoolchildren participated in JASON XI: "Going to Extremes." Of those, "a majority were girls (53%), 14% Hispanics, and 12% African-Americans," proving, he adds, "that anyone can play in this sport."
How is the JASON
Project changing attitudes about science?
