Deep Sea Exploration - JASON

By - Daphne Rave Ching

1. Greatest depth to which it can descend - Jason can descend to 6,500 meters                (21, 385 ft ) or just over 4 miles.

2. Inventor's name and year it was invented - Jason was built and operated by Woods Hole Oceanographic Institution (WHOI). Jason was first launched in 1988.

3. Number of people it can carry (if any) - Jason cannot carry any people during the long hours in the ocean. Jason has to be operated from a control room in the ship to maneuver the vehicles and monitor Jason's instruments and videos.

4. Length - It did not say how long Jason is in any of my resources, but Jason weighs about 8,000 pounds in air.

5. What sets it apart from other submersibles - The sensors, cameras and lights are tucked into the body of the ROV (Remotely Operated underwater Vehicle). The sensors collect water chemistry information such as salinity, dissolved oxygen, turbidity, and temperature. The three HD cameras provide 3 different views from Jason. Also, the longest dive the first Jason made lasted 117 hours. These are some of the features and facts that sets it apart from other submersibles.

6. Country who owns or operates it - Jason is operated by Woods Hole Oceanographic Institution (WHOI). WHOI is in Massachusetts, United States.

7. Type of data the submersible collects - Its manipulator arms can collect samples of rock, sediment, or marine life.

8. Type of technology used aboard it - Jason is propelled by six DC brushless electric thrusters that provide about 600 pounds thrust in the vertical, longitudinal and lateral directions.

9. At least one major discovery accomplished with it - The Jason system has also a successful career in underwater archaeology. A prototype named Jason Jr. was used to survey the wreck of RMS Titanic, and fully developed JAson visited a 1, 600-year-old Roman trading ship in 1989.
