Interviews: Dr. Robert Ballard Answers Your Questions 20

A while ago you had a chance to ask former Navy officer, professor, and famed ocean explorer Robert Ballard about shipwrecks, his work with the Ocean Exploration Trust, his learning programs, and what he's found on his expeditions. Below you'll find his answers to your questions.
Autonomous robotic vehicles
by kalpol

I've always imagined fleets of tiny, relatively inexpensive autonomous vehicles exploring the oceans, sending their data back to be aggregated and mapped. Are there any projects of this sort happening?

Dr. Ballard: Yes there are. Go here to learn more.



Most interesting problem
by overThruster

First, thank you for taking time to answer our questions and for the amazing work you have done both as an explorer and an author! My favorite book of yours to date is The Discovery of the Bismarck.

I have two questions:
What is the most interesting underwater engineering problem you've had to solve in your career?


Dr. Ballard: When we lost the HUGO/JASON system on its first lowering in the Mediterranean in 1989 and had to recover them from 3,000 feet of water and be back in the water for our live JASON Project shows to 250,000 students waiting for the broadcasts in less than a week.

What are the unsolved underwater engineering problems that you think are most important?

Dr. Ballard: Solving engineering problems are much easier than convincing “the community” to accept a new way (technology) of doing something.



SOSUS
by dciman

Loved the show you hosted a number of years about about the development and implementation of the SOSUS system. Can you speculate or comment on the types of next generation technologies that could potentially fill in some of the gaps we now have with the reduction in traditional SOSUS effectiveness against quiet(er) ships from other nations? Presumably we still have to keep track of other countries missile and attack subs, is that much harder now than in the past?

Dr. Ballard: Ocean bottom observations are spreading across the ocean floor and will eventually be commonplace making it difficult for submarines and unmanned vehicle to sneak up on us.



Pollution
by Anonymous Coward

Dr. Ballard --thank you for your exploration work, and for making science and oceanography exciting to all of us!

A question: during your exploration of the deep sea, how prevalent or visible are the effects of human activity, i.e pollution, noise from ships, increased acidity due to more CO2 on the atmosphere, and the like? Do we even know enough to see if we are affecting as a species these ecosystems as critically as those on the surface of the planet?

Thank you and best for you and your crew in future expeditions!


Dr. Ballard: It is not so much what we can see (plastic, coke cans, etc.) which is not that much in the deep remote areas we explore, it is what we cannot see like acidification of the ocean water, its increased temperature, and the presences of other chemicals we continue to dump into the sea that concerns me.



Iron Bottom Sound; Kirishima
by Shakrai

Dr. Ballard: You're probably better known for the discoveries of Titanic and Bismarck, but I've always been more fascinated by your expeditions in the Pacific, specifically Iron Bottom Sound. Would a follow up expedition with more modern technology be a worthwhile endeavor? I would most interested in seeing another exploration of Kirishima, since the circumstances of her battle damage and loss have recently come into dispute.

Dr. Ballard: We plan to return to Iron Bottom Sound in the 2018 timeframe so stay tuned.



Electronic still camera
by fnj

Are any of the Marine Imaging Systems deep submergence electronic still cameras (circa mid 1980s) still in operation? With or without the original Heurikon based topsides?

Please accept my appreciation for your enabling an important part of my career. My work with MIS and Marquest Group was a happy time of fond memory.


Dr. Ballard: To my knowledge those Marquest camera systems have been replaced but once you are “signed out” of a world you lose contact with what follows.



Danger
by Major Blud

I know that quite a bit of the exploration that you've done has been with ROV's, but you've also been down in the deep yourself in the Alvin submersible. Was there ever a time during one of your expeditions where you feared for your life?

Thanks for taking the time to answer our questions, and for helping to inspire my interest in science. I was a young when the Titanic and Bismarck were found, and I can still remember the excitement and wonder I felt during those two events.


Dr. Ballard: There were several times when I was diving in submersibles and bathyscaphe when I feared for my life of those of others when they were diving and I was topside – when the fire broke out in the ARCHIMEDE bathyscaphe during Project Famous in 1973, when ALVIN got stuck in a fissure in 1974, when we crashed into the side of a fault scarp in the Mid-Cayman Rise in 20,000 feet of water in the bathyscaphe TRIESTE II I 1977, and when the DELTA submersible became entangled in fishing nets while diving on the LUSITANIA.



Space
by GoCrazy

You've probably heard about NASA's potential exploration of planetary bodies with water (yes! real water!) such as Europa, which is known to have solid ice water on the surface, but possible liquid water beneath. Would you consider moving your expertise on oceanography to more space based programs, with the possibility that your discoveries on Earth could be the same on these other planets?

Dr. Ballard: I have been asked to help in the design of the Europa vehicle system and plan to visit JPL in the next month of so.

    I would've wanted a bit more elaboration on some of his answers, but certainly an intriguing interviewee. Going into a deep sea submersable take far more faith in engineering than I have - so props for that.

      That's what I thought too, then I looked at the original post and only about 20 people responded (really surprising). So there wasn't much interest and perhaps he felt it wasn't worth the effort.

    • There are those in oceanography who would tell you that Bob's submersibles are pressurized by his own overinflated ego. But I guess haters gonna hate. FWIW my grandpa met him once and speaks highly of him, and he answered a letter one of my cousin's wrote to him. And the JASON system is fucking rad.

        You can have a big ego if you can back it up. I only know of Mr. Ballard by reputation and by reading about what he's done but I don't think there is a long list of people who can match his accomplishments in his field. Sour grapes maybe?

    He sounds like a lot of fun at a party.

    You couldn't get Bobert Ballard?
  • I've heard Ballard lament on the state of the Titanic after tours put useless plaques down on the wheelhouse, etc. Surprised to see a lack of anyone asking how (or if) he is doing anything to help preserve the site, or if anything can be done. How does one archive and exploit a shipwreck by photographing/exploring a tragic scene, yet chastise others for bringing artifacts to the surface to protect them, and display them to a public that's curious because of the very exploration and photography that you in
    • How does one archive and exploit a shipwreck by photographing/exploring a tragic scene, yet chastise others for bringing artifacts to the surface to protect them, and display them to a public that's curious because of the very exploration and photography that you instigated?

      It's kind of the difference between photographing a grave site versus digging up bits of the coffin for souvenirs. The artifacts didn't need "protecting" and were only brought up for personal gain. (monetary, reputational, etc) It's the difference between cataloging a grave and plundering it. There is nothing wrong with finding out what happened to the Titanic. It's quite something else to exploit a tragedy for personal gain.

  • I notice he didn't touch that question about the American nuclear sub Scorpion. Too sensitive? Things they don't want us to know? A US Navy military grave? Or just the US Navy's sphere and he wants to stay clear?
