Interviews: Ask David Gallo About Ocean Exploration

samzenpus posted about a year ago | from the deep-sea-discussion dept.

Earth 35

David Gallo is an oceanographer and Director of Special Projects at the Woods Hole Oceanographic Institution. He has participated in expeditions to all of the world’s oceans and was one of the first scientists to use a combination of robots and submarines to explore the deep seafloor. As a member of James Cameron’s Deep Ocean Task Force and the XPrize Ocean Advisory Board, David actively encourages the development of new technologies for ocean exploration. With more than 8 million views, his TED presentation entitled Underwater Astonishments is the 4th most viewed TED Talk to date. David has agreed to come up for air and answer any questions you may have. As usual, ask as many as you'd like, but please, one question per post.

Dave, how big was the cock you were sucking under there?

Chilling (3, Interesting)

syphax (189065) | about a year ago | (#43423877)

What's the most chilling thing you've observed underwater? By "chilling," I mean: some really weird-looking, previously unknown creature, remains of the Titanic, a squid attacking an ROV, etc. By "observed" I mean either directly, by video, or by evidence (e.g. ROV with large sucker marks)

Have you ever run into Dirk Pitt? (1)

ScentCone (795499) | about a year ago | (#43423949)

Can't help but wonder if that insufferable busy-body, Dirk Pitt, has managed to get under foot in the work you do. Sure, he's usually saving the world from man-made catastrophes and evil plots and whatnot, but he seems to leave a huge wake behind him. Just wondering if NUMA's budget wouldn't be better spent farming out more of their work to you guys at Woods Hole, which would also keep him from wrecking an endless parade of irreplaceable classic cars, boats, and aircraft.

Beneath the Beneath? (2)

eldavojohn (898314) | about a year ago | (#43424097)

Something that has often perplexed me is fossil distribution through time and tectonic shifts. For example, one can go to the middle of North America and find sea fossils. So, perhaps with your knowledge of what happens to things in the deep, are there untold fossils lying under the seabed floor? Perhaps a localized population of what once used to be land animals situated such that we have never seen these fossils at the vast bottom of the Pacific Ocean? If you can fill me in on why this is or isn't possible (I have no idea what plate shifts do to the top layer or what effects untold pressure has on fossils), I would be extremely interested! Thanks!

I'm sure Dr. Gallo can expand on the topic, but just as a quick reference for you, the sea floor is generally not very old: http://en.wikipedia.org/wiki/Seafloor_spreading

Why does Obama want crime victims defenseless? (-1)

Anonymous Coward | about a year ago | (#43424129)

Semi-auto weapons were used to kill approximately 500 Americans last year..and Obama wants them banned.
According to government stats, 25 people are killed each day by illegal aliens (that's 9,000 people a year)..and Obama wants to legalize them. Does anyone at all believe gun control has ANYTHING to do with saving lives????????

Acidification (4, Interesting)

Some Answers on WHOI's Site (1)

eldavojohn (898314) | about a year ago | (#43424219)

Have you noticed any affects of acidification of the world's oceans?

Well, it would be interested to hear his first hand accounts (if any) but his institute has a page devoted to it [whoi.edu] with a FAQ that may provide some more information on observables [whoi.edu] such as:

Will ocean acidification kill all ocean life?
No. However, many scientists think that ocean acidification will lead to important changes in marine ecosystems.

As well as:

Isn't it better that we sacrifice the oceans and let them keep on taking up CO2 and buffering climate?
Ocean acidification and climate change are two sides of the same coin. Both are direct consequences of anthropogenic CO2 emissions and cannot be separated from each other.

Those are just the beginning of longer answers but there's a lot of data on that FAQ if you're genuinely interested in this.

"Ocean acidification and climate change are two sides of the same coin. Both are direct consequences of anthropogenic CO2 emissions"

Bullshit, you can prove none of this and you know it. Don't pass off this crap pretending it's true as if everyone believes you. We do not.

Re:Some Answers on WHOI's Site (1)

GonzoPhysicist (1231558) | about a year ago | (#43425671)

It's very simple chemistry, when you increase the CO2 in water it turns into carbonic acid.

Re:Some Answers on WHOI's Site (-1)

Anonymous Coward | about a year ago | (#43426091)

What's the matter, you can't read you stupid moron?

Prove it "Both are direct consequences of anthropogenic CO2 emissions".

Fuckwad.

Re:Acidification (0)

Anonymous Coward | about a year ago | (#43425807)

Related question: Can you speculate on the effect, on deep sea hydrothermal vent ecosystems, of present day global climate change or any of the five historical mass extinctions (ordovician, devonian, permian, triassic, K/T/dinosaur killing asteroid)? Might these ecosystems serve as repopulation reservoirs (somewhat like recent speculation on the purpose of the human appendix re intestinal flora)?

My naive impression is that the conditions at one of these hydrothermal vents are so extreme that a few degrees increase in surface/atmospheric temperatures or ocean acidification as in present day GCC might be mostly irrelevant. If some of these vents are basically spewing out 600 degree supercritical sulfuric acid, what's another few degrees or ppt of carbonic acid?

Human Ocean and Sea Habitability Possibilities (3, Interesting)

Tha_Big_Guy23 (603419) | about a year ago | (#43424935)

Having watched the show SeaQuest as a teenager, and recognizing the participation from the Woods Hole Oceanographic Institute (For the first season anyway), I wanted to ask about the feasibility of humans actually inhabiting the oceans and seas as depicted in the television series. I realize that the technology to bring the ship itself to reality is quite a bit ahead of where we are now, but do you think it's possible in the near-future that humans will begin to colonize the oceans?

Re:Human Ocean and Sea Habitability Possibilities (1)

Don't live where you dump your trash, so no, no we wont.

Alvin replacement? (1)

dj245 (732906) | about a year ago | (#43425063)

Back in 2008, WHOI was working with Lockheed and the American Bureau of Shipping [wikipedia.org] in developing a replacement/successor to the Alvin submarine. What happened to that project and how will WHOI develop its underwater exploration capability in the future?

New Discoveries? (0)

Anonymous Coward | about a year ago | (#43425119)

Hello,
Something I hear about often (and which I think is a shame) is how very little of the ocean has been explored, and how ocean research as a whole does not receive as much funding or widespread attention as it should. But is there a particular section of any ocean, or any particular species, which you would like to see more attention given to, based on the potential knowledge we could acquire from researching that area or species?

ROVs and AUVs (1)

GonzoPhysicist (1231558) | about a year ago | (#43425739)

It's very difficult for me to see a reason for send human beings exploring when the state of remote and autonomous systems is improving so rapidly. What organizations and platforms show the most promise in this field and where is the most improvement needed?

More, please (0)

Anonymous Coward | about a year ago | (#43425881)

OK, I've seen your short TED talks, and some of that material has been covered in various NOVA or Nat Geographic episodes, but frankly that's just not enough. Seems to me you must have, or be on your way to, more than enough material to support a Cosmos-level miniseries on the deep sea. Are you aware of any plans to do such a series? Or alternatively, what is in your opinion the best current popular documentary episode or series that I should watch?

Have you disturbed the resting place of Cthulu yet? Was he, like, super-pissed? I guess we'd know by now, but thought I'd check.

Sensory system (1)

I know that some animals/fish/insects are extra sensitive to various fhenomena: electric filelds emmited by animals (hammerhead sharks), magnetic field of earth (birds, cats...), others are sensitive to vibrations (catfish), some others to sound or heat... What can You tell about the sensory system of deep sea creatures?

g01d4 (888748) | about a year ago | (#43428627)

Seems like the ocean would be an ideal environment for pushing the technology of autonomous operation and AI. That is, do you foresee the ability to create robot explorers that are a nerdy version of flying monkeys?

Re: Aquarius, Dead Zones, & Methane Hydrate (0)

Anonymous Coward | about a year ago | (#43429033)

I'm interested in Physical Oceanography, Inertial Navigation, Hydrophones & DSP. I'm currently building ROVs and beginning to build AUVs. Where within these fields would additional effort best advance the interests of protecting the oceans? What areas are most deficient in resource allocation or supplier competition?

Challenger DEEP's Future Mission (1)

minibnz (2591295) | about a year ago | (#43429981)

I saw an announcement that James Cameron has donated the Challenger Deep Submarine to WHOI, As one of the lucky people to work on this vehicle during its construction, here in Australia, I was wondering if you can tell us if there is any plans to use this Awesome Machine to explore any other parts of the planets Oceans. or is it destined to sit on display in a museum? I know how much hard work went into that machine, it would be a shame to not use the MOST Capable deep sea diving vehicle on the planet, to its fullest potential.?

Sunken ships drifting underwater? (2)

twosat (1414337) | about a year ago | (#43430835)

Many years ago, when I was aged about 12, I recall reading about a ship that had sunk and was drifting around underwater. I have heard about shipping containers doing this sort of thing, but I was wondering if you had ever seen a ship or a boat drifting around underwater.

Beneath the floor. (0)

Anonymous Coward | about a year ago | (#43431999)

1. Have you seen what materials e.g. lies beneath the ocean floor's flora and fauna?

-

1.1 if yes, till how deep have you seen it?

1.2. if no, why are you making this and spending your money on it? quite useless in my eyes.

- Follow-up.

1.1.1 If yes + amount 1.1.1 where did your vision stop?

- Follow-up

1.1.1.1 if yes, was there another floor beneath the floor?
1.1.1.1.1. were there moving objects such as animals?

this will be enough for now.
