Hello
I'm very curious about the coral issues in the ocean. I'm wondering how long would it take for the coral in the ocean floor to be recovered? Are there any way to be able to make new coral for the ocean?
thank you very much for your time

As I was reading about ocean acidification I came across comments by a lot of people who were under the impression that because the pH of seawater is above 7 (making it a base, and not an acid), ocean acidification was not only not a concern, but also that it doesn't really exist. Could you explain this more? By how much does pH have to shift for it to have noticeable effects on ocean life?

What inspired you to pursue a career in science? And what got you interested in studying the ocean, specifically?

I'm curious about the ocean's history. Do we know if the ocean has been as acidic as it is now becoming at any time in the past? If so, do we have any idea how it effected life in its waters? I wonder how this change may drive the evolution of ocean life.

Hi Gretchen I writting to ask you about the gossip about the The polar Ice melting. Won't all the fresh water melt and off set the acidity?

what critters/plants like a more acidic ocean or adapt well to those conditions? Where are we headed, basically?

What human actions do you think are the most likely to affect the acidity of the oceans going forward?

Is this world really just one big acid-base reaction.

Besides the Antartic seabutterfly, what other organisms are most affected by ocean water acidity?

Is it too late to stop the increasing acidity and temperatures of our ocean? It is my understanding that the effects we are seeing today are the result of "yesterday's" pollution. When today's pollution catches up with us tomorrow, won't it be an even more exponential issue? Is it too late?

i've heard about the ocean having a pattern of turning more acidic then more basic over its lifetime. what exactly or predictably is this pattern, every few hundreds of years? thousands of years? and it usually rebalances itself back out rights? of course it doesn't ever return back to the exact same, but how much of this is serious problems and how much of it is cycles of nature?
