Coccolithophore bloom off Brittany, France Coccolithophore bloom off Brittany, France (Jacques Descloitres, MODIS Rapid Response Team, NASA/GSFC/NASA)

Every day, every moment, an epic battle is raging across the globe. It's happening in the ocean. And the evidence is both highly visible and totally hidden, depending on your perspective. In this short, the tale of an arms race involving trillions of sea creatures--and why their struggle is vital to our survival.

Reporter Ari Daniel visits with Willie Wilson, who studies phytoplankton--aka microscopic plant-like creatures--at Bigelow Laboratory in Maine. There's a war in Willie's test tubes. A certain sort of phytoplankton known as coccolithophores are engaged in a surprisingly complicated arms race with deadly viruses. A virus is problematic enough when you're a human. Now imagine being a single-cell plant and mixing it up with the hugest virus you've ever seen. The coccos (as we've taken to calling them) are outgunned, but they won't go down with out a serious fight.

Ari and Willie explain how our itsy-bitsy heroes take arms against (literally) a sea of troubles--and how this battle, and others like it, make life on Earth possible.

1.which of the two viral life cycles are the viruses in this story following?
2. Do you have written transcripts of your show?

This was an excellent episode, but discussion of a possibly alternative view is needed: according to the NASA 'earth observatory' web page, the coccolithophores also release carbon dioxide back into the atmosphere, becoming part of the greenhouse problem and possibly causing 'the upper layers of the ocean to become more temperate and stagnant'. More information and perhaps some resolution of the 'friend (oxygen) or foe (carbon dioxide)' issue please!

Many thanks,
Harold Wood

Great episode! It's really interesting that it can be seen from space. Does anybody know where I could find a downloadable recording of the chemical "distress signal" sent out by the . . . critter . . . when it's infected? Thanks.

For those with an interest in some of the other attacks that coccolithophores face, they might read Jacqueline Ruttimann's article "Sick Seas" in Nature magazine's 31 August 2006 issue.

You asked where all the Carbon comes from. I assume you meant Carbon Dioxide which the phytoplankton "breathe". Well, just as the phytoplankton breathe in CO2 and expel oxygen, us humans (and other organisms) breathe in oxygen and expel CO2.

Aside from respiration, CO2 can also be generated from decomposing organisms, burning fossil fuels, and volcanoes, among other things. The original CO2 in the atmosphere most likely originated from the massive, and constant, volcanic eruptions of early Earth.

But if you meant Carbon, and not Carbon Dioxide, well then that element is generated by nuclear fusion in stars, and is then expelled upon their deaths. Neil deGrasse Tyson actually has a wonderful (if a bit lengthy) quote concerning this:

“Recognize that the very molecules that make up your body, the atoms that construct the molecules, are traceable to the crucibles that were once the centers of high mass stars that exploded their chemically rich guts into the galaxy, enriching pristine gas clouds with the chemistry of life. So that we are all connected to each other biologically, to the earth chemically and to the rest of the universe atomically. That’s kinda cool! That makes me smile and I actually feel quite large at the end of that. It’s not that we are better than the universe, we are part of the universe. We are in the universe and the universe is in us.”

Nice episode! However, I'm not convinced that the cycles of viral destruction and phytoplankton blooms are a "war we need." If there were no viruses, wouldn't the coccolithophores still thrive and make oxygen? Do they make more oxygen when they are growing?

This ties in nicely with the Fritz Haber episode in which 50% of the nitrogen in our bodies has gone through his process of nitrogen fixation.

So, Jad and Robert, where's all this carbon come from, eh?

I was listening to the pacebo episode specifically the doctor that cures the elephant skin on the young boy. The doctor thought that his confidence effected his hypnotism trials on all the other patience which is a good thought. I wonder however, since hypnotism is suggestion to the subconcious, so to speak (at least thats how I understand it), and the doctor says other patience flocked to him (expecting a cure). Could it be that in the minds of those patience they had already created in their minds great cure or action that would take place, effecting or essentially blocking the suggestion of the hypnotist. Just a thought sorry about my writing.

About Travis' question: Anyone know the classical music that backdrops Robert's introduction (around the 1:30 mark)?
I think it is the Sigfried's Funeral March portion of Gotterdammerung. The first time I heard it was not in the opera, but while watching John Boorman's 1981 film, Excalibur.

Could the music playing around three minutes twenty-seconds into the broadcast be provided. I would like to
get this version of the piece.

Thanks!

For some reason, I cannot make it through this entire episode without drifting off and doing something else. Sorry, Radiolab!

Amo el trabajo y la exploración sonora y científica que realizan. Los escucho desde México D.F. y disfruto cada entrega de "Shorts", pero "A war we need" es sublime, increíble, hermoso... Lo escuché 5 veces!!! Felicidades!!

Excellent, clear application of science to help us understand how and why the ocean is important. I sent the link to Prof Racaniello of "This Week in Virology" as a suggested pick-of-the-week for his weekly podcast.

I was quite disappointed . On average I love the show but this episode wasn't so awesome . . .

Great show as always. Quick question: where do I find that flash drive you mention at the start of the episode?

so this is what Thom Yorke meant by "And while the ocean blooms, it's what keeps me alive" in the song Bloom.

Radiolab: always hot. But this episode was a sizzler. Proof that science can be far more beautiful, far more awe-inspiring, far more brain-bending than fiction. Wow! LOVED this tale.

Wow, what an enlightening piece. The phenomena of virus repruduction is incredible in itself, but to learn that this process is responsible for my every other breath is beyond incredible. I would love to hear more from radio lab about our aquatic neighbors and their impact on human life.

I was so excited to see this story! But I have to admit I was a bit disappointed with the discussion of this cycle of coccolithophore-> virus-> phytoplankton-> virus etc. There is no discussion of grazing by zooplankton (<200 microns) which can account for the loss of about 67% of phytoplankton every day (average across the ocean)! Imagine 67% of your yard is eaten by a rabbit every day. This grazing often accounts for the "decimation" of the bloom, in phytoplankton at least.

@1984 The effect of temperature change and ocean acidification on plankton is a very active field of study at the moment. Ocean acidification could potentially harm the coccolithophores, which make their shells out of calcium carbonate, much like corals. Increased temperatures may change the rate at which the plankton (phytoplankton and coccolithophores combined) grow. The study of intersection of these 2 changes is actively being studied and hotly contested.

Thank you guys for all your work and energy! Really helpful to my life, as I'm sure many agree.

Great show.

Question about the production: what is the title of the classical piece that plays around the 1 or 2 minute mark?

Thanks!

Another great story! I had no idea so much of atmospheric O2 comes from the oceans. Thank you for the education, RadioLab.

Listening to this show was like finding a window in my house that I never knew I had!

Mar. 07 2012 09:16 PM

I hoped I would find a comment here from someone knowledgeable about the effect, if any, of ocean acidification and ocean temperature increases on phytoplankton. Now I have to google for myself.

I can't believe the first few commenters are so fixated on a word, rather than on the mystery and beauty of life. Thank you for such a great "short".

Ive been thinking about how cool an ocean related radiolab program would be! Awesome!

@allumley although that was the original definition of decimate, it was long ago updated to reflect common usage. Check Merriam Webster:

3 a : to reduce drastically especially in number <cholera decimated the population>
3 b : to cause great destruction or harm to <firebombs decimated the city> <an industry decimated by recession>

@al lumley

That's an extremely outdated definition of the word. Nowadays, decimate pretty much refers to the destruction of a large proportion (not even necessarily a majority).

On a side, I remember doing a report on coccolithophores back in my H.S. oceanography class. Good times.

Mar. 06 2012 02:56 PM
al lumley

- Please ! Please !! PLEASE !!! Decimated Actually means reduced by 1/10th , It is the improper use of the word
( by Journalists ) that has created the false meaning of near total distruction !!!
