Corals are getting sick all around the globe at alarming rates, and we really don't know how or why.

And it's using a device like this that I recently discovered that a known coral pathogen actually has the ability to sniff around the seawater and hunt for corals.

So these bacteria are very well adapted to hunting down these corals.

I'm currently testing different environmental conditions to see what scenarios make this pathogen more or less capable of hunting corals.

The Pulse Amplitude Modulated Fluorometer, or PAM, gauges the fluorescence of corals as it pertains to pollutants in the water as well as climate change-related issues.

But in town, where corals had died from overfishing, from pollution, the tropical storm picked up the dead corals and used them as bludgeons to kill the corals that were left.

Corals are born in a number of different ways, but most often by mass spawning: all of the individuals of a single species on one night a year, releasing all the eggs they've made that year into the water column, packaged into bundles with sperm cells.

And we found that corals, even without the biology involved, still prefer white and pink, the colors of a healthy reef.

We can choose to use the materials and colors and textures that might bias the system back toward those corals.

Now in addition to the surfaces, we also study the chemical and microbial signals that attract corals to reefs.

Starting about six years ago, I began culturing bacteria from surfaces where corals had settled.

And I tried those one by one by one, looking for the bacteria that would convince corals to settle and attach.

And we now have many bacterial strains in our freezer that will reliably cause corals to go through that settlement and attachment process.

This is one of my favorite corals, and always has been: dendrogyra cylindrus, the pillar coral.

We collected this, we got it back to the lab, we got it to fertilize and we got baby pillar corals swimming in our lab.

Whatever the cause, we have much more work to do before we can use baby corals to grow or fix or, yes, maybe save coral reefs.

There are brittle stars growing on these corals.

Those are things that look like tentacles coming out of corals.

There are corals made of different forms of calcium carbonate growing off the basalt of this massive undersea mountain, and the dark sort of stuff, those are fossilized corals, and we're going to talk a little more about those as we travel back in time.
