And Dave campaigned for nearly 25 years to protect Lyme Bay from scallop dredging, which was basically turning the rocky reefs , which harbored all these sunset corals and sea fans and all sorts of stuff that's pretty remarkable in Englishwaters-- it's not like a tropical coral reef , but it's as good as it gets for biodiversity in Britain, and therefore we need to protect it--
I'm going to argue that it's got four parts. Reefs with different kinds of environmental conditions in a diverse portfolio might give us a better end result.
I'm going to argue that it's got four parts. reefs around the world.
Even sea scorpions, these terrifying giant bugs that swam in the ocean were still around. Reefs were made out of these kinds of colonial animals that totally disappear at this extinction.The best place to see a reconstruction of the ocean life is a place I went to, the Permian Basin Petroleum Museum
No, it's a real thing. Reefing a sail is a real thing.We do have a close-up.
And the idea of having these guys come out of the forest, come away from the coast where they're protecting the coral reefs , and be able to address you, is the type of thing in which we take great pride, and the type of relationship whichmakes conservation sustainable and the fight against climate change possible and successful.
You've got to bring some oysters from somewhere nearby, not far away, ideally, and put them in, and they will replenish the reef , or so we hope. If they don't, Solent is pretty stuffed.
And they have four legs and a little lure between their eyes. The reef is relatively healthy compared to the rest of the Mesoamerican Reef .
This was a very typical reef . This reef got hit by a hurricane. It got hit by disease.
I have a feeling I can't confirm this, but I think part of the reason Flame became fixed on the waves of the Cortes bank was because there had been a report of a ship striking a reef 100 miles off the coast of California in the LA Times. And the story didn't get a whole lot of play. There were only a few mentions of it. But essentially I was lucky enough to find the commander Robert Leuschner and he told me about what happened. Basically the USS Enterprise slammed into the spot very near where the guys surf today and it was
I don't know if you realize what it means, but coral reefs are not just cool things, beautiful things with marvelous corals. Coral reefs are really the nursery of the marine biodiversity. In coral reefs , many fish, just-- I don't know how you say-- well, they take life in the coral reefs .
They're in the tropics, the water is clear, and there's very little nutrient in the water. Coral reefs have had to be really, really efficient to be able to grow there. And one of the things that corals have figured out how to do is by internally recycling those nutrients, they can be very efficient.
Now in the 1970s, people weren't really worried about the future of coral reefs . Coral reefs were doing just fine. But they were interested in trying to understand them.
I'm going to argue that it's got four parts. These reefs are probably interconnected with each other.
You can't find trees in the fossil record for almost 10 million years. Coral reefs are replaced by piles of bacterial slime that kind of had gone away since the Precambrian. It's just a totally extreme event.
Oh, sorry-- I skipped over this. Coral reefs are a huge concern. Coral reefs are calcifiers.
Coral reefs are a huge concern. Coral reefs are calcifiers. This is just a quote from some British marine scientists that it's likely that reefs will be the first major ecosystem in the modern era to become ecologically extinct.
Thereís only one dive boat I know that goes here, and one captain who knows it well. So itís pristine. You can see in this picture here. Itís just shallow reefs when youíre above one. Beautiful water. These are the corals that I was talking about. Theyíre very common corals. These are the kinds of corals you just swim by, because theyíre so boring. But you can get a very different view of these corals with
And I'm gonna take you to, what's this map of? : Coral reefs . Sanjayan: Coral reefs , great. So the lighter it is, the less intense the diversity of reefs are. So that's Hawaii, for example. That's the Caribbean.
Trash-- I'm kind of shocked, to be honest. Great Barrier Reef is my home.
There's this truce that is struck in a cleaning station that only happens in this very special place. Anywhere else on the reef and that moray eel will just eat that wrasse straight on. But somehow, they maintain this kind of agreement that that's not going to happen.
Someone will call me up and they say, Jeremy, I went to that toilet paper aisle yesterday and I thought about you. This is a reef off of the island of Ischia, which is off of Naples, Italy.
Or are we doing things today that's really going to prevent that? As a coral reef conservation organization, we want to figure out, OK, given that all these changes are happening, what can we do about it? So what I'll argue in my talk today is that there's really two key pieces we're going to have to figure out,
And the main way that a coral will do this is by building a rocky skeleton that it uses to overgrow other corals and take over space on the reef . You can think about like in a forest, as trees grow up, they grow over other ones and shade them.
Every single one of those reefs is made by corals and just a few other organisms that can do this trick of making rock out of water. The Great Barrier Reef is something like 1,400 miles long. It can be seen from space by the naked eye.
That's something you might see in California, which has highly productive coastal oceans. In a coral tropical reef system that's supposed to be something of an ocean desert, this is a sign that something is wrong. The seaweeds are getting out of control in this system, this is bad news for the corals.
I'm going to argue that it's got four parts. without causing the reef to decline over time.
I'm going to argue that it's got four parts. Corals across a whole reef will release this at the same time.
I'm going to argue that it's got four parts. and this reef , and this reef , and this reef .
I'm going to argue that it's got four parts. and the next reef .
I'm going to argue that it's got four parts. And that reef is going to get wiped out.
I'm going to argue that it's got four parts. rely on those reefs -- are making decisions about how to manage their reef that create a better environment for corals and a better environment for the rest
I'm going to argue that it's got four parts. That network of healthy reefs then can be a source of baby corals that can move from one reef , to another reef , to another reef ,
I'm going to argue that it's got four parts. to another reef in that network.
I'm going to argue that it's got four parts. where there's enough reefs with enough communities working to protect them that include a lot of that diversity that's present in the system, that's connected from one reef
She was this morning in Kimbe Bay in Papua, New Guinea, getting ready for a new survey in this part of the island. We study the coral reef ecosystem over all the Pacific for two and a half years. This is now. Back, 10 years ago, we studied the Arctic Ocean.
So we decided to put Tara for 2 and 1/2 years on an expedition to study over the same, over the same samples, repeated work over the 2 and 1/2 years to sample the reef , its surrounding waters, the organisms, the animals. And I can show you here the video-- please-- a crazy video showing you the super micro activity of coral reef .
So this will not disappear. But the reef will change-- how they will change? The system will change.
The US Coral Reef Task Force ended up introducing me when I would do my twice-a-year presentations from the task force as the new presentation from Morose Mark.
This is Capitol Reef .
The Barrier Reef is on the east side right there.
Glover's Reef is just the offshore atoll.
Glover's Reef , South Water Caye, and to helping the government of Belize and a number of their different measures, historically, to protect
use of the reef , do they use certain parts of areas over others?
use the strobes to fill as much as you can for these scenes that have subjects that go further off. But the strobes that weíre bringing are actually quite big, but they still donít light the reef up for very far. They like maybe six feet in front of you. We shoot super wide. A lot of fisheye. These reefs are from Raja Ampat, that same area. This is one of my favorite shots. Itís a giant clam in the foreground, reef in the background. This school of juvenile convict fish swimming around. Whatís interesting
This is a reef in Aceh in Indonesia a year ago prior to, a year and a half ago, prior to the bleaching event that bleached out 100 percent of certain species of corals, in a
I would point out, you know, these guys are surfing over the hull of the Jalisco. So that ship provides a hazard kind of unlike most other surf spots I've ever seen anywhere. slamming into the reef , it is so abrupt, which is why Mavericks is so hard to ride in a different way than Cortes. It hits the reef and then jumps out of the ocean to where it whips the
driven down into that reef and you're try to climb your leg R that's what we call it and if you have a big wipe out
The coral reefs are dissolving.
I was talking about reefer, you know-- smoking, getting high, you know?
