coral

This is what it looks like when a piece of coral dies.

This is a phenomenon known as coral bleaching, now captured in the award-winning documentary "Chasing Coral." To get these impressive shots, a team of photographers, divers, and scientists traveled the world to capture time-lapse photographs of coral bleaching events.


"The beauty with time-lapse photography is that you have the ability to shift how we as humans see and perceive changes that may move in the slow lane," says photographer Zack Rago.

Getting these images was a challenge. Divers had to spend hours each day battling the currents. And it could be emotionally difficult too.

"Being the person on the ground experiencing those changes is certainly emotionally taxing. I have a deep connection to coral reef ecosystems. Spending as much time as I have documenting their death is something that fills me with guilt and shame to this day," explains Rago. "At the same time, I also cherish those dives because I know that our team has revealed this issue to the world in meaningful and powerful way."

When asked if there was any single dive that was especially hard, Rago says yes. "There is one dive that was particularly difficult. In the hours leading up to the dive, I actually watched the first edit of our time-lapses. Seeing the images from day one and immediately going back out to those dying reefs was the single most emotionally challenging dive I’ll likely ever do."

Coral bleaching happens when the water around a reef becomes too warm.

During a bleaching event, the coral polyps (tiny creatures that actually make the reef) are effectively cooked, slowly turning white before dying. It doesn't take much, the episodes captured in Chasing Coral were the result of only a two-degree rise in water temperature, according to The New York Times.

Once the coral is dead, brown, sludgy algae take over, turning the once vibrant reef into something that looks like a parking lot.

This deadly warming is fueled by climate change, as more than 90% of the excess heat in our atmosphere is absorbed by the ocean.

"Coral reefs are in trouble. We know that if current trends prevail, we will lose the majority of corals on the planet in the coming decades," says Rago. Scientists have warned that, given current trends, we could lose most corals within 30 years. Vast swaths of the Great Barrier Reef (where these photos were taken) may already be past the point of no return.

Rago is planning to head back to the Great Barrier Reef this November to help identify "super corals" that could help scientists breed heat-resistant reefs.

As climate change becomes the new norm, it can be difficult to remember how the world once looked.

"We need to protect what we can right now," says Rago.

There are already a lot of exciting efforts underway. Nations around the world are currently rallying around stopping or mollifying the effects of climate change, with 169 different countries joining in on the landmark Paris 2015 climate agreement.

As they work out the best way to stop this, photography like these amazing time-lapse images can be a touch point for us — something to stick in our minds. And, if we fail, they can be a record for future generations.

"This problem may be hidden in our ocean, but the solutions start with us," Rago says. By sharing these images, people can help inspire friends, family members, or business or political leaders to action.

"Chasing Coral" premiered on Netflix in July 2017 and is still available to watch as of this writing.

The team was also able to capture a weird, rare event known as coral fluorescence, which is well worth a watch. If you'd like to find out more about the film, you can visit their website.

Abalone Caye is a small island off the coast of Belize, and for about a week, it's home to an important group of kids.

The island, located in the middle of the Port Honduras Marine Reserve, is home to a small research station where five local college-age kids eat, work, and live together for a week each summer before heading back to the mainland.

There's a good reason for this expedition: These kids are in training to become community reef researchers.

The Community Researcher Training Program is managed by James Foley and the Toledo Institute for Development and Environment (TIDE), an environmental institute in Belize. TIDE manages a large swath of natural areas in southern Belize, including the Port Honduras Marine Reserve. And the students, who all come from local communities, conduct research that's vital to helping us protect our coral reefs.

They learn how to do scientific research that'll help TIDE monitor and protect the reef, such as taking underwater fish counts, going out with fishermen to weigh their catches, or doing surveys of the local markets.

Foley also teaches them professional-level scuba diving as well as teamwork, which can be really important since the work means they may have to stay out on boats (or tiny islands) for hours or days at a time.

Nice, right? But let's pause for a second and zoom out. Because big picture: Our reefs are in trouble, and they desperately need good management.

Coral reefs are an amazing ecosystem, but climate change is disrupting the little animals that make reefs, causing a potentially fatal problem known as coral bleaching. What's more, poor fishing practices means that reefs have been overfished, polluted, poisoned, trawled, and even blasted with dynamite.

Looking at all these problems caused by people, it's tempting to say, "OK, fine, we'll just close them off and keep everyone out." But that's neither realistic nor fair. Communities rely on these reefs for food and income, so managed access to the reefs is necessary in most areas around the world.

But managed access isn't just about limiting the number of fishermen — it's about studying and monitoring reef health and making policy changes as necessary, which is where the Community Researcher Training Program comes in. If we can head off problems like overfishing and pollution, we can help keep reefs healthy.

Foley's program has been successful because local communities don't always trust outsiders who come in and start telling people to change.

Often these communities have been living next to and with reefs for generations. They have deep cultural, historical, and economic ties to the reefs and their way of life.

So when a foreigner comes in – who hasn't lived there, whose family hasn't spent years fishing there – and starts ordering people around, it's understandable that locals would be mistrustful.

Foley has experienced this firsthand. He said that when he first arrived at TIDE, he'd try to talk to locals the conventional way, gathering locals into a room with graphs or discussions about trends and trying to tell them about changes they needed to make. But his words weren't always received well.

"People would be standing up, interrupting me, and saying 'You don't know what you're talking about. I've been fishing here all my life, and my father before me,'" Foley said.

And outsiders aren't always the best candidates for the job anyway.

Some research or management organizations rely on foreign volunteers, but doing that can come with drawbacks. You can't always count on volunteers having a lot of scientific training. Outsiders might also not understand the local environment or culture.

Even if the outsiders are highly trained professionals, it can still be a problem. Foley mentioned seeing otherwise good science derailed by a lack of local knowledge — some bit of information the scientist missed but that all the local fishermen knew by heart.

And at the end of the day, they don't live there. While a force of foreign volunteers might care deeply about the reef on an emotional or intellectual level, they don't live with it or depend on it for their livelihoods like the locals do.

That's why putting scientific power in the hands of these local kids is an awesome idea.

In fact, many of the same fishermen who were initially distrustful of the program are now on board.

"We've actually had now fishermen standing up in meetings and saying, 'Five years ago, you telling me this, I wouldn't have believed it. But now my own daughter's collecting the data,'" Foley said.

Some of the students in the program are on an academic track already, but others are children of local fishing families and "second-chancers" — kids who've been in trouble with the law or dropped out of school and need another opportunity to succeed.

Foley's been doing this since 2011, and he says the entire program is a win-win. Even if the students don't end up as researchers themselves, they end up with a highly desirable skill set; some have since become tour guides, members of the coast guard, or even TV presenters. And they can still sometimes be called in to help from time to time, too.

This isn't just feel-good fluff, either: Good community management might be the key to saving reefs.

In July 2016, the academic journal Nature published a worldwide survey of coral reefs. The most interesting things they found were called "bright spots," places where reefs were doing substantially better than anyone expected.

The bright spots weren't just remote, humanless areas either. Some were located right next to huge human populations and fished heavily. So what was the link between the bright spots? Where there were bright spots, local communities were actively involved in monitoring and protecting the reef.

Programs like these may end up being the heart of future reef conservation.

"It's really all about empowering local communities to participate in the management of their natural resources and building trust between the communities," said Foley.

So in the future, if you go diving and find yourself surrounded by magnificent schools of fish, sea turtles, blooms of color, and all the other signs of a healthy coral reef, you might want to remember and thank these community researchers.

Once upon a time, there was coral.

Coral lives in the ocean and forms massive, magnificent reefs when it binds together. The reefs, with their hard bony structure and various nooks and crannies, provide protection and shelter for all manner of marine wildlife.

Then algae came bouncing along, and something beautiful happened.

Algae, one of the oldest lifeforms on the planet, had been drifting through the ocean waters for millions of years, attaching itself to anything it could in order to reproduce.

Algae found a home with coral, and the two quickly fell in love.

Coral provides carbon nutrients and protection for algae, and algae provides food for coral through its photosynthesis. It's a perfect symbiotic partnership, and algae and coral found out they were a match made in heaven. On Earth. In the ocean.

For hundreds of millions of years, coral and algae's relationship has been rock solid. But times are unfortunately changing.

You know how sudden, massive changes in your life can put a stress on your relationship? Like the loss of a job or a death in the family? Well, the same thing can happen to coral and algae.

When the couple's environment experiences sudden changes, coral reefs can get stressed out, which affects its ability to be the good, supportive partner algae fell in love with. The algae is then forced to abandon the coral and seek out a better life elsewhere in the sea.

This is a process known as coral bleaching.

One of the largest coral reefs in the world, the Great Barrier Reef in Australia, has been abandoned by almost all of its algae.

It's one of the most significant coral bleaching events ever recorded and possibly the biggest oceanic celebrity breakup since South America left Africa in the great Pangea split.

Currently, 93% of the Great Barrier Reef has been left by its algae — a scarily high number, one which has never been seen before.

Who's to blame for this deep-sea Shakespearian romantic tragedy?

One of the most significant coral stressors is changing ocean surface temperatures. The "photosynthetic efficiency" of coral and algae's millennias-old lovefest drops if temperatures become too warm or too cold.

Lately, human-made climate change has pushed ocean surface temperatures way above normal. Australian ocean temperatures are also greatly affected by El Niño, which has recently become more extreme as a result of the greenhouse warming of the planet.

That temperature shift has forced algae to pack its bags and leave the Great Barrier Reef cold, lonely, and in serious danger.

To be fair, parts of the Great Barrier Reef will regain their algae population when (or if) ocean temperatures drop back down. But scientists have already seen large portions of the reef permanently die due to the sudden loss of algae.

Global climate change will also continue to produce temperature extremes unless we do something about it, meaning that coral stressors will become worse and worse every year, and these bleaching events will become even more significant.

There are 8 billion reasons to fight climate change. Now there's one more.

One of Earth's oldest and best love stories is coming to an end off the coast of Australia, but fighting back against climate change can save it.

If you don't want to do it for humanity, do it for Earth's greatest couple. Do it for a partnership that deserves to continue.

Do it for love.
