sea life

Picture a young sea lion — let's call him Joey — taking an afternoon swim along the coast of Alaska and coming upon a long, shiny plastic loop.

Of course, Joey doesn't know the loop is plastic. All he knows is that he's never seen something like this wriggling through the water before, and he'd love to play with it.  

"Sea lions are curious and playful creatures by nature," explains Sue Goodglick, a wildlife biologist with the Alaska Department of Fish and Game program that studies and tracks Steller sea lions like Joey. So, she says, when they come across plastic objects like this, they usually like to play with it.

Joey is only 2 years old — a juvenile — so playing is his top priority right now. It's how he practices hunting and swimming so he can be prepared for whatever life throws at him.

He doesn't know this plastic thing isn't a glimmering fish or a fun piece of kelp but something dangerous.

It probably got to the ocean after someone a little too eager to open their package of new hair products tossed it carelessly aside after unwrapping the box. When people don't take time to properly discard plastic items like package wrappings, these items can end up on the street and make their way to the ocean through storm drains and other waterways. And even if people do toss such items in the trash, if they are not secured, they are light enough to blow away and right into Joey's path.

Curious, Joey uses his whiskers, mouth, and flippers to check out this potential new toy.

He almost looks like he's dancing as he turns his head upside down, somersaults, and bops the packing strap with his nose. But as he plays, this strap easily gets stuck around his neck, and without "hands" to pull it off, the loop stays put, like a plastic necklace.

Plastic bands like this one, usually made to wrap around cardboard boxes, are created to be durable, so unlike other materials, they take a long time to degrade on their own. In fact, nobody knows for sure how long plastic takes to break down in the ocean, but estimates say it likely takes decades — maybe even up to 450 years for larger plastic items.

This means that as Joey grows, that plastic "necklace" doesn't come off. Instead, it gets tighter and tighter around him, like a noose, cutting into his skin and muscles. This can lead to infections, slow down his range of movement, suffocate him, or cause starvation and death because he can't move around to find food.

Joey is far from the only sea lion to get hurt by plastic items. 8 million tons of plastic go into the ocean and hurt more than 800 species of animals every year.

These include marine critters like sea turtles, dolphins, whales, and fish. Some mistake plastic for food. Others, like Joey, get tangled up while playing or just swimming around. This is bad news for humans, too, because plastic has been showing up in our seafood after the fish we eat consume it.

"Many types of wildlife are simply unable to avoid encountering [marine debris]," Goodglick says, and Steller sea lions are one of them. Plastic packing bands like the one Joey found are particularly hard for sea lions to resist, making them one of the most dangerous and deadly plastic items. In fact, since 1980, the world population of Steller sea lions has fallen from 300,000 to less than 100,000 — and plastic packing bands are one of the reasons why.

Declining Steller sea lion populations can have a huge effect because without them, the ocean ecosystem where they live can be thrown off balance due to what scientists call top-down trophic cascade. Sea lions are top-level predators, so their eating habits affect the population and behavior of their prey. Without enough of them to keep prey populations in check, other ocean resources can become depleted. Not only that, but sea lion poop is also important in providing essential nutrients for ocean life.

This is why Goodglick is so dedicated and passionate about making sure that we all help prevent further harm to ocean wildlife.

"We all need to take action to prevent new marine debris getting into our oceans and help clear out what's already there," she says.

Making a difference doesn't even have to be complicated — we could all make a difference with a few simple changes.

We can "lose the loop" or cut items like packing bands before we throw them away. That way, if the item happens to cross Joey's path, it won't form a noose and entangle him.

We can also dispose of trash properly — recycle plastic materials, reuse them if you can, and secure garbage can lids so nothing blows away. And if we see someone else's trash on the beach, we still have a chance to grab and secure it before it ends up in the water for Joey to find. Plus, for those who live near the coast, there are always local shoreline cleanups looking for volunteers to help them get rid of the trash that's out there.

But wherever we live, being mindful of our behavior using and disposing of plastic is still important. "Remember our lands and oceans are connected!" Goodglick says. When we rely on single-use plastic for everyday items like water bottles, we create more and more trash that can find its way to water systems through storm drains.

You probably don't feel like a hero when you cut a plastic packing band. But for marine life like Joey, it can be a  life-saving act.

And that means you're actually doing a favor for all of the rest of us, too. After all, the ocean provides us with food and nutrients — it sustains all life on this planet. So when that adorable, playful sea lion called Joey can't even get through an afternoon swim without a piece of plastic threatening his life, that's a bad sign for the rest of us. It means we're not caring for the very ocean that keeps us alive.

But when we make a few simple changes to keep plastic out of the ocean, we ensure a healthy planet for all of us. And Joey gets to enjoy his playtime in peace, satisfying his curiosity for life with seashells, kelp, and the other natural treasures he's meant to find.

Heroes

Sea lions usually live in the ocean. So why are so many showing up on land?

Whether it's caused by El Niño or climate change, things aren't looking so great for some of our favorite marine mammals.

A week ago, a seal lion pup wandered into a fancy California restaurant.

It was an adorable story of a wayward pup at The Marine Room in La Jolla, California.

But it turns out the pup, nicknamed Marina, wasn't looking for hot brunch spot; she was looking for help.

When sea lions can't find food, they're forced to make their way to the shore to prevent from drowning. Sadly, on shore, there's not exactly a huge supply of food awaiting them, either.

Over the past few years, an inexplicably high number of malnourished sea lions have been washing up on California's shores, and nobody really knows what to do.

So far this year, 40 sea lions have been rescued in the San Diego area alone. Last year, nearly 1,000 washed ashore. Some suspect it has to do with El Niño, which has warmed the water and wiped out the sea lions' food supply —  anchovies, sardines, herring salmon, and plankton that are dying off — but this issue has been building for the past several years.

According to the National Marine Fisheries Service, the number of sea lions stranded ashore is 20 times higher than it was a decade ago. That's not good, and it's a sign that this is a much larger issue than simply El Niño. 

Climate change plays a big role in this potentially devastating problem.

If we want a long-term solution, we need to address climate change.

If you've been looking for a reason to care about climbing temperatures, how about for the well-being of the adorable sea lions?

Marina's story had a happy ending, but there are thousands of other sea lions still in need. Here's hoping they get help.

The poor little pup was starving. Luckily, Marine Room manager Matt Caponi and employees were quick to get the 8-month-old the help she needed, calling a SeaWorld rescue team. The sea lion has been given some food, shelter, and is expected to make a full recovery.

Have you ever thought to yourself, "Man, oxygen is so cool. It lets me breath, it keeps my heart and lungs healthy, who do I have to thank for this stuff?"

Well the answer to that is simple. Oxygen is produced by photosynthesis, which is why trees and plants get a lot of their due credit here on land.

But wait ... there's more!

Phytoplankton are the unsung heroes of all that delicious O2 we breathe.

Phytoplankton are mostly invisible to the naked eye and live in the ocean's surface. Just like trees and plants, these one-celled creatures soak up energy from the sun to convert carbon dioxide into nutrients. The byproduct of that process is fresh oxygen, which is released into the water.

Scientists estimate that phytoplankton actually produce about half the world's oxygen.

But, unfortunately, phytoplankton might be in some serious trouble.

A new study has revealed that phytoplankton populations in the Indian Ocean have decreased up to 30% over the last 16 years. Which is a big problem for those of us who enjoy breathing.

What's to blame for the plummet of the phytoplankton population?

According to the researchers, warming of the ocean's surface has led to a decline in ocean mixing — which is the process by which nutrients are carried from the ocean depths up to the surface. Phytoplankton die off when their access to these nutrients is restricted.

Because phytoplankton are a key part of a very complicated oceanic food web, the implications of their demise could be disastrous.

“If you reduce the bottom of the food chain, it’s going to cascade,” Raghu Murtugudde, an oceanographer at the University of Maryland in College Park told Science News.

When one part of an ecosystem disappears, the whole thing is in danger of collapsing. Murtugudde added that the decrease in phytoplankton may be partly responsible for tuna catch rates declining by up to 90% in the Indian Ocean over the last five decades.

The Indian Ocean has been steadily warming for years, taking a serious toll on the marine ecosystem.

The Indian ocean has become the place that absorbs the most excess heat generated by increasing greenhouse gases, according to a study conducted by climate scientists in India.

That study also shows that, currently, the Indian Ocean is projected to keep warming, while phytoplankton populations continue declining. This warm water has the potential to be carried to other oceans where it will have dramatic and lasting effects.

"If this warm blob of water in upper Indian Ocean is transported all the way to North Atlantic, that could affect the melting of Arctic sea ice," Sang-Ki Lee, a scientist at the Cooperative Institute for Marine and Atmospheric Studies told The Guardian. "That can also increase hurricane activity and influence the effects of drought in the US."

This problem might seem far away, but it actually hits extremely close to home.

Just because the decrease of phytoplankton is happening in an ocean in a different hemisphere doesn't mean people in America aren't affected by it.

It's also easy to forget sometimes that we human beings are an integral part of the world's ecosystems. Phytoplankton might be microscopic, but they play a huge role in our ability to live.

Not only do phytoplankton produce the oxygen we breath, they're also a food source for the fish we eat and a key part of the marine ecosystem that keeps our oceans thriving.

The Indian Ocean is now a case study for the oceanic effects of global warming, Murtugudde says. "[It] must thus be monitored closely for clues about the response of the marine ecosystems in the rest of the world oceans.”

We're all a part of the same planet. And that's not just a tree-hugging hippie slogan. It's a literal truth. We are affected by and connected to every living thing around us. Even a microscopic organism on the other side of the world.

There comes a time in all of our lives when we must admit the tragic truth: Sharknados are not real.

Sharks rain from the sky like teardrops from my eyes. GIF from "Sharknado 2."


Neither are Sharktopuses or Mega Shark and Mecha Shark or any other such fantastical creatures of SyFy Original Movie fame — except for two-headed sharks (which could arguably occur as natural mutations) and avalanche sharks (which, with climate change, you never know).

It's OK. It can be difficult accept the harrowing reality of our CGI-monster-less lives.

But dry your eyes, brave soldier! For hope has risen like a phoenix from the fiery depths of the South Pacific....

Scientists recently discovered a certain sharp-toothed surprise while exploring an active underwater volcano.

That's right. Underwater volcano.

Oceanographer (and National Geographic Society/Waitts Grant recipient) Brennan Phillips led an expedition into the South Pacific to learn more about Kavachi, a submarine volcano near the Solomon Islands that was actively spewing as recently as 2014.

Phillips and his team knew that the summit was somewhere around 100 feet below sea level and that it was capable of shooting plumes of magma nearly a quarter-mile into the air, forming temporary islands on the ocean's surface.

But no one had ever explored Kavachi up close before. They wanted to learn more.

Unfortunately, it's hard to study underwater volcanos. 'Cause, ya know. Underwater. And also volcano.

They sent underwater cameras to look inside the crater and discovered that Kavachi wasn't the only thing that was active.

There were vol-crab-nos...

...and lava-rays...

They were calling it a "sixgill stingray." But we all know the truth. GIF via National Geographic/YouTube.

And f---ing SHARK-CANOS!

That's right, I said shark-canos. As in plural, baby.

This one's called a "silky shark," and frankly, I don't blame him for hanging out in a submarine volcano because shark-cano is waaaaaaaaaay more badass than "silky shark." GIF via National Geographic/YouTube.

Yes, these hyper-evolved geo-aquatic mutant hybrids are real. But that's ... about the only thing we know about them.

"These large animals are living in what you have to assume is much hotter and much more acidic water, and they’re just hanging out,” Phillips said. "What sort of changes have they undergone? Are there only certain animals that can withstand it? [...] Do they get an early warning and escape the caldera before it gets explosive, or do they get trapped and perish in steam and lava?

While we have yet to witness any shark-canos riding like rockets out of the ocean on geysers made of molten rock, we have discovered their one major weakness:

It's us.

Shark attacks against humans are incredibly rarewe're talking maybe 30 a year, 40 tops. You've got about a 1 in 11.5 million chance of experiencing your very own "Jaws" encounter.

That's not at all. There has not been a single record instance of a shark-cano attack in the entirety of human history. This is likely due to the fact that it's hard for living people to make it 200 feet underwater into the belly of a volcano, but still.

For the most part, sharks are all like:

GIF from "Super Bowl XLIX Halftime Show."

and then us humans are all like:

GIF from "Snakes on a Plane," which isn't technically a SyFy Original Movie, but still counts in terms of absurd animal-based B-movies.

Humans kill more than 100 million sharks every year. It's gotten to the point where 1 in 4 shark species are endangered.

If the tables were turned, you'd be hiding in a volcano too.

There's a much better chance of survival down there, which when you think about it, is really saying something.
