This is Abu Dhabi – home to some of the world’s most striking construction projects.
And there’s another one being built right here.
It might not look like much yet, but work is underway here to build a record-breaking aquarium,
one that will blow all the others out of the water.
The Shedd Aquarium in Chicago holds about 19M litres of water.
Chimelong Ocean Kingdom in China holds 49M, and is currently the world’s largest
but when Sea World Abu Dhabi completes, it’ll likely contain a whopping 58M litres of water.
That’s the same as 23.2 Olympic pools.
Designing and building a tank this big poses an extreme engineering challenge.
It has to withstand immense water pressure, let in the right amount of light for tens of
thousands of species to survive and immerse millions of visitors in an underwater world.
This is how Abu Dhabi is building the world’s largest aquarium
Every year, millions of people flock to Abu Dhabi for its white sandy beaches,
unique architecture, and world class resorts.
In the middle of it all there’s Yas Island, where tourists’ wildest dreams come true.
It’s a 25-kilometre strip of land packed with hotels, restaurants,
theme parks, malls, a Formula 1 track … and pretty soon – SeaWorld Abu Dhabi.
When its doors open in 2023, the marine-life theme park will span 183,000 square metres.
Inside there will be five floors of displays with more than
68,000 marine animals including manta rays, sea turtles, reptiles, and amphibians…oh my!
Unlike other SeaWorlds – this one won’t have any orcas.
But it will have this – the Endless Vista,
a 20-metre vertical window stretching up across several levels.
Now this isn’t just any old design challenge. The team has to construct a structure that millions of
people can pass through, and create a liveable habitat for thousands of different animals.
So called “immersive” aquarium design like this aims to replicate a natural environment,
and usually includes elements like artificial coral or rocks,
and little access to sunlight to prevent algae growth
Now the aquarium in Abu Dhabi will be a lot bigger than most.
So all of these factors, from strength to sunlight are going to be magnified.
But before we get into all of that, a quick word from today’s sponsor, Masterworks.
SeaWorld Abu Dhabi is part of a $3.2BN investment in new construction at Yas Island.
But the developer’s spending spree stands in stark contrast to the rest of the world,
where investors are seeing some of their worst losses in history.
$36 trillion in stocks and bonds were wiped out in less than a year.
And Goldman Sachs has told investors the classic
stock-bond strategy may not be enough for the future.
It’s already down an average 34% this year, its worst performance in 100 years.
Goldman Sachs’ ideal allocation for stocks has shrunk from 60 percent, to around 45.
But you can take that money you’re no longer investing in stock and put it into real assets …
… like fine art.
Goldman says this can protect your purchasing power,
even in the face of rapidly climbing prices.
In fact, the last time inflation was this high, art appreciated more than real estate
and even stocks, according to the Masterworks All Art Index.
Masterworks lets you invest in high-value contemporary
art from legends like Picasso and Banksy,
for a fraction of the full price.
When Masterworks resells a painting you’re invested in,
you get a share of the potential profits.
Despite massive losses in other markets,
Masterworks has sold 8 paintings, 5 this year alone.
Those sales produced net returns to their investors of up to 39 percent.
There’s a wait list to join Masterworks’ 575,000-plus members.

You’re probably wondering how aquarium glass like this doesn’t shatter from
the sheer pressure of millions of litres of water.
Well, big aquariums usually aren’t actually made of glass.
Instead they’re built with massive acrylic sheets called plexiglass.
That’s because acrylic is up to 17 times stronger than regular glass and half as dense.
It’s also clearer than glass and easier to bend into shapes like curves, tubes and bubbles.
Now acrylic isn’t just used in aquariums – you’ll also find it at your local hockey rink,
inside submarines and in aeroplane windows.
SeaWorld Abu Dhabi wouldn’t give us details on how exactly their tanks are being engineered,
but the acrylic walls at the Georgia Aquarium,
which has about half the capacity of the one in Abu Dhabi, are two feet thick.
And of course, there’s the question of exactly how to get millions of litres of water into the tanks.
We’re not sure exactly how SeaWorld plans to do it in Abu Dhabi,
but there are generally two ways this happens.
If an aquarium is landlocked, like the Georgia Aquarium in Atlanta,
millions of litres of tap water are pumped into the building and treated to remove chemicals.
In Georgia, the team added 680,000 kilo bags of instant salt to create a saltwater tank.
But if an aquarium is by the coast, you have the option of bringing in water straight from the sea.
California’s Monterey Bay Aquarium – yes, the one in Finding Dory – is located on the coast.
So they built two 16-inch pipes that sit just above the seafloor
of the Monterey Bay and pump up to 2,000 gallons per minute into the building.
That deep-sea water is full of nutrients like
nitrate and phosphate that allow marine plants and animals to grow.
But it also means a lot of barnacles, algae, and invertebrates can clog the intake pipes.
So every six weeks the team shoots large foam plugs through the pipes to clear out any growth.
This isn’t the first time the UAE has
kept new megadevelopments under wraps until they’re complete.
Over in Dubai, the world’s deepest pool was quietly constructed under a building
structure so that when it officially opened it dwarfed the previous record.
Just a year ago SeaWorld’s press releases said the new site would hold 25 million litres of water.
Today, the developer says it’s expected to hold 58 million litres.
This will be the first new SeaWorld marine-life park in more than 30 years, and if the UAE’s past
endeavours are anything to go off of, it’s going to be unlike anything we’ve ever seen before.
