Map: Visualizing Every Ship at Sea in Real-Time

Published

on

The ocean is a big place, which makes it a pretty difficult thing to wrap our brains around.

It covers over 70% of the Earth’s surface, is home to millions of species of life, and it makes up 97% of all water on the planet. But, with this massive size and ubiquity also comes a significant challenge for humans interested in trade: it must be constantly traversed in order for us to move goods around.

As a result, millions of people hit the high seas each day to get cargo from one place to another. The vessels used range from tiny sailboats to massive oil tankers, some of which can get up to four football fields in length.

Every Ship at Sea

We previously posted an interactive map of shipping routes that used 250 million data points to show how boats moved across the ocean.

Today, in a similar vein, we highlight a website that tracks the world’s ships in real-time, providing a unique picture of what is happening at sea. Below is a screenshot from MarineTraffic and going there will allow you to see all major ships in real-time as they voyage around the Deep Blue Sea.

Every ship visualized

You may be wondering, does this really show every ship at sea?

Well, it might not catch your Uncle Steve’s sailboat off the coast of Florida, but this map will show all major commercial vessels. Any oil tanker, cargo vessel, cruise ship, or fishing boat can be spotted, and it makes for some interesting observations if you know where to look.

A Look at Oil Chokepoints

Upon loading the real-time map, the first thing we did was adjust the filters to only show oil tankers.

After all, we know that every day, about 18.5 million barrels transit through the Strait of Hormuz between Iran and Oman, and 16 million barrels go through the Strait of Malacca between Indonesia and Malaysia.

Here’s a screenshot of the Strait of Hormuz, showing only oil tankers. (Dots are tankers that are not moving, while arrows represent tankers that are currently on course.)

Strait of Hormuz

And here are the ships going through the Strait of Malacca, which at its narrowest point is only 1.7 miles (2.7 km) wide.

Strait of Malacca

If you want to get oil from the Persian Gulf to the South China Sea, this strait is vital – otherwise a big ship must detour thousands of miles around the Indonesian islands of Sumatra and Java to find the next suitable waterway.

Coast of Somalia

Compare those above straits to the coast off of Somalia, where piracy and hydrocarbon theft are major concerns.

Somalia

All is pretty quiet, aside from the one daring tanker that is about 500 miles (800 km) east of Mogadishu.

Antarctic Cruises

One other easy observation?

It’s the few passenger boats hanging around the Antarctic Peninsula – which is the part of the continent closest to Argentina and a destination for cruise ships.

If you have a chance, check out the live map for yourself and play around with the filters. It’s also interesting to see what’s happening in your local waters, as well.

Mapped: Fossil Fuel Production by Country

These four animated cartograms show the nations leading the world in fossil fuel production, in terms of oil, gas, coal, and total hydrocarbons.

Published

on

Fossil fuels exist as a double-edged sword for most countries.

On one hand, they still make up a dominant piece of the current energy mix, and oil is still seen as a crucial resource for achieving geopolitical significance. It’s also no secret that fossil fuels are a driver for many economies around the world.

But with governments and corporations counting carbon emissions and mounting concerns about climate change, reliance on these same fuels will not last forever. As attitudes and policies evolve, they will continue to see a reduced role going forward.

Visualizing Fossil Fuels by Country

So, which countries are pumping out the most hydrocarbons?

Today’s cartograms come from 911Metallurgist, and the animated maps resize each country based on their share of global fossil fuel production.

Below, you’ll see four cartograms that cover oil, gas, coal, and total fossil fuel production.

Crude Oil Production

The United States leads this category, producing about 18% of the world’s total oil:

Oil production by country

Although the U.S. is the number one producer globally, it should be noted that the country doesn’t have the same quantity of oil reserves as other leading nations.

Weirdly, Venezuela has the exact opposite problem. The country has the most oil reserves in the world, but currently only sits as its 12th biggest producer.

Natural Gas Production

In terms of gas, the U.S. leads again with a 20% share of global production. Russia is also a gas powerhouse, with a 17.3% share.

Natural gas production by country

After the U.S. and Russia, it’s a fairly steep dropoff in terms of natural gas production. Countries like Iran, Canada, Qatar, and China are the next most significant players, but they each only produce 4-6% of the global total.

Coal Production

Coal use may be on the decline, but China still produces a whopping 45% of the world’s coal.

Coal production by country

China’s current relationship with coal is an interesting one.

Every year, coal has become less important in China’s energy mix – in 2011 it represented 70% of energy consumption, and by 2018 it had fell to 59%.

Despite this meaningful progress, China’s economy has grown so fast, that coal use has essentially held steady in absolute terms. Meanwhile, the country’s production of coal has actually grown slightly over the same timeframe.

Total Fossil Fuel Production

Finally, here is the sum of all three above categories, converted to metric tonnes:

Total fossil fuel production by country

The United States produces 20% of all global fossil fuels, with Russia and Iran rounding out the top three. After that comes Canada, which produces just under 5% of all fossil fuels globally.

Visualizing the World’s 100 Biggest Islands

See the world’s 100 biggest islands in a side-by-side comparison. Then, we look to see which islands have the highest population densities.

Visualizing 100 of the World’s Biggest Islands

View the full-size version of the infographic by clicking here.

When you think of an island, the first thing that might come to mind is a small, sunny beach surrounded by warm waters. But did you know that 11% of the world’s population actually calls islands their home?

Today’s data visualization is designed by mapmaker David Garcia, and it ranks the hundred largest islands found around the world by size.

Islands in the Stream

The 100 biggest islands range from the likes of expansive Greenland to independent Guadalcanal, the largest of the Solomon Islands. But look a little closer, and you’ll see just how much the top contender outshines the rest. Greenland is almost three times the size of the second-biggest island of New Guinea, and you could fit over 408 Guadalcanal islands within it.

In the visualization, the islands are also tinted, depending on the climate they come from. Blue islands are from the polar regions, turquoise islands lie in the temperate zones, and green islands represent the lush tropics. Which of these regions hosts the most islands?

It’s the Island Life for Many

North America dominates with 32 islands out of the top 100, but there’s a catch — twelve of them are uninhabitable, thanks to the frigid Arctic temperatures.

Throw the number of people into the mix and the regional overview gets even more interesting. Compared to the rest of the world, Asian islands are teeming with life.

  • 28 Asian islands
    Total population: 510.4 million
  • 14 European islands
    Total population: 83.8 million
  • 32 North American islands
    Total population: 40.7 million
  • 12 Oceania islands
    Total population: 18.3 million

Taking things a step further, we’ve remixed the visualization based on population density.

Biggest Islands Sorted by Population Density

The most populated island in the world, Java is filled to the brim with 141 million people — that’s over a thousand people per square kilometer. This is in part thanks to the capital city Jakarta being located on the island, but experts warn those days may be short lived. By 2050, scientific models predict that 95% of the city may be underwater, and that Indonesia must scramble to find a new capital.

To finish, here is the 20 most dense islands on the list, in terms of population density.
