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.)

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.

Interactive: Comparing Military Spend Around the World

Which countries have the highest military spend relative to their economy? This visual breaks down the amount spent in each country by GDP.

A map showing countries' military spend as a percentage of their gross domestic product.

Comparing Military Spend Around the World

One of the easiest ways to identify a nation’s priorities is by tracking its expenditures, and military spend is no different.

Usually spending is measured, and ranked, in absolute amounts. For example, countries around the world collectively spent $2.1 trillion on their militaries in 2021, with the most coming from the U.S. ($800 billion), China ($293 billion), and India ($77 billion).

But these eye-popping figures are best understood in the context of each country’s economy. Using data from the Stockholm International Peace Research Institute (SIPRI), Varun Jain has visualized 158 countries’ military expenditures, both as a percentage of their total GDP as well as in average per-capita spend.

Countries’ Military Spend as a Percentage of their Economy

To begin, Jain identified three categories of military expenditure as a percent of GDP, using the five-year (2018‒2022) average for more consistent data:

Military Spend% of GDPCountries
HighAbove 5%7
Medium2‒5%44
LowBelow 2%107

Under this categorization, the stand outs are the countries spending an outsized amount of their economic output on military, rather than the highest total spenders in absolute terms.

At the top of the table is Ukraine, which has earmarked a staggering average of 9.46% of its total economic output on defense over the past five years. That’s well ahead of second-place Saudi Arabia, which is slightly above 8%.

In Ukraine’s case, its high ranking shows how quickly priorities can change. From 2018 to 2021, the country spent 3.2-3.8% of its GDP on its military, but the outbreak of war with Russia saw its expenditures jump to one-third of economic output.

Other countries from the Middle East and North Africa follow in this tier, with Oman third at 8.11% and Qatar fourth with 5.88%. Rounding out the top seven high spenders are Algeria, Kuwait, and Israel.

The medium group consists of 44 countries and is led by four nations (Jordan, Armenia, Azerbaijan, and Lebanon) that all spend more than 4% of their GDP on their militaries. Other familiar countries known to have large military budgets, like Russia, Pakistan, the U.S., India and the UK, are also in this category.

The low spend group has a total of 107 countries, but also contains some surprises. For example, China, France, and Germany—all in the top 10 countries by absolute military spend—actually have similar amounts of military spend as a percent of GDP as Georgia, Cyprus, and North Macedonia respectively.

At the bottom of the table are countries with either low military importance, or strange technicalities. For example, Mauritius is one of the countries with the lowest military budgets because it doesn’t officially have a standing military, instead relying on two paramilitary forces (a special mobile force and a Coast Guard).

Similarly, Iceland allocates 0% of its GDP towards military spending. In place of a standing army, the country maintains a specialized peacekeeping force, a substantial Coast Guard, and relies on security alliances within NATO, of which it is a member and provides financial support to.

Ranking Defense Spending Per Capita

While the measure above equalizes military spend on economic strength, per-capita military spending shows how much countries allocate while accounting for population size.

On a per-capita basis (again using a five-year average), Qatar leads the ranks with a per-capita spend of $4,564, well-ahead of Israel at $2,535, and Saudi Arabia at $1,928.

Measured this way, we get a perspective of how small defense budgets can be per person, even if the total expenditure is large.

For example, India has the fourth-highest total defense expenditure in 2022, but because of its massive population only sets aside $53 per resident for its military, putting it solidly at the bottom third of the per-capita rankings.

Patterns Revealed By Measuring Military Spend

Changing how we look at a country’s military budget can reveal a lot more than just looking at absolute numbers.

For example, the Middle East is the region with the highest spenders on defense as a percentage of their GDP, giving us insight into regional security concerns.

Countries from the medium group of military spending—including parts of Eastern Europe, sub-Saharan Africa, and South Asia—highlight past or recent conflict zones between neighbors, countries with internal strife, or countries wary of a regional aggressor. Ukraine’s average per capita military spend, for example, was just $122.4 from 2018 to 2021. The next year, it jumped nearly 10 times to $1,018.66 per person after Russia’s invasion.

In fact, European military spending saw its sharpest one-year jump in 30 years as a direct result of the war.

Alongside European anxieties, ongoing tension between China and Taiwan has also contributed to increased military spending in Asia and Oceania. Will these budgets continue their dramatic ascent or will they rise evenly alongside their relative economies in 2023?

Data note: For these comparisons, the creator is calculating five-year averages (using data from 2018-2022) for military spending as a percentage of GDP and per-capita military spending for each country. The military expenditure data is pulled from Stockholm International Peace Research Institute.

Data for some countries is missing or may vary significantly from official figures. Countries with up to
two years of missing data had averages calculated on the years available, while countries with three or more years of missing data have been removed from this dataset, including: Djibouti, Eritrea, North Korea, Laos, Libya, Somalia, Syria, Turkmenistan, UAE, and Yemen.

Please see SIPRI’s methodologies page for more details on how they collect their data and create estimates.
