Sailors have been circumnavigating the high seas for centuries now, but what could be found beneath the sunlit surface of the ocean remained a mystery until far more recently. In fact, it wasn’t until 1875, during the Challenger expedition, that humanity got it’s first concrete idea of how deep the ocean actually was.
Today’s graphic, another fantastic piece by xkcd, is a unique and entertaining look at everything from Lake Superior’s ice encrusted shoreline down to blackest, inhospitable trench (which today bears the name of the expedition that first discovered it).
The graphic is packed with detail, so we’ll only highlight a few points of interest.
Deep Thoughts with Lake Baikal
Deep in Siberia, abutting a mountainous stretch of the Mongolian border, is the one of the most remarkable bodies of water on Earth: Lake Baikal. There are a number of qualities that make Lake Baikal stand out.
Depth: Baikal, located in a massive continental rift, is the deepest lake in the world at 1,642m (5,387ft). That extreme depth holds a lot of fresh water. In fact, an estimated 22% of all the world’s fresh water can be found in the lake.
Age: Baikal (which is listed as a UNESCO World Heritage Site) is estimated to be over 25 million years old, making it the most ancient lake on the planet.
Clarity: Interestingly, the water in the lake is exceptionally clear. In winter, visibility can extend over 30m (98ft) below the surface.
Biodiversity: The unique ecosystem of Lake Baikal provides a home for thousands of plant and animal species. In fact, upwards of 80% of those species are endemic, meaning they are unique to that region.
Who is Alvin?
Since 1964, a hard-working research submersible named Alvin has been helping us better understand the deep ocean. Alvin explored the wreckage of RMS Titanic in 1986, and helped confirm the existence of black smokers (one of the weirdest ecosystems in the world).
Though most of the components of the vessel have been replaced and upgraded over the years, it’s still in use today. In 2020, Alvin received an $8 million upgrade, and is now capable of exploring 99% of the ocean floor.

The Ocean’s Deepest Point
The deepest point in the ocean is the Mariana Trench, at 11,034 meters (36,201 feet).
This trench is located in the Pacific Ocean, near Guam and the trench’s namesake, the Mariana Islands. While the trench is the most extreme example of ocean depths, when compared to surface level distance, it’s depth is shorter than Manhattan.
Obviously, the context of surface distance is wildly different than vertical distance, but it serves as a reminder of how narrow the “explorable” band of the Earth’s surface is.
The ancient Greek word, ábyssos, roughly means “unfathomable, bottomless gulf”. While there is a bottom (the abyssopelagic zone comprises around 75% of the ocean floor), the enormous scale of this ecosystem is certainly unfathomable.
Objectively, the abyssal plain is not the prettiest part of the ocean. It’s nearly featureless, and lacks the panache of, say, a coral reef, but there are still some very compelling reasons we’re eager to explore it. Resource companies are chiefly interested in polymetallic nodules, which are essentially rich manganese formations scattered about on the sea bottom.
Manganese is already essential in steel production, but demand is also getting a substantial lift from the fast-growing electric vehicle market. The first company to find an economical way to harvest nodules from the ocean floor could reap a significant windfall.
Drill Baby, Drill
Demand for resources can force humans into some very inhospitable places, and in the case of Deepwater Horizon, we chased oil to a depth even surpassing the famed Marianas Trench.
Drilling that far below the surface is a complicated endeavor, and when the drill platform was put into service in 2001, it was hailed as an engineering marvel. To this day, Deepwater Horizon holds the record for the deepest offshore hole ever made.
After the rig’s infamous explosion and subsequent spill in 2010, that depth record for drilling may stand the test of time.
Ranked: The World’s Top 10 Automotive Exporters (2000-2022)
Data from the World Trade Organization highlights the world’s 10 largest automotive exporters in 2022.
Ranked: The World’s Top 10 Automotive Exporters
According to the European Automobile Manufacturers’ Association, over 85 million motor vehicles were built around the world in 2022.
In this graphic, we add context to this massive figure by ranking the world’s 10 largest automotive exporters. The list is based on data from the World Trade Organization (WTO) and includes countries from nearly every corner of the world, highlighting the global nature of the industry.
Top 10 Exporting Countries
The data we used to create this graphic is included in the table below. It represents each country’s share of the total export value of global automotive products in both 2000 and 2022.
“Automotive products” are defined by the WTO as motor vehicles, parts and accessories for motor vehicles, and internal combustion engines for propelling said vehicles. This grouping excludes motorcycles and trailers.

|🇰🇷 South Korea||2.6%||5.1%||+2.5|
From this list we can identify which countries have experienced the most growth or decline over the past 22 years.
Countries With the Most Growth Since 2000
The automotive exporters that grew their share of global value the most since 2000 are China (+7.7 pp), Mexico (+3.2 pp), and South Korea (+2.5 pp).
There are clear drivers behind each of these growth stories.
For example, China became the world’s largest car market back in 2009, which accelerated the growth of its domestic automakers. China is also home to some of the world’s biggest automotive suppliers, including Weichai (diesel engines), Hasco Automotive (drivetrain and air conditioning systems), and CATL (EV batteries).
Mexico, on the other hand, has grown its auto industry by enticing global brands to construct their factories there. The country’s competitive edge includes cheaper labor and a land border to the United States.
Finally there’s South Korea, whose growth is largely attributed to Hyundai Motor Company. The Seoul-based automaker recently became the third largest on a global basis, trailing only Toyota and Volkswagen.
Countries With the Biggest Decline Since 2000
The automotive exporters that declined the most since 2000 are Canada (-7.2 pp), Japan (-6.4 pp), and the U.S. (-2.6 pp).
Canada’s auto industry has experienced a steady decline in recent years, though new EV-related investments could turn things around. In March 2022, Stellantis and LG Energy Solutions announced the construction of a $3.5 billion EV battery plant in Windsor, Ontario.
Canada’s automotive industry is largely concentrated in the province of Ontario, which neighbors Michigan, the top state for U.S. car production.
