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.

Mariana trench depth compared to cities

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.

Polymetallic Nodules

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.

10 Travel Destinations for Post-Pandemic Life

On March 11, 2020, the World Health Organization formally classified the COVID-19 outbreak as a pandemic. The resulting travel bans decimated the tourism industry, and international air travel initially fell by as much as 98%.

Almost two years later, travel is finally back on the table, though there are many restrictions to consider. Regardless, a survey conducted in September 2021 found that, as things revert to normalcy, 82% of Americans are looking forward to international travel more than anything else.

To give inspiration for your next vacation (whenever that may be), this infographic lists the 10 most visited countries in 2019, as well as three of their top attractions according to Google Maps.

Bon Voyage

Here were the 10 most popular travel destinations in 2019, measured by their number of international arrivals.

CountryNumber of international arrivals in 2019 (millions)
🇫🇷 France*90.0
🇪🇸 Spain83.5
🇺🇸 U.S.79.3
🇨🇳 China65.7
🇮🇹 Italy64.5
🇹🇷 Turkey51.2
🇲🇽 Mexico45.0
🇹🇭 Thailand39.8
🇩🇪 Germany39.6
🇬🇧 United Kingdom39.4

France was the most popular travel destination by a significant margin, and it’s easy to see why. The country is home to many of the world’s most renowned sights, including the Arc de Triomphe and Louvre Museum.

The Arc de Triomphe was built in the early 1800s, and honors those who died in the French Revolutionary and Napoleonic Wars. In 1944, Allied soldiers marched through the monument after Paris was liberated from the Nazis.

The Louvre Museum, on the other hand, is often recognized by its giant glass pyramid. The museum houses over 480,000 works of art, including Leonardo da Vinci’s Mona Lisa.

Art isn’t the only thing that France has to offer. The country has a reputation for culinary excellence, and is home to 632 Michelin-starred restaurants, the most out of any country. Japan comes in at second, with 413.

While You’re There…

After seeing the sights in Paris, you may want to consider a visit to Spain. The country is the southern neighbor of France and is known for its beautiful villages and beaches.

One of its most impressive sights is the Sagrada Familia, a massive 440,000 square feet church which began construction in 1882, and is still being worked on today (139 years in the making). The video below shows the structure’s striking evolution.

At a height of 172 meters, the Sagrada Familia is approximately 52 stories tall.

Another popular spot is Ibiza, an island off the coast of Spain that is famous for its robust nightlife scene. The island is frequently mentioned in pop culture—Netflix released an adventure/romance movie titled Ibiza in 2018, and the remix of Mike Posner’s song I Took a Pill in Ibiza has over 1.4 billion views on YouTube.

Beaches Galore

If you’re looking for something outside of Europe, consider Mexico or Thailand, which are the 7th and 8th most popular travel destinations. Both offer hot weather and an abundance of white sand beaches.

Expect Turbulence

Under normal circumstances, hundreds of billions of dollars are spent each year by international tourists. According to the World Travel & Tourism Council (WTCC), this spending accounted for an impressive 10.4% of global GDP in 2019.

Travel restrictions introduced in 2020 dealt a serious blow to the industry, reducing its share of global GDP to 5.5%, and wiping out an estimated 62 million jobs. While the WTCC believes these jobs could return by 2022, the emerging Omicron variant has already prompted many countries to tighten restrictions once again.

To avoid headaches in the future, make sure you fully understand the rules and restrictions of where you’re heading.

Which Values Children Should Be Encouraged to Learn, By Country

Which qualities do people think are most important for children to learn? The answer differs from country to country.

Published

on

Qualities Children Should Learn

Many of the values we prioritize as adults were instilled in us during our childhood days.

They’re called our formative years for a reason—from when we’re born up until we’re about eight years old, our brains are easily molded and remain highly sensitive to external influences and environments. But depending on where you grew up, you may have been exposed to different values during your childhood compared to someone from another place.

These visualizations by Anders Sundell illustrate the most important values people think children should learn at home, across more than 80 different countries.

Methodology

Sundell used data from the World Values Survey, an international survey that interviews hundreds of thousands of participants from across the globe. Respondents were asked to pick up to five qualities they believe are the most desirable for children to have:

  • Good manners
  • Independence
  • Hard work
  • Feeling of responsibility
  • Imagination
  • Tolerance and respect for other people
  • Thrift, saving money
  • Determination and perseverance
  • Religious faith
  • Unselfishness
  • Obedience

Sundell took the survey data and calculated the proportion of people in each country that selected each quality. From there, he took the top qualities and created three separate plot graphs to show the contrast between them.

Let’s look at the importance that countries placed on different values, including (1) independence and obedience, (2) unselfishness and religious faith, and (3) hard work and imagination.

1. Independence vs Obedience

Nordic countries value independence greatly, and find obedience to be a less important quality to instill in children.

Other available data also supports that adults in Nordic countries value independence. According to Eurostat, the most common age to leave home in Sweden is between 17 and 18—nearly a decade sooner than the average age across the EU (26 years old).

Denmark’s average age to leave home is also below the European average, at 21 years old.

On the other end of the spectrum, countries like Iraq and Egypt believe obedience is much more important for children to learn.

2. Unselfishness vs Religious Faith

Bangladesh, Egypt, and Jordan all place a strong emphasis on faith, and fall on the far right of this graph.

Islam is a strong influence in all three of these countries. In Bangladesh and Jordan, it’s the official state religion. And while Egypt is a secular country, a majority of citizens identify as Muslim—about 90% of the population.

Interestingly, places like the U.S. and Hong Kong fall right in the between, placing relatively equal importance on religion and unselfishness.

3. Hard Work vs Imagination

Left-leaning Nordic countries like Sweden, Norway, Denmark, and Finland think imagination is more important for children to learn than hard work.

Interestingly, Japan also scored high for imagination, seeing it was a more important value to teach children than hard work. This is despite the fact that the country has an international reputation for being a hardworking country, where even taking an extended vacation can be frowned upon. Then again, Japan has a reputation for producing wildly creative works of art that are popular internationally (anime, for instance).

As expected, countries and cultures contain multitudes, and can often seem paradoxical and complex to those who try to codify them.

What qualities do you think are most important, and what countries surprised you with their placements?
