Which Countries are Mapping the Ocean Floor?
Our vast and complex planet is becoming less mysterious with each passing day.
Consider the following:
- Thousands of satellites are now observing every facet of our planet
- Around three-quarters of Earth’s land surface is now influenced by human activity
- Aircraft-based LIDAR mapping is creating new models of the physical world in staggering detail
But, despite all of these impressive advances, our collective knowledge of the ocean floor still has some surprising blind spots.
Today’s unique map from cartographer Andrew Douglas-Clifford (aka The Map Kiwi) focuses on ocean territory instead of land, highlighting the vast areas of the ocean floor that remain unmapped. Which countries are exploring their offshore territory, and how much of the ocean floor still remains a mystery to us? Let’s dive in.
What Do We Know Right Now?
Today, we have a surprisingly incomplete picture of what lies beneath the waves. In fact, if you were to fly from Los Angeles to Sydney, the bulk of your journey would take place over territory that is mapped in only the broadest sense.
Most of what we know about the ocean floor’s topography was pieced together from gravity data gathered by satellites. While useful as a starting point, the resulting spatial resolution is about two square miles (5km). By comparison, topographic maps of Mars and Venus have a resolution that’s 50x more detailed.
As the map above clearly illustrates, only a few large pieces of the ocean have been mapped—and not surprisingly, many of these higher resolution portions lie along the world’s shipping lanes.
Another way to see this clear difference in resolution is through Google Maps:
As you can see above, these shipping lanes running through the Pacific Ocean have been mapped at a higher resolution that the surrounding ocean floor.
The Countries Mapping the Ocean Floor
The closer an area is to a population center, the higher the likelihood it has been mapped. That said, many countries still have a long way to go before they have a clear picture of their land beneath the waves.
Here is a snapshot of how far along countries are in their subsea mapping efforts:
|Countries/territories||Size of Exclusive Economic Zone* (EEZ)||Percentage of EEZ mapped|
|Japan||1,729,501 mi² (4,479,388 km²)||97.7%|
|United Kingdom||2,627,651 mi² (6,805,586 km²)||90.6%|
|Norway||920,922 mi² (2,385,178 km²)||81.9%|
|New Zealand||1,576,742 mi² (4,083,744 km²)||74.0%|
|United States||4,382,645 mi² (11,351,000 km²)||69.9%|
|Australia||3,283,933 mi² (8,505,348 km²)||64.9%|
|Iceland||291,121 mi² (754,000 km²)||49.9%|
|South Africa||592,874 mi² (1,535,538 km²)||39.5%|
|Canada||2,161,815 mi² (5,599,077 km²)||38.8%|
|Samoa||49,401 mi² (127,950 km²)||34.6%|
|South Korea||183,579 mi² (475,469 km²)||28.3%|
|Taiwan||32,135 mi² (83,231 km²)||26.3%|
|Argentina||447,516 mi² (1,159,063 km²)||22.6%|
|Cook Islands||756,770 mi² (1,960,027 km²)||29.0%|
|Phillippines||614,203 mi² (1,590,780 km²)||16.7%|
|China||338,618 mi² (877,019 km²)||11.4%|
|Madagascar||473,075 mi² (1,225,259 km²)||5.5%|
|Bangladesh||45,873 mi² (118,813 km²)||3.3%|
|Thailand||115,597 mi² (299,397 km²)||1.5%|
*An exclusive economic zone (EEZ) is the sea zone stretching 200 nautical miles (nmi) from the coast of a state.
Japan and the UK, which have the 5th and 8th largest EEZs respectively, are the clear leaders in mapping their ocean territory.
Piecing Together the Puzzle
Sometimes tragedy can have a silver lining. By the time the search for Malaysia Airlines Flight 370 concluded in 2014, scientists had gained access to more than 100,000 square miles of newly mapped sections of the Indian Ocean.
Of course, it will take a more systematic approach and sustained effort to truly map the world’s ocean floors. Thankfully, a project called Seabed 2030 has the ambitious goal of mapping the entire ocean floor by 2030. The organization is collaborating with existing mapping initiatives in various regions to compile bathymetric information (undersea map data).
It’s been said without hyperbole that we know more about the surface of Mars than we do about our own planet’s seabed, but thanks to the efforts of Seabed 2030 and other initiatives around the world, puzzle pieces are finally falling into place.
Visualizing the Power Consumption of Bitcoin Mining
Bitcoin mining requires significant amounts of energy, but what does this consumption look like when compared to countries and companies?
Visualizing the Power Consumption of Bitcoin Mining
Cryptocurrencies have been some of the most talked-about assets in recent months, with bitcoin and ether prices reaching record highs. These gains were driven by a flurry of announcements, including increased adoption by businesses and institutions.
Lesser known, however, is just how much electricity is required to power the Bitcoin network. To put this into perspective, we’ve used data from the University of Cambridge’s Bitcoin Electricity Consumption Index (CBECI) to compare Bitcoin’s power consumption with a variety of countries and companies.
Why Does Bitcoin Mining Require So Much Power?
When people mine bitcoins, what they’re really doing is updating the ledger of Bitcoin transactions, also known as the blockchain. This requires them to solve numerical puzzles which have a 64-digit hexadecimal solution known as a hash.
Miners may be rewarded with bitcoins, but only if they arrive at the solution before others. It is for this reason that Bitcoin mining facilities—warehouses filled with computers—have been popping up around the world.
These facilities enable miners to scale up their hashrate, also known as the number of hashes produced each second. A higher hashrate requires greater amounts of electricity, and in some cases can even overload local infrastructure.
Putting Bitcoin’s Power Consumption Into Perspective
On March 18, 2021, the annual power consumption of the Bitcoin network was estimated to be 129 terawatt-hours (TWh). Here’s how this number compares to a selection of countries, companies, and more.
|Name||Population||Annual Electricity Consumption (TWh)|
|All of the world’s data centers||-||205|
|State of New York||19.3M||161|
|Walt Disney World Resort (Florida)||-||1|
Note: A terawatt hour (TWh) is a measure of electricity that represents 1 trillion watts sustained for one hour.

If Bitcoin were a country, it would rank 29th out of a theoretical 196, narrowly exceeding Norway’s consumption of 124 TWh. When compared to larger countries like the U.S. (3,989 TWh) and China (6,543 TWh), the cryptocurrency’s energy consumption is relatively light.
For further comparison, the Bitcoin network consumes 1,708% more electricity than Google, but 39% less than all of the world’s data centers—together, these represent over 2 trillion gigabytes of storage.
Where Does This Energy Come From?
In a 2020 report by the University of Cambridge, researchers found that 76% of cryptominers rely on some degree of renewable energy to power their operations. There’s still room for improvement, though, as renewables account for just 39% of cryptomining’s total energy consumption.
Here’s the share of cryptominers that use each energy type vary across four global regions.

and the Caribbean

Editor’s note: Numbers in each column are not meant to add to 100%
Hydroelectric energy is the most common source globally, and it gets used by at least 60% of cryptominers across all four regions. Other types of clean energy such as wind and solar appear to be less popular.
Coal energy plays a significant role in the Asia-Pacific region, and was the only source to match hydroelectricity in terms of usage. This can be largely attributed to China, which is currently the world’s largest consumer of coal.
Researchers from the University of Cambridge noted that they weren’t surprised by these findings, as the Chinese government’s strategy to ensure energy self-sufficiency has led to an oversupply of both hydroelectric and coal power plants.
Towards a Greener Crypto Future
As cryptocurrencies move further into the mainstream, it’s likely that governments and other regulators will turn their attention to the industry’s carbon footprint. This isn’t necessarily a bad thing, however.
Mike Colyer, CEO of Foundry, a blockchain financing provider, believes that cryptomining can support the global transition to renewable energy. More specifically, he believes that clustering cryptomining facilities near renewable energy projects can mitigate a common issue: an oversupply of electricity.
“It allows for a faster payback on solar projects or wind projects… because they would [otherwise] produce too much energy for the grid in that area”
– Mike Colyer, CEO, Foundry
This type of thinking appears to be taking hold in China as well. In April 2020, Ya’an, a city located in China’s Sichuan province, issued a public guidance encouraging blockchain firms to take advantage of its excess hydroelectricity.
UN Sustainable Development Goals: How Companies Stack Up
Are companies making progress in meeting the UN Sustainable Development Goals? This tracker shows how companies are measuring up.
The UN SDGs: How Companies Stack Up
Environmental, social, and governance (ESG) investing witnessed a breakthrough year in 2020 with the most fund inflows on record.
Importantly, for companies that are judged according to ESG metrics, one way to track their progress is through their alignment to the UN Sustainable Development Goals (SDGs).
Established in 2012, the UN SDGs are a blueprint for creating a more sustainable future by 2030 that have been adopted by 193 countries worldwide.
As investors and stakeholders pay closer attention to sustainability concerns, this graphic from MSCI breaks down how companies stack up according to their alignment to the UN SDGs.
How Were Companies Measured?
To track companies net contribution to the UN SDGs, companies were scored by their positive or negative contribution to each of the 17 goals.
The 17 UN SDGs are designed to achieve three primary objectives by 2030:
- Protect the planet
- End poverty
- Create prosperity and peace for all
Specifically, the framework centers on a discussion paper that was developed in partnership with the OECD in 2018. Company policies, operations, products and services, and practices are analyzed according to reported and publicly available information.
Tracking the Alignment of Companies
Across a universe of 8,550 companies in the MSCI All Country World Index, constituents were measured from strongly aligned to strongly misaligned to the UN SDGs.
|3||Good Health and Well-being||0||315||141||29|
|6||Clean Water and Sanitation||17||325||36||10|
|7||Affordable and Clean Energy||43||639||109||587|
|8||Decent Work and Economic Growth||25||1269||52||17|
|9||Industry, Innovation, and Infrastructure||68||844||137||9|
|11||Sustainable Cities and Communities||0||0||167||19|
|12||Responsible Consumption and Production||115||855||150||598|
|14||Life Below Water||0||36||151||92|
|15||Life on Land||0||0||128||17|
|16||Peace and Justice Strong Institutions||0||135||241||27|
|17||Partnerships to Achieve the Goal||0||401||152||22|

Broadly speaking, companies fell mostly in the middle—roughly 38% were aligned while almost 55% were misaligned or neutral. Meanwhile, just 0.2% of companies were strongly aligned to the UN SDGs.
Overall, one of the most strongly aligned goals was Responsible Production and Consumption, with 115 companies meeting this criteria. Specifically, these include companies that are building sustainable infrastructure, energy efficiency, or creating green jobs.
Interestingly, the worst performing goal was also Responsible Production and Consumption, with over five times as many companies (598) strongly misaligned. Along with this goal, both Climate Action and Affordable and Clean Energy each had over 500 companies strongly misaligned.
UN SDGs: A Sector Focus
Unsurprisingly, SDG-alignment varied widely according to company sectors.
Educational companies, for instance, represented the highest level of alignment to Gender Equality. Meanwhile, 18% of 425 utilities companies assessed ended up aligning with Clean and Affordable Energy goals.
As one would expect, the energy sector lagged behind. In 2020, fossil fuels were a key source of revenue for 91% of the companies in the energy business. In fact, just three companies derived over 50% of their revenues from green alternatives: REX American Resources, Renewable Energy Group, and Verbio.
A Call to Action?
Despite the growing wave of interest in ESG investing, the reality is that progress to meet the UN SDGs has been slower going than expected.
However, a greater number of individuals, stakeholders, and activists are sounding the alarm. Today, over 3,000 signatories representing trillions in assets under management have committed to the UN Principles of Responsible Investment, which has established six key actions for ESG investing. Now, many companies are required to report their ESG disclosures in Europe.
Along with these key markers of progress, investors can move the dial by tracking a company’s alignment to sustainable development goals.
