Overview

Atlantic Ocean at a glance

The Atlantic Ocean is the second largest of the world's five oceans (after the Pacific Ocean, but larger than the Indian Ocean, Southern Ocean, and Arctic Ocean). The Kiel Canal (Germany), Oresund (Denmark-Sweden), Bosporus (Turkey), Strait of Gibraltar (Morocco-Spain), and the Saint Lawrence Seaway (Canada-US) are important strategic access waterways. The decision by the International Hydrographic Organization in the spring of 2000 to delimit a fifth world ocean, the Southern Ocean, removed the portion of the Atlantic Ocean south of 60 degrees south latitude.

National Infrastructure

🏳 the Atlantic Ocean’s critical and strategic infrastructure, sustaining output, agility and endurance

The National Infrastructure Index maps the physical assets national life runs on — power stations and grids, water systems, ports, railways and airports, data networks, payment systems and launch sites. Each asset is placed in a Strategic Infrastructure capability group, so it can be read against the ratings in the National Capability index above.

Assets are chosen for how much of the economy and state depends on them and how hard they would be to replace. Each card records what the asset is, the category it belongs to, what it does and where it is.

Placeholder

Example assets. These twenty cards are modelled on China's most critical infrastructure and show on every nation page until each nation's own assets are mapped.

National Developments

🏳 the Atlantic Ocean’s major milestones and key developments

The National Development Index tracks the events that move a nation's capability — policy decisions, technological milestones, economic turns and external shocks — and places each one on the record with the date it happened and what followed from it. It is the narrative counterpart to the indices: where a rating says where the Atlantic Ocean stands, the index says how it arrived there.

Recent developments cover the current cycle, close enough that their consequences are still unfolding. Historical developments are the inflection points behind the present position — the decisions and events a reader needs in order to read the ratings above in context.

Historical Developments

19th–20th centuriesStrategic access waterways shaped Atlantic shipping about 130 years ago

The Kiel Canal in Germany, the Oresund between Denmark and Sweden, the Bosporus in Turkey, the Strait of Gibraltar between Morocco and Spain, and the Saint Lawrence Seaway between Canada and the US are important strategic access waterways, the engineered routes among them completed between 1895 and 1959.

2000The International Hydrographic Organization delimited the Southern Ocean, redrawing the Atlantic's boundary 26 years ago

The IHO's decision in the spring of 2000 to delimit a fifth world ocean removed the portion of the Atlantic Ocean south of 60 degrees south latitude. The Atlantic remains the second largest of the world's five oceans, after the Pacific but larger than the Indian, Southern and Arctic Oceans.

Economy - overview

The Atlantic Ocean provides some of the world's most heavily trafficked sea routes, between and within the Eastern and Western Hemispheres. Other economic activity includes the exploitation of natural resources, e.g., fishing, dredging of aragonite sands (The Bahamas), and production of crude oil and natural gas (Caribbean Sea, Gulf of Mexico, and North Sea).
