The word "transatlantic" says it: it was the trade across the Atlantic ocean from Africa to the Americas.
The Portuguese focused on establishing trade routes to Asia, while the Spanish focused on colonizing the Americas. The Portuguese reached India by sailing around Africa, while the Spanish reached the Americas by sailing west across the Atlantic.
The Atlantic trade route mainly involved the continents of Europe, Africa, and the Americas. Europe used trading posts in Africa to acquire slaves and goods, which were then transported across the Atlantic to the Americas for sale or exchange.

The Middle Passage was the section of the trade routes from the fifteenth through eighteenth centuries in which African peoples were transported across the Atlantic Ocean to the Americas. While many of the Africans died, the numbers are estimated at close to 2 million rather than one billion.
Christopher Columbus's life-long dream was to find a new and faster trade route to Asia by sailing west across the Atlantic Ocean. In 1492, he made this dream a reality when he reached the Americas instead, leading to the exploration and colonization of the New World.
