Describe how science, technology, and knowledge aided in transoceanic travel and trade

Science, technology, and knowledge aided in transoceanic travel by allowing for safer travel to take place. When advances in cartography began to spike, travel was allowed to have a purpose. Travelers didn't have to hope that they were going the right way, or have to wonder if the land that they had reached was where they wanted to go. Maps were able to help travelers to easily navigate their way to lands where they could make trades and profit.
