The Bureau of Oceans and International Environmental and Scientific Affairs—often referred to as “Oceans, Environment, and Science” or simply “OES”—covers issues that reach from the vastness of space to the depths of the oceans.  Created by Congress in 1974, OES works to ensure economic growth and a healthy planet go hand in hand.

OES has a long and successful history of advancing U.S. interests in environment, science, technology, health, oceans, fisheries, and outer space to make sure American citizens and companies benefit from international opportunities in these sectors.  Whether combatting wildlife trafficking or helping to ensure the smooth functioning of Global Positioning System on smart phones, our issues hold a significant place in the American consciousness and in Americans’ daily lives.
