Bureau of Oceans and International Environmental and Scientific Affairs
Protecting Where We Live through Science, Innovation, and Partnership
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 advances U.S. strategic interests through policy aimed at ensuring that economic growth and a healthy planet go hand in hand.
Working on issues that impact millions of U.S. jobs and advance U.S. foreign policy and national security interests, OES builds international consensus around issues like fighting infectious diseases, and combatting wildlife trafficking and illegal, unregulated and unreported fishing. OES promotes water security, peaceful cooperation on polar issues, sustainable ocean policy, science and technology cooperation, nature conservation, and climate and space policy, among other vital topics.
OES is positioned at the center of the global conversation and serves at the forefront of U.S. diplomatic efforts to confront some of world’s greatest challenges.
Principal Deputy Assistant Secretary Marcia Bernicat currently leads OES.
