• Provides leadership and research in marine, estuarine, and watershed ecology and ecotoxicology to predict and assess the effects of human-generated stressors on the aquatic resources of the U.S. Gulf of Mexico and the U.S.;
• Uses its research to help determine ecological condition, evaluate rates and causes of declining systems, and predict future conditions under various alternative water quality scenarios; and
• Works closely with communities, states, and the region to develop tools and provide a scientific basis for sustainable environmental management decisions that maximize economic, ecosystem, and social outcomes and resiliency.
