Limnology and Oceanography Defined

Aquatic science is the study of the planet's oceanic and freshwater environments. Oceanography is the study of the biological, chemical, geological, optical and physical characteristics of oceans and estuaries, while limnology is the study of these same characteristics in inland waters (lakes, rivers, streams, ponds, and wetlands).

Educational Resources

If you are an instructor or teaching assistant preparing for a course in oceanography, limnology, or general earth science, ASLO may be able to help. We have an extensive collection of free access, peer-reviewed, and up-to-date content that can be a perfect supplement to your course material.
