These posters were created for a contest intended to stir students’ interest in the ocean’s abyss. After attending an LSU Oceanography Department lecture, I decided to employ comparisons with everyday objects to accurately scale the extreme qualities of the ocean’s abyss (temperature, salinity, density, and darkness) from any other place on earth. My goal was to appeal to families with young children. These posters of the abyss were selected to be reproduced as classroom teaching aids.
