The NOAA Marine Debris Program created the Guide to MDMAP for Educators as a resource for educators who are interested in implementing MDMAP surveys with their students. The Guide provides instructions and tips for participating in MDMAP and planning, conducting, and following up on monitoring surveys with student groups. Understanding where, how much, and what kinds of debris are present in the marine environment is important to help combat the problem. This knowledge, along with an understanding of how the amount of marine debris on shorelines is changing over time, is essential to developing new and effective strategies for prevention, education, and outreach.
