Tsunami Debris Monitoring

Marine debris is an every-day problem for much of the Pacific area, so in most cases it is difficult to tell whether an item was lost during the tsunami. However, significant changes in the types and quantities of debris at a shoreline over time may be a sign that tsunami debris is washing ashore. To observe a potential shift in debris types and abundance, many NOAA partners and volunteers throughout the five impacted states are conducting monthly shoreline surveys for at least two years.

The initiative is part of the Marine Debris Monitoring and Assessment Project (MDMAP), a larger NOAA Marine Debris Program effort to learn more about the types and quantities of debris on our shorelines. View a map of shoreline monitoring sites or request access to MDMAP data here.
