Marine debris is unfortunately an all too frequent sight on our coastlines. A common misconception is that all shoreline debris was left behind by beachgoers. In fact, debris makes its was to the beach from many different sources, including the sea, stormwater runnoff, wind, and nearby river or stream outlets. If you spend time exploring shorelines in different regions, you may notice that the types and amounts of debris are different from place to place (and constantly changing!).
