Below are links to two resources designed to engage broad audiences and help explorers of all ages to investigate and better understand the tools, techniques, and importance of marine archaeology.
This theme page provides links to content essays, lessons, multimedia interactive activities, career information, and associated past expeditions related to underwater archaeology.
Underwater archaeological excavation is very similar to traditional land archaeology. The most common (and perhaps most popular) type of sites studied are shipwrecks. However, marine archaeologists also investigate other kinds of sites, such as flooded land sites or fishing structures.
From August 16 to 27, 2010, a team of explorers set out to discover new shipwrecks sites within Thunder Bay National Marine Sanctuary using cutting-edge sonar mounted on a free-swimming autonomous underwater vehicle. Learn more about the expedition and access expedition-specific education materials.
