There are potential links between climate change in the Great Lakes and the deterioration of shipwrecks, but the topic remains under researched, and questions remain. For example, should climate change result in significantly decreased ice coverage on the Great Lakes, this would enhance evaporation and lead to a water level de­cline. As water levels drop, shallow water shipwrecks may become more exposed to air, waves and ice, thus accelerating natural decom­position. Nearshore shipwrecks in sandy lakebed environments may suffer increased deterioration as increasingly mobile sediment (due to a more dynamic environment created by lower water levels) vari­ously exposes and buries sites. Moreover, the sudden occurrence of a shallow-water shipwreck exposed by shifting sediment makes for an exciting discovery, but one that is also potentially very accessible, and can lead to both intentional and unintentional human impacts. The ef­fects of climate change on a delicately balanced and already stressed ecosystem could also have negative impacts by reducing water quality and, consequently, public accessibility to sanctuary resources. Climate change has also been identified as one of the most critical threats to Lake Huron’s biodiversity.
