The discovery of Sir John Franklin's ship HMS Terror this week, along with HMS Erebus two years ago, provide valuable tools to unlocking the mystery of the doomed 1845 expedition. Thanks to the cold, clear Arctic waters, both ships have been preserved in remarkable condition, especially the Terror. In fact, the preservation is so good, archaeologists expect to find artifacts inside as detailed as written documents still lying in drawers. Measures must be taken to ensure this doesn't happen with the wrecks of the Franklin expedition. The harsh Arctic environment has preserved the Franklin ships from more than a century and a half.
