A citizen science project that asks volunteers to transcribe historic ships’ logbooks to uncover data about past Arctic climate has added logbooks from hundreds of whaling ships. The hunters’ handwritten logs will provide new clues about the history of Arctic climate and sea ice.

A volunteer project enlists citizen scientists to transcribe climate observations buried in historic logbooks of U.S. ships that spent time in the Arctic.
