Old Weather volunteers explore, mark, and transcribe historic ship's logs from the 19th and early 20th centuries. We need your help because this task is impossible for computers, due to diverse and idiosyncratic handwriting that only human beings can read and understand effectively. By participating in Old Weather you'll be helping advance research in multiple fields. Data about past weather and sea-ice conditions are vital for climate scientists, while historians value knowing about the course of a voyage and the events that transpired. Since many of these logs haven't been examined since they were originally filled in by a mariner long ago you might even discover something surprising.
