http://www.oldweather.org takes
you back into the past - we have World War I ship's logs from 280
Royal Naval vessels for you to explore. Whether in battle, in port or
on patrol, the ship's crew recorded information about the weather.
That information is critical for climate scientists trying to improve
their computer models. As well as rescuing those weather observations,
we're also asking you to record the personal and political events
aboard the ship. It's great fun and highly addictive: you have been
warned!"
