About this video
New perspectives on old climate.
The National Maritime Museum 'Old Weather' project is collecting weather measurements from historic ship logs.
The crowd sourcing initiative enables anyone to log onto a website and begin transcribing scanned copies of the original hand-written logs. Locked away within these pages is a vast resource of climate data-sets. These records are dated and recorded at regular intervals from across the world's oceans, providing details such as temperature and air pressure.
This information is intensely useful to climate scientists: once recorded the data can be analysed to generate computer models of historic weather patterns, providing a valuable perspective on global climate.
Old Weather is part of the Zooniverse project, a citizen science network which relies on crowd sourced contributions to divide up resource intensive projects. Other projects include classifying whale sounds, identifying astronomical features from images and transcribing ancient texts.
This National Maritime Video video explains why making weather readings at sea is as important as those taken on land.
