Governors Island Water Data 1851 (image) American Geophysical Union Caption This notebook shows water level data for Governors Island in New York in 1851. Before 1853, water level data was directly tabulated into notebooks like this one by tidal observers. Authors of a new study used this handwritten data to investigate storm tide levels for New York harbor back to 1844.
