Figure 10. Buchanan mercury piezometer - the second type of piezometer made by John Buchanan during the CHALLENGER Expedition. Like the preceding model, this type had thermometers which remained open to the hydrostatic pressure of the sea at the depth deployed. Buchanan credited Aime with this idea and used this instrument to study the compressibility of mercury.
