Tide gauge

Accession no.: N: 781
Object name: Tide gauge
Title: Tide gauge
Description: A wood box containing an in-built automatic tide gauge used on the British Graham Land Expedition 1934-37 (Penola). The gauge was designed for use when the sea was frozen and would stand on a small table on the sea ice. A flexible wire was fixed to the bottom of the sea and passed over the pulley to a counterpoise weight which kept the wire tight. The up and down movement of the ice with the tide, and therefore of the gauge, was communicated to the pulley and ultimately operated a pen.
