These data form part of the 'Tristan Triangle Experiment' around Tristan da Cunha which consisted of a series of Bottom Pressure Recorder measurements made in a 'triangle' (sites A, B and C) around the island between 1985-88 (Spencer et al.). Bottom pressure at all three sites was found to be coherent (Hughes and Smithson, 1996)
Mean and Long-term drift has been removed from the data. Depths given are approximate.
|Nov 1985 - Sep 1986||Contributor recommends use of either pressure
channel 1 or pressure channel 3.
|Oct 1986 - Sep 1987||Contributor recommend use of either prssure channel 2
or pressure channel 3.
Pressure channel 2 marked: (1986)294-(1987)100
Pressure channel 3 marked: (1986)294-297
