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).
Quality Assessment
Mean and Long-term drift has been removed from the data. Depths given are approximate.
| Period | Comments |
|---|---|
| Oct 1986 -Sep 1987 | Contributor recommends use of either pressure channel 1 or pressure channel 3. |
