Two bottom pressure recorders were deployed from April to August 1982 at 2.5°S, 95.0°W in 3751-m water depth and at 0.5°S, 89.5°W in water of 16-m depth to ascertain the background level of wave energy in the period range of 4-90 min. Preliminary analysis of these data reveals the instrument is capable of detecting: (1) tsunami as small as 1 cm in the open ocean and (2) disturbances from distant hurricanes.
