Schimke, G.R. and Bufe, C.G. (1968). Geophysical description of a Pacific Ocean seamount. Journal of Geophysical Research 73(2): 559-569.

Intensive bathymetric, magnetic, and gravity data have been obtained over the previously uncharted Chatauqua seamount, 155 km west of Kauai, Hawaii. Detailed analyses of the data show that this seamount lies on the flank of the Hawaiian Ridge and is one member of a 230-km-long chain of seamounts oriented about 30 degrees from normal to the trend of the ridge. It rises with a slope of 15 degrees from 4,500 m to at least 1,785 m depth. Although the upper part is normally polarized, the bulk appears to be reversely polarized, the contrast in magnetic properties extending to about 1 km beneath the sea floor. The mean density of Chautauqua seamount is 2.5 g per cc. The gravity field shows evidence of block faulting during its development. The reversed magnetization could have been acquired during the Matuyama epoch or an earlier one.
