Notes: Inclination of characteristic remanent magnetization was determined by principal component analysis. T = thermal, A = alternating field. N = number of measurements used for principal component analysis. MAD = maximum angle of deviation (Kirshvink, 1980). Lava flows are from Shipboard Scientific Party, 2001. * = colatitude not used in paleolatitude calculations. † = principal component analysis used anchor point at origin. — = not applicable.
