Physical properties were measured on 98 basalt samples obtained during Leg 55. These basalts can be taken as typically representative of the upper parts of the seamounts in the Emperor Seamount chain. Variations in the measured physical properties among the samples result from their water content or porosity. The variations and the intrinsic (pore-free) properties of the seamount basalts are comparable to those of normal sea-floor basalts. The higher average porosity value and the wider dispersion of porosity data for the seamount basalts, reflecting their subaerially erupted origin, result in smaller average physical properties values for these basalts compared with sea-floor basalts.
