19. George Helffrich, Satoshi Kaneshima, Outer core compositional stratification, EGU, 2011.05, he liquid outer core of the earth is nearly pure iron, but contains light
elements that affect its density and seismic wavespeed. From the earliest
detailed studies of the outer core seismic structure, the topmost part of the
outer core appeared to differ from the core's main bulk. We report on a
detailed investigation of the structure of the topmost outer core. As other
workers did, we use differential SmKS-SnKS travel times and slownesses, with
path multiplicities (m,n) between 2 and 5. Unlike previous studies, we use
array measurements to obtain the travel time and slowness estimates. The
results, inverted with a tau-p method, yield a well constrained velocity
structure for the topmost 500 km of the outer core. The uppermost 300 km
is gradationally slower than the PREM model by up to 0.3%. Applying a
homogeneity test to the velocity profile shows that it differs significantly
at the 95% confidence level from compression of a simple liquid. Thus the
outer core is stratified in composition. The light element addition probably
arises from the growth of the inner core, and a rough material balance may be
made. Maintaining a 300 km thick layer against mixing by outer core convection
is problematic and suggests that the outermost core is stagnant..
