COLLABORATIVE MOMA PROJECTSShear-Wave Splitting Beneath MOMA Shear wave splitting measurements were taken at MOMA and other eastern North American stations to examine the continental keel and patterns of mantle flow. [Fouch et al., 2000] For related work, go to Matt Fouch's Web Page. __________________________________________________________________________Anisotropy at the Base of the Mantle from SHdiff/SVdiff Waves  Differences bewteen the SHdiff and SVdiff waves observed at MOMA stations are used to examine the horizontal and vertical anisotropic variations in the D'' layer beneath the mid-Pacific. [Fouch et al., 2001] [Fouch et al., 2002] __________________________________________________________________________Using SPdiffKS Waves to Examine the D'' ULVZ For related work, go to Karen Fischer's Web Page. __________________________________________________________________________Crustal Thickness Variations Across MOMA Receiver functions are used to examine the lateral variation of the crust across the MOMA array. [Li et al., 2002] For related work, go to Aibing Li's Web Page. __________________________________________________________________________Mantle Discontinuity Depth Variations Beneath MOMA Converted phases are used to map out the change in mantle discontinuity topography in relation to the location of the Farallon slab.
