Table A.1: Coordinates of the stations of the Yellowknife Array. The stations named YKW are the 3 component broadband stations. At the location of YKW3 one three component broadband station and one three component, short period station with a high sample rate is located. All other stations are 1 component (vertical) short period stations.

Table A.2: Coordinates of the stations of the Tw~st Array in northern Ontario. Additionally, the splitting parameters by Kay et. al. (1999) are listed. $\Phi$ is the azimuth (in  $^{\circ}$) of the fast polarization and $\delta$t the delay time (in seconds) between fast and slow components. $\sigma _{\Phi}$ and $\sigma _{t}$ are the standard deviation from the weighted mean.

[Event list for YKA]List of all events which fulfill the criteria discussed in chapter 4.3. The events should be large and should show a short P coda and an impulsive PP onset. Shallower events are preferred because the depth phases of deep events show the equivalent travel times to P$^d$P. Nevertheless deep events are included to detect shallower discontinuities. The event relocations of Engdahl et al. (1998) are used.

[Results for shallow discontinuities (P$^{80}$P)]List of all events showing a P$^{80}$P precursor. The differential travel time $\Delta$t = t$_{PP}$ - t$_{P^{80}P}$ is listed. $\Delta$t is transformed into depth using ray tracing and the reference model IASP91 (Kennett and Engdahl, 1991). The estimated depth error due to picking errors and lateral inhomogeneities in the upper mantle is listed in the fourth column. The quality factor in the fifth column describes the quality (sharpness and amplitude) of the PP arrival on a scale from 1 (very good) to 4 (no visible PP arrival).
