2 Core-mantle boundary (CMB) Stoneley mode repreent a unique cla of normal mode with extremely trong enitivity to wave peed and denity variation in the D region. We meaure plitting function of 8 CMB Stoneley mode uing modal pectra from 93 event with M w > 7.4 between The obtained plitting function map correlate well with the predicted plitting calculated for S20RTS+Crut5.1 tructure and the ditribution of S diff and P diff travel time anomalie, uggeting that they are robut. We illutrate how our new CMB Stoneley mode plitting function can be ued to etimate denity variation in the Earth lowermot mantle.
3 1. Introduction The D region i the lowet km of the mantle, atop the core-mantle boundary (CMB). D i characterized by ultra-low-velocity zone (ULVZ), eimic dicontinuitie, aniotropy, CMB topography, and, mot prominently, by large-low-hear-velocity province (LLSVP) below Africa and the Pacific [e.g. Lay, 2007; Garnero and McNamara, 2008]. The LLSVP extend hundred of kilometer both laterally and vertically into the lower mantle [Ritema et al., 1999]. To ae their effect on mantle dynamic it i eential to have information on the denity variation [Forte and Mitrovica, 2001]. Obervation of Earth normal mode have the potential to contrain both wave peed and denity variation in the mantle. Previou normal mode analye ugget an anticorrelation between variation in the eimic hear velocity and denity, particularly for the LLSVP [e.g. Ihii and Tromp, 1999; Trampert et al., 2004; Moca et al., 2012]. Thee reult motivated the modeling of LLSVP a long-lived pile of intrinically dene material [e.g. Davaille, 1999; McNamara and Zhong, 2005]. However, it wa debated whether ome of thee denity model are robut a they depend on the regularization and a priori contraint [Romanowicz, 2001; Kuo and Romanowicz, 2002] and the tudied mode have enitivity to both the upper and lower mantle [Reovky and Ritzwoller, 1999]. Here we reviit normal mode contraint on the denity tructure of the lower mantle by focuing on Stoneley mode [Stoneley, 1924]; a unique cla of mode that are confined to olid-liquid interface uch a the CMB (Figure ). CMB Stoneley mode have extremely focued enitivity to tructure in D and the outermot core and hence do not uffer from trade-off with upper mantle tructure. However, they have o far not been oberved due to
4 inufficient available data. We preent, for the firt time, plitting function meaurement of CMB Stoneley mode, dicu the robutne of our meaurement, and illutrate how they can be ued in tomographic inverion to contrain denity tructure in the lowermot mantle. 2. Normal mode Earth normal mode are tanding wave ariing along the urface and radiu of the Earth. They are oberved a clear peak in the amplitude pectra of everal day long eimic recording of large (M w > 7.4) earthquake. Mode only exit at dicrete frequencie, due to the finite ize of the Earth, and are characterized by their radial order n and angular order l. We focu here on pheroidal mode n S l which involve P-SV motion. Each normal mode conit of 2l+1 inglet with azimuthal order m in the range l,...,l. Thee inglet are degenerate (i.e. have the ame frequency) for a pherically ymmetric, iotropic, non-rotating Earth model uch a the Preliminary Reference Earth Model (PREM) [Dziewonki and Anderon, 1981]. Significant plitting of the inglet into different frequencie occur by the rotation and ellipticity of the Earth and velocity and denity heterogeneity, aniotropy and topography on internal boundarie in the Earth. Normal mode plitting can be completely decribed uing the plitting function approach introduced by Woodhoue and Giardini [1985]. Splitting function coefficient c t are linearly related to the perturbation of the reference Earth model according to: c t = a 0 δm t (r) K (r) dr + d δh d th d (1) where δm t (r) are the pherical harmonic coefficient of angular order and azimuthal order t to decribe Earth tructure, including perturbation in S-wave velocity (V ), P-wave
5 velocity (V p ), denity (ρ) and aniotropy. δh d t repreent topography on dicontinuitie d and K (r), H d are the aociated enitivity kernel [Woodhoue, 1980]. Splitting function map F (θ, ϕ) are ued to viualize plitting function, i.e., F (θ, ϕ) = 2l =0 t= c t Y t (θ, ϕ) (2) where Y t (θ, ϕ) are the complex pherical harmonic of Edmond [1960]. Thee map how the local variation in plitting due to the underlying heterogeneity. 3. Method and data Splitting function are meaured from the inverion of pectra oberved for large earthquake. We make ue of a recent normal mode pectra data et of 92 event with M w > 7.4 for the period [Deu et al., 2011, 2013], with the addition of the 2011 Tohoku event (M w = 9.0). Following Deu et al. [2013] we meaure the plitting function uing non-linear iterative leat quare inverion [Tarantola and Valette, 1982], tarting from PREM or prediction for mantle and crut tructure. Cro validation i ued to determine the error of our meaured coefficient. Meauring CMB Stoneley mode i complicated a they generally overlap in frequency with a (high-amplitude) fundamental mode with n = 0. Hence, we mut invert for their plitting function jointly a previouly done for 1 S 14 by Reovky and Ritzwoller [1998]. We alo meaure the fundamental mode eparately to verify that we improve the mifit by including the CMB Stoneley mode. We account for the coupling between fundamental pheroidal and toroidal mode due to Earth ellipticity and rotation. The mifit i maller when the CMB Stoneley mode i added (Table 1), which i alo viible for individual pectra (Figure ).
6 We compare our meaurement to prediction for mantle and crut tructure, calculated uing mantle V model S20RTS [Ritema et al., 1999]. We aume caling factor of the form R p = δlnv p /δlnv = 0.5 and R ρ = δlnρ/δlnv = 0.3, conitent with previou work [Karato, 1993; Li et al., 1991]. The contribution of crutal thickne, urface topography and water level are calculated uing model Crut5.1 [Mooney et al., 1998]. 4. Reult 4.1. Splitting function obervation We have made plitting function meaurement of 23 mode in total, including 8 CMB Stoneley mode and 4 other new mode along the ame overtone branche ( 1 S 15, 1 S 16, 2S 14 and 3 S 25 ). In addition, we have meaured the aociated fundamental mode up to 0S 26. The oberved plitting function map (Figure ) how the Ring around the Pacific pattern of high frequencie and pronounced low frequencie at the LLSVP. Within the Ring tructure, iolated patche of elevated frequencie are identified, particularly underneath Southeatern Aia and South America. The plitting function map reemble the prediction for S20RTS+Crut5.1 tructure cloely. However, individual coefficient uch a the c 20 differ ubtantially from the prediction (ee Figure S1). In addition, the mifit i ignificantly lower for our meaurement (Table 1). We verify uing F-tet tatitic that the mifit reduction due to including the CMB Stoneley mode i ignificant (90 % confidence level). Detail on the mifit calculation and F-tet can be found in the upplementary online material. Correponding center frequencie and quality factor for
7 our meaurement are in Table 2 and our plitting function coefficient can be found online (Table S1) Comparion to S diff and P diff data CMB Stoneley mode have imilar enitivity to wave diffracting around the core uch a the S diff and P diff phae. We ue the travel time anomaly data et from Ritema and Van Heijt [2002] obtained for event between 1980 and 2000 with M b > 5.9. The binned data how good coverage in the Northern hemiphere but le in the Southern hemiphere (Figure a-c). Again, we oberve a characteritic Ring around the Pacific pattern, becoming even clearer in the even pherical harmonic expanion of the diffracted wave data (Figure b-d), though, ome of the outhern hemiphere tructure could be due to inherent ymmetry of the even degree expanion. The expanded S diff and P diff data and the CMB Stoneley mode plitting function of 2S 25 and 3 S 26 have a trong reemblance. The correlation between the mode and S diff data i typically 0.99 and 0.75 for degree 2 and 4 repectively wherea the correlation to P diff data i lower at 0.98 and Thi imilarity trengthen our confidence in our CMB Stoneley mode meaurement. The additional advantage of the normal mode i that they automatically provide coverage in the Southern hemiphere Senitivity to denity The enitivity kernel of the CMB Stoneley mode (Figure ) how a trong enitivity to V p at the CMB wherea the enitivity to V and ρ i imilar and peak in the D above the CMB. Thu, Stoneley mode are ueful to contrain R ρ in the D which play an important role in determining the nature of the LLSVP. We calculate plitting function
8 ynthetic uing S20RTS and Crut5.1 in which we vary R p and R ρ between -1 and 2 for a 300 km thick D layer. We compute the mifit between the oberved and calculated plitting function coefficient for individual mode. Contour plot of the mifit for = 2 are hown for mode 1 S 10 (previouly oberved e.g. Reovky and Ritzwoller [1998]; Deu et al. [2013]) and CMB Stoneley mode 3 S 26 (Figure ). 1 S 10 can be ued to put ome contraint on R P but cannot contrain denity variation even though the enitivity in D i non-zero. However, 3 S 26 ha a trong enitivity to both R P and R ρ, and the ame i oberved for other CMB Stoneley mode. Auming value for R P of 0.5 and 0.25 a a range of poible value [Karato, 1993; Ritema and Van Heijt, 2002], we oberve for 3 S 26 a bet fitting R ρ of 0.1 and 0.5 repectively, cloe to the range of ratio that would be conitent with purely thermal variation [e.g. Karato, 1993; Moca et al., 2012]. Thi ugget that the anti-correlation between denity and hear wave velocity might not be required by our new data. However, without good contraint on R P we cannot contrain R ρ accurately. In addition, R P and R ρ trade-off with other tructure in D uch a CMB topography and ULVZ [Koelemeijer et al., 2012], and therefore a proper inverion i required to draw any firm concluion regarding thermal veru thermochemical LLSVP. 5. Concluding remark Uing a data et of 93 large earthquake we make robut plitting function obervation of 8 CMB Stoneley mode. Their plitting function map correlate well with expanded S diff and P diff data uggeting they are robut. We demontrate the enitivity of the Stoneley mode to denity variation in the lowermot mantle and illutrate the trade-off
9 with P-wave velocity tructure. Thi trade-off can be partially removed when we conider thinner layer (100 km thick) due to the nature of the enitivity kernel (Figure ). In addition, a large number of P-wave enitive normal mode obervation i available [Deu et al., 2013] and body wave data alo provide contraint on R P. Therefore, when our new meaurement are included with thee in tomographic inverion they will help to provide tighter contraint on the denity variation in the lowermot mantle. Acknowledgment.
