  abstract = {{W}e find strong correlation between seasonal variation in {CGPS} time series and predicted response to annual snow load in {I}celand. {T}he load is modeled using {G}reen's functions for an elastic halfspace and a simple sinusoidal load history on {I}celand's four largest ice caps. {W}e derive {E} = 40 +/- 15 {GP}a as a minimum value for the effective {Y}oung's modulus in {I}celand, increasing with distance from the {E}astern {V}olcanic {Z}one. {W}e calculate the elastic response over all of {I}celand to maximum snow load at the ice caps using {E} = 40 {GP}a. {P}redicted annual vertical displacements are largest under the {V}atnajokull ice cap with a peak-to-peak seasonal displacement of similar to 37 mm. {CGPS} stations closest to the ice cap experience a peak-to-peak seasonal displacement of similar to 16 mm, consistent with our model. {E}ast and north of {V}atnajokull we find the maximum of annual horizontal displacements of similar to 6 mm resulting in apparent modulation of plate spreading rates in this area.},
