This dataset contains inter-receiver Love wave traveltimes among 61 seismometers around the British Isles. The data was originally obtained by cross-correlation of ambient noise data recorded by the 61 receivers during 2001 to 2003, 2006 to 2007 and in 2010. More details can be found in Transdimensional Love-wave tomography of the British Isles and shear-velocity structure of the East Irish Sea Basin from ambient-noise interferometry (https://doi.org/10.1093/gji/ggw286) and Interrogating Subsurface Structures using Probabilistic Tomography: an example assessing the volume of Irish Sea basins (https://doi.org/10.1002/essoar.10510266.1).
