This dataset accompanies the IEEE Journal of Oceanic Engineering Special Issue on Verification and Validation of Airgun Source Signature and Sound Propagation Models. The special issue has is its origins in the International Airgun Modelling Workshop (IAMW) held in Dublin, Ireland, on 16 July 2016 (Ainslie et al., 2016). For a number of specified airgun scenarios, participants in the IAMW were asked to use their models to compute source waveforms s(t) corresponding to three airgun sources, including two airgun arrays, as well as sound pressure and sound particle acceleration at specified positions relative to the sources. IAMW participants were given the option of either running their own source signature model(s) or to use data produced by Agora 2 (Sertlek and Ainslie, 2015) and made available by the workshop organizers. Agora 2 is a freely available Matlab® program (www oalib).


Three sources, denoted S1, S2 and S3 are specified by Ainslie et al. (2019). S1 is a single airgun. S2 is a line array comprising six airguns, the third of which is the same airgun as S1. S3 is a planar array comprising three nominally parallel sub-arrays, the centre sub-array of which is the same as S2. This dataset provides the Agora 2 source waveforms (“notional signatures”) of the individual airguns for the three sources S1, S2 and S3.
