Geoacoustic models for the Icelandic Basin

Abstract: Geoacoustic models inferred from amplitude versus range data at 220 Hz are presented for three locations in the Icelandic Basin. The data were obtained using a deep-towed pulsed cw source and two receivers anchored near the bottom. For ranges out to 4800 m, the data were analyzed using an iteration of forward models technique in which the parabolic equation method and a Hankel transform method were used sequentially to compute acoustic fields for different bottom parameters until best fits to the data were obt… Show more

“…Namely, the sediment properties are obtained as a solution of this type of inverse problem. Here it would be worthwhile to review some of the existing inverse methods [34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51].…”

“…Figure 2-6: Geoacousti--3del of the Icelandic Basin (sit---) based on direct me* surements of water sound velocity and seabed density, 3.5 kHz echo soundings, and the magnitude of the acoustic pressure measured at 220 Hz as a function of range [21]. Corresponding fields with similar characteristics were computed for the 54.6 m receiver.…”

“…A detailed description can be found in reference [21] (the data are from a region referred to as site B4). As shown in Figure 2-4, an acoustic source was towed away from two low-frequency receivers located at 1.2 m and 54.6 m from the bottom.…”
