Objectives | The objectives of the cruise were to investigate the crustal and upper mantle structure of the Iceland-Faroe ridge and to develop techniques of reflection shooting using an airgun source. During the first half of the cruise, it was planned to use the two-ship seismic refraction method to determine crustal thickness and layering. After this, the Moray Firth would return to the Tyne leaving Arran Firth to carry out seismic reflection measurements of layer 1 in conjunction with magnetometer measurements on the ridge. A subsidiary aim was to test and use disposable sono-buoys in conjunction with the airgun relfection source. |
