The central west coast of Ireland may exhibit the most spectacular boulder deposits from marine impacts during the Recent Holocene. They appear in similar aspects along the very exposed shorelines of the Aran Islands as well as along the sheltered shorelines within Galway Bay. Conclusions on their origin, storm waves or tsunamis, remain controversial. Not investigated so far are geo-archives like over-wash fans and well stratified sediment layers connected with the main boulder ridges. This new proposal is a pilot study to analyse the stratigraphy and sedimentology as well as the chronology of these deposits continuously along 25 km of the SE coast of the Galway Bay to compare their history with that of the boulder ridges and boulder clusters, and to contribute again to the enigma of coastal boulder transport.

爱尔兰的中西部海岸可能会在最近的全新世期间展示最壮观的海洋撞击巨石沉积物。它们出现在类似的方面沿着非常暴露的海岸线的阿兰群岛以及沿着庇护海岸线内的高威湾。关于它们的起源，风暴波或海啸的结论仍然存在争议。到目前为止，还没有调查过的地质档案，如过冲扇和分层沉积层连接的主要巨石山脊。这项新的建议是一项试点研究，分析地层学和沉积学以及这些存款的年代连续沿着25公里的东南海岸的高威湾比较他们的历史与巨石脊和巨石群，并再次贡献的沿海巨石运输之谜。
