35 Ice sheets, glaciers, and landscapes, oh my! (Posters)

Glaciers and ice sheets shaped the landscape of the Northeast. Ice continues to shape the landscape of alpine and polar regions. We welcome submissions on glaciers & ice sheets of any size, shape, age, and location.

Abstract

This presentation introduces part of an historically famous coastal cliff-section Quaternary sediment sequence infilling Killiney Bay, eastern Ireland. The Killiney-Bray section is over 5km long and was the location of heated debate over the origin of 'glacial drift', as the regionally (Britain and Ireland) famous Irish Sea Tiil, a shell-bearing diamict, outcrops here and inland on nearby high ground. This presentation introduces some aspects of the glacigenic sediment sequence, the context for their deposition and contrasting models for their genesis. It offers a review of their interpretation and places the sediments in the emerging geochronological framework for deglaciation of the Irish Sea Basin (ISB), an important drainage outlet of the last British-Irish Ice Sheet (BIIS) once containing the Irish Sea Ice Stream (ISIS).
