T5 BRITICE-CHRONO: Constraining rates and style of marine-influenced ice sheet decay. Clark, C.D.*, Fabel, D., O’Cofaigh, C., Chiverrell, R., Scourse, J., Hindmarsh, R.C.A., Bradwell, T., Evans, D.J.A., Benneti, S., Freeman, S., Moreton, S. and Ballantyne, C., Bateman, M.D., Bigg, G.R., Burke, M., Davies, S., Duller, G., Gafeira, J., Greenwood, S., Gregoire, L., Hambrey, M., Hughes, A., Jamieson, S. Livingstone, S., McCarroll, D., McCarron, S., Monteys, X., Pienkowski, A., Praeg, D., Roberts, D., Rutt, I., Sejrup, H.P., Small, D., van Landeghem, K., Universities of Sheffield*, Glasgow, Durham, Liverpool, Bangor, Ulster, St Andrews, Swansea, Aberystwyth, Leeds, Maynooth, & British Antarctic Survey and British and Irish Geological Surveys, and Scottish Universities Environmental Research Centre, & Universities of Bergen & Stockholm Uncertainty exists regarding the future mass of the Antarctic and Greenland ice sheets and the change in sea level that would arise from any such changes. This is now an important scientific and societal issue that Quaternary scientists are addressing. If we want to know more about the mechanisms and rate of change of shrinking ice sheets, then why not examine one that has disappeared already and track its retreat through time? Here we provide an overview of the aims of the BRITICE-CHRONO consortium of Quaternary scientists and glaciologists, in a NERC-funded (£3.7 M) consortium project running from 2012 – 2017. Progress thus far can be gleaned from associated posters. Our project resonates with the ‘Quaternary Revolutions’ conference theme with regard to advances: in geochronometric dating; marine geophysics; RS-mapping and GIS compilation of Quaternary data; establishing on - offshore connections (e.g. IRD); and an improved interaction between empirical data and ice sheet modelling. The first objective is to produce an ice sheet wide empirical database of the timing and rates of change of the British-Irish Ice Sheet (BIIS). This is being achieved by focusing on 8 transects running from the continental shelf edge to a short distance (10s km) onshore and acquiring marine and terrestrial samples for geochronometric dating. The project includes funding for 587 radiocarbon, 140 OSL and 158 TCN samples for surface exposure dating; with sampling accomplished by two research cruises (NERC vessel) and 8 fieldwork campaigns. Results will reveal the timing and rate of change of ice margin recession for each transect, and combined with existing landform and dating databases, will be used to build an ice sheet-wide empirical reconstruction of retreat. Simulations using two numerical ice sheet models, fitted against the geochronological data, will yield insights regarding both their predictive abilities, and the significance of various factors such as sea-level rise, ocean/atmosphere forcing, bed topography and buttressing ice shelves on retreat rate. Keywords: British-Irish Ice Sheet; retreat; geochronometric dating; marine cruise; terrestrial fieldwork; GIS reconstruction; ice sheet modelling.
