Description | |
Summary | The iGlass project (using Inter-GLacials to Assess future Sea-level Scenarios) data set will comprise: acquisition of new relative sea-level data (sediments and microfossils - diatoms and foraminifera) from estuarine environments, speleothems (cave deposits), corals as well as chemical composition of marine plankton shells (foraminifera) contained in sediment cores, from around the world; palaeodata synthesis of interglacial sea level and climate; and modelling of isostatic, climate and sea-level changes and interactions during past interglacials. The iGlass consortium aims to better understand the processes of ice-sheet and sea-level response to climatic forcing using data from the recent geological past. The data will cover the time period between 427 and 115 thousand years before present covering Marine Isotope Stages (MIS) 5, 7, 9 and 11. The dataset currently includes the synthesis of high-latitude air and sea surface temperature from the last Interglacial MIS5 between 115 and 130 thousand years before present. Sediment coring and the analysis of microfossils within these, will acquire new sea-level data. There will be geophysical modelling of vertical land movements and gravitational effects, which cause deviations of regional sea level from the global mean trend. Investigation of climate/ice-sheet/sea-level interactions using both observations and modelling, to reveal the underlying processes. Coring will take place in Norfolk and the Red Sea and speleothems will be investigated in Bermuda. Data synthesis and some model output will concentrate on the high northern and southern latitudes; other model output will be global. iGlass is funded by the UK Natural Environment Research Council and comprises the following research institutions; University of Southampton, National Oceanography Centre (NOC), University of York, University of Oxford, University of Durham, University of Bristol, University of Reading, University of Cambridge and British Antarctic Survey (BAS). It also includes two academic partners; University of Ottawa and Australian National University and three the non-academic partners; UKCIP, Environment Agency and Willis Ltd. There are also external researchers based at Oregon State University and National Center for Atmospheric Research. Currently the synthesis of high-latitude air and sea surface temperature from the last Interglacial MIS5 and the synthesis of coral indicators of past sea-level change are available from BODC. Other data will be added in due course. |
