Jones, R.S., Whitehouse, P.L., Bentley, M.J., Small, D. and Dalton, A.S. (2019). Impact of glacial isostatic adjustment on cosmogenic surface-exposure dating. Quaternary Science Reviews. doi:10.1016/j.quascirev.2019.03.012

The paper investigated the spatial and temporal impact of glacial isostatic adjustment (GIA) on cosmogenic-nuclide production and corresponding surface-exposure ages over the last glacial-interglacial cycle. Correcting for GIA can make exposure age younger or older (by as much as ~2,500 years).

The paper introduces and describes iceTEA (Tools for Exposure Ages). The tools are designed to help users better analyse and understand spatial and temporal patterns within their data, leading to improved reconstructions of past glacier and ice sheet change.

Small, D., Bentley, M.J., Jones, R.S., Pittard, M.L. and Whitehouse, P.L. (2019). Antarctic ice sheet palaeo-thinning rates from vertical transects of cosmogenic exposure ages. Quaternary Science Reviews206, 65-80. doi:10.1016/j.quascirev.2018.12.024

Here vertical transects of surface-exposure ages were compiled to produce the first continent-wide database of past Antarctic Ice Sheet thinning rates. The generated thinning rates are similar to rates observed by satellites today, and occurred broadly in the same locations as modern ice sheet thinning.

(2018), Further constraint of the in situ cosmogenic 10Be production rate in pyroxene and a viability test for late Quaternary exposure dating. Quaternary Geochronology, 48, 121-132. doi:10.1016/j.quageo.2018.09.006.

The paper describes an improved method for extracting 10Be from pyroxene, and successful applications to a rock avalanche in New Zealand (to derive a production rate) and to a vertical transect of cobbles in Antarctica (to produce a consistent record of ice sheet thinning). Recommendations for further improvements to the method are also provided.

Here the long-term glacial history is reported for an Antarctic outlet glacier. Analysis of multiple nuclides (10Be and 26Al) revealed that this part of the East Antarctic ice sheet has not been stable, and instead, ice thickness has been fluctuating over glacial-interglacial cycles for several million years.

The paper used geomorphological and sedimentological analysis in combination with ice sheet model output to investigate the dynamics of a Late Glacial glacier. A dense suite of moraines records a multi-phase recessional history. We suggested that the glacier responded to sub-centennial scale climate fluctuations rather than to a single, prominent shift in climate.

Here the controls, along-flow sensitivity and time-dependent dynamics of a Transantarctic Mountains outlet glacier was investigated using modern observations and ice-flow modelling. The outcomes indicate that glaciers could experience greater ice loss in their confined, lower reaches through increased basal sliding, in addition to ocean melt, in a warming climate.

The paper provided direct evidence of ‘marine ice sheet instability’ in the geological record. Vertical transects of surface-exposure ages record an episode of rapid thinning in the mid-Holocene, which persisted for more than two and a half centuries, resulting in hundreds of metres of ice loss. Ice-flow simulations showed that this occurred from accelerated retreat into an over-deepened basin.
