Reconstructing former ice sheet history and glaciogenic sediment fluxes surrounding Baffin Bay during and since the Last Glacial Maximum (LGM) is a major scientific challenge. Here, a new multi-proxy analysis of sediments from a central Baffin Bay (B...

Ice-ocean interactions at the Northeast Greenland Ice stream (NEGIS) over the past 11,000 years (2023)
Journal Article
Lloyd, J., Ribeiro, S., Weckström, K., Callard, L., Ó Cofaigh, C., Leng, M., Gulliver, P., & Roberts, D. (2023). Ice-ocean interactions at the Northeast Greenland Ice stream (NEGIS) over the past 11,000 years. Quaternary Science Reviews, 308, Article 108068. https://doi.org/10.1016/j.quascirev.2023.108068

Recent observations have identified increased mass loss from Greenland marine-terminating outlet glaciers (MTOG) with implications for global sea-level rise and wider ocean circulation. The flow of Atlantic-sourced waters to the Greenland margin is t... Read More about Ice-ocean interactions at the Northeast Greenland Ice stream (NEGIS) over the past 11,000 years.

Holocene history of the 79° N ice shelf reconstructed from epishelf lake and uplifted glaciomarine sediments (2023)
Journal Article
Smith, J. A., Callard, L., Bentley, M. J., Jamieson, S. S., Sánchez-Montes, M. L., Lane, T. P., Lloyd, J. M., McClymont, E. L., Darvill, C. M., Rea, B.

The Cryosphere, 17(3), https://doi.org/10.5194/tc-17-1247-2023

Nioghalvfjerdsbrae, or 79◦ N Glacier, is the largest marine-terminating glacier draining the Northeast Greenland Ice Stream (NEGIS). In recent years, its ∼ 70 km long fringing ice shelf (hereafter referred to as the 79◦ N ice shelf) has thinned, and...

The geomorphological record of an ice stream to ice shelf transition in Northeast Greenland (2023)
Journal Article
Lane, T., Darvill, C., Rea, B., Bentley, M., Smith, J., Jamieson, S., Ó Cofaigh, C., & Roberts, D. (2023). The geomorphological record of an ice stream to ice shelf transition in Northeast Greenland. Earth Surface Processes and Landforms, 48(7), 1321-1341. https://doi.org/10.1002/esp.5552

Understanding ice stream dynamics over decadal to millennial timescales is crucial for improving numerical model projections of ice sheet behaviour and future ice loss. In marine-terminating settings, ice shelves play a critical role in controlling i... Read More about The geomorphological record of an ice stream to ice shelf transition in Northeast Greenland.
