The Northeast Greenland Ice Stream has recently seen significant change to its floating margins and has been identified as vulnerable to future climate warming. Inflow of warm Atlantic Intermediate Water (AIW) from the continental shelf has been obse...

Increased warm water intrusions could cause mass loss in East Antarctica during the next 200 years (2023)
Journal Article
Jordan, J. R., Miles, B., Gudmundsson, G., Jamieson, S., Jenkins, A., & Stokes, C. (2023). Increased warm water intrusions could cause mass loss in East Antarctica during the next 200 years. Nature Communications, 14(1), Article 1825. https://doi.org/10.1038/s41467-023-37553-2

The East Antarctic Ice Sheet (EAIS) is currently surrounded by relatively cool water, but climatic shifts have the potential to increase basal melting via intrusions of warm modified Circumpolar Deep Water (mCDW) onto the continental shelf. Here we u... Read More about Increased warm water intrusions could cause mass loss in East Antarctica during the next 200 years.

Holocene history of the 79° N ice shelf reconstructed from epishelf lake and uplifted glaciomarine sediments (2023)
Journal Article

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.
