Mass Loss of Glaciers and Ice Caps Across Greenland Since the Little Ice Age (2023)
Journal Article
Carrivick, J. L., Boston, C. M., Sutherland, J. L., Pearce, D., Armstrong, H., Bjørk, A., …Smith, M. W. (2023). Mass Loss of Glaciers and Ice Caps Across Greenland Since the Little Ice Age. Geophysical Research Letters, 50(10), Article e2023GL103950. https://doi.org/10.1029/2023gl103950

Glaciers and ice caps (GICs) are important contributors of meltwater runoff and to global sea level rise. However, knowledge of GIC mass changes is largely restricted to the last few decades. Here we show the extent of 5327 Greenland GICs during Litt... Read More about Mass Loss of Glaciers and Ice Caps Across Greenland Since the Little Ice Age.

60 million years of glaciation in the Transantarctic Mountains (2022)
Journal Article
Barr, I. D., Spagnolo, M., Rea, B. R., Bingham, R. G., Oien, R. P., Adamson, K., …Tomkins, M. D. (2022). 60 million years of glaciation in the Transantarctic Mountains. Nature Communications, 13(1), Article 5526. https://doi.org/10.1038/s41467-022-33310-z

The Antarctic continent reached its current polar location ~83 Ma and became shrouded by ice sheets ~34 Ma, coincident with dramatic global cooling at the Eocene-Oligocene boundary. However, it is not known whether the first Antarctic glaciers formed... Read More about 60 million years of glaciation in the Transantarctic Mountains.

Controls on the altitude of Scandinavian cirques: What do they tell us about palaeoclimate? (2022)
Journal Article
Oien, R. P., Barr, I. D., Spagnolo, M., Bingham, R. G., Rea, B. R., & Jansen, J. (2022). Controls on the altitude of Scandinavian cirques: What do they tell us about palaeoclimate?. Palaeogeography, Palaeoclimatology, Palaeoecology, 600, 111062. https://doi.org/10.1016/j.palaeo.2022.111062

Cirques are glacially eroded, bowl-shaped depressions, characterised by steep headwalls and flat or overdeepened floors. Given their association with past glaciers, cirques are sometimes used as proxies for palaeoclimate. However, cirques are shaped...

Testing the area–altitude balance ratio (AABR) and accumulation–area ratio (AAR) methods of calculating glacier equilibrium-line altitudes (2021)
Journal Article
Oien, R. P., Rea, B. R., Spagnolo, M., Barr, I. D., & Bingham, R. G. (2022). Testing the area–altitude balance ratio (AABR) and accumulation–area ratio (AAR) methods of calculating glacier equilibrium-line altitudes. Journal of Glaciology, 68(268), 357-368. https://doi.org/10.1017/jog.2021.100

In this study, we compare equilibrium-line altitudes (ELAs) calculated using the area–altitude balance ratio (AABR) and the accumulation–area ratio (AAR) methods, with measured ELAs derived from direct field observations. We utilise a GIS toolbox to... Read More about Testing the area–altitude balance ratio (AABR) and accumulation–area ratio (AAR) methods of calculating glacier equilibrium-line altitudes.

Cool deltas: Sedimentological, geomorphological and geophysical characterization of ice‐contact deltas and implications for their reservoir properties (Salpausselkä, Finland) (2021)
Journal Article
Kurjański, B., Rea, B. R., Spagnolo, M., Cornwell, D. G., Howell, J., Comte, J., …Gibbard, P. L. (2021). Cool deltas: Sedimentological, geomorphological and geophysical characterization of ice‐contact deltas and implications for their reservoir properties (Salpausselkä, Finland). Sedimentology, 68(7), 3057-3101. https://doi.org/10.1111/sed.12884

Sediments deposited by glacial meltwaters (for example, ice-contact delta deposits) form permeable packages in the subsurface that can act as reservoirs for both water and hydrocarbons. They are also an important source of aggregate for the construct...

Climatic controls on the equilibrium-line altitudes of Scandinavian cirque glaciers (2019)
Journal Article
Oien, R. P., Spagnolo, M., Rea, B. R., Barr, I. D., & Bingham, R. G. (2020). Climatic controls on the equilibrium-line altitudes of Scandinavian cirque glaciers. Geomorphology, 352, Article 106986. https://doi.org/10.1016/j.geomorph.2019.106986

The equilibrium-line altitudes (ELAs) of reconstructed palaeoglaciers have been widely used to assess palaeoclimatic conditions, yet this concept has rarely been tested using modern glaciers. To address this shortcoming, correlations between the ELAs... Read More about Climatic controls on the equilibrium-line altitudes of Scandinavian cirque glaciers.
