A comparison of annual layer thickness model estimates with observational measurements using the Berkner Island ice core, Antarctica (2017)
Journal Article

A model to estimate the annual layer thickness of deposited snowfall at a deep ice core site, compacted by vertical strain with respect to depth, is assessed using ultra-high-resolution laboratory analytical techniques. A recently established techniq... Read More about A comparison of annual layer thickness model estimates with observational measurements using the Berkner Island ice core, Antarctica.

Deglacial history of the Pensacola Mountains, Antarctica from glacial geomorphology and cosmogenic nuclide surface exposure dating (2017)
Journal Article

The retreat history of the Antarctic Ice Sheet is important for understanding rapid deglaciation, as well as to constrain numerical ice sheet models and ice loading models required for glacial isostatic adjustment modelling. There is particular debat... Read More about Deglacial history of the Pensacola Mountains, Antarctica from glacial geomorphology and cosmogenic nuclide surface exposure dating.

Glacial Isostatic Adjustment in response to changing Late Holocene behaviour of ice streams on the Siple Coast, West Antarctica (2016)
Journal Article

The Siple Coast region of Antarctica contains a number of fast-flowing ice streams, which control the dynamics and mass balance of the region. These ice streams are known to undergo stagnation and reactivation cycles, which lead to ice thickness chan...

An examination of spatial variability in the timing and magnitude of Holocene relative sea-level changes in the New Zealand archipelago (2015)
Journal Article

Holocene relative sea-level (RSL) changes have been reconstructed for four regions within the New Zealand archipelago: the northern North Island (including Northland, Auckland, and the Coromandel Peninsula); the southwest coast of the North Island; t...

Uplift rates from a new high-density GPS network in Palmer Land indicate significant late Holocene ice loss in the southwestern Weddell Sea (2015)
Journal Article

The measurement of ongoing ice-mass loss and associated melt water contribution to sea-level change from regions such as West Antarctica is dependent on a combination of remote sensing methods. A key method, the measurement of changes in Earth's grav...

Antarctic ice rises and rumples: Their properties and significance for ice-sheet dynamics and evolution (2015)
Journal Article

Locally grounded features in ice shelves, called ice rises and rumples, play a key role buttressing discharge from the Antarctic Ice Sheet and regulating its contribution to sea level. Ice rises typically rise several hundreds of meters above the sur... Read More about Antarctic ice rises and rumples: Their properties and significance for ice-sheet dynamics and evolution.

Incomplete separability of Antarctic plate rotation from glacial isostatic adjustment deformation within geodetic observations (2015)
Journal Article

Geodetic measurements of Antarctic solid Earth deformation include signals from plate rotation and glacial isostatic adjustment (GIA). Through simulation, we investigate the degree to which these signals are separable within horizontal GPS site veloc...

Effect of GIA models with 3D composite mantle viscosity on GRACE mass balance estimates for Antarctica (2015)
Journal Article

Seismic data indicate that there are large viscosity variations in the mantle beneath Antarctica. Consideration of such variations would affect predictions of models of Glacial Isostatic Adjustment (GIA), which are used to correct satellite measureme...

Rapid bedrock uplift in the Antarctic Peninsula explained by viscoelastic response to recent ice unloading (2014)
Journal Article

Since 1995 several ice shelves in the Northern Antarctic Peninsula have collapsed and triggered ice-mass unloading, invoking a solid Earth response that has been recorded at continuous GPS (cGPS) stations. A previous attempt to model the observation... Read More about Rapid bedrock uplift in the Antarctic Peninsula explained by viscoelastic response to recent ice unloading.
