Characteristics of the sticky spot of Kamb Ice Stream, West Antarctica [PDF]
, 2017 Amplitude analysis of reflection seismic data reveals the presence of highly variable bed conditions under the main sticky spot and adjacent regions of the Kamb Ice Stream (KIS—formerly ice stream C).

Insights into ice stream dynamics through modelling their response to tidal forcing [PDF]
The Cryosphere, 2014 The tidal forcing of ice streams at their ocean boundary can serve as a natural experiment to gain an insight into their dynamics and constrain the basal sliding law.

Multianalytical provenance analysis of Eastern Ross Sea LGM till sediments (Antarctica): Petrography, geochronology, and thermochronology detrital data [PDF]
, 2017 In order to reveal provenance of detrital sediments supplied by West Antarctic Ice Sheet (WAIS), 19 glaciomarine cores of Last Glacial Maximum age were analyzed from Eastern Ross Sea and Sulzberger Bay.

Come together over me: Cells that form the dermatocranium and chondrocranium in mice
The Anatomical Record, EarlyView., 2023 Abstract Most bone develops either by intramembranous ossification where bone forms within a soft connective tissue, or by endochondral ossification by way of a cartilage anlagen or model. Bones of the skull can form endochondrally or intramembranously or represent a combination of the two types of ossification.

Spatiotemporal Dynamics of Ice Streams Due to a Triple-Valued Sliding Law [PDF]
, 2010 We show that a triple-valued sliding law can be heuristically motivated by the transverse spatial structure of an ice-stream velocity field using a simple one-dimensional model.

Softening of Temperate Ice by Interstitial Water
Frontiers in Earth Science, 2021 Ice at depth in ice-stream shear margins is thought to commonly be temperate, with interstitial meltwater that softens ice. Models that include this softening extrapolate results of a single experimental study in which ice effective viscosity decreased ...

The motion of ice stream margins [PDF]
Journal of Fluid Mechanics, 2013 AbstractThe recent article by Schoof (J. Fluid Mech., vol. 712, 2012, pp. 552–578) provides a technically demanding solution to the problem of determining ice-stream margin evolution. It is important in opening the way to the future theoretical description of how the ice sheets will melt and sea level will rise as the climate warms.

The kinematical and space structures of IC 2391 open cluster and moving group with Gaia-DR2 [PDF]
, 2019 The kinematical parameters, spatial shape and structure of the open cluster IC 2391 and the associated stellar stream are studied here using Gaia-DR2 (GDR2) astrometry data. The apex positions are determined for the open cluster IC 2391 (data taken from Cantat-Gaudin et al.) and for the kinematical streams stars mentioned in Montes et al.

Meltwater generation in ice stream shear margins: case study in Antarctic ice streams
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2022 Liquid water within glacier ice and at the glacier beds exerts a significant control on ice flow and glacier stability through a number of processes, including altering the rheology of the ice and lubricating the bed. Some of this water is generated as melt in regions of rapid deformation, including shear margins, due to heating by viscous dissipation.
