DOI: 10.1002/2017gl072648
Abstract: Tabular iceberg calving and ice shelf retreat occurs after full-thickness fractures, known as rifts, propagate across an ice shelf. A quickly evolving rift signals a threat to the stability of Larsen C, the Antarctic Peninsula's… read more here.

DOI: 10.1007/s13131-017-1142-8
Abstract: A massive iceberg, named A-68 by National Ice Center (NIC) officially, calved away from the Larsen C Ice Shelf in Antarctica on July 12, 2017. The iceberg A-68 is about 5 800 km2, weighs more… read more here.

DOI: 10.1016/j.epsl.2018.09.024
Abstract: Abstract We observe remarkably periodic patterns of seismicity rates and magnitudes at the Fimbul Ice Shelf, East Antarctica, correlating with the cycles of the ocean tide. Our analysis covers 19 years of continuous seismic recordings… read more here.

DOI: 10.1016/j.jmarsys.2016.07.002
Abstract: Abstract Both remotely sensed and in situ observations in austral summer of early 2012 in the Ross Sea suggest the presence of cold, low-salinity, and high-biomass eddies along the edge of the Ross Ice Shelf… read more here.

DOI: 10.1016/j.quascirev.2020.106738
Abstract: Abstract The Lambert Glacier-Amery Ice Shelf system (LGAISS) is the largest outlet glacier system in East Antarctica but its response to past climate variability is poorly constrained. In this study, we explore its dynamics over… read more here.

DOI: 10.1017/aog.2017.1
Abstract: ABSTRACT Calving is a complex process subject to several cooperating atmospheric, oceanographic and glaciological forcings that vary in space and time, and whose relative effects are challenging to separate. Statistical ‘Systems Analysis’ is commonly used… read more here.

DOI: 10.1017/aog.2018.31
Abstract: ABSTRACT Ice shelves regulate the rate of ice-sheet discharge along much of the Antarctic coastline. Pinning points, sites of localised grounding within floating ice, can in turn, regulate the flow and thickness of an ice… read more here.
