Quantifying flow and stress in ice mélange, the world’s largest granular material. [PDF]

, 2018
Tidewater glacier fjords are often filled with a collection of calved icebergs, brash ice, and sea ice. For glaciers with high calving rates, this “m ́elange” of ice can be jam-packed, so that the flow of ice fragments is mostly determined by ...

Seabed corrugations beneath an Antarctic ice shelf revealed by autonomous underwater vehicle survey: Origin and implications for the history of Pine Island Glacier [PDF]

, 2013
Ice shelves are critical features in the debate about West Antarctic ice sheet change and sea level rise, both because they limit ice discharge and because they are sensitive to change in the surrounding ocean.

‘Sometimes, I would look at my books and cry because I felt like I was left behind’: Understanding the learning of Indigenous girls during the COVID‐19 pandemic in the districts of Chongwe and Solwezi in Zambia

British Educational Research Journal, EarlyView.
Abstract Grounded in principles of epistemic justice, this article examines the educational impacts of Zambia's COVID‐19 school closures on Indigenous girls in two districts and highlights community‐led pathways for resilience. National responses prioritised broadcast and digital delivery but presupposed access to electricity, digital devices and ...

Beyond standardisation, subjects and syllabi: How primary schools organise for arts richness in an era of curriculum reform

British Educational Research Journal, EarlyView.
Abstract As England embarks on its first comprehensive curriculum review in fifteen years, this paper offers critical insights from schools that sustained arts‐rich provision despite a policy landscape hostile to creative subjects. Drawing on data from the Researching Arts‐rich Primary Schools (RAPS) project—a mixed‐methods study of 76 arts‐rich ...

Detecting Arctic Icebergs in Sea Ice in L-Band SAR Images Using a Multiscale CFAR Algorithm

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This study proposes a multiscale extension of the well-known constant false alarm rate (CFAR) outlier detection method for the detection of icebergs in L-band synthetic aperture radar (SAR) images. The proposed method offers the possibility to accurately

Iron in Glacial Systems: Speciation, Reactivity, Freezing Behavior, and Alteration During Transport

Frontiers in Earth Science, 2018
A more insightful view of iron in glacial systems requires consideration of iron speciation and mineralogy, the potential for iron minerals to undergo weathering in ice-water environments, the impact of freezing on concentration and speciation, and ...

‘School is their whole world’: Teachers' perspectives on loneliness among children and adolescents from England and mainland China

British Educational Research Journal, EarlyView.
Abstract As front‐line observers and active participants in pupils' daily lives, teachers closely monitor pupils' social interactions, emotional states and behavioural changes. Their unique perspective enables them to detect problems in the social lives of their pupils that may not be immediately visible to peers, parents or mental health professionals.

The use of the sonar complex when examining the lower surface of the ice

Российская Арктика, 2019
The article discusses the methodological issues of applying the sonar method to determine the shape of the lower surface of ice directly from the ice surface in the Arctic, as a complex solution for morphometric studies.

Applicability of ERTS for surveying Antarctic iceberg resources [PDF]

The author has identified the following significant results. This investigation explores the applicability of ERTS to (1) determine the Antarctic sea ice and environmental behavior that may influence the harvesting of icebergs, and (2) monitor iceberg ...
