Pattern, style and timing of British–Irish Ice Sheet retreat: Shetland and northern North Sea sector

Journal of Quaternary Science, Volume 36, Issue 5, Page 681-722, July 2021., 2021
ABSTRACT The offshore sector around Shetland remains one of the least well‐studied parts of the former British–Irish Ice Sheet with several long‐standing scientific issues unresolved. These key issues include (i) the dominance of a locally sourced ‘Shetland ice cap’ vs an invasive Fennoscandian Ice Sheet; (ii) the flow configuration and style of ...

Pattern, style and timing of British–Irish Ice Sheet advance and retreat over the last 45 000 years: evidence from NW Scotland and the adjacent continental shelf

Journal of Quaternary Science, Volume 36, Issue 5, Page 871-933, July 2021., 2021
Abstract Predicting the future response of ice sheets to climate warming and rising global sea level is important but difficult. This is especially so when fast‐flowing glaciers or ice streams, buffered by ice shelves, are grounded on beds below sea level. What happens when these ice shelves are removed?

Fast Simulation Study of Muon Absorption Radiography Based on Energy Loss Calculation

Yuanzineng kexue jishu, 2022
Using natural cosmic ray muon as radiation source, muon absorption radiography can realize nondestructive detection of large-scale geological objects. Simulation analysis is an important step in the application of muon absorption radiography.

Muon tomography for railway tunnel imaging

Physical Review Research, 2020
Cosmic ray muon radiography utilizes highly penetrating cosmic ray muons to image the density profile of an object of interest. Here we report on a trial to use a portable field-deployable cosmic ray muon tracking system in order to image the whole ...

A novel technique to detect special nuclear material using cosmic rays [PDF]

Geoscientific Instrumentation, Methods and Data Systems, 2012
Resistive plate chambers (RPCs) are widely used in high energy physics for both tracking and triggering purposes, due to their excellent time resolution, rate capability, and good spatial resolution. RPCs can be produced cost-effectively on large scales,

Three‐dimensional density structure of La Soufrière de Guadeloupe lava dome from simultaneous muon radiographies and gravity data

Geophysical Research Letters, 2017
Muon imaging has recently emerged as a powerful method to complement standard geophysical tools in the understanding of the Earth's subsurface. Muon measurements yield a “radiography” of the average density along the muon path, allowing to image large ...
