Uncrewed Aerial Vehicles (UAVs)

This UAV article was written by Lauren Rawlins, University of York This article introduces UAVs, or drones, and how we can use them in glaciology and geomorphology. We can stitch together the thousands of images taken from a UAV from vantage point high in the sky to create new high-resolution image and 3D model of … Read more

Unlocking ice-flow pathways using glacial erratics

This article was written by Dr Jenna Sutherland. All photos and images are credited to Jenna Sutherland. A long history of scientific debate Along the east coast of the UK, spectacular coastal sections expose sediments that were deposited by the last British Irish Ice Sheet (BIIS) around 21,000 years ago. For many years, Late Devensian … Read more

Glacial Sedimentology

Other techniques that are well used in glaciology include remote sensing of glacier change. We can map the world’s glaciers using satellite imagery, including taking inventories of glaciers, and map glacier recession from space. We can then use satellite imagery to observe glaciers receding around the Antarctic Peninsula, and in Patagonia.

Thin-section analysis

This section is taken from Bethan Davies’ PhD thesis. Introduction to micromorphology | Sample Collection and Preparation | Sample analysis | References | Comments | Introduction to micromorphology Micromorphology, or thin-section analysis, is the microscopic examination of the composition and structure of sediments. It was originally developed in soil science, with concepts of plasmic fabric … Read more

Clast Shape, Till Fabrics and Striae

This section is taken from Bethan Davies’ PhD thesis. Clast Angularity-Roundness | Clast Macro-Fabric Analysis | Striae Orientation | References | Comments | Clast Angularity-Roundness Clasts inherit their shapes from the surrounding environment; erosion, transportation and weathering give clasts distinctive geomorphological signatures1. Angularity-roundness is simple to measure in the field when undertaking till-fabric analysis. Descriptive … Read more
