Description - summary of the module content

Module description

Mass loss from Greenland, Antarctica and glaciers around the world is contributing positively to eustatic sea-level rise. This has attracted a great deal of attention from scientists, media, the general public and policy makers around the world. Synchronous changes in glacier flow speeds point towards a regional control, either oceanographic or atmospheric. Through this module you will develop your understanding of glacier dynamics, research methods and knowledge related to polar environments. You will review current, high impact, research literature to evaluate contemporary hot-topics in glaciology. You will develop understanding of polar environments and the techniques used to monitor the crysophere, including field-work, remote- sensing and ice sheet modelling. You will critically engage with research methods and findings in order to gain a better understanding of limitations and uncertainty in understanding the response of the cryosphere to a warming world.

GEO2228 Cold Climate Geomorphology is not a prerequisite for this course as the material covered deals with contemporary ice masses. However, it may be beneficial to take this module to provide context and become familiar with some terminology.

Module aims - intentions of the module

This module aims to examine the major issues within this diverse research area of glaciology and polar environments. Themes tackled will include interactions between ice and the environment, mass balance, controls on ice flow, measurement approaches and future prediction. Being able to present a well-balanced critically evaluated argument is a transferable skill required for many graduate job opportunities. You will develop key transferable skills during this module including critical evaluation, research, presentation, communication, team work, self-motivation, spatial skills, image processing and the ability to work autonomously with others.

Enquiry-led learning is embedded in the module through guided independent practicals and assessment encouraging independent research. Much of the content includes research and applications for the lecturer’s own work on the topic. This includes investigating ice dynamics from satellite remote sensing, ice sheet model experiments and up to date daily sea-ice extent changes.

This module will help you develop skills to enhance your employability potential and career development through:

  • Enhancing your understanding and application of research skills including remote sensing and modelling.
  • Providing you with the opportunity to engage in enquiry-led learning through exploring hot topics of the cryosphere.
  • Developing your communication skills and portfolio by producing online presentation videos, written report and exam answer essays.
  • Developing good practice of contributing to, and working in groups through self-directed tutorials and formative work.
  • Encouraging you to think critically about the ways in which knowledge is applied and communicated in the media, literature and online.

Re-assessment notes

Deferral – if you miss an assessment for certificated reasons judged acceptable by the Mitigation Committee, you will normally be either deferred in the assessment or an extension may be granted. The mark given for a re-assessment taken as a result of deferral will not be capped and will be treated as it would be if it were your first attempt at the assessment.

Referral – if you have failed the module overall (i.e. a final overall module mark of less than 40%) you will be required to sit a further examination or submit a further assessment as necessary. If you are successful on referral, your overall module mark will be capped at 40%.
