Description - summary of the module content

Module description

Reconstructing the past history of climate change and human activity provides an invaluable insight into the role climate and anthropogenic activity have played in moulding landscapes. This module provides a practical introduction into the study of past environmental change over the last 21,000 years. This was a period of tumultuous change, characterised by violent swings in climate as the planet experienced the end of the Last Glacial Cycle. At the same time, with the rapid evolution of human society and the expansion of early cultures, the role of anthropogenic activity in driving the evolution of landscapes became ever more significant. This module will provide an overview of Late Quaternary environmental change and introduce a range of techniques used to reconstruct past environmental change from terrestrial archives. The module structure follows the process of palaeoenvironmental research from initial field collection of samples, through laboratory, data collection and analysis, and interpretation. The knowledge and skillset developed during this module will offer an excellent grounding to undertake a dissertation project in palaeoenvironmental science.

Module aims - intentions of the module

This module aims to provide an introduction to the principles and techniques used to reconstruct past climates and environments. The module content is driven by the research expertise of the teaching staff, which lie in the field of long-term ecology and palaeoenvironmental change. The syllabus provides some important background for dissertation topics, which may include recovery of sedimentological archives, development of chronologies, and work with biological proxies such as pollen, testate amoeba, and charcoal.

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 from the lecturer’s own work on the topic. This includes investigating environmental change over long timescales, the use of sedimentary records, chronology development and a range of microfossil analyses.

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 sampling design and statistical methods.
  • Providing you with the opportunity to engage in enquiry-led learning through exploring topics of long-term environmental and climate change.
  • Developing your communication skills and portfolio by delivering presentations, and a written report.
  • Developing good practice of contributing to and working in groups through practical exercises 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 submit a further assessment as necessary. If you are successful on referral, your overall module mark will be capped at 40%.
