  • BIOM25B Science Skills and Research Methods

    This intensive lecture and practical based module covers science skills for students wishing to pursue postgraduate studies, including MSc, MRes, MPhil and PhD degrees. It will teach students how to make good use of library and internet resources (including Web of Science, Voyager and Blackboard), to design and analyse their experiments, and to make presentations of their data during conferences and symposia. It will provide PG students in the Department of Biosciences (and other Departments in the College of Science) with the research and analytical skills necessary to carry out their research projects. It will teach them how to formulate and test scientific hypotheses, and how to generate and analyse scientific results using a variety of research methods. Lecture topics include Reporting and Presentation skills, Numerical skills, Philosophy and Methodology of Science, and Biostatistics. The lectures are taught during the first part of the Semester. The module is examined through a combination of CA (50%) and Examination in the form of a MCQ test (50%). Basic reading: Whitlock, M. and Schluter, D. (2014) The Analysis of Biological Data (Roberts & Co.). Crawley, M.J. (2005) Statistics: An Introduction Using R (Wiley). Original research papers given in reading list

  • GEG100 Geographical skills

    The aim of this module is to introduce the participants to essential geographical skills.These invaluable skills will become enhanced throughout their degree at Swansea University. Participants should be able to apply these techniques to data from a wide variety of environments and contexts. Presentation skills will be covered from the use of tables to the drawing of maps.

  • GEG132 Dynamic Earth Systems

    This module introduces the four main Earth systems: the atmosphere, geosphere, hydrosphere and biosphere and provides a sound understanding of the processes within each system, and of the interactions between them. This module forms the essential foundation for any more advanced study of physical geography. The atmosphere section deals with flows of energy and moisture and their role in controlling climate over both space and time. The geosphere section deals with the origin of Earth, describes the distribution of different rock types and introduces the concept of plate tectonics. The hydrosphere section focuses on the concepts of the hydrological cycle and main processes associated with the water fluxes. The biosphere section deals mainly with flows of energy and nutrients between Earth systems.

  • GEG264A Environmental Research Methods A

    The module covers research project design, data collection and some aspects of data analysis. Students are introduced to a range of laboratory and field techniques in physical geography. They gain experience in describing and interpreting results derived from laboratory techniques concerned with reconstructing the depositional history of sediments, chemical analysis of water and sediment from a variety of sources and the simulation of geomorphological processes.

  • GEG333 Geographical Research Frontiers

    This module provides students with the opportunity to demonstrate their competence as a Geographer by undertaking a critical analysis of a wide variety of literature-based sources in order to develop a cogent, substantial, and persuasive argument. While the Dissertation in Geography normally focuses on the design and execution of an evidenced-based research project that assesses the capacity of students to undertake effective data analysis and interpretation, the purpose of this module is to assess the extent to which students are capable of engaging with the academic literature at the frontier of a particular part of Geography. Students select from a wide range of research frontiers in Human and Physical Geography that have been identified by the academic staff within the Department. Given that this module emphasizes student-centred learning, none of the frontiers will have been covered in other modules, although in many cases modules will have taken students up to some of these frontiers. However, to orientate students and provide them with suitable points of departure and way-stations, there will be a brief introduction to each frontier and a short list of pivotal references disseminated via Blackboard. (Note: The topic selected by you must not overlap with the subject of your Dissertation. If there is any doubt about potential overlap, this must be discussed with your Dissertation Support Group supervisor and agreed in writing.)

  • GEG358 Climate of the last 1000 years

    The aim of this module is to provide the participants with the relevant skills to place the widely reported anthropogenic influences upon climate into the perspective of a naturally changing climatic system. The module focuses upon the techniques used to reconstruct changes in climate over the last 1000 years and presents reconstructions at differing temporal scales. The module is directed towards students with a basic scientific and mathematical background.

  • GEGM07 Principles of Environmental Dynamics

    This module aims to explain and understand past, present and potential future changes in the Earth's climate and environment. It provides a broad approach to environmental processes and dynamics operating on land, in the oceans and in the atmosphere on a global and regional scale. Emphasis is placed on the evidence available for reconstructing past environmental dynamics, the implications for present-day processes, future predictions and likely impacts.
