|Module Title||VOLCANIC ACTIVITY AND ENVIRONMENTAL CHANGE|
|Co-ordinator||Dr John Grattan|
|Course delivery||Lecture||22 Hours 11 x 2 hours|
|Assessment||Exam||2 Hours Written examination.||50%|
|Course work||Coursework to be submitted by the end of week 9.||50%|
|Resit assessment||Resit: Examinations will have the same format. Students who fail the continuous assessment component of the module will be set a recovery assessment which will take the form of an extended essay to be submitted to the Institute of Geography and Earth Sciences General Office by the day of the resit examination.|
Module Outline (Lecture Themes)
1. Volcanoes and Climate
2. Tephra versus Sulphur. How do Volcanic eruptions generate climate change?
3. Circulation Response.
North Atlantic circulation. The El Ni?o. Monsoon disruption.
4. Ice Sheet and Glacier Response.
Do ice sheets respond to volcanic activity? What is the link between volcanic activity and the Pleistocene glacial advances?
5. Palaeoecological Data.
Does independent ecological data verify or contradict assumptions re volcanic eruptions and climate?
6. The Laki eruption of 1783.
7. The environmental impact of volcanic eruptions.
8. The Eruption Of Tambora And The Year Without A Summer.
9. The Distal Impact Of Volcanic Aerosols.
10. The Hekla eruptions. Direct impact on the British Isles?
11. The extinction of the Dinosaurs.
12. Mt. Pinatubo, impacts on climate and stratospheric ozone.
13. Sun and dust versus greenhouse gases.
14. Summary and roundup.
1. Knowledge of the subject: Students are expected to acquire a clear understanding of the mechanisms by which volcanic eruptions may bring about environmental change. Related to this will be the understanding of a wide range of environmental, climatic, sedimentary and ecological systems.
2. Core concepts: Students will develop a clear theoretical and philosophical framework, which will allow them to assess the degree of inter relationship between different environmental systems. Central to this will be an understanding of the sensitivity of environmental systems to external forcing mechanisms.
Module objectives / Learning outcomes
General And Transferable Skills: Students will develop their research skills and the ability to construct a synthesis from often conflicting research. They should become confident in writing band in supporting their arguments in a coherent, academic fashion. The student's ability to use research concepts, in particular the use and application of multiple working hypotheses will be enhanced. The value of historical research as a tool in the reconstruction of environmental change will be explored. Students will become confident in the use of computers in the investigation of environmental change. Use of electronic information systems via the Internet will be encouraged.
