Uchafbwyntiau Gyrfa
Ymchwil
Prif Wobrau
Dynameg Amgylcheddol
Mae ein hymchwil yn canolbwyntio ar amrywioldeb amgylcheddol yn ystod y cyfnod Cwaternaidd ac effeithiau newidiadau yn yr hinsawdd yn y dyfodol. Ffocws ein hymchwil yw’r rhanbarthau hynny sy’n arbennig o sensitif i newidiadau yn yr hinsawdd (gan gynnwys hinsoddau trofannol ac oer a’r rheiny sy’n dioddef o danau gwyllt). Mae hefyd yn ystyried y rhyngweithio rhwng newidiadau yn yr hinsawdd, ymyrraeth ddynol a digwyddiadau trychinebus.

This module investigates hazardous aspects of Earth¿s natural environment and how society relates to them. Introductory principles include the definition of natural hazard, disaster, risk and loss, and approaches to reducing risk and managing disasters. Major types of natural hazard are studied in order to understand how they operate, where, and how frequently they are likely to occur. Hazardous consequences are explored, as well as how society can respond to hazardous events. Key aspects include discussion of primary and secondary hazards, prediction, forecasting and monitoring of hazards, and understanding how their harmful effects can be minimised. Natural hazards considered during this module include volcanic eruptions, earthquakes, tsunamis, wildfires, landslides, extreme weather events, flooding, avalanches and Mega Hazards. The module will also consider the concept of ¿Humans as Hazards¿. Lectures consider general principles as well as case studies. Practical classes reinforce concepts learned in lectures. The practical aspect of the work will culminate in a disaster management simulation day.

GEG252SI Geographical Fieldwork Skills: Isles of Scilly
The module is concerned with identifying and defining climate and environment change questions within the Isle of Scilly, which serves as an example of a region with unique habitats and climate in the UK and applying relevant environmental and climate science skills, knowledge and techniques to these questions. The general aims are to observe, analyse and achieve an understanding of the varied micro-climates and habitat features of the Isle of Scilly. Students taking this module will gain experience in research design, methodologies, data analysis and presentation methods, including seminars, posters and reports. Students taking this field course focus on both climate change, sustainable living and the environment and conduct project work appropriate to their specialism. The module comprises preparatory sessions in Swansea during teaching block 2 and one week field course, which typically runs in the last week of teaching block 2.

GEG331 Dissertation Report: Geography
The dissertation is an original, substantive and independent research project in an aspect of Geography. The dissertation research project is based on 20 - 25 days of primary research (e.g fieldwork, lab work, archive work) and several months of analysis and write-up. The end result must be less than 10,000 words of text. The dissertation offers you the chance to follow your personal interests and to demonstrate your capabilities as a Geographer. During the course of your dissertation, you will be supported by a peer-led discussion group and a staff supervisor. Lectures and guidance are delivered via this module and peer and staff led Dissertation Support Groups are delivered via GEG332. Participating in Dissertation Support Groups is vital, and is assessed and, in these groups, students will provide constructive criticism to fellow students undertaking related research projects, learning from their research problems and subsequent solutions. This support and supervision is delivered through GEG332, which is a co- requisite.

GEG332 Dissertation Support: Geography
This module provides structured, student-led peer-group support and academic staff group supervision for students undertaking the 30-credit 'Dissertation Report: Geography' module. This support and supervision is assessed through the submission of the Dissertation Outline and the Dissertation Support Group Reflection and Attendance Log. Working within a supervised Student Peer Group, students have the opportunity to provide constructive criticism to fellow students undertaking related research projects, learning from their research problems and subsequent solutions. Group sessions are the main support provision as student¿s work through their Dissertation. This module complements the 'Dissertation Report: Geography' module, which is a co-requisite.

GEG363 Volcanology
In this module, students will study magmatic and volcanic processes, from source to surface. We will follow the journey of magma, from its production inside the Earth, to eruption at the surface through volcanoes, and injection of volcanic ash and gases into the atmosphere. The module will cover magma generation, storage and evolution, ascent and eruption. Students will gain an understanding of processes underpinning eruptive styles and interpretation of these processes from the volcanic products. The module also explores how volcanism affects our planet¿s climate. Delivery of the module will include a combination of on-campus sessions and a field course to the Eifel Volcanic Field (Germany). The field course will enable in-situ study of diverse volcanic landforms and products, formed via a wide range of eruptive styles, including effusive and explosive eruptions. During the field course, students will study various aspects of volcanic geology, including learning how to observe, measure and interpret volcanic rocks and deposits. The module has a strong geological focus, and therefore a keen interest in geology and some previous knowledge of geology is highly recommended.
