Trosolwg

Rwyf yn astudio ymateb rhanbarthau rhew parhaol alpaidd gogleddol i newidiadau yn yr hinsawdd dros raddfeydd gofodol-amserol amrywiol. Mae fy ymchwil yn canolbwyntio ar rew parhaol, dynameg llystyfiant a rhyddhau carbon. Defnyddiaf beilleg (dadansoddi paill) i ailadeiladu cynulliadau llystyfiant diweddar a synhwyro o bell i fodelu tymereddau arwyneb y tir o'r gorffennol (ar raddfa ddegawdol) a gwyrddni arwyneb y tir (NDVI). Hefyd mae gennyf ddiddordeb yn y rheolaethau gwahanol sydd gan nodweddion gwahanol yn yr ecosystem a phrosesau geomorffolegol o ran rhyddhau carbon o arwyneb y ddaear mewn amgylcheddau amrewlifol. Fy mhrif ardal astudio yw Jotunheimen yn ne Norwy.

Mae gennyf PhD mewn Daearyddiaeth Ffisegol (Prifysgol Abertawe, 2022) ac MSc mewn Gwasanaethau Ecosystemau (Prifysgol Caeredin, 2015) a BA Daearyddiaeth ac Astudiaethau Datblygu (Coleg y Brenin Llundain, 2013).

GE-007 Foundation Physical and Environmental Geography

This module complements topics taught in the Foundation Human Geography module (GE-008), to give an understanding of physical geography and the environment. The module considers the impacts of physical geography processes on human habitation, and how humans might mitigate against the effects of nature's extreme events. It also examines the complex issues surrounding human impacts on the landscape. Foundation Physical & Environmental Geography will pave the way for students to study Geography at Level 4 (Year 1).
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 in a wide variety of environments and contexts. Skills covered include essay writing, data analysis and map making
GEG252V Geographical Fieldwork skills: Vancouver

The module is concerned with identifying and defining geographical questions within the Vancouver and southern British Columbia context and applying relevant geographical skills, knowledge and techniques to these questions. The general aims are to observe, analyse and achieve an understanding of the varied geographical landscape and inherent features of Vancouver and southern British Columbia. 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 either the physical or human geography on the region and conduct project work appropriate to their specialism. The module comprises preparatory lectures in Swansea during teaching block 2 and a two-week field course, which typically runs in the last week of teaching block 2 into the first week of the Easter vacation.
