About

John Hiemstra obtained his PhD degree from the University of Amsterdam (2001). His thesis was on the microscopic characterisation and interpretation of Antarctic continental shelf sediments. The objective was to study changes in the extent of the grounded ice sheet through time.

He was a Marie Curie postdoctoral researcher at the University of Glasgow (2002-2004). He currently holds a position as Associate Professor at Swansea University.

He teaches courses in Physical Geography and Geology, and is the coordinator of the MSc in Geographic Information and Climate Change. He supervises and has supervised several PhD students, and has examined both internally and externally.

His research focuses on the reconstruction of past glacial environments, and the study of more recent glacier and permafrost dynamics in response to changing climate. He has been involved in fieldwork in areas across the world, including the British Isles, Norway, Iceland, Canada, Morocco, Japan and Antarctica.

He has published extensively in leading international scientific journals and contributed to several books and field guides. He has reviewed for >25 journals, holds editorial positions with The Holocene, Proceedings of the Geologists’ Association and Scientific Reports, and is a member of the Quaternary Research Association Executive Board.

Taught Modules

EG-2000 Geomechanics I

Geomechanics is the study of the mechanical behaviour of geological material, namely rocks and soils. The understanding of these concepts is crucial owing to the importance of these materials in the stability of supported structures. This 20 credit module, spanning both TB1 and TB2, introduces the fundamental theory associated with the mechanical properties of both forms of geological material. On completion of this module, the student will be prepared to look at further advanced topics in Geomechanics II.

GEG133 Natural Hazards and Society

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. Lecture material considers general principles as well as case studies. The module is compulsory for students taking BSc Environmental Geoscience.
GEG277 Geographical Methods and Data Analysis

This core 20-credit module introduces a variety of physical and human geography methods, along with data analysis. The module builds upon student knowledge and covers research design, data collection and data analysis. Students are introduced to a range of lab and field techniques in physical and / or human geography along with statistical analysis. They gain experience in describing, interpreting and presenting the results.
GEG344 The Cryosphere in a Changing Climate

This module will provide you with the scientific basis to understand the physical behaviour of glacier ice in our changing climate. We will look at spatial scales ranging from individual ice crystals to continental-scale glaciation. The module core topics will include glacier mass balance, transformation of snow to ice, glacier hydrology, glacier dynamics, ice crystal structure and deformation, glacier sliding, deformation of glacial sediments, glacier flow instabilities and glacier surging. We will introduce example topics of current research interest. The module is assessed through examination, as well as group presentation on a seminar and a short individual report.
GEGM06B Geographic Information and Climate Change

This module offers the opportunity to undertake a major individual research project in the field of Environmental Dynamics and Climate Change/Geographic Information and Climate Change/Environmental Drone Remote Sensing. Support is provided by a staff supervisor and through GEGM06P (Dissertation Preparation Module). The Dissertation will be presented in the form of a scientific paper with supporting data.
GEGM06P Dissertation Preparation Module

This module introduces students to the MSc dissertation in Environmental Dynamics and Climate Change/Geographic Information and Climate Change/Environmental Drone Remote Sensing programmes. The module provides students with support in developing a research topic. Students are introduced to concepts of experimental design, research ethics, risk assessment, scientific writing, hypothesis testing and how to structure their dissertation. A laboratory induction and basic field skills will also be introduced. Students will be required to develop a topic for their dissertation and a plan for its realisation. Key milestones must be achieved throughout the module before students are permitted to start work on their dissertation research. Students who do not complete these milestones within the required timeframe and to a satisfactory standard will not be able to proceed directly to the dissertation module
GEGM07 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.
GEGM21 Climate Change - Past, Present and Future

This module will examine the Earth's climate system, and the principal natural and anthropogenic forcing mechanisms controlling it. The detection and nature of recent environmental changes will be discussed within the context of the Earth's climate history . The tools and methods used to measure, predict and study climate changes will be introduced. This will include the fundamental structure of General Circulation Models and how these techniques may be employed in conjunction with instrumental and proxy data to study the climate of the past and to reduce uncertainty in future climate change projections.
