GEOG3817: ANTARCTIC ENVIRONMENTS

Prerequisites

• Any Level 2 Geography Module

Corequisites

• None

Excluded Combination of Modules

• None

Aims

• This module examines the physical and biological environments of Antarctica, and their potential for change. Special emphasis is given to the continent's role in global systems and the unique way it is studied and administered.

Content

• Part I – Present Environments
• Antarctica: a 'continent for science' - role in global climate, sea ice, formation of ice sheet, circumpolar current + vortex, polar amplification of climate change, baseline lab, S ocean food chains, global sea level
• The physical environment and ecosystems- climatology, oceanography, ice sheet, sea ice formation, geology, glaciology, ecosystems
• Part II – Environmental Change
• Long-term Environmental history - geological history, ice sheet history, Holocene change
• Climate change -measured change, long-term trends vs anthropogenic impacts, physical impacts: sea ice, ice shelves, ice sheet, impacts on sea level, ocean currents, collapse of WAIS, Case Study I: Antarctic Peninsula temp record; Case Study II: Peninsula ice shelves
• Ozone depletion and Pollution: ozone hole (background and measurement), biological impacts of ozone depletion (marine and terrestrial), temp. change (marine and terrestrial), spread of communities, problem of thresholds, baseline measurements, ice cores, rubbish around stations, oil spills, robust or sensitive. Case Study: the Bahia Paraiso spill
• Part III – The Human and Political Dimension
• Antarctic resources - geological/mineral, biological, impacts of exploitation - Case study: Southern Ocean fisheries
• A Treaty for the 21st Century: the legislative framework. Tthe importance of the Antarctic Treaty in the history of Antarctica, how it works: the key sections (science, territorial claims, fisheries, mining), environmental management in Antarctica
• The future of Antarctica......(Tutorial session) - pollution, ozone, possibility of WAIS collapse, mining, will the Treaty hold, lessons to be learned from Antarctica Case study: risk estimation of WAIS collapse

Learning Outcomes

• On successful completion of this module students are expected to be able to:
• Understand the present-day physical and biological environments of Antarctica
• Demonstrate a detailed knowledge and understanding of a number of case studies of Antarctic environmental change, and be able to explain the causes and importance of long- and short-term environmental change in Antarctica
• Understand the unique way that Antarctica is administered and the history and style of human impacts on Antarctica

• On successful completion of the module students are expected to be able to:
• Assess the human/physical interface through emphasis on issues surrounding future environmental change in Antarctica, and how this may affect global systems (including climate, sea-level)
• Comprehend the nature of variability in the nature and quality of field data, particularly acute in Antarctica, and relate their lecture-based material and reading to real-world contexts

• On successful completion of the module students are expected to be able to:
• To present critical evaluation of the academic literature on Antarctic environments and environmental change
• To discuss current issues surrounding the management of Antarctica and Antarctic Environments

Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

• The module will be primarily lecture-based. These lectures will focus on the first three learning outcomes, and will, of course be supplemented by extensive recommended reading of the academic literature. There will also be a tutorial where there is an opportunity to debate some of the unique issues associated with managing the continent and through this develop a deeper understanding of these issues. Students ability to interpret and apply both theoretical concepts and practical management issues specific to Antarctica will be tested via the exam.
• Note on timing: the module will start in Term 1 but there will be a pause in lecture-based content between late Term 1 and mid-Term 2 (whilst Prof Bentley is on Antarctic fieldwork). During the hiatus in lectures students will undertake the formative project (see below).

Teaching Methods and Learning Hours

Summative Assessment

Formative Assessment:

Mini-project on current trends of EITHER sea-ice extent OR Ozone concentrations. This will entail using online datasets to assess the changes in sea-ice/ozone during this Antarctic spring and summer, and to put changes in context with recent trends (Max. 2 pages in accordance with Departmental Policy on Coursework Length and Format). Formative feedback will be given on proposal.

■ Attendance at all activities marked with this symbol will be monitored. Students who fail to attend these activities, or to complete the summative or formative assessment specified above, will be subject to the procedures defined in the University's General Regulation V, and may be required to leave the University
