  • Geochemistry of climate proxies
  • Anthropogenic global warming: real or imagined?

Learning Outcomes

Subject-specific Knowledge:
  • To be able to describe the various components of the hydrological cycle.
  • Apply various empirical equations to estimate evaporation using appropriate meteorological data.
  • Apply a unit hydrograph to net rainfall data to forecast a stormflow event.
  • Apply a soil water accounting procedure to estimate actual evaporation from potential evaporation.
  • Predict groundwater flow rates using Darcy’s law.
  • Predict well production rates using the Theim equation.
  • Describe, compare and contrast various methods for measuring in situ moisture content and pressure head.
  • Estimate an advective travel time.
  • Describe and apply a simple steady state decay and sorption model.
  • Describe major events in the Earth's climate evolution and relate them to variations in the climatic feedbacks.
  • Describe how chronologies for geochemical proxy records of climate are developed.
  • Critically evaluate the precision and accuracy of a chronology around which a proxy record is developed.
  • Evaluate how variations in modern geochemical systems could result in climate change.
  • Critically evaluate modern, anthropogenic global warming.
  • Will have acquired the ability to judge the validity of various climate proxy records.
  • To describe the applications of various climate proxies.
  • To be able to apply the principles of geochemistry to quantitative problem solving.
  • To understand the uses of elemental and isotopic chemistry in Earth Sciences.
Subject-specific Skills:
  • Will have acquired intellectual and practical skills in order to apply hydrological and geological principles and methodologies to the solution of familiar and unfamiliar problems.
Key Skills:
  • Prepare, process, interpret and present data using appropriate qualitative and quantitative methods.
  • Solve numerical problems using computer or non-computer techniques.

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

  • The module is delivered through a mix of one-hour lectures and two-hour practical slots, supported by handouts and directed reading.
  • The practicals form an important component of the module allowing "hands on" learning and experience.
  • An unseen written exam will provide a test of the students understanding of supporting theory.
  • Summative assessment is made up of two practical assessments.
  • Guidance on preparation, key and exam skills are provided.
