Unit Information

Why is this unit important?

The Geophysics 1 unit will give you the foundations in the fundamental concepts needed to succeed in your future study of Geophysics. Closely allied to this goal is developing your applied mathematical and problem-solving skills. The unit will include lectures and practical classes.

How does this unit fit into your programme of study

For the first part of the unit you will be taught alongside other Earth Science students, who have an A’ level in Mathematics (in common with Geophysicists). Additionally, you will then receive bespoke Geophysics teaching, just to your cohort of students. This bespoke teaching will introduce you to a range of topics of specific interest to you, as a Geophysicist. It will also help you get to know your fellow Geophysics students and staff in the School of Earth Sciences.

Your learning on this unit

An overview of content

  • data and uncertainties
  • quantities; units; dimensions; dimensional analysis
  • calculus: differentiation and integration
  • forces, flow and frames of reference (vectors and coordinate systems)
  • Earth as a rotating reference frame; the Coriolis force
  • Navier-Stokes equation and the equation of motion used in climate models
  • scalar and vector fields
  • vector calculus and applications
  • approximating functions (series approximations; Milankovitch cycles)
  • complex numbers; complex Fourier series
  • stress, strain and matrices (matrix algebra; linear algebra; simultaneous equations; least squares fitting using matrices; eigenvalues and eigenvectors; matrices describing simple shear, pure shear or rotations)
  • geophysical topics and their underpinning mathematics (topics may change annually)

How will students, personally, be different as a result of the unit?

You will advance from your A’ level standard of Mathematics and Physics to a University level of understanding. In particular, you will start to be able to use your high level of Mathematics in your study of Geophysics.

Learning Outcomes

  • Understanding and employing physical quantities, uncertainties and dimensions in the context of Earth Sciences
  • Understanding and applying calculus, vector and scalar fields and series summation in a variety of physical contexts. Applications include classical mechanics, fluid flows, and Earth’s rotation.
  • Appreciating and deploying matrix methods. Matrices will be used in solving simultaneous equations, and to consider the geophysical meaning of stress and strain.
  • Ability to apply mathematical and physical knowledge to problems in geophysics, for example employing methods utilising differential equations, complex numbers and series. The mathematical content will depend on the specific applications.

How you will learn

The unit is taught via a combination of lectures and weekly practicals that allow the students to practice and deepen their knowledge and skills. Demonstrators are on hand during practicals to help students who get stuck. All practicals also have worked solutions on BB and students are strongly encouraged to work through the worked solutions independently as it is an enormously useful learning opportunity in itself.

Additionally, students are provided with a range of resources that will help them to develop their understanding and skills and assess how well they are doing:

  1. formative tests (3 during the course of the unit + 1 ‘resit’ for students who did not do well in the first test)
  2. bank of ‘homework’ questions with worked solutions on BB
  3. a small amount of guided, structured reading (all provided on BB)
  4. online Office Hour
  5. Physics Discussion Board, where you can post questions and answers

How you will be assessed

Tasks which help you learn and prepare you for summative tasks (formative)

There will be 3 formative (~ 1 hour) tests during the course of the unit. These will be similar in style to the summative exam.

Tasks which count towards your unit mark (summative):

Summative exam, 3 hours, 100%. The exam will cover content from both the Physics and Geophysics elements.

When assessment does not go to plan

The University’s Regulations and Code of Practice for Taught Programmes outline the requirements for progression on and completion of degree programmes. Students who miss an exam and self-certify their absence may complete a supplementary assessment for an uncapped mark as if taken for the first time. Resit and supplementary exams are habitually taken during the reassessment period later in the summer. As far as is practicable and appropriate, resit and supplementary assessments will be in the same form as the original assessment but will always test the same intended learning outcomes as the initial missed or failed assessment. In the case of group work, failure by a whole group would result in an appropriate group task being set and reassessed for all group members. If a single student fails a group assessment or is unable to participate for an evidenced reason, an individual reassessment will be set.

There are rigorous and fair procedures in place to support students who are ill or whose studies and assessments are affected by exceptional circumstances.

Resources

If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.

If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. EASC10009).

How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours of study to complete. Your total learning time is made up of contact time, directed learning tasks, independent learning and assessment activity.

See the Faculty workload statement relating to this unit for more information.

Assessment
The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit. The Board considers each student's outcomes across all the units which contribute to each year's programme of study. If you have self-certificated your absence from an assessment, you will normally be required to complete it the next time it runs (this is usually in the next assessment period).
The Board of Examiners will take into account any extenuating circumstances and operates within the Regulations and Code of Practice for Taught Programmes.
