KE6030 - Geophysical Dynamics

What will I learn on this module?

In this module you will learn basics concepts of continuum mechanics i.e. kinematics (material derivatives, kinematic boundary conditions), kinetics (stresses, traction), balance laws (mass, momentum, energy) and constitutive relationships (stress strain relationships for fluids).

You will learn the effects of rotation on the fluid flow and how these affect the large-scale flow of the ocean and the atmosphere. The focus is on understanding how the large-scale flow regime of the ocean, atmosphere, glaciers and the mantle can be described mathematically.

Your learning will be set within the context of global environmental changes. The module will provide you with the tool required to understand the physical principles of global circulations models used to describe the movement of the atmosphere, oceans, earth’s mantle and large ice sheets.

The course consists of lectures and exercises using a state-of-the art numerical ice sheet model. Assessment of the module is by one individual numerical modelling assignment (30%) and one formal examination (70%).

On completion of the module you will have developed an improved understanding of the earth system and the principles of climate change.
The module is designed to provide you with a useful preparation for employment in earth sciences with aim at pursuing graduate studies in environmental modelling.

Outline Syllabus

• Introduction and review of continuum mechanics, balance laws (mass, conservation, energy), kinematics of deforming bodies, constitutive laws (non-Newtonian rheology).

• Rotating shallow-water models. Large-scale flow approximations used in earth sciences. Large-scale features of ocean circulation and atmospheric circulation. Ocean gyres, boundary currents, eddy transport. Variation in flow with depth/height. Geostrophic balance. Ekman spiral.

• Hydrostasy in the ocean and atmosphere.

• Mechanics of glaciers and ice sheets. Commonly used flow approximations in glaciology. Ice-sheet instabilities. Grounding-line dynamics and instabilities.

• Scaling of flow equations and linearization. Systematic reduction of equations.

How will I learn on this module?

The module will be taught using a combination of lectures and computer lab sessions. Lectures will provide you with a systematic overview of geophysical dynamics. You will learn the fundamental equations of continuum mechanics describing large-scale geophysical flows. Computer lab sessions involve the use of a large-scale ice sheet model written in matlab. Students have an opportunity to tailor their computer projects toward their own interested and will be expected to demonstrate ability to work independently.

Students will be assessed by coursework (30%) and a formal examination (70%). The examination will cover all topics from the module.

How will I be supported academically on this module?

Lectures introduce the key topics of the module. Further understanding will be gained through exercises and by running a large-scale geophysical numerical models.

In addition to direct contact with the module team during lectures and lab sessions, students will encouraged to work independently on a project and further develop their curiosity by making direct contact with the module team either via email or the open door policy operated throughout the programme. Students will also be regularly referred to supporting resources including relevant texts and relevant multimedia materials.

Regular feedback on your learning progress will be provided. This will primarily take place during lectures in informal Q&A sessions.
References to these resources will be made available through the e-learning portal in lectures and computer lab sessions.

Summative assessment consists of an assignment on project work and a computer based formal examination.

Informal feedback will be provided on computer lab session based on problems designed to aid student understanding.
Feedback is provided to students individually and in a plenary format both written and verbally to help students improve and promote dialogue around the assessment.





Module abstract

This module introduces the physical concepts governing various geophysical flows and deformation regimes. These include the large-scale flows of the atmosphere and the oceans, ice-sheets and glaciers, and mantle dynamics. The focus is on understanding how continuum mechanics provide a general framework for understanding various large-scale geophysical flow phenomena. The module is designed to provide students with the mathematical and physical tools required to understand `how the earth works’, and in particular to provide students with the background needed to conduct research in earth sciences involving modelling of ice-sheets, the oceans and the climate system.

Assessment of the module is by one individual assignment related to numerical modelling project (30%) and one formal examination (70%). The module is designed to provide students with a useful preparation for employment or postgraduate study in an applied mathematical or engineering environment.

Module Information

All information on this course page is accurate at the time of viewing.

Courses starting in 2021 are offered as a mix of online and face to face teaching due to the ongoing Covid-19 pandemic.

We continue to monitor government and local authority guidance in relation to Covid-19 and we are ready and able to flex accordingly to ensure the health and safety of our students and staff.

Students will be required to attend campus as far as restrictions allow. Contact time will increase as restrictions ease, or decrease, potentially to a full online offer, should restrictions increase.

Our online activity will be delivered through Blackboard Ultra, enabling collaboration, connection and engagement with materials and people.
