SOES1012 Physics and Dynamics for Oceanography

Module Overview

This module provides the fundamental physics needed for marine science, and enables students to apply fundamental statistics methods in an oceanographic context.

Aims and Objectives

Module Aims

1) To introduce the basic principles of physics that are required in future modules, and demonstrate how the understanding of these principles is essential for the understanding of the motion of the ocean and atmosphere, as well as particles and organisms in seawater. 2) To provide experience of using these physical principles to solve problems in oceanography. 3) To introduce dynamical principles in oceanography. 4) To develop confidence at quantitative tasks.

Learning Outcomes

Learning Outcomes

Having successfully completed this module you will be able to:

  • Describe, and write down equations for: - Newton's laws of motion - Circular motion and conservation of angular momentum - Conservation of energy
  • Write down and explain the Navier-Stokes equations, identifying contexts in which the following terms are important: - Net acceleration - Acceleration due to gravity - Acceleration due to the pressure-gradient force - Acceleration due to the shear stress (frictional) force - Acceleration due to the Coriolis force
  • Qualitatively predict the motion of seawater and particles, under scenarios comparable to those encountered in the ocean, based on the above physical principles
  • Identify instances when turbulence may arise in oceanographic settings.
  • Explain the concept of dynamical diffusivity and apply this to solve problems in an oceanographic setting.
  • Solve quantitative problems in marine science based on physical and statistical principles.
