Overview

This module provides experience of multidisciplinary fieldwork at sea.

A wide range of oceanographic and geophysical instrumentation is introduced including instruments for measuring salinity, temperature, currents, chlorophyll, suspended and sea bed sediments. These include CTD, optical instruments (transmissometer, fluorometer), and instruments for measuring current (acoustic Doppler current profiler). In addition sampling of plankton, suspended and seabed sediments will be covered.

Students spend one full day at sea on a research vessel, collecting data using on-board instrumentation and collecting samples from the water column and sea bed.

These are combined with data collected by students on other days (at least 12 in total, depending on numbers taking module) to produce an extensive database. This data is used to explore physical, geological, and biological processes in detail, including the relationship between disciplines.

Assessment Strategy

-threshold - D grade - Basic understanding of theory and application of oceanographic instrumentationBasic understanding of oceanographic and plankton sampling

-good - B grade - Comprehensive knowledge of the theory and application of oceanographic instrumentationComprehensive understanding of oceanographic and plankton samplingShow a clear understanding of how empirical data relate to theoryFull competence in the use of post-processing techniquesManipulation of data to answer questions relating to observed spatial and temporal variability

-excellent - A grade - Construct a relevant discussion of discrepancies between theory and observationsExpertise in post-processing, data analysis and presentationUnderstanding the limitations of the data collected and how observations might be improved

Learning Outcomes

• Analyse samples and data and draw appropriate conclusions

• Appreciate the contributions of other scientific disciplines to their own specialised field

• Collect samples and record data from the water column and sediment

• Communicate their findings

• Demonstrate a wide knowledge of both the principle of operation and methods of use of a wide range of oceanographic instruments

• Process and synthesise large and complex datasets

• Understand the practical difficulties associated with making direct measurements in the marine environment, and how to overcome these
