Session 2019-20 Level 6 FHEQ Second Semester 15

Aims

To provide students with a view of the ocean carbon cycle as a dynamic system;
To give students an appreciation of the importance of chemical and biological processes in controlling the distribution of carbon in the ocean;
To provide students with an in depth understanding of the carbon cycle from the surface ocean, to the deep ocean and sediments, and the impact environmental change may have on it.


Learning Outcomes

(LO1) Students will learn how physical, chemical and biological process control the transfer of carbon between the atmosphere, ocean and land, and the distribution of carbon species between these environments

(LO2) Students will understand the role and significance that the ocean plays in the global cycling of carbon

(LO3) Students will understand the pathways involved in cycling of inorganic and organic carbon between land and the ocean and the surface and deep ocean, with emphasis on the solubility, carbonate and biological pumps

(LO4) Students will understand how stable isotopes can be used to study the carbon cycle and how it has varied in Earth's history

(LO5) Students will understand how environmental change is perturbing the global carbon cycle in the present day. Topics covered will include ocean acidification and changes in the surface temperature

(S1) Numeracy (application of) manipulation of numbers, general mathematical awareness and its application in practical contexts (e.g. measuring, weighing, estimating and applying formulae)

(S2) Problem solving/ critical thinking/ creativity analysing facts and situations and applying creative thinking to develop appropriate solutions.

(S3) Communication, listening and questioning, respecting others, contributing to discussions, influencing, presentations


Syllabus
