CODE PHY3212

 
TITLE Science of the Ocean Floor

 
LEVEL 03 - Years 2, 3, 4 in Modular Undergraduate Course

 
ECTS CREDITS 2

 
DEPARTMENT Geosciences

 
DESCRIPTION This study-unit will first provide a background to Earth and its geological system. Secondly it will focus on seafloor topographic elements and processes at a global scale, explaining the development of continental and ocean margins and basins, and the tectonic, sedimentary and oceanographic processes associated with both continental margins and ocean basins. Thirdly it will focus on seafloor features and processes at a fine spatial scale, exploring how these change from the near shore (e.g. submerged palaeolandscapes, continental shelves, fluid flow processes), to the continental slope (e.g. submarine landslides, submarine canyons, contourites etc.), and finally to the deep sea (e.g. submarine channels and fans, hydrothermal vents, seamounts and volcanoes). We will conclude the unit by reviewing the seafloor forms and processes around the Maltese Islands and in the surrounding central Mediterranean region.

Study-unit Aims:

- To give a broad outline of the origin, structure and evolution of ocean basins and continental margins.
- To equip students with an understanding of the nature and spatio-temporal scale of the principal seafloor processes and their signatures in seafloor data.
- To explain the environmental, social and economic implications of seafloor investigations, with particular reference to the central Mediterranean region.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will:
- Have a solid grounding in the physics of seafloor processes.
- Be able to appreciate the scale and complexity of seafloor processes.
- Be able to describe seafloor features found in different settings and understand the processes leading to their formation.
- Be able to understand the framework provided by plate tectonics, and the significant role played by climate and sea-level changes, in shaping the seafloor record.
- Be aware of the fundamental research questions that still need to be addressed in marine science.
- Be aware of the key seafloor forms and processes of the central Mediterranean region.

2. Skills:

By the end of the study-unit the student will be able to:
- identify seafloor forms from seafloor data.
- explain the sedimentary, structural and oceanographic processes responsible for a variety of seafloor forms.
- know which tools are used to investigate different seafloor forms and processes • To work in a team to solve a geoscientific problem.
- reconstruct geoscientific knowledge in written reports.
