Extreme Marine Habitats
Run by School of Ocean Sciences
20 Credits or 10 ECTS Credits
Organiser: Dr Laura Grange
Overall aims and purpose
The vast array of habitats found within the Earth's oceans is central to a wide diversity of life. Amongst them are the Polar Regions of the Arctic and Antarctic where temperatures plummet, corals reefs that represent some of the densest and most diverse habitats in the ocean, deep-sea habitats that exist thousands of meters from the surface, and deep-sea reducing habitats that thrive on reduced chemicals and the unique metabolic processes of microbial communities. In this module, we will focus on a range of different extreme marine habitats, introducing the physiologically challenging conditions that determine the abundance, distribution patterns and ecology of the marine organisms that live there.
This module will: - Explain why no extreme habitat is extreme to the organisms that live there. - Introduce a range of extreme habitats including the Polar Regions, coral reefs, the deep sea and deep-sea reducing habitats such as hydrothermal vents and cold seeps. - Examine the physiological and morphological adaptations that organisms have undergone to fully exploit each extreme habitat.
This module will consider the environmental and physiological factors that determine the abundance, distribution patterns and ecology of marine organisms in a range of extreme marine habitats. The habitats covered are: the Polar Regions, coral reefs, deep-sea habitats, and deep-sea reducing habitats such as hydrothermal vents and cold seeps. How the organisms have managed to adapt physiologically within these environments will be discussed and you will be shown the similarities and differences between these habitats and those considered less extreme.
Knowledge and basic understanding reliant entirely on the taught programme. Basic understanding of subject-specific theories, concepts and principles. Presents a competent overview of an extreme habitat in their assessment.
Wider knowledge and moderate understanding based on the taught programme, but with evidence of enquiry beyond that. Understanding of subject-specific theories, concepts and principles and some understanding of specialist areas. Presents a detailed, well researched and illustrated assessment showing clear understanding of the topic and questions posed
A very wide knowledge base extending well beyond the directly taught programme showing an in-depth understanding of the concepts presented. Thorough understanding of subject-specific theories, concepts and principles and in-depth understanding of more specialist areas. Presents an insightful, carefully argued, illustrated assessment showing clear evidence of independent thought.
By the end of this module, you should be able to:
- Outline the environmental and biological factors controlling the abundance, distribution patterns and ecology of organisms in extreme marine habitats in the oceans.
- Summarise how organisms are able to cope with the physiological demands of their extreme marine habitat.
- Using examples from the lecture material and peer-reviewed literature, question the concept of extreme marine habitats and consider whether these habitats are in reality extreme for the organisms that live there (now and in the future).
- Considering the key characteristics and concepts that are unique to extreme marine habitats and/ or organisms, present a case study in a way that is engaging yet rigorous in its scientific content and accessible to a general audience.
- Critically appraise a variety of evidence to inform your knowledge of extreme marine habitats and organisms, and make recommendations relevant to enhancing the accessibility of the information and your knowledge in light of your synthesis of appraised evidence.
