Description - summary of the module content

Module description

Biological Oceanography takes a view on life in our oceans from bottom upwards. Focusing on microorganisms (phyto- and zoo-plankton) at the base of the food chain, that reside in the photic zone, this module looks at how the ocean’s physical and chemical environment shapes plankton diversity, productivity, and distribution, at global, seasonal and longer time scales. It investigates the role of plankton in the food chain and in ocean biogeochemical cycles. Techniques used to monitor plankton in the laboratory, in situ, from satellite and robotic platforms, are reviewed, and used with mathematical modelling to help understand plankton ecology and how plankton may respond to a changing ocean. The module is linked to broader environmental science topics (e.g. climate change, biogeography, biodiversity and ocean health) taught in the programme. There are no pre-requisites, but it would be useful to have undertaken ocean-based modules (e.g. GEO2428B Atmosphere and Ocean Systems) in your second year.

Module aims - intentions of the module

Ocean biology regulates our climate, is responsible for half the oxygen in the atmosphere and is an importance resource of food and energy. It has been described as the planet’s life support system. This module aims to provide you with a background in biological oceanography. You will develop an understanding of how ocean biology is shaped by the physical and chemical environment and influences it through feedback loops. The module explores the distribution and diversity of phytoplankton and zooplankton, and how these organisms modulate marine biogeochemical cycles, the marine food web and even the climate. It takes a look at marine biogeography, how plankton influence the ocean carbon cycle and how plankton are responding to climate change.

There will be a large emphasis in the module on the tools used by scientists to understand biological oceanography, specifically modern satellite-based and robotic platforms and sensors, as well as traditional ship and lab-based techniques, and even historic methods dating back to the 19th Century. Basic numerical modelling will also be used to explore and help explain the interactions between plankton and their environment. The module content will draw on research undertaken by the module convenor, including examples from recent research into: the ocean biological carbon pump, satellite remote-sensing of ocean colour, basin scale distributions in phytoplankton composition, and long-term (interannual and decadal) changes in phytoplankton, in response to a changing climate.

Through a series of lectures, online activities and practical sessions you will develop the following graduate attributes relevant to future employment: computer modelling (ocean ecology); satellite remote sensing (ocean colour); data presentation; report writing skills; task management; time management; and general analytical skills.

Intended Learning Outcomes (ILOs)

ILO: Module-specific skills

On successfully completing the module you will be able to...

  • 1. Discuss and understand the physical, biological and chemical controls on phytoplankton abundance in the ocean
  • 2. Describe the distributions of phytoplankton in the ocean, both spatially (vertical and horizontal) and temporally (seasonally)
  • 3. Summarise comprehensively the processes of primary production, secondary production, and recycling, and the influence these processes have on the transfer of energy through the marine food web
  • 4. Review the advantages and disadvantages of the major tool and techniques (both modern and historical) used in biological oceanography

ILO: Discipline-specific skills

On successfully completing the module you will be able to...

  • 5. Describe in detail and analyse essential facts and theory across a sub-discipline of environmental science
  • 6. Analyse and evaluate independently a range of research-informed literature and synthesise research-informed examples from the literature into written work
  • 7. Identify and implement, with limited guidance, appropriate methodologies and theories for solving a range of complex problems within environmental science
  • 8. Describe and evaluate in detail approaches to our understanding of geography with reference to primary literature, reviews and research articles

ILO: Personal and key skills

On successfully completing the module you will be able to...

Re-assessment notes

Deferral – if you miss an assessment for certified reasons judged acceptable by the Mitigation Committee, you will normally be either deferred in the assessment or an extension may be granted. The mark given for a re-assessment taken as a result of deferral will not be capped and will be treated as it would be if it were your first attempt at the assessment.

Referral – if you have failed the module overall (i.e. a final overall module mark of less than 40%) you will be required to complete an additional Essay and Practical Report. The mark given for a re-assessment taken as a result of referral will be capped at 40%.
