Marine Biogeochemistry QMS512

Start and finish dates may change subject to staff availability, refer to the QMS website for further details. http://www.imas.utas.edu.au/qms/qms-unit-information.

QMS units are designed for postgraduate students with a strong background in quantitative analysis, mathematics, physics and chemistry.

Introduction

Biogeochemistry describes the cycling of carbon, nitrogen, sulfur and much more through the Earth system. Marine biogeochemistry is a relatively young science which over the past 50 years has grown from the application of chemical analyses of environmental samples to problems of material transports and transformation, to now encompass the influence of these chemical processes on the biosphere and conversely the influence of biological processes on chemical distributions. The overall field is very broad, ranging from questions such as the origin and possible extraction of important resources from seawater (e.g. rare earth elements, gold or uranium) to the impact of new substrates such as plastics on water quality. In this brief introductory unit, we focus on just one small subset of the field – the interactions of ocean productivity and biogeochemical processes with climate processes at the global scale, with a particular focus on oceanic control of the greenhouse gas carbon dioxide and the incorporation of these processes in the next generation of Earth system models.

Note

Please check that your computer meets the minimum System Requirements if you are attending via Distance/Off-Campus.

Units are offered in attending mode unless otherwise indicated (that is attendance is required at the campus identified). A unit identified as offered by distance, that is there is no requirement for attendance, is identified with a nominal enrolment campus. A unit offered to both attending students and by distance from the same campus is identified as having both modes of study.

* The Final WW Date is the final date from which you can withdraw from the unit without academic penalty, however you will still incur a financial liability (refer to How do I withdraw from a unit? for more information).

Unit census dates currently displaying for 2024 are indicative and subject to change. Finalised census dates for 2024 will be available from the 1st October 2023. Note census date cutoff is 11.59pm AEST (AEDT during October to March).

About Census Dates

Learning Outcomes

  • Describe the distribution of carbon and nutrients in the ocean and the processes that generate these distributions
  • Describe the interactions between physics, chemistry and biology that determine biological productivity in the oceans.
  • Obtain and manipulate ocean biogeochemical data to improve an understanding of biogeochemical processes.
  • Describe how isotopes are measured and used to quantify biogeochemical cycles and processes.
  • Explain the process of constructing a biogeochemical ocean model to inform its operation and limitation.

Teaching

Teaching Pattern

This is an intensive unit taught over 5 days. There are lectures for 3 hours in the morning and then computer based practicals in the afternoons. Students are required to attend all lectures and laboratory sessions. A student who fails to attend at least 80% of the lectures and laboratory sessions will, unless there are extenuating (e.g., medical) circumstances, be ineligible to pass the unit
