Biogenic emission by microalgae from the maritime continent
This project aims to measure the halocarbon production and identify the microalgae producing them in the field during a voyage on the RV Investigator while travelling through the region known as the Maritime Continent. This area comprises the islands and seas of Indonesia, Malaysia, New Guinea and surrounds. This experiment is part of a large international team that aims to improve the climate models in this region, which has a great influence on Australia’s climate. The biogenic emissions from microalgae play a role in cloud formation and will be used to improve the chemistry-climate models in the region.
This multidisciplinary project intersects two of Deakin’s School of Life and Environmental Sciences strengths in Marine and Chemistry research and will involve voyage time on the RV investigator. We are seeking a dynamic, intelligent, highly motivated PhD student to work on the project that will be developed further with input from the successful applicant. The successful candidate will be working under the direct supervision of Dr Damien Callahan, Deakin University and Dr Robyn Schofield The University of Melbourne. Specific aims for the project are:
Aim 1: To develop on-board algal identification and culturing techniques as well as the installation of a portable GC-ECD for the detection of halocarbon emissions while under way.
Aim 2: To quantify halocarbon production in the Maritime continent and identify the microalgal species responsible for their production. The voyage will take place between Oct-Dec 2019. During the voyage real time air sampling and water sampling will take place.
Aim 3: To isolate unicellular algal cultures for further laboratory studies of biogenic emissions from these cultures and to improve our understanding of how different environmental factors effect emission of halocarbons.
Aim 4: Carry out a detailed analysis of the collected samples using metagenomics.
Both International and Australian applicant are welcome to apply. The candidate must have a First Class Honours Degree or Master’s Degree with a major in analytical or marine chemistry or marine botany.
