PhD student in Marine Biology

Updated: 7 months ago
Deadline: 15 Mar 2023

Ref. No. SU FV-0411-23

at the Department of Ecology, Environment and Plant Sciences . Closing date: 15 March 2023.

Research and education at Stockholm University at the Department of Ecology, Environment and Plant Sciences (DEEP) is located in the Arrhenius Laboratories, situated at the University Campus at Frescati. Research carried spans across a broad range of biology subject areas including Ecology and Evolution, Ecotoxicology, Marine Biology, Plant Physiology and Plant Systematics. Presently around 110 people are working at DEEP using state-of-the art methodologies in an international research environment characterized by world-recognized researchers and a high level of professionalism.

Project description
The Department of Ecology, Environment and Plant Sciences invites applications for a four-year PhD position part of the project ‘The use of OLCI/Sentinel-3 and MSI/Sentinel-2 data for assessing the effect of climate change in coastal and inland waters’. 

Ocean colour research allows for a synoptic analysis of marine and inland waters. Besides assessing the spatial distribution and phenology of phytoplankton blooms it also allows for a deeper understanding of the physiochemical drivers (such as wind speed and light attenuation) of phytoplankton growth and production.  By combining MERIS data from the ESA ENVISAT program (2002-2012) and OLCI data (since 2016) from the Copernicus program (Sentinel-3 satellite) we can now derive long term time series of essential climate change variables for climate change analyses, especially when combined with other ocean colour data and/or in situ data as well.

Additionally, MSI data (from Sentinel-2 satellite), which has a better spatial resolution (10-60 m) than MERIS and OLCI (300 m), allows for improved monitoring of coastal and inland waters. The first part of the project will be on development and testing of algorithms and products, while the second part will be on how we can use these techniques for a better understanding of the effects of climate change on phytoplankton phenology in coastal and inland waters.

The PhD project is funded by the Swedish National Space Agency (SNSA) as part of the research project ‘The use of Copernicus Sentinel-3 data for research and societal needs’ and is therefore bound to the general objectives and deliverables of this research project. Demonstrated experience with the analysis of ocean colour data (e.g. BSc or Masters thesis) is a prerequisite for this position.

Qualification requirements
In order to meet the general entry requirements, the applicant must have completed a second-cycle degree, completed courses equivalent to at least 240 higher education credits, of which 60 credits must be in the second cycle, or have otherwise acquired equivalent knowledge in Sweden or elsewhere.

In order to meet the specific entry requirements, the general syllabus for doctoral studies in the field of Marine Biology stipulates, that applicants must have completed at least 60 higher education credits in the second cycle of which 15 credits must be from a course in Marine Biology, and 30 credits from a project in Marine Biology. Applicants may also have otherwise acquired equivalent knowledge (e.g. in biological oceanography or physical geography) in Sweden or elsewhere.

The qualification requirements must be met by the deadline for applications.

The criteria used in the selection for admittance to research training in Marine Biology are knowledge of theory and applications in the research field, knowledge with relevance for the research project; ability to communicate orally and in writing, knowledge of English, creativity, analytic competence, initiative, independence and collaboration ability.

The PhD student will be expected to help preparing and join research campaigns organized by the principal investigator. Experience of working on board a research vessel and with measuring optical properties of natural waters are a merit. A European driver’s license (category B) is important for conducting the field work safely. Furthermore, the position is not recommended for someone who is prone to seasickness, as this may be a hindrance to perform satellite validation work at sea.
