Second IOCCG Summer Lecture Series

Applications are now open for the Second IOCCG Summer Lecture Series, which will take place in Villefranche-sur-Mer, France from 21 July to 2 August 2014. This course is dedicated to high-level training in the fundamentals of ocean optics, bio-optics and ocean colour remote sensing. A number of distinguished scientists have been invited to provide lectures on cutting edge research, focusing on current critical issues in ocean colour science. Students will be given ample opportunity to meet with the lecturers for in-depth discussions on various pre-selected topics, as well as their own scientific research. As was done for the past Summer Lecture Series, all the lectures will be video recorded and made available online. These recorded lectures are a valuable training resource and have been downloaded thousands of times by students from around the world.

Further information about the course, as well as the application forms, can be found at: www.ioccg.org/training/SLS_2014.html. The deadline for applications is 14 March 2014.

Analysis of phytoplankton functional types in the Gulf of Lions from satellite data and study of their influence on spatio-temporal dynamics of small pelagic fish

Throughout the world, small pelagic fish stocks are known to fluctuate a lot. Yet, the mechanisms responsible for the important spatio-temporal variability in these stocks remain mostly unknown. Environment is often supposed to be the main driver of small pelagic dynamics, thus assuming a bottom-up control of their populations. This project aims at testing this hypothesis by evaluating the potential link between plankton and small pelagics in the North-West Mediterranean Sea (NWMS). The first step will be to assess the phytoplankton composition of the NWMS since 1997 using PhySat algorithm based on ocean colour satellite data. The study of its spatio-temporal distribution through geostatistics and wavelet analyses should yield important insights on potential changes or shifts in plankton community composition during the last 15 years. Then, the link between phytoplankton spatio-temporal distribution and abiotic conditions (such as temperature, meso-scale dynamics) will be investigated. The final step of this project will be to test the main hypothesis of a bottom-up control of small pelagic fish by comparing the phytoplankton production datasets and those of abundance, biomass and condition indices of small pelagics obtained since 1993.

Keywordsphytoplankton, remote sensing, functional type, bottom-up process, optic reflectance, Physat, environmental effects, spatial dynamics.

Qualifications:

We are looking for a highly motivated candidate in possession of a PhD in marine biology, oceanography or fisheries science. Skills in scientific computation and modelisation are necessary, as well as in remote sensing data manipulation. A good knowledge of plankton would also be highly appreciated. Finally, a good level of English writing is expected.
