Sorbonne Université is inviting applications for a 2-year postdoctoral 
research position to dynamical processes associated with dense water 
formation in the Southern Ocean.


The successful applicant will investigate water-mass formation and 
transformation in the coastal polynyas distributed on the Antarctica 
continental shelves. The work will be based on a range of observations 
including instrumented seals, which regularly sample water-masses in 
coastal polynyas. Polynyas will be detected using satellite and 
atmospheric reanalysis observations based on a method developed by 
Labrousse et al. (2018), in close coordination with Sara Labrousse 
(WHOI). The study will extend work that we develop to understand 
large-scale water-mass formation around the Southern Ocean (Pellichero 
et al., 2018), in which we demonstrated that existing under sea-ice 
observation databases allow to quantify water-mass transformation 
associated with sea-ice and atmospheric processes. The ultimate goal is 
to isolate and assess the global impact of polynyas on large-scale 
water-mass transformation, and their overall impact on the overturning 
circulation by producing dense water-masses on antarctica continental 
shelf. Depending on the advance of the project, and the motivation of 
the successful candidate, overflow of dense shelf water (produced in the 
polynyas) on the continental slope toward the Southern Ocean abysses 
might be investigated using autonomous deep floats we deployed in East 
Antarctica and in the Weddell Sea as part of the WAPITI project.

The project is exploratory and will start by assessing what can be 
obtained given the available dataset, before digging in the dataset, to 
extract relevant information for our understanding of ocean circulation 
and climate. We particularly seek a researcher with an interest in and 
talent in ocean observation analysis and ability in dealing with large 
and diverse sources of ocean observation to develop deeper dynamical 
understanding of ocean circulation and climate. The researcher will join 
a team of scientists at LOCEAN-IPSL in Paris (J.B. Sallee; C. de 
Lavergne; J-B Charrassin) and will strongly collaborate with phD and 
other postdoc working on the WAPITI project, as well as external 
collaborators based at WHOI (S. Labrousse) and Australia (CSIRO, IMAS).
