The 2017 Outstanding Student Poster and PICO (OSPP) Award is awarded to Svenja Ryan for the poster/PICO entitled:

I am a PhD student at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research in Bremerhaven, Germany. My study area is the southwestern Weddell Sea where the ocean interacts with the Filchner Ronne Ice Shelf (FRIS), which is by volume the larges ice shelf in Antarctica. My research focuses on the seasonal and interannual variability in the flow of Warm Deep Water (WDW), a derivative of Circumpolar Deep Water, onto the continental shelf along the eastern flank of the Filchner trough. Models predict an increases WDW flow towards FRIS in the future climate. The poster presents a so far unknown seasonal cycle in hydrography derived from three two-year long mooring time series. It can be divided in four distinct phases, which show a seasonal inflow of WDW but a flow reversal in winter, when the shelf is weakly stratified.
