SICSS doctoral student wins European Geosciences Union Poster Award

04.09.2011

Bente Tiedje won this year´s "Outstanding Student Poster Award 2011" presented by the Ocean Sciences Division of the European Geosciences Union (EGU) with a poster on the potential predictability of heat transport in the North Atlantic. Bente Tiedje works as a doctoral student in the CliSAP Research Group on "Data Assimilation in the Climate System" headed by Junior Professor Johanna Baehr.

With the help of model calculations, Bente Tiedje figures out why, where and for how long potential predictions are possible. She presented the results to the EGU members on her poster. "The award was a big surprise," Tiedje says. "The EGU General Meeting was held more than four months ago. But naturally, I´m thrilled to have won!"

In her project Bente Tiedje found out that processes that determine the potential predictability of heat transport are contingent on the geographic latitude. Predictability in sub-tropical latitudes (15-35°N) is thus mainly determined by variations in the flow velocity. In sub-polar latitudes (45-55 °N) on the other hand, it is mainly variations in temperature that have an impact.

The young oceanographer has in the meantime made progress in her research. "Some of the information currently shown on the poster has already been qualified," explains Tiedje, "because we have meanwhile changed the experimental setup. We have also included new dimensions which in some cases result in different conclusions."

The EGU "Outstanding Student Poster Award" is presented to Masters and PhD students and to young university graduates every year.
