Oceanic and atmospheric controls on decadal melt variability in the Amundsen Sea

If you have a question about this talk, please contact Dr. Shenjie Zhou .

Ice shelves around the Amundsen Sea have been losing mass rapidly in recent years. Ocean warming is an important driver, as ocean temperature and basal melt show strong decadal variability, related to changes in the influx of warm circumpolar deep water on the shelf. The output of an ensemble of 20 ice-ocean simulations for the period of 1920-2013 is used to study temporal variability in melt and to delve into the associated oceanic dynamics, wind patterns and tropical variability. This shows a strong relationship between flow through troughs in the seabed and melt, but the relationship with the wind is not as clear as previous studies indicated. Special attention is given to the 1940s El Nino event, which is hypothesized to have led to the retreat of ice shelves in the region.
