About Ron Lindsay
I am interested in how the sea ice in both polar regions moves, grows, and decays in response to changing environmental conditions and how the changes in the ice pack is impacting the atmosphere above. To pursue these research themes I use a wide variety of in situ and remote sensing data and numerical models. In situ data is from ice camps, buoys, submarines, and moorings, while remote sensing data is from many different sensors: e.g. AVHRR, MODIS, SSMI, AMSR, and SAR. The last, Synthetic Aperture Radar, is the basis for highly detailed measurements of ice movement and deformation. I have developed a unique Lagrangian model of the ice pack that is capable of assimilating the SAR ice motion data. I have also conducted extensive analyses of the output of the retrospective Polar Science Center Eulerian model to determine how, where, and why the ice pack is rapidly changing. The Eulerian model is also the basis for a statistical predictive scheme I have developed for forecasting the ice extent months in advance, either for the Arctic as a whole of for specific regions. Finally, I am developing a capability for modeling the response of the atmosphere to changing pack ice conditions in order to understand the extent to which the heat absorbed in the open water areas in the summer slows the growth of ice in the winter. |
