`ICE CORES HOLD CLUES TOMONSOON CHANGES'
The main objective of studying monsoon at the National Centre for Antarctic and Ocean Research (ncaor) is to understand how it has evolved over a long period of time. Atmospheric study helps us determine short-term changes
in monsoon patterns, Work at the Centre for Atmospheric and Oceanic Sciences (caos) broadly revolves around the monsoon but is not limited to it. We monitor the atmosphere and oceans at different scales, ranging from cloud covers to climate change. We also try to understand intra-seasonal and inter-annual variability of monsoons and the impact of aerosols and oceans on them. This is because physical processes on the ocean surface are very different from the physical mechanisms at deeper layers.
We are part of the Ocean Mixing and Monsoon (omm) programme along with several other Indian and American institutions,through which we hope to learn why the Bay of Bengal has a persistent shallow, fresh layer in spite of mixing by winds, waves and tides; and to understand how this layer affects ocean thermodynamics,air-sea fluxes and air-sea in-
