PL44A:
Climate Variability, Ocean Dynamics, and Biogeochemical Cycles in the Indian Ocean II Posters

Session ID#: 84734

Session Description:
Ocean circulation, climate and biogeochemistry are important components for climate change prediction. While climate variability can affect ocean circulation and biogeochemical processes, variations of ocean circulation and biogeochemical cycles can alter air-sea gas exchange, Earth’s energy balance and thereby affect climate. Together, climate and biogeochemistry have prominent impacts on biodiversity, coastal fisheries and human health, and are crucial for climate change mitigation and adaptation. Yet, our understanding of their associated processes in the Indian Ocean, where in situ observations are often lacking, is severely limited. Toward this end, the on-going 2nd international Indian Ocean Expedition (IIOE-2) is collecting invaluable new observational data in the Indian Ocean through 2025.

The session focuses on the Indian Ocean circulation, air-sea-land coupled processes and their interactions with biogeochemical processes, and will synthesize the latest observational and modelling efforts directed toward understanding physical processes associated with climate variability, climate change, variations in biogeochemical cycles, as well as their interactions. Papers are invited that address Indian Ocean variability on various timescales (from subseasonal to centennial) from the past into the future. Examples include phenomena such as MJO, IOD, decadal climate variability and climate change, changes in the carbon cycle and atmospheric aerosols, and others.
