Variability and controls of ocean climate revealed by long-term multidisciplinary eulerian observatories
Session ID#: 161276
Session Description:
The global ocean absorbs, stores, and redistributes vast amounts of heat and carbon and is therefore the main driver of climate regulation. It means that human-induced forcing is superimposed on ocean natural variability, and that this variable forcing involves complex interactions and feedbacks of physical, chemical and biological processes from the air-sea interface to the sea-floor. To understand these complex relationships between ocean processes, their forcings, and effects, long term time-series of Essential Ocean Variables (EOV) from fixed point (Eulerian) multidisciplinary observatories, monitoring processes that take place over much shorter periods of time, are critical.
In this session, we aim to share most recent research based on long term OceanSITES data sets or on long term time-series from eulerian multidisciplinary observatories not included in the network addressing air/sea exchange processes such as heat and freshwater fluxes, and ocean carbon and oxygen update; ocean transport, but also other biogeochemical, biological, and deep ocean processes. We welcome contributions which describe ocean variability at different time-scales from large-scale climatic fluctuations to hurricanes, and examine their governing mechanisms and environmental implications. Submissions focused on processes-oriented studies integrating different observing platforms (e.g. satellite, Argo floats, gliders, …) with long-term eulerian observation (moorings, ship-based time-series) are also encouraged as well as studies combining observations and modelling.
