PO33A:
Ocean Salinity and Water Cycle Variability and Change II


Session ID#: 11447

Session Description:
This session highlights new research investigating observed and modeled ocean variability and change, focusing on ocean salinity as an important driver of ocean circulation and upper­ocean mixing and a key indicator of the global water cycle. Recent observations, historical measurements, and model simulations have revealed oceanic variability and change on short (daily to seasonal) and longer (interannual to climate, >30­year) timescales. The SMOS and Aquarius/SAC­-D satellite missions present an unprecedented opportunity to monitor surface salinity and elucidate the ocean processes driving salinity variations on numerous timescales. Satellites complement in situ observations and process­ oriented field experiments, allowing researchers to develop a detailed understanding of the causes and consequences of salinity variability. Contributions are invited on all aspects of ocean salinity variations from the perspective of in situ and satellite observations, numerical models, and data assimilation. The session will focus on the following themes: new oceanographic insights based on SMOS and Aquarius satellite data; new process-­based insights obtained from field studies; the role of salinity in thermohaline circulation, upper ­ocean stratification, and ocean dynamics; links between salinity variability and global and regional climate variability modes and the fingerprint of long­ term change; and the assimilation of salinity observations into ocean models.
