Interannual Salinity in the Amazon Plume and Adjacent Areas (Poster)
Grodsky, S. and Carton, J. (23-May-17)

The main mode of interannual near surface salinity in the tropical western Atlantic is related to ENSO teleconnections and is produced by changes in precipitation over the ocean and Amazon. The ocean rainfall has an almost immediate impact on underlying salinity in contrast to the land rainfall that leads to a delayed impact related to the hydrology of Amazon system. Due to the need for longer time records to resolve interannual signal, our investigation relies on historical syntheses of in-situ observations mainly focusing on the JAMSTEC analysis. The inferred patterns of variability are compared to those from relatively short AQUARIUS records.
