Abstract
Observations of Near-Surface Salinity and Temperature Structure with Dual-Sensor Lagrangian Drifters During SPURS-2
Highlights
Despite the importance of sea surface salinity (SSS) as an indicator of the hydrological cycle (Rhein et al, 2013), many details of air-sea interaction responsible for freshwater fluxes and processes that determine near-surface salinity stratification and its variability are still poorly understood
The observed temperature and salinity differences between 0.4 m and 5 m depths are significantly correlated with each other for the following two regimes
(2) On the other hand, because rainwater is usually colder than the ocean’s surface, freshening during rainfall events is usually accompanied by a sizable surface cooling
Summary
Despite the importance of sea surface salinity (SSS) as an indicator of the hydrological cycle (Rhein et al, 2013), many details of air-sea interaction responsible for freshwater fluxes and processes that determine near-surface salinity stratification and its variability are still poorly understood. Freshening in the upper few meters due to rainfall events can exceed 1 psu (Drushka et al, 2016) and, can significantly contribute to the observed differences between satellite and Argo salinity data in regions of strong precipitation (Boutin et al, 2016).
